How to warm the wooden floors in a house with a cold preen: the better

Independent insulation of sex in private houses, which is carried out correctly, eliminates the owner from various inconveniences. In addition, it will make it possible to save on the services of masters and reduce spending on heating. To know how to insulate the floor in a private house, you need to get acquainted with the recommendations.

Floor insulation in a private house independently

In order to inside the room, comfort was felt, it is required to warm the floor. They, like walls, ceiling, window and doorways, are considered a source of significant heat loss. A similar problem is particularly relevant in the buildings that stand directly on the ground, without the basement. In such a situation, even intensive warming at home does not help. The presence of a cold basement under construction will not save. To know how to insulate the floor, you need to choose reliable material.

What materials can be used

Before carrying insulation of floors on the 1st floor at the cottage, in its own home, it is required to choose the case correctly. Experts recommend warming parquet mineral wool, clayzite, polystyrene foam, since these materials differ:

  • high techparameters;
  • duration of operation;
  • resistance to negative factors;
  • comfort in work;
  • inexpensive price.

When the homeowner has an old wooden dwelling without a basement, then the process of floor insulation should be started in a private house. Warming of coatings with their own hands is a rather complicated and time-consuming process. It takes a large amount of time and effort. However, similarly, the owner of the dwelling saves on the services of specialists.

It should be noted that when there is no required experience in carrying out construction and repair work, then optimally contact the masters. It is hardly in such a situation will be able to properly do the heat and waterproofing of the Ministry of Service or clay.

Important! It is recommended to invite qualified experts for the installation of qualitatively, quickly and at a relatively cheap price. They use reliable materials that are environmentally friendly, fire-resistant and durable.

Synthetic foamed insulation

Similar insulation are characterized by the following advantages:

  • moisture resistance, low moisture absorption;
  • The duration of operation will be 10 or more;
  • Resistance volume and forms;
  • have not been the negative impact of malicious microflora;
  • increased strength;
  • Ecology.

The small coefficient of moisture absorption and heat-conductivity of polyurethane foam makes it possible to apply the material to insulate the coatings on the soil. The thickness of the thermal insulation layer in a number of situations is 8 cm.

Mineral wool

Minvat is considered a construction insulation that consists of a large amount of fibers (there are 3 types: glass, stone or slags). To work with the trim, it is easier to use the basalt web, because it is easier to establish it under the design of the coating. Of the 2 options - rolls and mats as the plates - the second is selected because it is perfectly holding a form. Advantages:

  • good level of thermal insulation;
  • Easy installation;
  • relatively high moisture resistance;
  • heat resistance and fire safety;
  • Malicious flora does not start.

Minuses:

  • With independent installation, you need to use special protection - clothing, respiratory mask, glasses, because there are many particles of fibers and dust in the air, which irritate the dermis and respiratory tract;
  • It will take moisture protection, since the structure is sensitive to vaporization;
  • In violation of the installation technology, significant shrinkage is likely;
  • During the flooring between lags, the gap is made to the main design of 5 cm.

Important! When it was decided to use Minvatu, the insulation of the required thickness is selected. Specific parameters will depend on climate. Basalt wool is suitable for each type of coatings.

Ceramzit

Ceramzite is porous granules, which are made of clay, sand and small stone fractions, with further firing. A distinctive feature of such an outdoor insulation will be the possibility of preserving its own thermal insulating qualities in wet conditions. The following characteristics have made common:

  • Increased heat resistance;
  • resistance to temperature jumps;
  • increased fire resistance;
  • resistance to strong mechanical loads;
  • continued operation, which exceeds 40 years;
  • environmental friendliness;
  • ease of installation;
  • minor weight;
  • Reliability, insulated floor can stand for a long time.

By minuses include a large amount of material required for mounting. To make high-quality heat insulation, the clamping layer must have a thickness of 15-40 cm.

Main ways of insulation

Today there is a large list of technologies regarding insulation of coatings, which daily replenish new options with higher techniques. As a base, the railway plate, the black floor of the lags from the tree or the soil. Works should be carried out in a specific sequence.

Floor insulation

To insulate the grainsite floor of wood on the ground, it is required to follow the following recommendations:

  • An inspection of the base under the floor is made, it is falling asleep with fine-defective rubble at 10-15 cm, which will help to delay moisture from the soil. The interlayer is then rambling. To get the best effect, it is recommended to shed a crushed stone with water.
  • Then the sand is poured by a layer of 10 cm, carefully tram.
  • The waterproofing is laid on the sand on the sand - the ceramzite extremely strongly absorbs moisture and loses its own thermal insulation parameters. How waterproofing can be used runner and geotextile canvas.

  • After that, it is possible to pour a clamzite - the layer is 10 cm. After it is required carefully tamping. Fragile insulation particles are able to quickly collapse and contact dust, therefore should not overdo it. To achieve high-quality traaming, it is possible to mix small and medium particles of clay.
  • Steamproofing is mounted on the ceramic layer - it is enough to use polyethylene film. It is placed by the method of "peaks", the sizes of the joints must be at least 15 cm. Fixed a layer of vaporizolation to lags by construction scraps with a stapler.

Device heat insulation for floor by railway plate

Basic recommendations for installation work:

  • The coating is cleaned, aligned, the joints are closed with a solution.
  • A vapor barrier film with sizing seams is stacked when mineral insulation is used. Polystyrene do not need to be moisture.
  • Placed thermal insulation - slab, rolled, bulk.
  • Reinforced coating with a grid.

  • A sand-cement screed is poured.
  • Inside the wet room is placed waterproofing in order to protect material from moisture.
  • Mounted half-linoleum, tile, parquet, board.

Floor insulation for lags or overlap beams

Step-by-step instruction of insulation of the lagham coating:

  • Laggers are stacked on the supports with a special purpose.
  • At the bottom of the beam fastened a galvanized grid or a board.
  • The wind radiation membrane is spread, the seams are sampled, secured with a stapler to the bruus.

  • The material is stacked in a thickness that is not less than the calculated for a particular climatic region.
  • The materials from moisture with hydrooparasolation are isolated on top of insulating, fastened to lags, the seams are sinking.
  • From above design, plywood or board is fixed to the crate. This will be the basis for the finish coating.

Important! In a number of situations, thermal insulation is placed in 2 layers. In this case, Bruks 2 levels are set perpendicular to the first.

Floor insulation using double floor laying

This method is used when the height of the ceiling makes it possible to reduce this indicator by 12-20 cm. Basic Tips:

  • The plinth is removed, the flooring is repaired and the gaps are filled with mounting foam, sawdust with carbon black glue or tired paper with a hub;
  • lags are installed with a distance between them 0.6 m;
  • Vaterpas is measured by the height of the upper planes of the lag, with exceeding the belts are removed, the flaw is eliminated by lining under the rubberoid bar or chips;

  • The hydraulic vapor insulation is placed;
  • The cavity of the lags is filled using clay, basalt wool, foamed polystyrene or other thermal insulation material, leaving the gap for ventilation;
  • The floor is covered by the next layer of isolation;
  • The board, plywood or other similar material is laid;
  • At the end, the flooring is placed, plinth is installed.

Important! Regardless of the selected scheme, coating in pile bases, it is required to protect against blowing with a windproof barrier. It is located on the outdoor side of the insulating system.

How to insulate the floor from below without removing the old floor

When there is a cold basement in a frame house, optimally insulate the floor from below, without removing the old coating. At the same time, you will not need to select a material that is able to withstand a mass of heavy furniture items and other mechanical loads. In such a situation, the defense of the final coating and the entire floor is performed.

During the fulfillment of installation work, certain difficulties appear with rapid fatigue from work with raised hands. In addition, there are prohibitions about some types of thermal insulation and the need for fastening with high reliability.

Insulation from the bottom in the following way:

  1. Initially, it is equipped with waterproofing.
  2. Next is the heat insulator.
  3. The insulation from water vapor is installed on top.
  4. Then the overlap is made, which will hold the heat insulation of the coating.

Important! Observing such technology during the work itself, it is possible to obtain an acceptable temperature mode in the dwelling. The insulation should not have a big weight because it gives a strong load on the fasteners.

Tips and recommendations

Recommendations for installation work:

  • For the purpose of thermal insulation of coatings, various materials are suitable characterized by reliability and low thermal conductivity.
  • The greatest effect will give layered isolation.
  • Fibrous, porous and bulk materials are optimally positioned from a cold side - thus inside the room will return a larger amount of heat.
  • To avoid dismantling the coating, in a number of situations, the heat insulation of the floors on the 1st floor is performed from the basement side.
  • To insulate the floor with a clamzite, optimally use the material with porous granules - they hold in the room to 80% of heat.
  • Regardless of the material used, it is necessary to carefully examine the coating base. It should have no gaps and flaws. When they are revealed, close up with the help of a mounting foam to prevent the formation of "cold bridges" in the future.

The warm floor will be the key to creating a comfort and comfort in the dwelling. When the high-quality heat insulation of the floor was not performed, the temperature indicators indoors will be low even with the proper operation of the heating system. The process of independent insulation of the coating is not an extremely difficult task, so it is possible to fulfill it even without the help of specialists.

In domestic climatic conditions, the need for the insulation of residential buildings does not cause any doubt. Owners of private houses have to solve this problem on their own. Wooden boards, of which, in most cases, floors are manufactured in country households, are deformed over time, and enlightements appear in a tightly shot down.

It is difficult to imagine, but through these cracks during the cold season it can leave up to thirty percent of thermal energy. As a result, heating costs increase sharply, the comfort of living in the winter period is reduced. To prevent these consequences, it is necessary to warm the floors qualitatively.

Wood floor insulation
The list of materials for the insulation of the floor is quite wide

Wood floor insulation techniques

The heat insulation procedure of the wooden floor should be foreseen at the design and construction stage of the house, and then the minimum labor and financial resources will be required. If it is necessary to perform this manipulation, when the overlap is already ready, the performance of work is significantly complicated. In this case, it is possible to work correctly and insulate the floor can be on top, right on old coating, or with its partial dismantling. There is also an option of insulation of flooring from the bottom from the basement.

Floor insulation
In this case, it is more convenient to warm the floor from the basement side

Heat insulation is made from above, if there is a low basement in the house. If at the same time the flooring is dismantled, only lags are left. The procedure is characterized by a lot of labor intensity. In the event that the basement of sufficient depth, laying the insulating material can be made from below. It is much easier and faster, since in the process of performing work does not have to dismantle and disassemble the flooring if it is in good condition.

The better the floors in the private house

Floor insulation in a private house do it yourself quite real. This uses a variety of heat insulating materials. Which one is better, is determined after analyzing their performance and specific conditions in which they will be operated. The insulated floor significantly increases the comfort of living in the house at negative ambient temperatures and reduces heating costs.

Floor insulation Eco-friendly
Equata - one of the options of insulation for wood floor

The foam and expanded foam and polystyrene are widely used, the use of glass gambles and mineral wool has its own characteristics. The most simple and lowest method of insulation of the surface of the wooden floor with clay or with wood sawdust. Not bad performance characteristics are the so-called dry screed.

Advantages and disadvantages of foam and expanded polystyrene

Many people know that you can warm the floor with polyfoam. Polystyrene foam for sex is also popular with professional builders and home masters. Polyfoam and expanded polystyrene, due to their excellent operational qualities, were widely used as insulating materials. With the exception of minor differences, their technical characteristics are comparable to each other. The use of these thermal insulation materials carries the following advantages:

  • low cost;
  • low thermal conductivity;
  • a small mass;
  • a wide range of use;
  • long service life;
  • resistance to the effects of pathogenic microflora;
  • Install installation.
Floor insulation Foam
Quite often the floor insulate foam

In addition to the above advantages, these materials have operational disadvantages. Their list is also quite impressive, the following negative qualities can be noted:

  • distinguished harmful substances with ignition;
  • prevent the passage of water vapor;
  • afraid of exposure to direct sunlight;
  • attractive for rodents;
  • are destroyed upon contact with solvents;
  • Have low mechanical strength.

Characteristics of the "dry screed" for insulation of floors

The so-called "dry screed", which is made from plaster fiber, is perfect for the thermal insulation of the wooden floor of the private house. The use of this composition involves the following positive parties:

  • excellent thermal insulation;
  • fire safety;
  • ease of laying;
  • compatibility with all finishing coatings;
  • a small thickness;
  • Good characteristics of noise absorption.
Warming "dry tie"
The process of laying a "dry screed" for floor insulation

At the same time, since we will warm the floor with a dry mixture of factory manufacture, it is necessary to take into account its high consumption: the processing of one square meter of the surface requires twenty kilograms of the mixture. In addition, when water penetration, the geometric dimensions of the dry screed change, which can lead to a deterioration of the final coating.

The possibility of using mineral wool

Mineral wool is widely used to provide heat insulation of wooden floors. The material is made in the form of plates that are easy to put on the floor with their own hands.

Floor insulation Minvata
Mineral wool is well suited for floor insulation

Mineral wool has many positive properties. The material is distinguished by magnificent noise absorbing and insulating qualities, fire safety, prevents the multiplication of pathogenic microflora, racks to the effects of aggressive chemical environments.

However, when water enters the water, the deformation and partial loss of heat insulating qualities occurs. In addition, mineral wool has low mechanical strength and does not apply to environmentally friendly materials.

Features of glass gaming

Glasswater is similar in its characteristics with mineral wool. A feature of its application is that when performing work, it is necessary to carefully ensure that it does not get into organs of vision or skin cover.

Floor insulation glass
Glasswater - Common Wood Floor insulation

The production process is complicated by the need to use by an employee of individual means of protection. The negative quality of this material is its significant shrinkage over time, as a result, with incorrect laying there is a disruption of thermal insulation.

Pros and disadvantages of using clay

Ceramzit is made on clay-based foamed and burned granules of porous structure. The big plus of this material is low cost, environmental purity, small weight and long service life, which is about fifty years. Ceramzite has excellent insulating and insulating qualities. Thus, the thermal insulation of the surface of the wooden floor with a clamzite does not break the shape in the family budget.

Floor insulation ceramzit
Floor insulation with clay - simple and inexpensive

Its use of its use can be considered the need to perform a considerable layer of frustration, otherwise wooden floors will remain cold, especially with sharply negative ambient temperatures. In addition, it absorbs moisture well, although not losing insulation properties.

Sawdust - the cheapest material

The cheapest value of the material is finely crushed wood sawdust. They do not represent any danger to human health, the technology of performance of work is extremely simple: sawdusts are covered between the draft and the floor-coated floor. Before use, this material must be carefully drained at least twelve months, otherwise it will quickly come into disrepair. Waste cut freshly edged trees can not be immediately applied.

Floor insulation sawdust
Apparently, sawdust is the most budget version of the floor insulation.

An increase or decrease in the layer thickness is regulated by the heat insulation level. In the northern regions with a very cold climate, you have to pour a very thick layer. It is necessary to take into account the attractiveness of this material for rodents and to release them to add to the composition of the two parts of the harated lime in a dry form. The disadvantage of wood sawdust is the emergence of rotation processes in them during wetting.

Modern selection - Clear and Penophol

Undoubted operational advantages are characterized by the use of such modern materials as insulation such as isolon and foam. Cellon is a foam polyethylene coated foam layer and has excellent sound-insulating qualities with a very small thickness. The material does not support combustion, prevents the development of pathogenic microflora and corrosion processes, the two-chaser layer is comparable by soundproofing and heat-saving properties with masonry in one brick.

Floor insulation Penosol
Fragments of styling of foamizol for floor insulation

The foam produced in the form of rolls consists of several layers of insulation, on top of which is a reflective foil. It serves as a screen that prevents high losses of thermal energy.

When using foam, it is not necessary to carry out additional waterproofing work or the archoland of a vapor barrier layer.

The easiest way is to lay a double floor

The easiest way to perform insulation is to provide at the stage of building a house laying double floor, which is a draft and finishing coating. Such a system of insulation should be used in a room with high ceilings, as you have to occupy useful space.

Building technology provides for the laying of the Lag, on which the draft floor will be strengthened. The coating can be made from wooden boards, chipboard, OSB or other similar materials, it is only important that the structural elements are tightly fit to each other without forming gaps.

Double floor
Double floor arrangement - reliable insulation option

In the surface of the draft floor between the guides, insulating material is stacked. At the same time, it should not be used in its quality sand at high natural humidity, since in this case the formation of condensation is possible. On top of the insulation, a blank coating of wooden boards with a thickness of about five centimeters is mounted. A new coating will have to paint, as described in the article "How to paint in the house wooden floors of paint or covered with your own hands."

Of course, the old floor can be insulated in the same way, however, it should be taken into account a decrease in the relative height of the ceiling.

The most correct insulation of the floor - on lags

When building a new home or dismantling the coating, the most proper insulation of the floor is the method of performing lags. In this case, the insulation is located between the lags, which serve as the basis for the first floor. Depending on the construction of the building, the basis for the installation of lag and the insulation can serve as a rough floor, made on its own lags, as well as concrete coating or even ground. In the latter case, it is useful to equip a clay castle to protect against moisture layer of about 5-10 cm.

Warming between lagami
Dense insulation can be held between lags on ordinary nails

In the technology under consideration, the height of the lag and the distance between them should correspond to the height of the insulation and its width. Before mounting the floor covering over the insulation, the vapor insulation layer from the waterproof film fixed on the lags should be equipped. The junctions of the film can be fixed with scotch.

How to insulate the floors do it yourself from the bottom, without removing the old floor

If a private house has a deep cold basement, the most correct way will perform insulation of the floor from the bottom, without removing the old coating. It does not need to choose a material that can withstand heavy furniture weights and other mechanical loads. In this case, the defense will be performed not only the pure surface, but also the overlap as a whole, and the overlapping dew point will move outward, and the coating will not be rotated.

When performing such a task, some difficulties consist in rapid fatigue when working with constantly raised hands. There are also restrictions on the types of heat insulating material and the need for its fastening with increased reliability.

Schematically, the insulation is performed as follows:

  • Initially, the waterproofing layer is shown;
  • Then there is a heat insulator;
  • on top of it isolation from water vapor;
  • Next, the overlap is performed, ensuring the hold of the heat insulation of the floor.
Foam insulation from below
Polyfoam can be fixed from bottom to nails with gaskets and mounting foam

Adhering to such technology when performing work with your own hands, you can get the most comfortable temperature regime in the residential premises of the house. The heat insulator must be a small weight, as it will have a permanent load on the attachments, the bulk materials in this case are not suitable.

Floor insulation in a wooden house from the inside by foam or glass wool

Good results give insulation from the inside by foam or glass wool. These materials are distinguished by low weight and remarkable heat insulating qualities. At first, waterproofing is fixed to the lower surface of the overlap with a stapler. Next, it is possible to lay insulation plates in such a way that they retain during installation due to the friction force. For this, their width should be a little more distance between the lags. When working with glass, it is necessary to use individual means of protecting the respiration organs, vision and skin.

Penoplex for floor insulation
Penoplex - reliable wood floor insulation

On top of the insulation, a vapor barrier film is superimposed, which is attached to lags using brackets and stapler. Next, the lags are mounted a frame that holds the insulation. It can be made of any material that will suit you in appearance and durability. Between the holding elements are allowed, intervals are allowed through which the insulation will not fall out.

Step-by-step manual insulation of wooden floor polyurethane

Currently, the widespread the heat insulation of the wooden floor is polyurethane. To perform this work, it is necessary to pre-prepare the basis for which the eco-board will be applied, and spray the composition on the lower surface of the overlap. Step-by-step instruction looks like this:

  • The coating is cleaned of contamination and is carefully degreased;
  • It is dried to the base to humidity of no more than five percent;
  • High pressure installation is connected by hoses to tanks with mixture components;
  • Polyurethane foam is a uniform layer spreads over the floor surface;
  • The drying time of the coating occurs within two days from the moment of applying.
Insulation polyurethane foam
It is quite realistic to insulate the wooden floors below the polyurethane foam

High pressure equipment by which polyurethane foam is sprayed, it is very expensive. Acquire it for the arrangement of thermal insulation in a private house is irrational and better to take this equipment for rent.

Heal insulation in a private house do it yourself on the old floor

Reading time ≈ 11 minutes

Energy savings in their own housing is not an empty sound - this is a real problem, which is directly proportional to the comfort and financial position of the family. In this regard, sometimes the question arises about how to insulate the floors in a private house do not remove the old floor, that is, in fact, to mount the budget, but at the same time a qualitative version of insulation. This desire can in any way be attributed to whims or something impossible - here the most important thing is the right approach to the situation and this requires certain knowledge.

In what cases is a floor insulation

Heal insulation in a private house do it yourself on the old floor

The principle of insulation of any sex

More than once it was necessary to deal with situations where the tenants of the house or apartment asked to assist in the insulation of the floor to at least somehow lower heating costs. But the thing is that it is not always correct and isolation is not needed on the floor, but on the walls or ceiling, or it is not needed at all - the problem is in bad windows and the entrance door.

In what cases the floor need insulation:

  • This is the first floor of a private house, where concrete floors close to the soil are laid as a draft base;
  • The first floor of an apartment building - the cold penetrates the basement;
  • under the floor there is a cellar or basement;
  • Private house built in the northern region;
  • Required sound insulation.

What materials are used in such cases

Heal insulation in a private house do it yourself on the old floor

Extruded expanded polystyrenex (penoplex) of different thickness

If you can mount insulation on top of the old floor, then it is assumed that the conclusion that the material cannot be loose, but it must necessarily be thin. Such conclusions are definitely true, but only partly, since in some cases thick, and sometimes bulk isolation products are suitable.

What materials can be used:

  1. Epps.
  2. EPS.
  3. Xps ..
  4. Penopelex.
  5. Pollan.
  6. TechnoNIKOL.
  7. Etc.
  1. Glasswater - Currently practically not used for domestic purposes.
  2. Slotovat - made from the melts of a domain slag. Because of the particles of iron (Fe), which remain there, the material is undesirable to use indoors with high humidity.
  3. Kamnevat - also known as basalt wool. It is manufactured from the melts of volcanic eruptions (basalts) and is considered the best of all three technical and technological terms, but at the same time, the most expensive.
  • Styrofoam. In appearance, extrusion is very similar, but it is simply foamed plastic with filled with air cells and less density (15-25 kg / m3). The thickness of the panels from 20mm to 200 mm. Marking as PSB and PSB-C (not lit, only melts).
  • Penosole. It is also called liquid foam, but in fact, it is a carbamy-formaldehyde foam (CFP) in liquid form. Its density in the solidified state can be 6-60 kg / m3, but the construction uses options from 10 to 15 kg / m3.
  • Penophol. This material refers to reflective thermal insulation, as it is a foamed polyethylene with one or two sides coated with aluminum foil. It is made exclusively in rolls, its thickness is from 2 to 10 mm.
  • Bung. As a rule, it is used as a substrate for laminate and linoleum. It serves as heat and insulation of the absorbing type.
  • Ceramzit. This is a very lightweight solid porous material, which is obtained by firing clay shale or clean clay. Its density ranges from 350 to 650 kg / m3. There are four fractions of the material determined by the magnitude of the grain:
  1. Large - 20-40 mm.
  2. Average - 10-20 mm.
  3. Small - 5-10 mm.
  4. Sand - up to 5 mm.

Some methods of insulation on top of the facial flooring

Consider all the options how to insulate floors in a private house with your own hands without removing the old floor there is no point, since some simply look like technical performance. Therefore, we will focus your attention not on materials that, by the way, are already listed above, but in the ways that you can achieve the desired result.

All work begins with the definition of zero or a finite level of facial coating, and this in this case is an instruction for laying all the materials listed above. That is, before proceeding to the installation of the root, it is necessary to calculate the height of the ceilings and determine which distance you can donate, since not all rooms can be very high. In the time of the USSR, everything was simple with this question: the living room had at least 2.5 m of height, but now everything has changed. Thus, to lower the ceilings can be from 2.2 to 2.7 m high, but it is convenient, for example, the Chinese with an average increase of 165 cm, but the Europeans has such norms at least in two meters may cause a sense of discomfort.

Installing lag over the old floor

Heal insulation in a private house do it yourself on the old floor

Lags can be installed on top of the old floor, without removing the coatings

Imagine that we have the opportunity to raise the floor by 10 cm, but this is not the thickness of the insulation, but zero, which can at a certain height of the room. For insulation, it is more expedient to use lumber to use lumber as a facial coating: boards, moisture-proof or laminated fane, as well as a fission-oriented stroke plate 3-4 class of strength and moisture resistance (OSB-3, OSB-4). However, other facing materials such as linoleum, carpet or laminate can be treated on wood, which is no longer included in the determination of height.

The thickness of the boards in this situation should be 25-30 mm, but this is only if the lags are installed in a step of no more than 400-500 mm - with increasing step, the thickness of the board increases. If plywood or osp leaf materials are used, then the step should also withstand no more than 400-500 mm, although the allowable thickness of the sheets can already be 18-20 mm.

But before installing lags over the old floor, without removing the facial coating, it should be verified in its mechanical strength and integrity, it is especially important for wooden structures. It may be that the floor has become cold due to dampness, and this in turn destroyed wood (flooring and / or lags). In this case, the repair of damaged sites is necessary - it is still easier than the complete replacement. In cases where the dampness did not disappear or on wood, a fungal mold was found, it is categorically not recommended from above to carry out any other coating! Installation is possible only if the old floor is integer, dry and there is no dampness and fungal mold.

You can use a bar as a lag, but it is not rational - it is much more profitable to apply a 50 mm thick board, for example, 50 × 100 or 50 × 70 mm, or a 50 × 50 mm bar. To the floor, such beams are usually fixed with plastic dowels and long screws, but all profiles should be set strictly by level.

Insulation of foam and mineral wool

Floor insulation foam on top of a ceramic parquet

This method of laying insulation is most suitable for mineral wool and foam, although no one forbids using extruded polystyrene foam of any brand as an insulation. Panels or mats are stacked between lags, trying to press them close to eliminate most of the slots and gaps, although it is impossible in practice, but it is not critical.

In the case of laying mineral wool of any type (roller or in stoves), all the remaining gaps close up the crop materials that will definitely remain when installing. The width of the mat's basalt wool according to the standard is 450 mm, therefore, the distance between two edges (not centers) of the beams should leave about 400-420 mm so that the stove is tightly entering the seat.

When laying foam plastic, where the panel has a standard 1000 × 1000 mm, it can be cut exactly in half, that is, on two fragments of 500 × 1000 mm. Lags are installed so that their side walls are at a distance of 497-499 mm. No, this is not at all the highest pilotat, you just should try to make the PSB-C sheets close to the landing place, but if there is no place to be a gap, then this is not critical. All the gaps and small gaps blow the mounting vein, which is not even necessarily cut after drying.

Warming Penosol

Heal insulation in a private house do it yourself on the old floor

Wooden floor insulation by foamizol

Penosaol or carbamide-formaldehyde foam (CFP) is in most cases used for floor insulation, although it can also be used for walls, for example, to blew in the sparkle masonry. Blowing foamizol can be coated (boards, phaneur, OSP), and without it, although it is best to use the second option, since the level of material filling between lags is visible in the open space. The carbamy-formaldehyde foam has one good feature: it does not increase when drying, as a mounting foam, therefore, the level that was established initially and remains to the end. This allows you to provide the desired distance (20-25 mm) for the ventilation gap between the facial coating and the CFP.

Floor insulation by extruded polystyrene foam under laminate

Materials such as extruded polystyrene foam and traffic jam are widely popular for floor insulation, but most often they are bought in rolls and are used as a substrate for laminate or linoleum. But it is also possible to apply other modifications of such materials, this is a plate execution of products. In order for no one in doubt, I will say that when installing the fastener or traffic jams on the floor, in the panels it is easy to go legs and no dents remain, although they are easily cut into a knife. That is, you can set the floor with Epps panels, for example, 30 mm thick and straight on top of it to lay a parquet board, laminate, phaneer or OSP. It is allowed to install any rigid floating gender.

When a film warm floor is carried out, then the reflector is usually placed below, and this is most often a foam or foil foamed polyethylene. That is, the material itself can be used and as a conventional insulating substrate under the laminate, but here is a special case. The IPO or infrared film heater does not hear the room, but the IR rays are reflected from the items and falling onto a person, create the effect of heat, while maintaining the air fresh. Aluminum foil, which is covered in this case, the substrate is the best reflector of IR radiation, therefore, its choice in such cases is best stopped on the foam.

Laying dry screed on clay sand

The dry screed of itself is warm, since its main component is a material that is poorly conductive thermal energy, it is a grainzite of small fraction or clay sand. In fact, in this case, you are one shot, so to speak, kill two hares, one of which is the cold floor, and the other is the lack of a flat base for any facial coating. A dry tie can be mounted not only on concrete ceilings, but also wooden and mineral (concrete, ceramic tile) floor.

Conclusion

As you can see, the question of how to insulate the floors in a private house does not remove the old floor, does not constitute any difficult, and even more so, an intractable problem. As you notice, in the description were used, let's say, the fundamental methods, but in the videos used Lifehaki - choose what you like to taste!

How to insulate floors in a private house do it yourself without removing the old floor - instruction

In connection with the general tendency to reduce housing heating costs, the issue of floating floors. Hota Paul gives a smaller heat into the atmosphere than walls, in a cold condition, it can reduce the accommodation temperature and lead to excessive heating costs. In a private house, cold floors can lead to frequent respiratory diseases at its inhabitants.

How to insulate the floors in a private house do it yourself

There are several ways to insulate the floors in a private house with your own hands on a removable old floor. They differ depending on the type of outdoor coating already available, the works themselves have a different degree of complexity.

Warming without removing the old coating is relevant for those houses in which the floor carries a structural function and serves as the roof for basement rooms.

Features of insulation from steam

Wooden floors in a private house are easiest to be warming up with their own hands, it is easy to spend, without removing the old floor. The tree is easy to handle, it is easy to isolate. In wooden floors there must be such insulation layers:

  1. Parosolation
  2. Insulation
  3. Flooring

For insulation from steam, modern materials can be used, which passes air, but delay moisture. Vaporizolation is one of the main components of insulation, without it, the floor is quickly wearing, and the desired effect of energy savings is not achieved.

Isolation from para

Purchase desirable vaporizing materials of well-known firms sold in specialized stores. This will avoid fakes and give a guarantee of simple operation.

Material for insulation

After selecting vaporizolation material, decide on the insulation. The market offers many materials possessing both advantages and disadvantages. Here are their list:

Polystyrene plates Regarding inexpensive, possess good operational qualities and a large variety of sizes. They can be laid in one, or several layers. They are not amenable to biological decomposition, easy to install, durable and well hold the shape.

Polystyrene plates for insulation

Plates of extruded polystyrene From the previous species differs in high density, which allows you to lay them on any, including the ground surface.

Plates of extruded polystyrene for insulation

Polyurethane foral plates Used only on a vapor barrier basis. They are strengthened by different substances, it can be fiberglass, aluminum, or other materials.

Polyurethane foam plates for insulation

Mineral wool It has excellent thermal insulation properties. It is very environmentally friendly, it does not burn, it is inexpensive and does not require additional techniques when laying. This wool is a soft material sold in large rolls.

Mineral wool for insulation

Warming with clay Requires considerable effort, it should be traaming and pouring cement.

The choice of material for insulation depends on financial and technical capabilities in each case.

Preliminary preparation

Before insulation of the floors in a private house, do with their own hands without removing the old floor, you need to prepare work, which will make the room suitable for laying thermal insulation:

  • Inspect the underground space for the presence of high humidity.
  • Build ventilation basement.

Preliminary preparation for floor insulation

If these moments ignore B, from the bottom of the floor, condensate will accumulate, provoking the growth of mold fungi. It is almost impossible to get rid of mold, so it's better to prevent her appearance from the very beginning.

Old wooden laying process

In order for their own hands to insulate the floors in a private house without resorting to the removal of the old floor, such building materials should be collected:

  1. Stucco or mounting foam
  2. Sand
  3. Lesters Ruberoid
  4. Parosolation material
  5. Construction Stapler or Nails
  6. Heat insulator
  7. Plates chipboard

With the help of materials from the first point, the slots between the boards of the old coating are embarrassed. The floor prepared in this way is covered with rubberoid, sand is embanked from above. Its layer should be no more than 0.5 cm in thickness.

Next, the process of laying the floor occurs according to the following instruction.

Steam insulation material is stacked over the sand. Depending on its thickness, nails or staples of the construction stapler are used.

Steam insulation material laying

The insulation itself is stacked on vaporizolation. It also needs to be fixed with nails of suitable length.

Laying insulation

A chipboard is laid on top of the insulation layer. It will be mounted onto the outside flooring - parquet, laminate, or other options.

Laying chipboard on insulation

This method is suitable for floors with wooden coating. For buildings with a concrete basis, a slightly different styling technique is used.

Concrete floor

There is a simple and convenient method, how to insulate your hands the floors of a private house without removing the old concrete floor. First of all, you need to carry out the so-called floor screed. It is necessary for aligning the coating and bringing all the floors in the house to one height. For a simple and inexpensive dry screed, such materials are required:

  • Gypsum Based Plates
  • Polystyrene.
  • PVA glue
  • Selfless

This type of screed is extremely easy to install. The floor is covered with a polystyrene, its surface is aligned. The plates are stacked on top of the polystyrene. Their joints are missed by glue, screws are used for greater strength.

Next, the insulation of the floor passes according to the instructions below.

A vapor insulation coating is stacked on the slab , It is fixed with a nail or stapler. You can purchase a vapor insulator of the same manufacturer as the slabs for the screed.

Parosolation stacked on the slabs

The insulation is stacked on top of vaporizolation , It is also fixed.

After that, you need to carry out the finish tie. You can use chipboard for it, as in the case of a wooden floor, or apply the same tie plates that have formed the basis of insulation.

The finish tie with plates should be projected. The first layer of primer is applied to the joints, he must dry well.

After drying the jacks, the primer is distributed over the entire floor surface. Immediately after its drying, it is possible to lay a pure floor covering.

Floor insulation in a private house with their own hands is a good task, and it can be solved without attracting professional builders. The main thing is to determine the choice of thermal insulation material and with the technology of insulating work. This will largely depend on the structure of the floor.

Paul insulation in a private house do it yourself

Paul insulation in a private house do it yourself

It is necessary to insulate the floor in any case, referring to this task with the maximum responsibility. Without this, there is never to create comfortable living conditions in the house, even if we spend huge funds for the work of the most perfect heating system and other climatic equipment. Beth thermal insulation is money for the wind!

The publication will consider the materials used for thermal insulation, various insulation technologies, depending on the design of the floors.

Materials for insulation floors in a private house

The first thing you need to do is to determine the choice of thermal insulation material that is suitable for the floor of a particular design. Therefore, when considering the characteristics of insulation, it will immediately be noted, for what gender they are suitable, and an overview of the technology of their application will be given.

So, today for thermal insulation of floors, mineral wool (glass and basalt), polystyrene foams of various types and ceramzite are most often used. It should be noted that there are other materials for insulation, for example, eco-water or polyurethane foam. However, to use them will require special equipment and experience with it. That is, under the category "do it yourself", they are difficult to bring them.

There are other, let's say so - more "exotic" insulation, such as plates of foam glass or cork. But they have not yet received special distribution, apparently, in view of increasingly available or excessively high prices. Our article is designed for the average home owner who wants to perform insulation on their own.

Synthetic foamed insulation

This group includes the most applied thermal insulation materials today - this is an ordinary white foam, extruded polystyrene foam and foamed polyethylene (ISOFLEX reviews). These insulation obtained their popularity due to low thermal conductivity and quite affordable cost. In addition, foamed materials have a number of other advantages, but they have very significant disadvantages.

Extruded expanded polystyrene foam

This material is made from the same raw materials as a friendly white foam, but on a completely different technology. Therefore, it has improved characteristics.

The polystyrene foam can have different characteristics. For insulation of floors, it is better to use extruded as more durable and having high thermal insulating abilities.

The polystyrene foam can have different characteristics. For insulation of floors, it is better to use extruded as more durable and having high thermal insulating abilities.

White foam is better at all as a heater for floors not to consider, also the insulation of the foundation of the foam is better not to produce. Honestly, he is not at all a place in the system of internal insulation of a residential building - too much disadvantages, including - extremely dangerous for a person. At extruded material, these "minuses" are still significantly reduced. Therefore, it is better to carry out insulation of sex by penplex - this is exactly what is referred to as extruded polystyrene foam.

The insulation of the Painoplex insulation, or polystyrene foaming enters the plates of clear geometric forms of various thickness. Its low thermal conductivity is explained by a closed porous structure of a material that is more than 90% percent consists of air.

The advantages of extruded polystyrene can be called its following characteristics:

  • High levels of thermal insulation, since the thermal conductivity of the material is only 0.030 0.035 W / (M × K).
  • The material has a low level of moisture absorption, that is, even in the most unfavorable conditions will not accumulate moisture, losing in its insulation qualities.
  • Long service life (with good protection against ultraviolet rays), measured by several decades.
  • Qualitative extruded expanded polystyrene is obtained by a special processing that helps to reduce its margins.
  • Inertia to biological striking.
  • Ease of installation and processing.

However, it has this thermal insulator and its shortcomings:

  • The composition of polystyrene foam includes a compounds unsuccessful for a person, which simply with time, or under the influence of ultraviolet, are able to stand out into the environment.
  • When exposed to open fire, the material flashes, melts, spreads, continuing to burn and spread fire. The toxic smoke from burning polystyrene foam is extremely dangerous, and often it becomes the main reason for the tragedies during fires.
  • Perepecility is another conditional drawback of this material. True, he often refers to dignity - it all depends on the site of the insulation. By the way, for the first floor floors is just more pulls on positive quality.
The extruded polystyrene foam is great for the insulation of floors on the ground or along the concrete overlap of the subsequent fill of the reinforced tie.

The extruded polystyrene foam is great for the insulation of floors on the ground or along the concrete overlap of the subsequent fill of the reinforced tie.

The extruded polystyrene foam in a private house is often used for insulation of floors on the soil. After laying the thermal insulating layer, it is poured by a reinforced tie, which will already become the basis for any floor covering. And in the closed concrete of polystyrene foaming no longer so acutely manifested by its characteristic disadvantages - the emission of styrene and the inconvenacity to the fire.

The floor of the first floor of a private house can be a reinforced concrete slab overlapping over a cold underground. But the insulation diagram at the same time does not undergo special, fundamental changes.

Schemes for the use of polystyrene foam when insulation of sex on the soil and for reinforced concrete overlap.

Schemes for the use of polystyrene foam when insulation of sex on the soil and for reinforced concrete overlap.

The plates of polystyrene foam and for thermal insulation of the wooden floor, with the placement of the insulation in the space between the lags or the beams of overlapping is used. But with this option, do not forget about the shortcomings of this material.

Polyethylene foamed

Polyethylene foamed is often used as a substrate for rigid floor coverings, for example, under a laminate or parquet board, or is used in a complex with other insulation to enhance the overall thermal insulation efficiency.

Foamed polyethylene used as an elastic substrate.

Foamed polyethylene used as an elastic substrate.

Foamed polyethylene goes on sale in rolls 1000 ÷ 1200 mm wide. Material is easy, elastic, easy to work. Among the positive qualities of this material, the following can be distinguished:

Foil polyethylene foam is capable of becoming a steamproof obstacle, as well as create a "thermos effect", reflecting the accumulated heat back to the room.

Foil polyethylene foam is capable of becoming a steamproof obstacle, as well as create a "thermos effect", reflecting the accumulated heat back to the room.

  • Low thermal conductivity coefficient - about 0.037 W / m × K.
  • Polyethylene foamed, although it looks like a sponge, thanks to a closed porous structure, moisture is not drinking and can even be used in waterproofing systems.
  • Damped, depreciation quality material cause a good effect of absorption of sound and shock noise.
  • The material is not subject to biological decomposition, racks to most chemically active substances that can meet in everyday life.
  • Foil polyethylene has heat-resistant ability.

The disadvantages of this material are the following features:

  • Flavoring insulation, it refers to a combustibility group G2 ÷ g4.
  • Low heat resistance - with elevated temperatures, the material begins to "swim"
  • Low vapor permeability, that is, the material is not breathing. Again, it is sometimes explicit dignity.
  • Low strength of a thin insulation on a break and compression.

As a substrate, an ordinary foamed polyethylene is up to 3 mm thick. A folgized version can be on top of other hard insulation, or also as a reflective substrate. In addition, the foil material is usually placed under the "warm floor" system, and any of its possible varieties - electrical cable or film infrared, water, warm floor under linoleum or other flooring.

Sealing foil polyethylene with special scotch.

Sealing foil polyethylene with special scotch.

Foamed polyethylene canvas stacked jack and sealed with fluolized tape. The coating should be sealed, since it is very often a layer of foil polyethylene foam is considered as the necessary vaporizolation barrier.

So, the material is very good, but only calculated on joint use with other insulation. Relying on the fact that only its use can create a full-fledged efficient thermal insulation of the floor of the first floor of a private house - just naive.

Mineral wool

On sale you can meet three types of mineral wool - it is a stone (basalt), glass and slag. Shelotte is practically not applied in housing construction, as it has no outstanding characteristics, and often does not comply with the requirements of sanitary standards. Therefore, the features of this type of insulation will not be considered.

Mineral wool - effective insulation for different parts of thermal insulation at home

Basalt and glass wool are also characterized by their characteristics, but both of these types are widely used in insulating structures. They will be considered in more detail.

Glass Vata.

Glasswater is made from environmentally friendly raw materials - this is sand, glass battle, borax, soda and limestone. Fibers are formed from the melt of materials, quite fragile and brittle, but when they pressing them in mats using binders, it is sufficiently sufficiently stable air-saturated structure with high insulating abilities.

Plates or mats glass gambles typically distinguishes a clear yellowish tint

Plates or mats glass gambles typically distinguishes a clear yellowish tint

The glass gamble can have a different thickness, possess different density, produced in the usual and foil form. When used for the insulation of the floor of the second variant, mats or stoves foil up, that is, towards the room. Due to this, heat from the room falling on the insulation is reflected back.

Glasswater has a lot of advantages. Here you can attribute high thermal insulation capabilities, rather high heat resistance, fire resistance and chemistry, the available value of the material.

Disadvantages - pretty high fiber fragility. This creates difficulties in work - the stuff material, capable of causeing strong irritation of the skin, respiratory and mucous membranes. In addition, such a brittleness is a prerequisite for the gradual shrinkage of the material during operation, special, if there are vibration loads. And this leads to a decrease in thermal insulation characteristics.

In addition, not all safely in glass gambles and with water exposure - it can get into and embrace their insulating qualities. Must require measures to prevent its saturation of moisture.

Stone (basalt) wool

Stone wool has the most optimal characteristics of all types of insulation of such a class. This thermal insulation material is made from the melt of basalt rocks, from which thin fibers are pulled out, which are much stronger and more elastic glass.

Plates of basalt insulation.

Plates of basalt insulation.

High-quality basalt insulation are the most stable moisture. Such stability is achieved by special treatment, and sometimes reaches practically to hydrophobicity - water does not penetrate into the structure of the material.

Basalt wool master manufacturers have high resistance to open fire and is able to withstand very high temperatures. Therefore, such material refer to the NG group - non-combustible insulation. Very important quality for any housing!

Material not containing toxic substances.

Material not containing toxic substances.

Manufacturers try to minimize the possible emission of formaldehydes. Thus, basalt insulation with marking "Eco" or "Eurostandard" is environmentally friendly - not phenol formaldehyde, but safe acrylic resins are used as a binder. It is clear that the price of such products is much higher, but they really stand.

No matter how the opposite claims, the mice feel great in any mineral wool. So you need certain measures to prevent such "invasions".

No matter how the opposite claims, the mice feel great in any mineral wool. So you need certain measures to prevent such "invasions".

A significant lack of any mineral wat is that mice like to arrange their nests and moves in them. Moreover, the rodents of somehow absolutely not frightens the batter of the fibers - they feel great in warm and dryness. And if in the characteristics it is indicated that the material does not attract rodents - it is necessary to refer to this with a fairing fraction of skepticism.

Protect the heat-insulating layer is possible, for example, closing it available to the penetration of rodents of the metal grid with cells with a size of 2 ÷ 3 mm - it will not give up to the teeth of mice.

Mineral wool is used in different floor insulation schemes. The materials are low and medium density are suitable for laying between beams or lags. High-density plates can be used for warming on soil or overlap plate with a subsequent fill of the reinforced tie.

Ceramizite and use it for insulation

One of the most practical, reliable and durable, as well as environmentally friendly insulation is clay. This material is made from the refractory purified clay using its special firing technology.

Ceramzit of different fractions.

Ceramzit of different fractions.

This material has a lot of advantages:

  • Ceramzite does not contain toxic components, as it is a natural material.
  • Not bad thermal insulation indicators. At the same time, these qualities are not reduced throughout the entire operational period.
  • Low moisture absorption. Ceramzit does not swell and is not deformed.
  • Excellent sound insulation abilities. Moreover, the smaller the fraction of the material, the noise isolation above.
  • High vapor permeability.
  • Fire safety. Ceramzit mass not only does not ignore, but also prevents the spread of fire.
  • High frost resistance, resistance to temperature differences.
  • Resistance to biological influences. A mold is not formed on the ceramzite, since it does not have a nutrient medium for such microflora organisms. Ceramzit does not tolerate rodents - they just do not live in it, but cannot do in it.
  • Easy and variety of use options.

There is a clamzite and disadvantages, but they are much smaller than the advantages. And the main thing is that the thermal conductivity coefficient is still almost three times higher than that of polystyrene foam Il Mineral wool. That is, the layer of insulation will need more significant

Ceramzite is used in various schemes of floor insulation.

  • The first option is the easiest of all - this is the belling of the clamzite to the ground in the underground of the wooden floor. Before filling, a waterproofing material is laid on the ground base, which is understood and fixes on the walls to the height above the thickness of the backfill by 50 ÷ 100 mm.
  • Another option is to create a bulk of the layers of the necessary thickness of the GLC with the subsequent fill of the concrete reinforced screed
  • Another way to insulation by clay is his backfilling of it between the lags or the beams of overlapping on the draft floor:
Ceramzit Flood Between Chernov and Cut Stone

Ceramzit Flood Between Chernov and Cut Stone

If a fine-flow clay will be applied for filling, then the draft floor must be prepared. The gaps between the boards, if any, you can close the clay-limestone mass, which is also natural material. It will reliably hold the backbone between lags on the draft floor;

An alternative option is the flooring on the draft floor and parchment lags. Its canvases are styled by braziness by about 100 mm. Pergamine is also fixed on the wooden elements of the design of brackets driven by a stapler.

Floors warmed by dry clay.

Floors warmed by dry clay.

The next step between the lags is falling asleep clamzit mixture and is evenly distributed throughout the space. From above, the ceramisitis is sometimes stacked by a layer of vapor barrier film.

And finally, plywood or floorboards-floorboards are laid on the lags.

  • Another option of using clay is mixing it with a liquid cement-sandy solution. Concrete binds ground cleaner granules among themselves, which increases the strength of such a base.
Floor insulation ceramzitobetone.

Floor insulation ceramzitobetone.

Such material becomes particularly relevant when the floors are insulated on the ground - the leveling screed will be poured on top. True, it is used and when floors on the lags, filling with a solution all the space under the future flooring.

Since the insulation qualities of the ceramisit, still leave to desire the best, which requires very significant layers of frustration, it is often used in a complex with other thermal insulation materials - polystyrene foam or mineral wool. The calculation is made in advance which combination of layers of material will provide expected thermal insulation.

How to calculate the thickness of the insulation of the floor on the soil?

Nothing difficult if you use our calculator. In a special publication of the portal, several options are considered: using only ceramisite, only another insulation, and their integrated use. Calculator and detailed explanation for it - in publication "Floor insulation on the soil - the calculation of the thickness of thermal insulation" .

The main options for insulation of the floor of the first floor of a private house

Now more about how sexing insulation is carried out in a private house

Floor insulation

This approach is often practiced if the house is being built on a tape base. Ceramzite (independently or complex with another material) can be performed as a heater (independently or complex with another material), rigid insulation plates (extruded polystyrene foam) or high pay mineral wool blocks specifically designed for such purposes (this is negotiated in the passport characteristics of the Ministry of Service). In general, for any insulation in this scheme, one thing is close to the reinforced tie.

It can look like this:

Approximate Floor insulation scheme for soil

Approximate Floor insulation scheme for soil

Soil (pos. 1) is thoroughly tamped, while its surface is equalized to the maximum.

From above, sandfall is made (pos. 2), layerly, also with a thorough traam. Fasting thickness is usually not less than 100 mm (in the rammed form).

Further, it is shown an optional, but highly recommended layer of the shielded geotextile (pos. 3). It will become a big plus for the stability of the entire "cake" created, will serve to separate the sandy and gravel (rubbed) layer, which will improve the drainage capabilities of this design.

Above, also with a rubbing, a layer of crushed stone or large gravel (pos.4), on which the so-called "concrete preparation (pos. 5) is performed. This is a flooded layer of skinny concrete (enough valve strength M50). On this basis, it is much easier to perform further work, which will already directly swing insulation.

In concrete preparation, a layer of waterproofing is stacked (pos. 6) - the insulation must be secured from moisturizing from the soil. Applying for these purposes can rolled bitumen waterproofing - it will greatly fall on a sufficiently solid basis of concrete preparation.

Then the thermal insulation material of the desired thickness is stacked (pos. 7). About the calculation of thickness is described separately - the link has already been given. There are also possible combinations of insulating materials, so that thermal insulation has become full.

Further, the insulation is covered by another layer of vapor-permeable waterproofing material (pos. 8), as a polyethylene film may come, but very dense, with a thickness of at least 200 microns. The canvases are settled necessarily on 150 ÷ ​​200 mm and on the lines of seams are sealed with moisture-resistant scotch. Waterproofing should enter the walls to the height above the surface of the future floor. The purpose of this layer is to prevent the flow of water from a concrete solution when pouring a screed, that is, the creation of optimal conditions for pouring and ripening concrete.

The reinforcing grid, the cross section of the rod and the sizes of the cells depend on the intended degree of load on the floors depend on the intended degree of load on the floors. But this is general institutional issues, only indirectly related to the problems under consideration of insulation. The grid must be raised from the waterproofing layer so that it turns out to be about in the middle of the screed thickness.

Next, lighthouses are exhibited and the screed is filling. Its thickness is usually at least 70 mm. If desired, the pipes or heating cable of the "warm floor" can be activated in the same screed.

In the insulated semi-insulated floor, nothing prevents the heating contours of the heating floor system

After pouring, ripening and set of vintage strength, the resulting screed will serve as a universal base for any finish floor covering.

Insulated floor on the slab overlap

Such a scheme in a private house is infrequently used, but, nevertheless, it should be mentioned. Especially since it is very similar to the previous one, but much easier. If only because there is already a rigid reliable basis that does not require additional improvements.

Floor insulation scheme on the slab overlap

Floor insulation scheme on the slab overlap

What are the features here?

The basis is ready - this is the slab of the overlap (pos. 1) over the cold underground, as a rule - the void. It must be necessarily projected by the composition of deep penetration, and it will still be very useful to foresee the waterproofing layer (pos. 2). It is quite sufficiently coating isolation or even a dense polyethylene film.

Further, the selected insulating material of the required thickness is stacked (the calculation is the same as for the floor of the soil).

The next layer is again waterproofing (pos. 4), which will protect the insulation from the penetration of moisture from above and will provide an optimal water-cement ratio when the screed is frozen.

Well, above - reinforced screed (pos. 5), in which pipes or heating cable of the "warm floor can also be placed. And marks the entire design of the selected finish flooring (pos. 6).

Floor insulation for lags or overlap beams

But this option is occurring, perhaps, more often than others. And first of all, because this scheme is almost the only possible if the house rests on the pile or the foundation. But even for a ribbon foundation with a high base, it is quite applicable. "Heavy" materials such as cement, sand, gravel here are not used - the main thing becomes wood or materials based on it. Well, plus, of course, the insulation itself.

The principal scheme can be represented as follows:

Wood floor insulation scheme

Wood floor insulation scheme

On the beams of overlapping or lags (pos. 1), cranial bars are stuffed (pos. 2) or supporting boards. Lights will serve as the basis for the installation of rough floors (pos. 3). For this, the flooring can be used both boards not the highest variety and plywood or OSB sheet materials. The flooring can be solid, but more often the board is mounted with a vacuum - and for considerations of savings, and for better ventilation insulation.

Waterproofing is laid on the draft floor - windscreen (pos. 4). It is important - this layer should not prevent the free output of water vapors so that the moisture is delayed in the insulation. Sometimes, with frequent location of the board or when used as thermal insulation of stiff polystyrene foam plates, this layer does not fall at all - direct water from the bottom does not have to fear, and the wind exposure at a competently equipped base is unlikely to be so great that in the state of damage insulation.

Even, the layer of thermal insulation of the required thickness is placed (pos. 5). The illustration shows the laying in one layer, but usually it does not cost it - you need at least two. But it also for the better - plates or mats of the top layer overlap the joints of the lower, and the cold bridges almost does not remain.

Next - a prerequisite: a layer of reliable vaporizolation (pos. 6). The level of humidity in the premises during the cold season is always significantly higher than on the street. And in order not to penetrate the heater, seeking any loophole to the outgoing outward water pairs, it is necessary to put a reliable hermetic (without exaggeration) barrier.

And finally, the board or plywood (OSB) floor coating (pos. 7) is littered from above. In the diagram, again, simplification is allowed, but in fact it is recommended between a vapor insulating membrane and flooring to leave the ventilation clearance of about 20 ÷ 30 mm. It is easy to make the installation of additional registers for lagas - they will additionally fit the membrane, and will provide the desired clearance.

It is clear that the thickness of the insulation with such a scheme should be calculated in advance, since it in this case does not directly affect the choice of secting of sawn timber and lag. It will be necessary to carry out a particularly complex heat engineering calculation.

How to calculate the thickness of the warm floor insulation on the lags?

With the algorithm of conducting such calculations you will introduce a special article of the portal - "Wooden floor insulation - count the thickness" . It also places a convenient calculator calculator.

Another nuance. To protect the insulation from penetrating mice into it, you can also use a metal grid. It is mounted directly on the blackboard under the waterproofing layer. The edges of the mesh raise the wall above the thickness of the insulation 100 ÷ 150 mm. After laying the insulation, the grid is bend on its surface. After that, the insulation is close from above the same grid completely - it is shot to the lags of the brackets. Perhaps someone such measures will seem unnecessary, but it really helps if you do not leave loopholes.

Performing wood floor insulation on lags

This section of the article provides a step-by-step illustrated instruction on the insulation of floors of mineral wool.

The most important in the insulation of the wooden floor raised above the soil by 300 - 500 mm is the choice of optimal material and high-quality, according to all the rules, its laying

The number of blood production in the base is calculated depending on the area of ​​the underground space.

The number of blood production in the base is calculated depending on the area of ​​the underground space.

The first thing to be checked by deciding to insulate the similar floor is the presence of ventilation in the underground space. If produced in the base part of the foundation are absent, they need to be equipped. The lack of ventilation in this insulation of the floors will lead to the appearance in the underground space of dampness, to rotting wooden structural elements, to their amazing fungus.

The total area of ​​all products should be at least 1/400 of the ground floor area, but at the same time, not less than 0.85 m². The area of ​​one product is usually around 0.05 m². That is, it is easy to calculate the required amount and then consider their uniform accommodation on the base. At the same time, extreme produced should be located no further than 0.9 m from the corners of the foundation. And one more important condition is the symmetry of their placement, that is, product on one wall should correspond to the same on the opposite. Thus, their quantity is usually even.

These ventilation windows are recommended to immediately protect against the penetration of various livery with special lattices with a small grid.

However, we again deepened in general formulation issues - back to the insulation of the floor.

So, the insulation of the old wooden floor (if it is not about the installation of the new in construction) can be made in several ways:

  • Using the old board coating as a rough floor. Performing such an option is possible if the boards are in a normal state, that is, they do not have signs of rotting and are not moistened with the inner side. In addition, it must be borne in mind that the floors at the same time will rise by about 250 mm. If the ceilings indoors are high enough, then insulation on the old coating, without his disassembly, is seen possible. But, honestly, they resort to this path - infrequently.
  • The second option involves disassembling the board coating and laying the insulation under it. In this case, dismantled floorboards, if they are in a satisfactory condition, can then be returned to the place. If the boards are supposed to use the second time, then when dismantling, they are recommended to numbered.

Naturally, if a new floor is erected, then they begin "from scratch", that is, from the installation of rough floors - and then in order.

Below will be considered an insulation option in which the old floor is disassembly. Moreover, if the insulation is produced in an old house, the audit of the underground space, as well as the reliability of the ceiling beams - will never be superfluous.

The following materials will be required for work:

  • Insulating material. In this case, this is a mineral wool. As practice shows, and confirm the calculations, in private homes in most regions of Russia, it is recommended to lay this insulation thickness in at least 150, and even 200 mm. This, as a rule, implies a minimum of two-layer laying.
  • Boards or plywood for mounting a rough floor. The boards with a thickness of 10 and 150 mm wide will be quite enough.
  • Bar for counterbenches by cross section, for example, 30 × 50 mm. A larger size must correspond to the thickness of the lag or the ceiling beam.
  • Waterproofing vapor-permeable membrane.
  • Vapor insulation material.
  • Self-tapping screws and staples for a stapler.
Illustration Brief description of operations performed
So, by dismantling the boardwall, you can see the beams of overlapping and evaluate the possibilities of further work. If the beams overlap are in good condition, the first thing that needs to be done is to cover them with an antiseptic solution from all sides and give the coating well to dry.
Next, you can choose one option from two - to fix with the help of screws on the beams of the cranial bars, to which the black floor boards will be laid, or fasten the boards from the bottom of the overlap beams. Each options have their drawbacks. When fixing the cranial elements, the space for mounting the insulation will decrease.
Fastening the boards from the bottom of the ceiling beams, in principle, does not have drawbacks, except for the complexity of the performance of work. If the height from the soil to the beams is small, the installation will have to be produced lying on the back. The draft floor is necessary only to support the insulation, therefore, it is not necessary to make it solid or too often lay the boards. The distance between them can be even 200 ÷ 250 mm. And the boards can be used even non-edged. But antiseptic treatment is required in a nursing degree.
Another embodiment of the draft floor is to fix the transverse boards to the beams with a step of 700 ÷ 800 mm, and then fill on them a longitudinal coating coating. And between the longitudinal boards, you can also leave the gaps of 10 ÷ 15 mm. Clauses are necessary for proper ventilation of the insulation.
In some cases, for the draft floor, sheets of Plywood of OSB thickness of 10 mm are used. However, between sheets every 500 mm should be left for ventilation. Therefore, you will have to prepare pieces of plywood in a length of 500 ÷ 600 mm and a width equal to the distance between the centers of neighboring beams of overlapping (lags). As a rule, it is 600 mm - according to the traditional size of mineral wool insulation.
The next step on the draft floor is the vapor-permeable waterproofing-windproof. It is placed to protect the mineral wool of water entering (which is extremely unlikely in such conditions), as well as from the wind, which will penetrate underground through ventilation products. The membrane canvases must overeat overlapping beams. They are labeled with a 100 ÷ 150 mm. Skinching the scotch of these adhesives - optionally, the tightness is not required here.
The focus is necessary on the fixation of the membrane on the walls. The material should find them higher than the insulation thickness by 50 ÷ 70 mm. On wooden walls, the membrane is fixed with the help of a bracket, and on surfaces from another material - two-way construction tape. The insulation is still recommended to be isolated from possible contact with the walls.
Next, laying of insulating material. It is important to observe several nuances. The plates are most often stacked in two layers, and at the same time the upper must overlap the joints of the larger insulation. The standard width of the insulation plates is 600 mm, and it must be laid by the versius with the beams of overlapping, so the optimal width between the beams in the light is about 550 ÷ 570 mm (just on the axes - 600 mm, and due to the thickness of the beam, the lumen decreases somewhat) . However, such a step is not always observed, therefore, the plates often have to "retrofit" with additional fragments. Their joints should also overlap entire plates of the top layer.
From above the insulation, vapor insulation material is laid and fixed with brackets on the beams of overlapping. This layer is necessary to protect the insulation from the penetration of various evaporation on the side of the premises. The canvases also put on a 100 ÷ 150 mm (membranes are often even applied to the minimum strip width of such an adhesion). But here, the requirements for sealing - tough: the canvas are mandatory are sampled among themselves along the line of adhesive moisture-proof tape.
Then, if it is planned between a board coating and vaporizolation to create a ventilation gap (and this is strongly recommended), then the rails with a thickness of 25 ÷ 30 mm are fixed on the ends of the beams from above the vapor barrier. Some masters refuse this design element and consider it optional. But it is better not to neglect such ventilation - the condensate will not accumulate on the vaporizolation membrane.

With insulation, it is completed - and on top can be mounted a milking coating or flooring from plywood or OSB. But this is already - questions that go beyond our consideration.

Now, having a few options for the insulation schemes of floors with various materials, you can choose the most suitable method for a specific case. Adhering to the recommendations received and strictly following the technology, it is quite possible to independently make heat insulation of floors in your own home. At the same time, not only saving a decent amount into the family budget, but also gaining confidence that the work is made on conscience.

Finally, we suggest to see an interesting video. In it, a very amateur master produces independent insulation of the floors of its houses under construction. Honestly, there is something to learn. Furnace tile refractory you will find the answer by reference.

How to insulate the floor in a private house?

How to insulate the floor in a private house?

It happens that in the house, despite the excellent indicators of the heating system, it is still cool. This suggests that the room loses heat. To restore a comfortable stay in the house, you must take measures and engage in insulation of floors.

Features

Often in a wooden or brick house with thick floors there is a cold, coming from somewhere below. High-quality thermal insulation will not only cost the owner of the house is cheap, but will allow you to achieve maximum comfort in your home.

Pros of using systems for floor insulation in a private house:

  • The losses for the coolant will decrease significantly, therefore, cash savings will be noticeable;
  • If you warm the floor, then the area of ​​the premises will be heated evenly;
  • Improving comfort in previously cold rooms;
  • The lower part of the room will be much warmer;
  • There will be no dryness in the air. The newest technologies will delay the flow streams in the apartment;
  • There will be more free space, since the use of heating systems minimizes the number of radiators;
  • The process of heating occurs faster, the heat transfer increases;
  • Such systems have a long service life.

Types of insulation

All insulation can be divided into two categories: technological and using heat-insulating materials. Technical species are divided into electric floors and water heating. Electric floors include infrared film, heating mats and warm copper cables, and to water heating - a system of pipelines with a water heat carrier.

Insulation, as part of which heat-insulating materials are used, there are also several varieties:

Oriented chipboard (OSP)

It includes natural components (wood). It is performed by pressing with the use of chips (sawdust) and adhesive ingredients.

There are four varieties:

  • OSB-1. The moisture resistance of such a modification is rather low - less than 20%. This brand is intended for internal works and contains a minimum number of harmful substances in the composition of the adhesive;
  • OSB-2. It is characterized by a stronger design and is used to cover the elements of the dry room, because in a wet structure such material will be harmful to the human body;
  • OSB-3 and OSB-4. They are distinguished by the greatest resistance to humidity and high loads, but are the toxic materials in this line.

But, despite the danger of such a material, its use is quite often practiced not only in Russia, but also abroad.

Pros of the use of this material:

  • Saving funds. The cost of such products is rather low;
  • Easy installation. Such material is very easy to cut and secure. It is easy, so with its transportation there will be no special problems;
  • Long service life;
  • Widespread use. This material was used in the facing of the walls, in works with roof and in floor laying;
  • The right installation is a guarantee for resistance to a variety of hazards: corrosion, moisture, the emergence of microorganisms.

Mineral wool

According to regulatory documents, glass gamble, slag and stone wool refers to this material.

The fiber glass gambled is meager: thickness - from 5 to 15 microns, and length reaches only 50 mm. Such a structure allows it to be sufficiently strong and elastic. When working with this material you need to be extremely attentive - various dangerous situations may occur. So, for example, inhaling the glass dust, it is possible to damage the lungs, and when the glass yarns breakdown, the likelihood of them on the skin and eyes.

Fibers produced from slags, or slag, have such quality as residual acidity. This negatively affects metal surfaces in rawrooms. The material absorbs moisture well and is quite fragile. Not applicable for insulation of plastic and metal water pipes.

Stone wool differs from slagovat that it is not barbed, so it's much safer to work with such material. The most common variety is basalt wool, has the best characteristics, it does not contain mineral or binding components. It can be formed into rolls or sheets, fill in mats. When heated over a permissible temperature, it does not burn, but only melts.

Pros of using mineral wool:

  • Excellent noise insulation;
  • Small cost;
  • Long service life;
  • The ability to achieve the maximum effect during waterproofing of the main material;
  • Used with major repairs and erection of the structure.

Polystyrene foam

This material is performed using natural or carbon dioxide, as well as polystyrene and styrene copolymers. Most of the material is used when insulation and is the most popular in this area.

This product is divided into several types: the prestickable, presses and extruded. Prestse is fed by a multitude of inhomogeneous structures. Good absorbs moisture. Marking - PSB S-X, where X is the design density designation.

The press has hermetic pores, so it is considered reliable and high-quality thermal insulation material. It becomes dense and quite durable. Marked with PS letters.

Extruded, or PESEROPLEX, similar to the structure with pressed polystyrene foam, however, its pores are much smaller. Marking - EPPS (XPS-X). The second letter x denotes its density.

From the distinctive qualities of this material, the following positions can be distinguished:

  • Thermal conductivity. The best indicators of thermal conductivity are inferno. The more dense material, the higher this indicator. Therefore, the insulation of the penplex chooses the lion's share of consumers.
  • Parry permeability. This characteristic varies in the range of 0.019-0.015 kg / (m * h * pa), whereas in the foam it is almost equal to zero.
  • Moisture permeability. With full immersion in the water of the insulating insulation, absorption occurs in an amount of 4% of the material volume, and the extruded version is 0.4%.
  • The product having a medium or high density has a high strength characteristics.
  • The polystyrene is not destroyed when exposed to such substances such as soap, soda, fertilizer, lime, cement. Damage can be applied using turbidar, acetone, olifa, some alcohols, varnishes, as well as oil substances.
  • Ultraviolet rays for this material are harmful. This applies to absolutely all its modifications. It is initially lost its strength and elasticity, and then its complete destruction.
  • Noise insulation and sound absorption. To mucify the impact noise, the material must be laid in several layers. Noise waves neutralize it is not capable.
  • Reproduction of microorganisms. The polystyrene foam is resistant to the appearance of mold and fungal parasites. However, rodents and insects can pave their moves in it.
  • The open air for this material is destructive, as the oxidation processes will begin to occur here, which are usually accompanied by the release of toluene, benzene and other harmful substances for the living organism.
  • Fire resistance. This type of material refers to flammable. In addition to the release of caustic smoke, the insulation highlights toxins: a sinyl acid, hydrogen bromide and phosgene.
  • Lifetime. This material is durable. When complying with the rules of installation, it can serve over 30 years.

Advantages of the product when applied:

  • Low thermal conductivity. For example: if you use a 120 mm thick polystyrene foam, its thermal conductivity characteristics will correspond to the brick thickness of 210 cm or 45 cm wood;
  • Small weight of the product. Such material is convenient to use, since low weight allows you to mount and transport it without assistance;
  • Waterproof. This material can be used as a waterproofing component, because it is resistant to moisture;
  • Resistance to deformation loads. The product is distinguished by excellent compression strength parameters. This allows it to be used for insulation and waterproofing under the tie to the floor;
  • Resistance to temperature jumps. Products made of polystyrene foams are distinguished by cold and high temperatures;
  • Simple installation. Install, process edges or cropping a part of the material will be able to establish a regular user, it is enough to have a knife at hand;
  • Low cost and reduction of heat costs.

Styrofoam

Such a heater is a foam structure, which contains air (98%) and polystyrene (2%).

In the process of thermal insulation, several polystyrene varieties are considered suitable: polystyrene, polyurethane, polyvinyl chloride and polyethylene.

For household needs, polystyrene foam is most often used.

In shape and structure, it can be divided into:

  • Sheet. Refers to universal types of insulation, because it can be used for heat insulation of walls, ceilings and floors. The dimensions of the foam of such modification can be diverse;
  • In the form of balls. Used as a backfill in different cavities;
  • Liquid. Another name of this insulation is foamizole. The appointment is the same as the previous variety of foams.

The advantages of its use are quite a lot: versatility, simplicity of installation, light weight, low cost, hypoallergenicity and long service life.

Isolon

It is one of the latest construction development, allowing to preserve the comfort and heat of a homely hearth.

Two main groups of such material are distinguished: PPE isolon and NPE isolon. PPE isolon is crosslinked polyethylene foam with a transverse structure, and the PPE is an extruded version that differs from the previous one by its molecular physics and a nonstrusive structure.

The advantages of such a material:

  • High quality heat insulation. For comparison: the characteristics of the heat-insulating material with a thickness of 1 cm are equal to 1 layer of brick masonry, which allows you to further save free space;
  • The presence of waterproofing properties;
  • Protects against moisture and steam;
  • High indicators of noise absorption;
  • Strength;
  • Resistance to chemical reagents;
  • This is an environmentally friendly material;
  • Long service life - over 100 years;
  • The ability to reuse;
  • Elasticity and minor weight characteristics.

The disadvantages of using this material should be attributed to the high cost, the need to comply with the installation technology, compliance with storage requirements and careful transportation.

Penophol

This product is a rolled material from polyethylene with a foil layer. The effect of the foam is based on obstacles to convection due to polyethylene foam and increasing parameters (up to 97%) of thermal reflection due to the presence of foil.

The varieties of this product can be distinguished by marking, which is indicated by letters:

  • A. Such a modification of the insulation is endowed with an aluminum foil surface only on one side. It can be applied along with other types of material.
  • B. This variant of the foam is used as an independent material for insulation. It has a foil layer in its structure covering both surfaces of the product.
  • C. This category is easy to install, since it is equipped with a moisture-resistant self-adhesive surface on one side and a foil coating on the other.
  • ALP. This species additionally has a polyethylene film on the foil surface.
  • R and M. The product is distinguished by the embossed surface with the applied foil layers for one side.
  • Super Net. It is used for thermal insulation of communications.
  • AIR. It is used when creating structures on the air vent.

Positive aspects of using foam:

  • Ease;
  • Simple installation;
  • This is an environmentally friendly material;
  • Fire resistance;
  • Low vapor permeability;
  • Low value of the material.

To disadvantages of insulation, the foam can be specified, since any insignificant pressure is capable of damageing the material, poor adhesion and high electrical conductivity (you need to be particularly attentive with the electrical wiring, since aluminum is well conducted by electric current).

Ceramzit

This type of material is made in granules with a diameter of up to 5 cm. The discarded elements are crushed. Thus, there are three varieties of clay: granules, sand and small gravel.

Advantages:

  • Environmental purity;
  • Strength and durability;
  • Resistance to temperature differences;
  • Fire resistance;
  • Excellent quality thermal insulation and noise absorption;
  • Affordable price.

The disadvantages should include its quantity that is required for good thermal insulation. Such material should be in a layer of at least 50 cm.

It is possible to use clamzite in the insulation of the floors, made using a concrete screed or boards on the soil, as well as on top of concrete. This stuff has been applied in the insulation of the underground of the private house, as a supplement to waterproofing, in the insulation of the floor on the loggia and the first floors with unheated basements.

Tips for choosing

The right choice of material for insulation of floors in the country house should always be based on the product specifications. They can be found on the package with the product.

Below are the parameters for which it is better to pay attention to the purchase of material:

  • Felority coefficient. Denoted by the letter G. The most non-combustible material has marking G1. It flammives only with direct contact with fire.
  • Water absorption coefficient. Unit of measurement - percentage. The lower this indicator, the less moisture it can absorb. Consequently, the material will be less collapsed and will preserve its properties better.
  • Coefficient of thermal conductivity. This indicator is responsible for the thermal insulation of the premises. What it is lower, the warmer will be indoors.
  • Density. Indicates how much harder is the floor constructive. The more this indicator, the stronger should be overlap and draft floor.
  • If the owner of the house plans not to be extremely embarrassed on the insulation of the floors, then you can use the budget option. For concrete floor, extruded polystyrene foam is perfect. It is compatible with a warm water floor system.
  • Ceramzit can be used under the tie of the floor. It will serve long and can be used in multi-storey buildings.

There are a number of non-combustible insulation, which received decent attention among the domestic buyer. The following stamps are particularly popular: Isover, URSA, Knauf Insulation, Termolife.

Materials based on flax, basalt, coconut and jute can be attributed to non-combustible insulation.

Often, man, making the major repairs of a private house, thinks about the insulation of the veranda. But here you can also save on finance. For this you can use foam and mineral wool. However, the polyfoam has a property when combustion is distinguished to allocate the substance dangerous to life - you should not forget about it.

In order for the room to be truly warm, do not forget about the insulation of the church of the attic. For wooden, a bulk version of the insulation is suitable - it will be able to "breathe" the roof. Heavy options in the form of plates can use the home owners if the overlap is made of concrete, and roll insulation can be used for environmentally friendly materials.

Old houses that were built at the beginning of the 20th century are distinguished by the fact that they are present in them. It is also possible to insulate it, but before that it is necessary to fit it well and tackle. Next - by technology: waterproofing in several layers, insulation, clean floor. The insulation can use foamed polyethylene.

Thermal insulation of a wooden base

The wood insulation of the tree is usually carried out with the help of mineral wool on lags. Old wooden floor is cleaned. After examining the boards, it is necessary to remove the old paint, stick and treat them with antiseptic substances. After they succeed, you need to put them horizontally.

Garbage and dust from a rough base must be removed. Rocking lags are required to replace, and the resulting design needs to be treated with an antiseptic, let it dry. When laying dense polyethylene joints, it is advisable to exeterate the construction scotch. Waterproofing to secure lags with a stapler.

Then it is necessary to cut mineral wool and put it tight between the lag. Next, it should be provided for a layer of vapor barrier over the entire structure, connect the joints with scotch and secure the stapler.

The next stage will be the laying of old boards and installation of the plinth. Speakers of waterproofing need to trim and then paint the coating.

Warming with expanded polystyrene should be started with removal of finishing. Then it is necessary to inspect the base and check its level. In case of exceeding the drop of 1.5 cm heights, the basement meter must be aligned.

Then it will be necessary to remove garbage and dust, as well as pour the cement screed of the desired height, wait for drying.

Dispressing polystyrene foam, stack tight polyethylene. We connect the edges of the canvas with scotch, we start on the walls and fix it.

Installation of the insulation must be performed in two layers. The first layer must be laid with the dressing of vertical joints. The second - in the same way, only its location should be strictly over the seam of the first layer;

We set the reinforcing mesh with a height of 3 cm. Cooking a mixture for a screed. Concreting the bases by parts, smoothing the sakes by Kelma and checking the level, expect drying (this process usually takes a whole month). Perform a finishing finish.

Warming concrete

Minus concrete floor is bad thermal insulation. Therefore, in this case, it is necessary to use the insulation.

Here are some ways to insulate the concrete floor in the country of their own hands:

  • The concrete floor is covered with clay, and the screed is poured over it;
  • The mixture for creating a screed is complemented by fine-meal clay or crushed foam;
  • On top of the flooded screed, you can put another layer of insulation. To do this, mount bars, and from the inside, perform a layer of selected material for insulation. Then lay a layer of vaporizolation, and close on top to boards or plywood;
  • Installation of any type of warm floor.

In order to make a warm floor in a country house, it is best to use the services of a specialist. But for the sake of saving money, people spend their time and strength.

Below is a brief instruction on the arrangement of a warm floor in a private house:

  • To begin with, prepare a place under the collector. It is necessary to control the temperature regime in the room.
  • Preparation of rubberoid and other insulation materials - they will be required for the waterproofing layer. First of all, they need to roll them on the surface of the base. Stacking to produce twisted 10 cm.

Shakes glued. To do this, you can use the effect of high temperature or tape.

  • Preparing layer of isolation. Usually used foam with high density. The layer should turn out at least 5 cm thick.
  • The next stage is vaporizolation. A dense polyethylene film may well come up. Laying is made by 10 cm, after which a gluing scotch is performed.
  • The resulting "pie" contains laying of a reflective film to refer up the flow of thermal energy. It contains the reinforcement grid with cells of 150x150 mm.
  • Laying the circuits of heating pipes with a maximum length of 80 m is performed on top of the reinforcement grid.
  • Fastening pipes with a coolant must be performed using clips to the grid.
  • Bay of the finish tie. Additionally, you can use a plasticizer - it will not allow cracking of the screed when heated.
  • The final stage is laying on the perimeter of the placement of the damper tape and the finish coating.

Errors

Below are some points that cannot be allowed in the process of insulation of the floors:

  • It is impossible to insulate the room partially, if they require major repairs;
  • If there is an ordinary counter, the use of infrared or water floors is unacceptable;
  • Cheap materials in most cases are harmful to health. They can cause not only allergies in humans, but also lead to undesirable consequences;
  • In the process of installing a warm floor system during the pouring, the screed cannot be kept off the heating contours empty. The heating should be absent;
  • It is prohibited to use foamed polystyrene and foam in filling the space between beams in a wooden structure, which consists of several floors. When attaching sheets, they are poorly isolated, therefore, available for oxygen. Therefore, in the process of ignition, the fire can easily penetrate inside.

Errors when insulating flooring in a private house can be viewed in the following video.

In domestic climatic conditions, the need for the insulation of residential buildings does not cause any doubt. Owners of private houses have to solve this problem on their own. Wooden boards, of which, in most cases, floors are manufactured in country households, are deformed over time, and enlightements appear in a tightly shot down.

It is difficult to imagine, but through these cracks during the cold season it can leave up to thirty percent of thermal energy. As a result, heating costs increase sharply, the comfort of living in the winter period is reduced. To prevent these consequences, it is necessary to warm the floors qualitatively.

Wood floor insulation
The list of materials for the insulation of the floor is quite wide

Wood floor insulation techniques

The heat insulation procedure of the wooden floor should be foreseen at the design and construction stage of the house, and then the minimum labor and financial resources will be required. If it is necessary to perform this manipulation, when the overlap is already ready, the performance of work is significantly complicated. In this case, it is possible to work correctly and insulate the floor can be on top, right on old coating, or with its partial dismantling. There is also an option of insulation of flooring from the bottom from the basement.

Floor insulation
In this case, it is more convenient to warm the floor from the basement side

Heat insulation is made from above, if there is a low basement in the house. If at the same time the flooring is dismantled, only lags are left. The procedure is characterized by a lot of labor intensity. In the event that the basement of sufficient depth, laying the insulating material can be made from below. It is much easier and faster, since in the process of performing work does not have to dismantle and disassemble the flooring if it is in good condition.

The better the floors in the private house

Floor insulation in a private house do it yourself quite real. This uses a variety of heat insulating materials. Which one is better, is determined after analyzing their performance and specific conditions in which they will be operated. The insulated floor significantly increases the comfort of living in the house at negative ambient temperatures and reduces heating costs.

Floor insulation Eco-friendly
Equata - one of the options of insulation for wood floor

The foam and expanded foam and polystyrene are widely used, the use of glass gambles and mineral wool has its own characteristics. The most simple and lowest method of insulation of the surface of the wooden floor with clay or with wood sawdust. Not bad performance characteristics are the so-called dry screed.

Advantages and disadvantages of foam and expanded polystyrene

Many people know that you can warm the floor with polyfoam. Polystyrene foam for sex is also popular with professional builders and home masters. Polyfoam and expanded polystyrene, due to their excellent operational qualities, were widely used as insulating materials. With the exception of minor differences, their technical characteristics are comparable to each other. The use of these thermal insulation materials carries the following advantages:

  • low cost;
  • low thermal conductivity;
  • a small mass;
  • a wide range of use;
  • long service life;
  • resistance to the effects of pathogenic microflora;
  • Install installation.
Floor insulation Foam
Quite often the floor insulate foam

In addition to the above advantages, these materials have operational disadvantages. Their list is also quite impressive, the following negative qualities can be noted:

  • distinguished harmful substances with ignition;
  • prevent the passage of water vapor;
  • afraid of exposure to direct sunlight;
  • attractive for rodents;
  • are destroyed upon contact with solvents;
  • Have low mechanical strength.

Characteristics of the "dry screed" for insulation of floors

The so-called "dry screed", which is made from plaster fiber, is perfect for the thermal insulation of the wooden floor of the private house. The use of this composition involves the following positive parties:

  • excellent thermal insulation;
  • fire safety;
  • ease of laying;
  • compatibility with all finishing coatings;
  • a small thickness;
  • Good characteristics of noise absorption.
Warming "dry tie"
The process of laying a "dry screed" for floor insulation

At the same time, since we will warm the floor with a dry mixture of factory manufacture, it is necessary to take into account its high consumption: the processing of one square meter of the surface requires twenty kilograms of the mixture. In addition, when water penetration, the geometric dimensions of the dry screed change, which can lead to a deterioration of the final coating.

The possibility of using mineral wool

Mineral wool is widely used to provide heat insulation of wooden floors. The material is made in the form of plates that are easy to put on the floor with their own hands.

Floor insulation Minvata
Mineral wool is well suited for floor insulation

Mineral wool has many positive properties. The material is distinguished by magnificent noise absorbing and insulating qualities, fire safety, prevents the multiplication of pathogenic microflora, racks to the effects of aggressive chemical environments.

However, when water enters the water, the deformation and partial loss of heat insulating qualities occurs. In addition, mineral wool has low mechanical strength and does not apply to environmentally friendly materials.

Features of glass gaming

Glasswater is similar in its characteristics with mineral wool. A feature of its application is that when performing work, it is necessary to carefully ensure that it does not get into organs of vision or skin cover.

Floor insulation glass
Glasswater - Common Wood Floor insulation

The production process is complicated by the need to use by an employee of individual means of protection. The negative quality of this material is its significant shrinkage over time, as a result, with incorrect laying there is a disruption of thermal insulation.

Pros and disadvantages of using clay

Ceramzit is made on clay-based foamed and burned granules of porous structure. The big plus of this material is low cost, environmental purity, small weight and long service life, which is about fifty years. Ceramzite has excellent insulating and insulating qualities. Thus, the thermal insulation of the surface of the wooden floor with a clamzite does not break the shape in the family budget.

Floor insulation ceramzit
Floor insulation with clay - simple and inexpensive

Its use of its use can be considered the need to perform a considerable layer of frustration, otherwise wooden floors will remain cold, especially with sharply negative ambient temperatures. In addition, it absorbs moisture well, although not losing insulation properties.

Sawdust - the cheapest material

The cheapest value of the material is finely crushed wood sawdust. They do not represent any danger to human health, the technology of performance of work is extremely simple: sawdusts are covered between the draft and the floor-coated floor. Before use, this material must be carefully drained at least twelve months, otherwise it will quickly come into disrepair. Waste cut freshly edged trees can not be immediately applied.

Floor insulation sawdust
Apparently, sawdust is the most budget version of the floor insulation.

An increase or decrease in the layer thickness is regulated by the heat insulation level. In the northern regions with a very cold climate, you have to pour a very thick layer. It is necessary to take into account the attractiveness of this material for rodents and to release them to add to the composition of the two parts of the harated lime in a dry form. The disadvantage of wood sawdust is the emergence of rotation processes in them during wetting.

Modern selection - Clear and Penophol

Undoubted operational advantages are characterized by the use of such modern materials as insulation such as isolon and foam. Cellon is a foam polyethylene coated foam layer and has excellent sound-insulating qualities with a very small thickness. The material does not support combustion, prevents the development of pathogenic microflora and corrosion processes, the two-chaser layer is comparable by soundproofing and heat-saving properties with masonry in one brick.

The foam produced in the form of rolls consists of several layers of insulation, on top of which is a reflective foil. It serves as a screen that prevents high losses of thermal energy.

When using foam, it is not necessary to carry out additional waterproofing work or the archoland of a vapor barrier layer.

The easiest way is to lay a double floor

The easiest way to perform insulation is to provide at the stage of building a house laying double floor, which is a draft and finishing coating. Such a system of insulation should be used in a room with high ceilings, as you have to occupy useful space.

Building technology provides for the laying of the Lag, on which the draft floor will be strengthened. The coating can be made from wooden boards, chipboard, OSB or other similar materials, it is only important that the structural elements are tightly fit to each other without forming gaps.

Double floor
Double floor arrangement - reliable insulation option

In the surface of the draft floor between the guides, insulating material is stacked. At the same time, it should not be used in its quality sand at high natural humidity, since in this case the formation of condensation is possible. On top of the insulation, a blank coating of wooden boards with a thickness of about five centimeters is mounted. A new coating will have to paint, as described in the article "How to paint in the house wooden floors of paint or covered with your own hands."

Of course, the old floor can be insulated in the same way, however, it should be taken into account a decrease in the relative height of the ceiling.

The most correct insulation of the floor - on lags

When building a new home or dismantling the coating, the most proper insulation of the floor is the method of performing lags. In this case, the insulation is located between the lags, which serve as the basis for the first floor. Depending on the construction of the building, the basis for the installation of lag and the insulation can serve as a rough floor, made on its own lags, as well as concrete coating or even ground. In the latter case, it is useful to equip a clay castle to protect against moisture layer of about 5-10 cm.

Warming between lagami
Dense insulation can be held between lags on ordinary nails

In the technology under consideration, the height of the lag and the distance between them should correspond to the height of the insulation and its width. Before mounting the floor covering over the insulation, the vapor insulation layer from the waterproof film fixed on the lags should be equipped. The junctions of the film can be fixed with scotch.

How to insulate the floors do it yourself from the bottom, without removing the old floor

If a private house has a deep cold basement, the most correct way will perform insulation of the floor from the bottom, without removing the old coating. It does not need to choose a material that can withstand heavy furniture weights and other mechanical loads. In this case, the defense will be performed not only the pure surface, but also the overlap as a whole, and the overlapping dew point will move outward, and the coating will not be rotated.

When performing such a task, some difficulties consist in rapid fatigue when working with constantly raised hands. There are also restrictions on the types of heat insulating material and the need for its fastening with increased reliability.

Schematically, the insulation is performed as follows:

  • Initially, the waterproofing layer is shown;
  • Then there is a heat insulator;
  • on top of it isolation from water vapor;
  • Next, the overlap is performed, ensuring the hold of the heat insulation of the floor.
Foam insulation from below
Polyfoam can be fixed from bottom to nails with gaskets and mounting foam

Adhering to such technology when performing work with your own hands, you can get the most comfortable temperature regime in the residential premises of the house. The heat insulator must be a small weight, as it will have a permanent load on the attachments, the bulk materials in this case are not suitable.

Floor insulation in a wooden house from the inside by foam or glass wool

Good results give insulation from the inside by foam or glass wool. These materials are distinguished by low weight and remarkable heat insulating qualities. At first, waterproofing is fixed to the lower surface of the overlap with a stapler. Next, it is possible to lay insulation plates in such a way that they retain during installation due to the friction force. For this, their width should be a little more distance between the lags. When working with glass, it is necessary to use individual means of protecting the respiration organs, vision and skin.

Penoplex for floor insulation
Penoplex - reliable wood floor insulation

On top of the insulation, a vapor barrier film is superimposed, which is attached to lags using brackets and stapler. Next, the lags are mounted a frame that holds the insulation. It can be made of any material that will suit you in appearance and durability. Between the holding elements are allowed, intervals are allowed through which the insulation will not fall out.

Step-by-step manual insulation of wooden floor polyurethane

Currently, the widespread the heat insulation of the wooden floor is polyurethane. To perform this work, it is necessary to pre-prepare the basis for which the eco-board will be applied, and spray the composition on the lower surface of the overlap. Step-by-step instruction looks like this:

  • The coating is cleaned of contamination and is carefully degreased;
  • It is dried to the base to humidity of no more than five percent;
  • High pressure installation is connected by hoses to tanks with mixture components;
  • Polyurethane foam is a uniform layer spreads over the floor surface;
  • The drying time of the coating occurs within two days from the moment of applying.
Insulation polyurethane foam
It is quite realistic to insulate the wooden floors below the polyurethane foam

High pressure equipment by which polyurethane foam is sprayed, it is very expensive. Acquire it for the arrangement of thermal insulation in a private house is irrational and better to take this equipment for rent.

Dear reader! Your comments, offers or review will serve as a reward author of the material. Thanks for attention!

The next video will tell you how to insulate the floor originally, quickly, simple and inexpensive.

Floor insulation in a private house is required: if this is not done, a significant part of the heat will go through this part of the structure. The surface will always be cold in winter, you will have to go to the shoes that is not very comfortable. Work is easy to carry out if you follow simple recommendations and use quality heat-insulating materials.

How to insulate the floor in a private house under linoleum

What and how to insulate the floor in a private house

Even before the start of work, it is necessary to align the surface, without this, the linoleum will not fall as conceived. Methods are many, it all depends on the floor manufacture material. As for insulation, it is best to use one of two options:

  1. Extruded polystyrene foam. Unlike conventional foam plastic, it has high density and does not bend under the weight of man or furniture. Sheets can have a thickness of 20 to 50 mm, pick up better stove stoves to not raise the level. There are grooves, at the expense of which the sheets are easy to dock, the edges are cut off with a metal with a metal. For reliability, the joints are sampled by foil scotch.
  2. Insulation of foamed polyethylene with reflective surface. Its main advantage is a small thickness that does not take space, heat is kept due to the reflective coating, which should be sent to the room. The roll simply spreads, is cut down in length and fixed, the seams need to be sealed with a special ribbon so that the heat does not go through the joints.

Important!

If the floor is very cold, you can combine both options to ensure the maximum effect.

If a linoleum with a substrate, it can be reduced over the thermal insulating layer. If the coating without lining, the special material is laid out of the tube or jute, it is not necessary to carry out the floor covering without it.

Floor insulation options over a cold basement

What and how to insulate the floor in a private house

It all depends on the overlap material, it can be a concrete plate or wooden lags. Based on this, the insulation is selected, a lot of species and each have their own characteristics that need to be considered when choosing:

  1. Sawdust or clay. A bulk version for wooden structures or concrete bases with lags laid. It will cost the cheapest, but also the indicators of thermal insulation will be lower than that of other varieties. In addition, sawdust needs to be treated with a special composition to protect against fire.
  2. Mineral wool. It may be soft mats that are filled by the space between lags, or rigid plates, they are cut in size and fill the entire space for high-quality insulation. It is better to use the second option: the plates are high thermal insulation rates, over time they do not fit and do not lose their characteristics. Choose in thickness: if you need to fill the space with a height of 10 cm, it is better to put 2 layers of 5 cm with displacement of the joints, so the effect will be better.
  3. Equata. A modern solution that is flounded cellulose. It is applied with a special installation and fills all empties without giving cold to penetrate the slots. Equata is not afraid of dampness, when wetting, thermal insulation characteristics are not reduced, it does not affect the fungus and does not damage the rodents, it does not sit down with time. The application will need equipment, and this is the main disadvantage of this decision.
  4. Styrofoam. Inexpensive view, which is often used and when insulation of the floor. Since the sheets will fit between the lags and close the boards, it is possible to acquire the cheapest type of low density, it does not matter much, since it will not be loaded on it. When laying it is important to measure everything as accurate as possible so that there is no cracks between the tree and the foam, through which the cold penetrates. Empty and other problem areas are filled with mounting foam.
  5. Granulated expanded polystyrene. Looks like a foam, but it's not sold in sheets, but an ominge, so they can be filled with all empties and do not have to close the gaps. Another advantage of this solution is low cost, the material is not enough, but at the same time the properties are preferable to sawdust or clay. It is chosen by those who need to minimize the load on the overlap, as the polystyrene foam is very light.

Important!

Sometimes combine various types of insulation, it all depends on the situation and the design of the overlap between the basement and the rooms.

It is necessary to choose a suitable solution based on the characteristics of the structure and budget, since the price may vary very much. It is also necessary to take into account the features of the climate: the colder the winter, the better it is to isolate the base, especially if the cold basement should be reached.

How to warm up the floor under the board

What and how to insulate the floor in a private house

If the floor covering already lies and do not want to raise it, and the overlap must be insulated, one of two technologies can be used. The main thing is to have access to the surface from the basement or basement. The first variety is liquid polyurethane foam. It will no longer, the technology has such features:

  1. The composition is applied using an installation that foams it and evenly distributes. The layer can be done any, which is very convenient. But only a specialist in special equipment can work, so it will have to pay for its services.
  2. After drying, a durable coating is formed without voids, which is well kept warm and does not destroy over time if the sun's rays do not fall on it. The composition is perfectly held on all grounds, they should not be prepared.

For insulation from the bottom side, extruded polystyrene foam is also suitable. Dense sheets are not destroyed under the influence of dampness and temperature drops, so they can be used in this case. It is necessary to comply with several recommendations during the work:

  1. Conduct measurements and cut pieces of the desired size in advance. Buy a special glue-foam, which is applied with a gun, it will increase the quality of insulation and will significantly speed up the process.
  2. Apply a small amount of glue around the perimeter and in the middle, then press the item and keep for a few seconds so that it is fixed. It should be actually acting so as not to get foam - wash it off from clothes and hands is not easy.
  3. The slots around the perimeter and emptiness fill in the same glue or buy a mounting foam - it will cost cheaper if you need to fill a lot of joints.
What and how to insulate the floor in a private house

Tip!

If the foam still got into his arms or clothes, it can be laundered to wash the gun or buy a drug "Dimeksid" in the pharmacy, it removes even the dried composition.

If during construction to insulate the foundation from the inside, and the space under the house flooded with sand, the protection from the cold will be much better. The preferred option is the insulation of the floor during the construction of the house or with its overhaul when there is good access to the surface.

How the insulation of the floor under the screed from the rest

If there is a screed in the room, you need to comply with technology during work. In the process there is nothing complicated, but you need to do everything according to the instructions and do not miss any important point:

What and how to insulate the floor in a private house
  1. Prepare the basis: if it is wooden flooring, it is necessary to close it with a waterproofing film. Other surfaces to align, if they are in poor condition, pour a solid black screed or make it places where it is required.
  2. Place extruded polystyrene foam or foam density from 35 kg per cubic meter. It should be treated so that there is no cracks, in this plan it is more convenient for extruded plates with grooves, they are much easier to go. The slots near the walls can be filled with the mounting foam so that there is no significant voids.
  3. On top, the vapor insulation material with the adhesive on the walls, so that there was a stock on the pouring screed. The joints are sampled with ribbon, there should be no breaks.
  4. To strengthen the floor and uniform load distribution, the grid is placed with a cell 5x5 cm. It is simply unwound and laid out by rows, you can not connect them, but to tie a special wire.
  5. Scial to pour as usual, there are no differences from the situation when the floor is made without the heat insulating layer.

If you take the floor right on the soil, you need to make a pillow. First, pour out 10 cm rubble and dissolve, and then make a layer of sand with a thickness of 5 to 10 cm, after which it is good to moisten it and tamper by manually or using the installation.

How step by step insulation the wooden floor: specialist advice

What and how to insulate the floor in a private house

To comply with technology, it is worth disassembling a step-by-step process description, it does not differ in difficulty, but requires a clear compliance to ensure the best effect. Professionals perform work on thermal insulation so:

  1. Prepare the basis, first you need to make a draft floor if it is not. Use the unedged board, you can even navigate with the slits, it does not matter much.
  2. Then it should be sealing the waterproofing, and, to lay it so as to close and lags. For fixing the material in niches, the easiest to use the construction stapler. At the joints of making an adhesive at least 10 cm and schohal the connections with scotch.
  3. Stop mineral wool in the niche as close as possible. Soft mats cut more by 2-3 cm to push them. Hard stoves cut exactly, put so that there is no emptiness.
  4. On top to lay a vapor insulation membrane and secure the stapler, not forgetting to sample connections.

For your information!

It is the mineral wool that is considered the most suitable insulation for wooden structures.

Heat the floor in a wooden house is easy if you follow the recommendations from the review. First you need to choose the optimal insulation, and then lay it on technology. Work is best done at the construction stage or overhaul.

So that the house is comfortable and cozy, it needs to be thoroughly insulated. Floors, along with walls, ceiling, window and doorways, are a source of large heat loss. This problem is particularly relevant in the buildings, which are directly on the ground, without the basement. In this case, even intensive housing will not help. The presence of a cold basement under the building will not be salvation.

The insulation of the floor in a private house, spent competently, with their own hands, will save homeowner from discomfort, will save on the services of professional masters and reduce heating costs.

Heat insulating materials: Benefits and Disadvantages

Most often owners of private houses insulate floors with clay, foam or mineral wool. The popularity of these materials is explained not only by their completely democratic value, but also by other numerous advantages.

Today, the building materials market offers a modern insulation Penoplex, which also has many advantages, but characterized by a high price.

Ceramzit

This is a granular material on a clay basis. Thanks to its fine-resistant structure, it is very light. His main thing is to accumulate moisture, he does not lose its insulating properties. The undoubted pluses of the ceramisite include the following:

  • good thermal conductivity;
  • resistance to temperature differences;
  • fire resistance;
  • strength;
  • durability (prolongs the life of wooden floors to 50 years);
  • environmental friendliness;
  • Easy installation.

It does not require serious vapor and waterproofing for laying such a heat insulator.

The disadvantage is the thermal insulation layer of the ceramisite should be at least 10 cm, and preferably even more than 50 cm. Otherwise, the degree of insulation will be insufficient.

Styrofoam

This is one of the most popular thermal insulators used in private construction. High heat and sound insulation are the main advantages of this material. Polyfoam is obtained from various raw materials, so it may differ density. The greater this indicator, the lower the level of thermal insulation and higher resistance to mechanical loads.

For the floor, the material is chosen with a low density, as it is protected from above the draft and stemty coating. Polyfoam is durable. Various microorganisms in it will not appear. Floor insulation in a private house foam - the process is simple.

The disadvantages of foam include high fire hazard, as a result of burning, it exudes the poisonous smoke, and the "love" of rodents (they cause a significant harm to insulation).

Mineral wool

Over the past decades, this material has become a traditional insulation of walls, ceilings, floors. We produce it in the form of plates, mats or rolls. With the right installation of Minvata will serve at least 30 years. It is not afraid of temperature differences, completely fireproof. Low thermal conductivity, good sound insulation, ease of installation - the main advantages of mineral wool.

Disadvantage - vapor permeability. The prerequisite for the installation of this insulation is high-quality waterproofing. Otherwise, with the time of Minvat, it is impregnated with condensate, accumulate moisture and quickly will lose its heat insulating properties.

Also, when using this material, you need to use protection against rodents that do not mind settle in it.

Penoplex.

The demand for this material on the Russian market of building materials is great. Penoplex is a foamed polystyrene produced by priming a general-purpose polystyrene. In the process of manufacture, air hermetic cells are formed in it, after pouring, the material acquires a homogeneous structure.

It is distinguished by durability, strength, simplicity of installation. Such quality as frost resistance allows you to use it in the most severe climatic conditions. Penoplex has a low thermal conductivity: 5 cm insulation replace brick laying with a thickness of 1.5 m. Its advantages include a low level of moisture absorption and vapor permeability.

Disadvantages: High temperatures are afraid (melting), big value, "love" rodents.

Solving the question of how to insulate the floor in a private house, which insulation to do this, specialists are recommended to focus on the basic parameters of materials present on the labels, in the package characteristics:

  1. Coefficient coefficient (M1 marking - the material does not burn without direct fire);
  2. The coefficient of water absorption (indicated in percent, the lower, the less water absorbs the insulation and better retains insulating quality);
  3. The coefficient of thermal conductivity (the material with a lower indicator is better isolates the floor);
  4. The density indicator will indicate how much heat-insulator weights the floor design (the higher this coefficient, the more durable there should be rough floors and overlap).

Warming technology

To lay the heat insulator, it is necessary to prepare the following materials: insulation in the required quantity, film (density of at least 200 microns), cement, sand, water, beam, reinforcing grid.

The process of insulation of foam plastic consists of several stages.

Training

Before that foam, it is necessary to remove the excess soil to a thickness of 10-15 cm or, on the contrary, make a submissance from sand and rubble to the same below the alleged floor.

Surface must be aligned.

Waterproofing layer

A layer of waterproofing from a dense oil was created: it will delay the groundwater, prevents the increase in the level of humidity and the occurrence of condensate.

Then you need to install beacons.

Chernovaya screed and laying insulation

After that, cement screed with a thickness of 40 mm is poured.

The plates of foam places in a checker order to the solution, tightly configuring each other. The insulation will not allow to leave warmth and will not give to penetrate cold to the house. After a break for 2 days, giving the screed to dry.

Finishing

The final stage of work is a finishing screed. To create a smooth surface to the heat insulator, you need to attach beacons.

Then the entire design is poured with cement mortar, the layer thickness is approximately 70 mm. The reinforcing mesh is placed on top of it, which will not give the screed to crack and fall apart. The surfaces are allowed to dry, after which they are cleaned from the influx and align.

Warming with clay

If it is used as a heat insulation, it is necessary to carefully calculate the thickness of the heat insulating layer and the size of the screed, since the floors in a private house are experiencing large loads. The specialists are recommended to use the clamzite of different sizes, then the insulation layer will be more dense.

The whole process of work is similar to those described above. Layer of claying thickness of at least 10 cm puffed over a rough screed. When laying should not be a slope, the layer should be smooth, otherwise the insulation of the floor will not be reliable. Control measurement distance between beacons and backfill can be carried out using a special template or roulette.

Before filling a finishing screed, clamzite is treated with cement milk: it will accelerate the grasp of the insulation, making it more durable. The reinforcing mesh, laid from above, will save the surface from moving, cracking.

We can not use the floor within a week. Final strength The whole design will reach in about a month. After that, it is possible to lay decorative flooring.

Concrete base isolation

For floors, which overlap is a monolithic reinforced concrete plate, as a heater, it is better to use rigid plates of mineral wool.

You can make this design even warmer and durable using a concrete screed, covered over the heat insulator. Minvatu must be pre-covered with a mounting grid.

Warming on lags

If the house is old, before you insulate the floor in it, you often have to remove the overlap and delved into the ground.

After that, it is placed black, most often wooden coating. A layer of waterproofing is mounted on top of it: it can be mastic or rolled materials. They will protect the insulation and lags from moisture.

Then on the draft floor with waterproofing, lagows are mounted (boards or bars of wood). All wooden elements must previously be treated with an antiseptic.

Montage Minvati

For insulation of wooden structures, it is better to use mineral wool (it does not burn). If the material is in a roll, then it is unfolded by a solid web, and stacked, without cutting pre-in pieces.

Fix wat stapler. Mates or plates are tightly laid in between lags.

Vaporizoation and floor laying

The insulation is laid a layer of vaporizolation. It can be a dense polyethylene film or professional membranes.

Then the finishing floor is mounted, leaving the ventilation gap between it and insulation. Under it, experts recommend installing a fine metal mesh, it will not give rodents to penetrate the house.

Floor insulation in its own home - the work with which one person can cope. The main thing is to choose the most suitable and high-quality insulation and comply with thermal insulation technology.
