How to insulate the floor in the country without disassembling it. Which insulation is better for a wooden floor in a country house How to insulate floors in a country house

The dacha is a meeting place for family and friends, a territory for relaxation, peace and unity with nature and one's dreams. Whatever the size, scope, style and features of your dacha, it should be comfortable for living and cozy, which means you need to learn how to insulate the floor in the dacha so that it is pleasant to be inside.

Starting in autumn, cold weather approaches us, at first slowly, appearing only at night, and then more and more distinctly, reminding us of itself with the first frosts. The winter period can completely surround the house with a veil of snow elements, and spring prepares streams of melted snow and temperature changes. All these influences directly affect your home, its surface and internal microclimate. Insulation of the floor in the country house will allow you to keep dampness and cold on the way to your rooms, keeping the temperature level inside, which prevents the appearance of dampness, mold, and condensation. Such work will not only improve your life in this house, as numerous reviews say, but also keep the structure itself - walls, floor, ceiling - in good condition, which will allow you to use the house for a long time without carrying out repairs and restoration work.

waterproofing layer

The first encounter with low temperatures occurs in the basement - the place where the foundation passes into the subfloor. It is here that it is worth making waterproofing and insulation if you do not want to deal with the consequences of floods and dampness later. The waterproofing procedure involves laying an impregnating layer or roll film. You can use special mixtures for filling the floor, which will reliably protect against moisture, it is very convenient. Roll coating applicable only for perfectly flat walls without cracks, in addition, they must be dry, so work is best done in the hot season.

The floor in the country is most often concrete, because this material is the most durable and comfortable, so it will become your basis. Before carrying out any kind of work, it must be cleaned of contaminants and dried. Mold stains or other growths must be removed. If the room goes underground, waterproofing should also be done along the perimeter of the walls, since water will rise along their entire height, especially during the snowmelt period.

General procedure for work and insulation materials

To organize the floors in the country with your own hands, you need correct sequence actions. First you need to prepare a draft floor - this is the base surface that remained after the work of the builders. A layer of insulation is built on it, which is selected individually, and a finishing layer is already mounted on top of it. flooring. At each stage, it is important to observe the technique of performing work so that moisture and dust do not accumulate between the layers.

Floor materials for summer cottages have long been tested in practical use and selected for construction sales. Styrofoam is a material made from a polymer, it has a low density and good thermal insulation properties. This material can be used in sheets, blocks or as bulk filler. It is quite light, so it needs to be firmly fixed. A warm floor in the country can also be made using polystyrene foam. This is a more expensive material. There is also a liquid form of it - penoizol, it can also be used. Mineral wool insulation is used less frequently, as it can sag over time, forming gaps.

Preparation for independent work on thermal insulation

For the arrangement of the floor in the country will need basic set tools. This is a screwdriver and a set of screwdrivers for working with self-tapping screws, a hacksaw for working with wooden beams, stationery knife for shortening and trimming material. For measurements, you will need a tape measure and a building level. To fix the insulation, you will need a furniture stapler. For impregnation, you will need an antiseptic and a primer, as well as a brush for applying it. To organize a lattice for laying insulation, you will need wooden bars or sheets that you can saw through. For the top layer you need Decoration Materials. The calculation of the cost of floor insulation in the country can be made by measuring the footage of the room. Photo and video materials can help in the work, which will consider in detail each stage of the work.

wood floor insulation

The wooden floor often falls into disrepair. If you bought a house or inherited it, you need to meticulously inspect its condition. It happens that a house, quite suitable for decoration and planning, turns out to be resting on half-rotten beams. Perhaps the builders did not impregnate them with a solution that improves the properties of the tree, and over time it became damp. If the floor is not suitable, you need to disassemble it. All boards must be torn off from the base in the form of an overlap of beams. This is laborious work, but it must be done.

The floor in the country is better to impose from new boards. It is better to fix them with self-tapping screws, not nails. They are easier to handle and dismantle. In addition, their fastening will not be a test for the tree, since the hole can be shot with a power tool. Boards should fit snugly against each other so as not to let air in from the basement or underground space. It, by the way, can be filled with a metal mesh to prevent the movement of rodents if they start.

A layer of insulation will provide a warm floor in the country. Install wooden logs around the perimeter of the floor - bars, between which insulation will be laid. The distance between them can be from 40 cm to a meter. A vapor barrier film is laid on them, which is fastened with a furniture stapler. Gaps or gaps should be sealed. Fasten the film at all folds so that it adheres to the joists and the floor. Both polystyrene foam and polystyrene foam are suitable for warming floors in the country. Mineral wool is recommended as a filler for seams and joints. Insulation blocks are easy to cut, crumble and cover, so everyone can handle this job. The layer can be from 5 to 20 cm, depending on whether you plan to live indoors in winter.

Upper layer will already become a finish coating, it can be laid from chipboard, wood panels, plywood. Here it is important to level the base so that all the boards are, as it were, on the same plane. Between them, gaps are permissible, and even necessary, which will allow the material to expand and contract depending on humidity, in its natural mode. Fastening here should be done carefully so that there are no protruding heads of self-tapping screws or other irregularities on the surface. Such a floor in the country house will retain the heat that will be produced by a fireplace or convector, and will also keep the temperature inside slightly higher than that outside, even during your absence.

The device of a concrete floor in the country

The specificity of floor insulation in a country house with a concrete base allows several ways to produce insulation. The first resembles working with a wooden floor, and the second is suitable only for a concrete base. So, floor insulation with the help of a film and layers of heat-insulating material in the country can be done by hand. The film is laid in one layer, its footage is easy to calculate. In this case, preliminary work is necessary - sealing cracks and chips with the help of cement screed and putties.

After the surface dries, a wooden frame is adjusted to it. The distance between the beams is at your discretion, but it is better that it is no more than 80 cm. A film is covered on this base and fastened with a stapler. The space between the bars is filled with heat-insulating material.

Its thickness may vary, but it is worth considering that a small gap is required between this layer and the upper floor covering, that is, the height of the log should exceed the height of the insulation layer by 0.5-1.5 cm.

The second option for the floor in the country is a little more interesting. First, the floor is leveled with putty or screed. Next, you can lay a layer of roofing material for additional insulation. A heater is laid on it - always in the form of plates. They are glued together to form a single layer. Filling with a screed holds them together completely. After it has dried, the floor covering is laid, depending on your preferences.

Underfloor heating with the help of technology

Those who wondered how to insulate the floor in the country, probably heard more than once about “warm floors”. This is holding the heating system under the surface of your floor. For this purpose, a cable or flexible tubes can be used, through which water is driven. The source of heat can be any heating boiler - gas or electric. Such a system is laid on top of the insulation layer, distributed under the entire floor, in the form of a circular or parallel fastening of wires or tubes. Such heating will help to feel comfortable and maintain the temperature of the air in the room. In this case, experts will tell you better how to make the floor in the country.

The floor in the country creates an atmosphere. It's one thing when you can safely walk on it in socks, or even barefoot, sit on the carpet in the evenings, allow children to fiddle with toys on the floor, and quite another when it's icy and any contact with it only threatens to catch a cold. For the floor in the country, not so many materials are needed, and working with them is simple and straightforward. Settled in new house, or deciding to spend the winter outside the city, be sure to remember about the arrangement of the house, because its most vulnerabilities- floor and roof. The insulated floor in the country will save money on heating and subsequent repairs, so be sure to spend everything necessary work. They can be done year-round, unless your subfloor is damp.

The floor, laid illiterately, can cause a significant amount of heat loss. This is especially felt in a country house built on the ground. If during the construction of the cottage the technology of laying the floor was not observed, then it may be necessary to insulate. About how in the country, and will be discussed in this material.

Material selection

In search of an answer to the question of what, you will have to explore several options for materials. Such qualities as durability, weight, moisture resistance and thermal conductivity deserve special attention. If the task is to do it yourself repair work, then it is worth considering the ease of use.

Most often used for these purposes:

expanded clay;
Styrofoam;
perlite;
mineral wool;
stone wool;
technical plug.

Each of the presented heat insulators has both pluses and minuses. When choosing, it is worth considering the size of the cottage, the climate zone, the time at which it is planned to live in this house, etc.

Mineral wool - the most popular insulation

The most common material for repair work in the field of floor insulation is mineral wool. It is made from various raw materials, which allows it to be classified into glass, stone and slag.

What are its benefits? First of all, she is easy to work with. Cotton wool is easy to cut and fit. It has excellent performance properties: it is chemically neutral and is not afraid of exposure to high temperatures.

With its help, you can not only improve the thermal insulation properties of the cottage, but also solve the issue of sound insulation.

When choosing mineral wool as a heater, one must take into account its ability to absorb moisture. In this case, one cannot do without laying a layer of material having vapor barrier properties.

The thickness of the mineral wool layer depends on many factors. This is the purpose of the room, and the climatic zone. If you plan to live in the country all year round, then the layer of such insulation should be about 20 cm. For living in the warm season, 4 cm is enough.

Insulation options

In a country house, floor insulation is most often done in one of two possible ways:

by lags;
on a concrete base.

The first method is applicable for both wooden and concrete floors. It has one significant advantage: there is no load on the insulation, which allows you to choose any option as it.

When choosing the second method, serious pressure will be applied to the material defined as a heater, which imposes a number of restrictions on it, it must be strong and dense.

wood flooring technology

It is worth paying attention to the two-layer insulation system. The design in this case has the following layers:

draft floor;
warming;
clean coverage.

The main task of the subfloor is to perform a thermal insulation function. It can be made of rough boards attached to beams. This option can be called the most common and popular.

However, it also has a number of disadvantages. Over time, the prefabricated structure becomes unstable and loosens. To eliminate such a problem, it is recommended to attach the cranial beam to the lags along the lower edge and lay the board segments in the formed pockets. The warming process consists of the following steps.

Surface preparation

The first step is to prepare the foundation. To do this, the old coating is dismantled. The surface is cleaned from dirt and dust.

As practice shows, most cottages have uneven floors. They need to be leveled. This will make future repairs easier.

To do this, you can perform a concrete or cement-sand screed.

The lags are laid at a distance of 60-100 cm from each other.

Waterproofing

The organization of waterproofing is carried out on both sides of the insulation layer.

If penoizol is used as a heater, this step should be omitted.

Insulation laying

Mineral wool is cut into layers depending on the size of the grooves and placed between the lags. The width of the fragments should be slightly larger than the distance between the beams. So the material better fills all the cavities.

If the room is high enough, then the insulation can be laid in two layers.

Finished floor laying

This stage is final. Plasterboard, laminate, plywood, ordinary boards, etc. can be chosen as cladding.

Concrete floor insulation technology

Insulation of the concrete floor deserves special attention, as it is usually very cold. For thermal protection, the lag technology discussed above can be applied.

Another option is floating floors. In this case, it is necessary to arrange the cement screed. It is recommended to assign the function of a heater to a material such as extruded polystyrene foam, since it has a high compressive strength and better withstands mechanical stress.

As a result, the floor will consist of several layers: a concrete base, and a floor covering.

Modern methods of concrete floor insulation

When working with a concrete floor, there are a number of additional ways to achieve the task. This should include:

Floor coating with heat-insulating paint

This method has many advantages. Anyone can make these repairs themselves. The paint is suitable for both new and old buildings.

It is applied in several layers on a pre-cleaned floor. Each layer should dry well, only after that you can move on to the next. As a rule, in this way it is possible within a day.

Floor covering with warm linoleum, technical cork or carpet

Carpet and linoleum cannot adequately solve the problem of insulation. However, these options are quite economical.

When choosing a technical cork, you will have to incur significant material costs, but this material is considered the safest for health and is characterized by excellent performance properties.

Covering with plywood sheets or moisture-resistant fiberboard and chipboard

This option is classified as a budget option. These materials can be laid both on the logs and directly on the concrete floor. A more tangible effect can be achieved by laying them in two layers on the concrete coating itself.

It is worth remembering that plywood sheets should not completely coincide with each other. Between them, you need to leave small joints of 1.5 mm, which will prevent unevenness of the finished floor, for which you can choose laminate, linoleum, carpet and other options.

Underfloor heating technology

Installing underfloor heating is a modern way to achieve a comfortable atmosphere in a country house. For this, water or electrical systems are installed.

It is worth noting that this option is difficult to perform after the completion of the repair and bring it to life with your own hands. Therefore, such systems are usually equipped by specialists at the construction stage.

Room insulation

Cold winters still take place, and you need to prepare well for them so that living in the house is 100 percent comfortable. Underfloor heating is the basis on which it depends how pleasant it is to be indoors when it is cool outside. There are convenient options for insulating this part of the building without removing the top layer - it's easy to do it yourself if you follow simple recommendations.

We insulate the floors from the basement - when is it appropriate?

Any wooden house quickly loses heat, this is due to the peculiarity of the material. Therefore, the insulation of all parts related to the external environment is mandatory. The walls are only part general design, which must undergo a thorough heat blocking procedure. The process of working with the floor will solve such problems as:

excessive energy consumption for space heating;
high humidity - relevant for the transitional seasons;
rotting of wooden building elements;
the appearance of fungus, mold, which poses a danger to the health of residents of the house.

Most often, in cottages, floors are insulated above a cold basement, because. in the cold season, they cool down quickly and have low temperature even if the room is heated with the help of its boiler system. Poor or no insulation means icy floors that are useless for carpeting. The problem is solved only by proper insulation, there are simple techniques that can be used without removing the old floor. It is better to spend money on such an event once than to constantly spend extra gas or electricity on double heating rooms.

Floor insulation scheme

In the event that the building has already been built, and there is a need for additional floor insulation, it is more expedient to do this from below, i.e. without removing floors. Benefits of the bottom technique:

the ceiling height in the rooms will remain the same, because there will be no need to raise the floors due to insulation;
no need to specifically spend money on insulating compounds of increased density and rigidity due to the load of furniture, appliances and other items in the house;
you will protect not only the floor itself from freezing, but also all floor structures, which will extend their service life and generally make the home warmer;
there will be a change in the location of the dew point from the inside to the surface of the floor - this will get rid of the decay of wooden elements.

The method of floor insulation from below has only one limitation - the subfloor is too low, in which it is impossible to be for work. Such cottage buildings are quite rare. If this is your case, choose the floor insulation option from above, i.e. with the procedure for opening it and filling it with a suitable insulating material.

Minvata - fiber insulator

Mineral wool is building insulation, consisting of many fibers presented in three separate types: glass; stone or basalt; slags. To work with the floor, basalt canvas is most preferable, because. it is easiest to mount under the floor structure. Of the two options - rolled and mats in the form of plates - choose the second, because. it keeps its shape well. Advantages:

good level of thermal insulation;
simple installation technology;
relatively low level of moisture absorption from environment;
moderate price;
heat resistance and fire safety;
bacteria, mold, fungus do not start in the material.

Flaws:

when laying with your own hands, you must use special protection - gloves, clothing, a respirator, glasses, because. there will be many particles of fibers and dust in the air, causing irritation of the skin and respiratory organs;
moisture protection is required, because the structure is susceptible to vapor absorption;
if installed incorrectly, strong shrinkage is possible;
when laying between the lags, you need to leave a gap to the main structure of 5 centimeters.

Mineral wool floor insulation

If you decide to choose mineral fiber, select the material of the desired thickness. Specific data depends on the climate zone, for example, for middle lane Russia is suitable for an indicator of 100-150 millimeters. Basalt wool is suitable for all types of floors, including the attic.

Styrofoam - air material from granules

Styrofoam consists of foamed PVC granules containing a maximum of air inside, this gives it good thermal insulation qualities. Advantages:

has strength, stability, rigidity;
almost does not absorb moisture - the percentage is lower than that of mineral mats;
has a light weight;
easy to mount, because does not change shape;
inexpensive;
durable, does not mold, does not rot.

Flaws:

subject to fire;
brittle to break;
ventilation of the base is required, because does not pass steam and air.

Styrofoam is also used for floor insulation.

For floor insulation in an ordinary private house, foam boards of the PSB-S-15 brand ten centimeters thick are suitable. At the time of purchase, do not confuse them with granulated polystyrene foam, which easily crumbles into small PVC balls. The latter can also be used as a heater if the repair budget is very small. The material has good thermal conductivity, but has a relatively short service life - no more than ten years.

Polyurethane foam - do I need a device to work with it?

This building material is a foam of two types - light and hard. To work with the floor, the second option is used, because. it does not require special vapor barrier from the basement side and has the best thermal insulation characteristics. The first type is very similar to mineral wool - in the same way, when working with it, you will have to leave gaps for ventilation and waterproof the lower surface. PPU consists of two components:

1. polyol or hydroacid with emulsifiers, polyesters and foaming agents;
2. isocyanate or polyisocyanate and diphenylmethane diisocyanate mixed with each other, which are strong reagents in the complex.

High-quality floor insulation with polyurethane foam

Building material advantages:

fills all cracks and corner spaces thanks to spraying technology;
suitable for bottom mounting;
does not shrink, fireproof;
does not require vapor protection;
durable - lasts up to 50 years;
high level of adhesion to all materials;
high installation speed;
complete environmental friendliness;
has no seams, because is a single sheet after drying.

Among the shortcomings, one can single out the high cost, the need for skill in applying and the use of special equipment - a high-pressure apparatus that can be rented.

Mineral wool and foam plastic, having the form of plates, are mounted on the “wrong side” of the floor from the basement side using the same technology. Attach bars with a cross section of 50 to 100 millimeters to the beams from below. Lay a layer of material for thermal insulation on top, like on shelves. The beams should be placed under the “top” floor at such a distance that a few centimeters remain between it and the top surface for ventilation. Hem the heat-insulating “pie” from below with boards, apply waterproofing to prevent vapors from penetrating into the material from the basement side.

Installation of floor insulation

The waterproofing function can be performed by ordinary polyethylene film - this is the cheapest and most convenient option. A moisture-proof membrane will cost more - it is stronger and does not prevent air movement, unlike cellophane. In order for the materials to last longer, the film will need to cover the upper surface of the main thermal insulation. The order of all layers from top to bottom will be as follows:

1. flooring;
2. concrete screed or expanded clay;
3. overlap;
4. vapor barrier from the side of the room;
5. a layer of mineral wool or polystyrene;
6. waterproofing from the basement;
7. holding boards.

Application of PPU is carried out on a specially prepared floor surface, it is necessary to remove dust, debris from it and make sure that it is completely dry and free of grease. The foam does not adhere to polyethylene and greasy compounds. The procedure can be carried out at temperatures above 10 degrees, otherwise the material will not stick to the ceiling as it should.

For work, you will need a high-pressure apparatus - it is very expensive to buy it, you can rent it in specialized companies. It is connected to two containers with the first and second components. When the start button is pressed, the compositions are combined in a vortex chamber, then they are sprayed in the form of a fine and light mass. The pressure in the machine must be at least 140 atmospheres. When choosing a technique, pay attention to the current source - the required one must match your home network.

Apply PPU evenly, after putting on protective equipment - goggles, a respirator, gloves. The procedure for a professional is about an hour, if you are confident in your abilities, you can try it yourself, but it will take more time due to insufficient experience. Apply polyurethane foam not only to the space between the lags, but also to the lags themselves - this will protect them from rising steam from the ground.

After applying a layer of about 10 centimeters, turn off the machine and leave the room to dry. Complete hardening of the material and its perfect adhesion is achieved in two days. There is no need to specially process the bottom layer, because. it is not exposed to moisture and holds well to the top of the floor.

Insulation of the floor on the old coating, how to arrange thermal insulation of the floor: advice from insulation experts!

Underfloor heating in a country house is a prerequisite for a comfortable stay in winter period. The funds invested in insulation are compensated by lower heating costs and the absence of colds in the family.

Almost all technologies prescribe the dismantling of the top coating and the laying of mineral fiber or polystyrene foam insulation between the joists of the floor frame. What if the need for thermal insulation of the floor fell on the heating season? The traditional sequence of thermal insulation work with the removal of the coating can create many problems for the owners living in the house.

On construction forums, the owners of problematic cottages offer their options, from which you can choose the most acceptable one.

For floor insulation along the logs, our experts recommend


Rockwool Light Butts	Baswool Light 35	URSA GEO M-11

The effectiveness of surface insulation depends on the quality of the materials used and their technically flawless installation.

Ways to insulate the floor without its preliminary installation

In temperate climates, flooring with oriented strand boards (OSB) is practiced. The coating structure is characterized by low thermal conductivity. For decoration, several layers of colored varnish are applied to the surface. Naturally, the base must be fairly even. As a waterproofing, you can use a fairly dense polymer film, sealed at the seams by heat welding.

In a region with difficult climatic conditions, hydrophobized mineral wool panels of increased density are recommended for floor insulation. In the budget version - extruded polystyrene foam 30 mm thick. The insulation can be closed with any sufficiently strong and moisture-resistant panels; linoleum, laminate or material with identical properties can be used as a front cover.

A significant advantage of this design is the possibility of dismantling and reusing materials for arranging better thermal insulation.

Mineral wool floor insulation

panel stone wool, the thermal conductivity of which is sufficient for the implementation of the most complex projects, is characterized by the stability of working properties, chemical inertness, and a long service life.
The material is environmentally friendly, so the restrictions on internal insulation has no living quarters. It is possible to use semi-rigid panels for insulating concrete screeds under floor tiles.
Moisture-repellent impregnation of mineral wool panels works quite effectively, but the presence of a damp basement determines the need for film or mastic waterproofing.

More affordable polystyrene foam and expanded polystyrene retain their insulating properties even in a damp environment. To seal the system, it is enough to seal the seams and interfaces with moisture-resistant putty or glue with construction tape.

Unfortunately, the material's uniquely low thermal conductivity cannot compensate for its combustibility.

When choosing a heater, this disadvantage should be taken into account in the first place.

For floor insulation under the screed, our experts recommend

Indeed, the proposed schemes are workable and can be used in the budget version of floor insulation. It should be noted that manufacturers of cheap facing materials as before, they use old technologies with the use of phenol-containing components. Savings take place, but it is better to refrain from purchasing cheap panels and heaters at the selection stage.

How thick should modern floor insulation be? It is difficult to recommend volumetric coatings, since raising the floor by only 80 mm significantly affects the reduction in the volume of the room. The low thermal conductivity of both heaters allows the use of plates with a thickness of 20-30 mm. Even with panel cladding, the floor height will increase by only 40-45 mm.

How to insulate the floors in the country with your own hands without removing the old floor

How to insulate the floor in the country: insulation of plank structures, concrete floors and screeds under linoleum covering

In this article we will talk about how to insulate the floor in the country. available means and with your own hands. The topic of the article is of significant interest, since over 30% of heat loss in a country house falls on the floor. Meanwhile, improve energy efficiency building object by means of floor insulation is not so difficult and you will surely cope with this task on your own.

floor insulation scheme

Important: If the power supply is unstable, then for the operation of the power tool during the repair, you will need to rent a diesel generator to give.

Features of thermal insulation of floors in country houses

Insulation of floors in the country depends on the type of foundation of the subfloor of the country house and the flooring. Therefore, before proceeding with thermal insulation work, it is necessary to determine the type of floor and analyze its condition.

Do-it-yourself floor insulation in the country house is advisable for the following reasons:

minimization of heat losses;
elimination of drafts;
prevention of dampness and mold on the flooring substrate;
increase in the operational resource of the subfloor.

So, there are reasons for carrying out thermal insulation work, it's time to consider how these works are performed.

Insulation of plank structures

Slot filling pattern

The question of how to insulate a wooden floor in a country house is relevant for most owners of old country houses.

The need for thermal insulation is caused by:

the presence of a void between the boardwalk and the ground;
the presence of gaps between the boards.

Important: In the gap between the ground and the boardwalk, rodents in most cases start. This is another reason to fill this space with dense thermal insulation material.

In the photo - expanded clay backfill

In the case of boardwalk optimal solution will be the insulation of the floor in the country with expanded clay.

We do it like this:

We free the room from furniture and other elements of the surroundings.
We dismantle the plinth.
With the help of a nail puller and a chisel, we dismantle the boards.

We mark each dismantled board in accordance with its original location. In addition, we mark its direction on the board.

If this is not done, the flooring from the boards at the end of the work will lie unevenly.

Having raised the boards, we level the ground and carefully compact it in the intervals between the lags. For these purposes, you can use a manual rammer, which you can make yourself.

Tip: When leveling the soil, it is advisable to carefully examine its surface for the presence of anthills and rodent burrows. If there are any, they must be destroyed - summer craftsmen fill in the holes of rodents cement mortar with the addition of crushed glass.

With an anthill under the floor, everything is somewhat more complicated, and therefore it is better to use special tools designed to remove insects.

We lay waterproofing on top of the compacted soil, for example, plastic wrap.
Expanded clay is poured over the waterproofing layer. In order for the backfill to lie more evenly, it is better to use expanded clay of a fine fraction.
Expanded clay, covered between the lags, is rammed until its surface is equal to the surface of the lag.
Further, the boards are laid in their original place in accordance with the original numbering. So that the surface of the laid floor does not subsequently deform, we fix the boards not with nails, but with screws.
The gaps formed between the boards can be caulked if the plank flooring is used as a subfloor. If the plank coating is finished, the cracks formed after the bulkhead of the boards are puttied, after which the entire coating is cycled.

Insulation of concrete floors

Today country houses from block containers are widely used. The floors in such buildings are thermally insulated already from the factory. Much more difficult is the case with modern dachas where a concrete screed is used as a subfloor.

In this case, it all depends on what will be the finish coating.

For example, if a laminate is used as a coating or parquet board, for thermal insulation, you can use special substrates (cork, polyethylene foam or polystyrene foam).

Cork underlay is a rough coating made from crushed oak bark, pressed with the addition of an adhesive.

In the photo - cork substrate

Such coatings, depending on the thickness and type of binder, can be completely natural or mixed with bitumen or rubberized.

These substrates are good for a low degree of thermal conductivity and excellent soundproofing properties. But, most importantly, the cork substrate absorbs the slight relief of the concrete screed.

However, there are also disadvantages. The cork substrate is afraid of moisture, which is solved by pre-laying a plastic film on the screed. Perhaps the most important disadvantage is the high price.

Polyethylene foam underlay

Foam polyethylene, as a heat-insulating substrate, is characterized by resistance to excessive moisture, excellent thermal conductivity and ease of installation. In addition, the price of this material is an order of magnitude lower than the cost of analogues. The lack of material is fragility, since this coating quickly loses its shape under mechanical stress.

Styrofoam underlay

Expanded polystyrene, as a substrate, is a two-layer coating. The top layer is foamed - expanded polystyrene, and bottom layer- it's foil. Such a coating is characterized by an average cost combined with high thermal insulation qualities. Less warm are single-layer modifications made of extruded polystyrene foam.

Insulation of the screed under the linoleum covering

Multi-layer plywood laid on a concrete screed

If we insulate the floor in the country house under linoleum, a slightly different approach will be required. In this case, OSB boards or plywood are laid on top of the leveled concrete screed.

Oriented strand board OSB is characterized by low thermal conductivity, and therefore the instructions for their installation provide for laying in one layer and linoleum can be laid on top. Particle boards are laid on pre-laid waterproofing. The plates laid in a checkerboard pattern are fixed with self-tapping screws. (See also article Country construction: peculiarities.)

Important: In the slabs, before screwing in the screws, we drill out the sweat under the caps.

Conclusion

Now that we have looked at how to insulate the floor country house, you can apply the knowledge gained in practice and make your country house more energy efficient. If you have any questions, watch the video in this article.

How to insulate the floor in a private house and in the country: video

This is especially true for private buildings that are not protected from the cold from the outside. Here you need to think about how to insulate the floor in a private house and at the same time carry out all the work correctly. Remember, only high-quality insulation of the building from the floor will prevent the growth of mold in the room and provide an optimal microclimate in the building. We talk about how to insulate the floor in a country house or in a private country house with our own hands cheaply, but with high quality, in this material. For clarity, the video is attached to the material.

Important: insulation and wooden house, and brick houses are carried out by analogy. The main criterion for choosing a heat-insulating material should be the base of the floor (concrete or wood).

Expanded clay insulation

This type of insulation (expanded clay) is a bulk material with a different fraction

This type of insulation (expanded clay) is a bulk material with a different fraction. The structure of expanded clay pebbles is porous, which allows you to perfectly retain heat in the room and not let the cold into it. It will be better if the expanded clay is covered between the layers of the screed at the construction stage. But you can also insulate the old concrete floor in a private house by dismantling it to the foundation.

To insulate floors with expanded clay, work is performed in the following sequence.

A layer is laid on the foundation base waterproofing material. It can be both roofing material, and an ordinary film 2-3 mm thick. In this case, it is very important to lay the material end-to-end, fixing the edges with construction tape. It is also necessary to throw the edges of the waterproofing onto the walls of the foundation exactly to the level of the base of the future floors.

Now you can pour a layer of expanded clay. The optimal layer is 10 cm, which replaces brickwork with a thickness of 70-80 cm in terms of thermal insulation properties.

Important: in order to further enhance the thermal insulation properties of expanded clay insulation, you can use a material of different fractions. So the pebbles of baked clay will lie more tightly.

The next step in warming the floor with your own hands will be pouring expanded clay with special gypsum milk. This will enhance the adhesion of the cement to the insulation and prevent the movement of stones under the screed.

And now you can fill the floor screed, having previously reinforced it with a metal mesh.

Important: the floor, properly insulated with expanded clay, is ready for use in a week. But it is better to put heavy pieces of furniture on it in a month. And during this period, the readiness of the cement-expanded clay base can be checked using a simple can. They put it on the floor with the neck down and monitor the formation of condensate in the jar. If one has appeared, it means that the floor has not yet completely dried out and is not ready for full enhanced operation.

With your own hands, regardless of the floor in a stone or brick house, the floors can be insulated with mineral wool or expanded polystyrene slabs

With your own hands, regardless of the floor in a stone or brick house, the floors can also be insulated with mineral wool or expanded polystyrene slabs. Today, by the way, Rockwool stone mineral wool with the inclusion of basalt fiber is in great demand. Mineral wool "Rockwool" with a thickness of 5 cm is able to create thermal insulation equal to the thickness of brickwork 90-100 cm.

Expanded polystyrene or mineral wool are great for insulating a wooden floor on logs. Here it is better to do the work yourself in this order:

First, the screed is poured, which must dry completely.
Now a layer of waterproofing is laid on the floor. In this case, you can use a regular oilcloth with a density of 200 microns. It needs to be laid butt and overlap. On the walls, you need to throw waterproofing to a height of 15-20 cm. Then, when laying the floor, all excess will be cut off.
We mount logs on the waterproofing layer in increments of 30-50 cm (depending on the finishing floor covering).
Between wooden lags under the wooden floor we lay plates of mineral wool or polystyrene foam.
From above, the installation of a floor covering from a tongue-and-groove or terraced board is carried out. Or you can simply lay a third-grade board, and already mount laminate, carpet, linoleum and other materials on it.

Floor insulation between floors

If you want to additionally insulate the floor on the second floor or attic floors, then you can use the same technology as in the case of mineral wool

If you want to additionally insulate the floor on the second floor or attic floors, then you can use the same technology as in the case of mineral wool. To do this, it is enough to carry out work, removing the old layer of the floor covering (as a rule, this is wood) and laying the necessary heat-insulating material under it. Such insulation will provide warmth in the attic (second floor) or prevent the penetration of cold into the house from the attic (second floor).

Important: when insulating the floor from the side of the screed on the ground floor, make sure that the density of the insulation is not less than 35g/m3.

How to insulate the floors in a private house with your own hands without removing the old floor

How to insulate the floors in a private house with your own hands without removing the old floor - instructions

Thermal insulation of any building is necessary and mandatory, and no explanation is required for such a statement. With regard to a private house, the task is somewhat facilitated, since the basement in it, if not heated, is at least insulated in some way. Let's figure out in detail how to further reduce the level of heat loss through the floor without dismantling the old one, what to consider and what materials to focus on if the work is done only by one's own hands, without the involvement of professionals.

Floor insulation in a private house is carried out at the construction stage. Therefore, if it is intended without removing the old floor (which is the boardwalk), then the choice of techniques and materials is somewhat limited. Additional fine finishing does not count - it will have to be dismantled during insulation.

What is needed for insulation

Products of the class "vapor barrier materials"

The range is quite large both in terms of manufacturer, modifications and a number of other parameters. The durability of both the insulation and the outer coating directly depends on this layer. Therefore, it is not worth saving on vapor barrier material and purchasing products from companies with a good reputation. In this case, the concept of more expensive means - more reliable, better.

There are enough options for floor insulation, consider the most popular and inexpensive:

Expanded clay

There is a lot of controversy about the appropriateness of its use. Arguments against using it as a heater - it is difficult to obtain a layer that is uniform in thickness and density. Plus, you will have to shed the backfill with cement mortar, and this is dust and dirt.

The first problem is solved automatically if you purchase expanded clay with granules of various sizes. In this case, the heat-insulating layer is sufficiently dense and durable. It is difficult to say about the second judgment. It all depends on how and with what the design of the final coating is planned. Therefore, it is impossible to deny a priori the possibility of using expanded clay for floor insulation in a private house.

Styrofoam

A whole group of materials, subdivided into several modifications, depending on the manufacturing technology. Basically, the owners are guided by the so-called "clean foam". Even if the finish is hard, then using it, according to the author, is impractical for several reasons.

First. The material is porous, so it crumbles easily. Cutting sheets, sizing, obtaining even joints - to do all this in the sense of practical implementation is a certain difficulty. Yes, and the amount of waste will be very impressive. And this directly affects the cost of insulation.

Second. Since the old floor is not removed, a visual inspection of the bottom of the room under the flooring is not carried out. And if there are already moves made by rodents? Considering that they like to “nest” in foam plastic and gradually destroy it, then the prospect of saving on such a heater is rather doubtful.

To reduce heat loss through the floor, it is worth using polystyrene (extruded). Its plates practically do not absorb liquids, they are durable, so working with it, as those who have come across this product, is a pleasure.

polyurethane foam

Also board material. Unlike the above insulation, the products are reinforced. Only not with the usual grids, but by adding some components to the original mass. This is mainly crushed aluminum, fiberglass.

mineral wool

So we are talking about the insulation of floors in a residential building, then or ecowool. or stone. The range of products is so impressive that you can choose exactly what you need in terms of dimensions, thickness, execution (rolls or plates). But if the floor insulation in a private (and in any other) house is done with mineral wool, then you will have to think about a hard finish, moreover, mounted on a special frame - the material is elastic and easily squeezed through.

The procedure for warming the floor of a private building

Inspection of the base

This must be done at least in order to determine what materials and in what quantity will be needed to eliminate defects. Moreover, the skirting boards are unambiguously dismantled.

Seal all cracks

There are several options, since laying boards is already a partial removal of the old floor.

Mounting foam. But only for large gaps. Although this is not the cheapest way to seal them, perhaps only around the perimeter of the room.
Ruberoid or polyethylene film. If it is planned to lay a slab (sheet) insulation, characterized by the correct geometry, then sand is added to further level the base.
Plywood. In fact, a kind of so-called dry screed. Sheets are sewn onto the old wood flooring by hand pretty quickly.

Floor vapor barrier

Fastening the material with nails is a big mistake. Staples only, using a construction stapler. The vapor barrier is mounted over the entire area of the room, with a small inversion on the walls.

Insulation installation

Since the old floor is wooden, the work is not difficult. The manufacturer always recommends how to fix individual samples of insulation. For polystyrene - special dowels, mineral wool - nails with a large hat.

Before working with insulation, it must be taken into account that for soft (or loose) materials, one more crate will have to be mounted, and fragments of thermal insulation should be laid between its ribs. If polystyrene is used, then it is covered with chipboard, OSV or similar plates (sheets) from above.

Arrangement of waterproofing

If this is neglected, then the result of wet cleaning in the room will be leaks. Moisture through the floor covering will go down - to the insulation and boards of the old floor. The consequences are known - rot, destruction of wood and the need for unscheduled repairs.

If a laminate is chosen for the finishing coat, then for additional floor insulation it is enough to use rolled foam with a reflective layer (foiling) as a substrate. When deciding to decorate a room with linoleum, one should focus on the insulated modification of this product. It costs more, but the process of thermal insulation is greatly simplified.
To optimize costs, you should familiarize yourself in detail with the characteristics of all heaters, in accordance with the principle of sufficiency. The main thing is that in this room it was possible to achieve a significant reduction in heat loss. If it is difficult to make engineering calculations on your own, it makes sense to invite a specialist. It is better to pay than to choose the wrong insulation and make a mistake with its parameters (thickness, density).

There is enough information on methods of floor insulation in a private house and recommendations on the choice of materials. The decision is yours, reader.

Insulation of the floor in the country

Insulation of a country house from the inside is a multifaceted problem and affects almost all owners of country houses. First of all, it concerns not only those who start new construction, but those houses that were built a long time ago. Many of our country houses were built in economy mode, therefore, first of all, advice on floor insulation for old houses is relevant. These tips can be applied to new construction as well.

If you are going to live in a country house during the cold period of time, then advice on floor insulation in the country for those will come in handy. If you have an old house, the floor is naturally cold, and as a rule, consists only of floorboards and that's it. If you do not want to completely change the old floor to a new one, then you can make an “insulating sandwich”. Most often, this process is similar to making a sandwich. Some options:

glassine - insulation - glassine.
draft floor - then ecowool, or mineral wool - finishing. At the same time, the former finishing floor can become a rough floor.
rough surface - expanded polystyrene foam - finishing floor.

Do not insulate the floors with foam, it will simply be gnawed by mice. It is better to replace the foam and use polystyrene foam as a heater. These are different things. The exact name of this material for floor insulation is extruded polystyrene foam.

Its main advantages - it does not burn, does not rot. In the markets and hardware stores it is found under the names: penoplex, styrodur, styrofoam. This is a good insulating material for a country floor, at a price more expensive than polystyrene. It is better to use expanded polystyrene foam, it is dense, mice will not want to eat it, it is multi-colored in stores.

Insulation of floors in a country house

If you change the floors entirely, then it is logical to immediately lay a heat-insulating layer. Especially if you decide to live in country house constantly. You can use such a scheme so that the floor insulation in the country house is really warm and of high quality. Warming the floor in the country can be done according to the following scheme, I describe it in layers, starting from the bottom:

draft floor,
vapor barrier film
thermal insulation,
vapor barrier film
ventilation gap,
clean floor.

A very important thing is vapor barrier. It protects the insulation from moisture, otherwise it will get wet and will not keep warm. The cost of material for vapor barrier depends on the manufacturer. It costs differently for different manufacturers. You can choose according to your wallet. The thickness of the insulation is chosen depending on whether you will live in a country house only in the summer or permanently. If it is permanent, then the recommended thickness is 200 mm, if only in summer, then 100 mm is enough.

There are certain difficulties in choosing a heat insulator. Confused by the abundance of similar materials and instructions, as well as friendly assurances from manufacturers that only their products are the most suitable for summer cottage insulation. Attempts to "try on" materials to their conditions lead to conclusions that you can draw yourself:

Insulation of a country house from the inside leads to a loss of usable area and, if possible, it is better to refuse it.
Heat-insulating plate materials are not able to tightly fit the hollows of a log cabin.

One of the options for insulating a log country house is to insulate it with ecowool, simply wrap the house with a “cotton blanket”, and mount a frame on top of it for a finishing coating. As a finish, you can use popular siding, an expensive blockhouse, lining, promising OSB or budget ADC boards, followed by painting or plastering.

Construction secrets: floor insulation in the country

Cold floors are a pain in the ass, especially when you're over…twenty…

Therefore, floor insulation - although not a big secret, but greatly improves the quality of life ...

Insulated floor

The work, of course, is not very simple, but you can do it yourself!

I will share my experience.

We did it like this:

They removed the old floor and removed the old insulation (glass wool)

We swept and marked the lags

Laid wind membrane

We lay the heater at 200

On top again the membrane

Sew up with 15 mm plywood

We lay the substrate

Laying the laminate

Finished

We rejoice at the end of the work and (tradition, do not think anything bad!) We wash the new warm floor so that it will serve for a long time!

Just a little, and the rest - we will break it on the side of the updated ship))

For most people, a dacha from temporary housing, which is used only in summer time becomes real country house, in which they come to her even in deep winter. But in order to be comfortable and warm in the country house even in frosty weather, you need to know how to properly insulate the floor in the country house, choose the most suitable technology. It is only necessary to do the whole complex of work even before the arrival of cold weather, so that it becomes much warmer in the country.

Which technology to choose

Floor insulation can occur in different ways. Choosing the right technology, you need to decide how the work will take place:

For concrete;

According to the lags.

Insulation along the logs can be done on a concrete and wood floor base. A clear advantage of this technique is the ability to eliminate the load on the thermal insulation layer. Therefore, when choosing this method, you can lay heaters different type, mineral wool and bulk materials.

If the insulation is placed on concrete base, then it is under heavy load. This may cause deformation of the insulation material. To prevent this, when insulating on concrete, it is necessary to use materials with good performance density.

Attention! To decide how best to insulate the floor in the country, you can watch the video. It quite clearly shows the sequence of the work process, the tools and materials used. In this case, it will be much easier to understand the technology.

As a rule, in the country the floor is made of wood and very rarely poured with concrete. Therefore, in this case, it is better to do insulation along the lags. In this case, the execution time is significantly increased.

Which material to choose

If the question is being decided what material to make the floor insulation in the country, the cost of the insulation plays an important role. The better and more affordable the insulation layer, the better for the owners. Also, great attention should be paid to how durable, reliable, moisture resistant the material is, what thermal conductivity it has, how quickly insulation work takes place with it. Both the quality of work and the operating time of the heater depend on this. There is a fairly large selection of heaters on the market. For a summer residence buy:

Expanded polystyrene extruded;

Styrofoam;

Basalt wool;

Expanded clay;

Technical traffic jam;

Mineral wool.

Each of the materials has its own advantages. The choice of insulation depends on the individual characteristics of the cottage and the effect to be achieved. Having chosen how to insulate the floor, you can begin work.

Warming along the lags

First you need to dismantle the old coating, in many houses it is made of boards. After removal, you need to evaluate the integrity of the subfloor. If it is normal, the lag is laid. The distance between each bar can be chosen up to a meter.

Then, when the logs are fixed, thermal insulation is laid in the space formed between them. As a rule, preference is given to fiberglass, expanded polystyrene, expanded clay, mineral wool mats.

When laying flexible mats, it is necessary to control that the surface, which has a perforated paper layer, is on the underside. The installation of hydrophobized mineral wool materials is done in such a way that the hard side is on top. To avoid problems during installation, the hard side is painted blue.

Attention! When laying thermal insulation, you need to take care of the waterproofing layer. It must be on both sides and be up to 250 microns thick.

A vapor barrier is attached over the lag. Then the flooring can be installed. You can install the same boards that were dismantled at the initial stage.

If there is a second floor, then work also takes place. However, in this case, in addition to two layers of waterproofing, it is necessary to perform the same number of layers of vapor barrier.

concrete floor insulation

The concrete floor itself is very cold. If it is he who is at the dacha, then even a fireplace will not make it possible to make the dacha warm and cozy without a certain set of works. As a rule, in this case, floors are installed, during the laying of which a cement screed is made.

Usually, extruded polystyrene foam is chosen as a heater, it has a good density. Durability, moisture resistance and sufficient strength of the material makes it possible to provide a sufficient level of thermal insulation. In this case, the arrangement of a multilayer cake is carried out, which includes:

concrete base;

Polystyrene layer;

Finish coating.

Also, the concrete floor can be insulated with expanded clay. To do this, a flat base is covered with roofing material or glassine and covered with a layer of expanded clay. The layer thickness must be at least 15 cm, otherwise it will not work to create the necessary level of thermal insulation. From above expanded clay is covered with two layers of a film. It is installed in such a way that there is an overlap on the walls. All connections are sealed with tape. From above, as in the embodiment described above, a screed device is made and the floor covering is mounted.

In domestic climatic conditions, the need for insulation of residential buildings is beyond doubt. Owners of private houses have to solve this problem on their own. Wooden boards, from which in most cases the floors are made in suburban households, deform over time, and gaps appear in the initially tightly knocked down coating.

It is hard to imagine, but up to thirty percent of thermal energy can escape through these cracks in the cold season. As a result, heating costs rise sharply, and the comfort of living in the winter period decreases. To prevent these consequences, it is necessary to insulate the floors with high quality.

The list of materials for floor insulation is quite wide.

Variants of wood floor insulation technologies

The procedure for thermal insulation of a wooden floor should be provided for at the stage of designing and building a house, and then minimal labor costs and financial resources. If it is necessary to perform this manipulation, when the overlap is already ready, the technology for performing work is much more complicated. In this case, it is possible to do the work correctly and insulate the floor from above, directly along the old coating, or with its partial dismantling. There is also the option of insulating the flooring from the bottom of the basement.

In this case, it is more convenient to insulate the floor from the basement side.

Thermal insulation of floors is made from above if the house has a low basement. If at the same time the flooring is dismantled, only logs are left. The procedure is very labor intensive. In the event that the basement is of sufficient depth, the laying of the insulating material can be done from below. This is much easier and faster, since in the process of doing the work you will not have to dismantle and disassemble the flooring if it is in good condition.

The better to insulate the floors in a private house

Do-it-yourself floor insulation in a private house is quite realistic. In this case, a variety of heat-insulating materials are used. Which one is better is determined after analyzing their performance characteristics and the specific conditions in which they will be operated. Insulated floor significantly increases the comfort of living in the house with negative temperatures environment and reduces heating costs.

Ecowool - one of the options for insulation for wooden floors

Styrofoam and expanded polystyrene are widely used, the use of glass wool and mineral wool has its own characteristics. The simplest and cheapest method of insulating the surface of a wooden floor with expanded clay or using sawdust. The so-called dry screed has good performance characteristics.

Advantages and disadvantages of polystyrene foam and polystyrene foam

Many people know that it is possible to insulate the floor with foam. Expanded polystyrene for the floor is also popular with professional builders and home craftsmen. Styrofoam and expanded polystyrene, due to their excellent performance, are most widely used as insulating materials. Except for minor differences, they specifications comparable to each other. Using these thermal insulation materials brings the following benefits:

low cost;
low thermal conductivity;
small mass;
wide area of use;
long service life;
resistance to pathogenic microflora;
ease of installation.

Quite often, the floor is insulated with foam

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

allocate harmful substances when ignited;
prevent the passage of water vapor;
afraid of exposure to direct sunlight;
attractive to rodents;
are destroyed on contact with solvents;
have low mechanical strength.

Characteristics of "Dry screed" for floor insulation

The so-called "Dry screed", which is made from gypsum fiber, is great for thermal insulation of the wooden floor of a private house. The use of this composition implies the following positive aspects:

excellent thermal insulation;
fire safety;
ease of installation;
compatibility with all finishing coatings;
small thickness;
good sound absorption characteristics.

The process of laying a "dry screed" for floor insulation

At the same time, since we are insulating the floor with a factory-made dry mixture, its high consumption should be taken into account: for processing one square meter surface requires twenty kilograms of the mixture. In addition, when water penetrates, the geometric dimensions of the dry screed change, which can lead to damage to the finish coating.

Possibility of using mineral wool

Mineral wool is widely used to provide thermal insulation for wooden floors. The material is made in the form of plates, which are easy to lay on the floor with your own hands.

Mineral wool is well suited for floor insulation

Mineral wool has many positive properties. The material has excellent sound-absorbing and heat-insulating qualities, fire safety, prevents the reproduction of pathogenic microflora, resistant to aggressive chemical environments.

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

Features of the use of glass wool

Glass wool is similar in its characteristics to mineral wool. A feature of its use is that when performing work, you need to carefully ensure that it does not get into the organs of vision or on the skin.

Glass wool - a common option for insulating a wooden floor

The production process is complicated by the need for the employee to use personal protective equipment. The negative quality of this material is its significant shrinkage over time, as a result of which, if improperly installed, thermal insulation is violated.

Pros and cons of using expanded clay

Expanded clay is a clay-based foamed and fired granules of a porous structure. The big advantage of this material is its low cost, environmental friendliness, low weight and long service life of about fifty years. Expanded clay has excellent soundproofing and insulating qualities. Thus, the thermal insulation of the surface of the wooden floor with expanded clay will not make a breach in family budget.

Expanded clay floor insulation - simple and inexpensive

The downside of its use can be considered the need to make a layer of backfill that is significant in thickness, otherwise the wooden floors will remain cold, especially at sharply negative ambient temperatures. In addition, it absorbs moisture well, although it does not lose its insulating properties.

Sawdust is the cheapest material

The cheapest material in terms of cost is finely chopped sawdust. They do not pose any danger to human health, the technology for performing work is extremely simple: the space between the rough and finish flooring is filled with sawdust. Before use, this material must be thoroughly dried for at least twelve months, otherwise it will quickly become unusable. Cutting waste from freshly cut trees cannot be used immediately.

Apparently, sawdust is the most budget option for floor insulation.

By increasing or decreasing the thickness of the layer, the level of thermal insulation is adjusted. In the northern regions with a very cold climate, a very thick layer has to be poured. It is necessary to take into account the attractiveness of this material for rodents and to repel them, add two parts of dry slaked lime to the composition. The disadvantage of sawdust is the occurrence of rotting processes in them when wet.

Modern choice - isolon and penofol

Undoubted operational advantages are the use of such modern materials like isolon and penofol. Izolon is a foamed polyethylene covered with a layer of foil and has excellent soundproofing qualities with a very small thickness. The material does not support combustion, prevents the development of pathogenic microflora and corrosion processes, a two-centimeter layer is comparable in soundproofing and heat-saving properties with masonry in one brick.

Fragments of laying penoizol for floor insulation

Penofol produced in the form of rolls consists of several layers of insulation, on top of which there is a reflective foil. It acts as a screen that prevents large losses of thermal energy.

When using penofol, it is not necessary to carry out additional work on waterproofing or arranging a vapor barrier layer.

The easiest way is laying a double floor

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

The construction technology provides for the laying of logs on which the subfloor will be strengthened. The coating can be made from wooden planks, chipboard, OSB or other similar materials, it is only important that the structural elements fit snugly together without forming gaps.

Arrangement of a double floor - reliable option insulation

Insulating material is laid on the surface of the subfloor between the guides. At the same time, sand should not be used as its quality at high natural humidity, since in this case condensation may form. A finishing coating of wooden boards about five centimeters thick is mounted on top of the insulation. The new coating will have to be painted, as described in the article

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

The most correct floor insulation - according to the logs

When building a new house or dismantling the coating, the most correct floor insulation is the method of performing work on logs. In this case, the insulation is placed between the logs, which serve as the basis for the finished floor. Depending on the design of the building, the basis for the installation of a log and insulation can be a subfloor made on its own logs, as well as concrete pavement or even soil. In the latter case, it is useful to arrange clay castle to protect against moisture with a layer of about 5-10 cm.

Dense insulation can be held between the lags on ordinary nails

In the technology under consideration, the height of the lag and the distance between them must correspond to the height of the insulation and its width. Before installing the floor covering on top of the insulation, it is necessary to equip a vapor barrier layer of a waterproof film fixed on the logs. The joints of the film can be fixed with adhesive tape.

How to insulate floors with your own hands from below without removing the old floor

If a private house has a deep cold cellar, most the right way will perform floor insulation from below without removing the old coating. This does not require choosing a material that can withstand the weight of heavy furniture and other mechanical loads. In this case, not only the finished surface will be protected, but the entire floor as a whole, and the dew point of the floor will shift outward, and the floor will not rot.

When performing such a task, some difficulties lie 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, insulation from below is performed as follows:

first, a waterproofing layer is equipped;
then a heat insulator is located;
on top of it, insulation from water vapor;
then an overlap is performed to ensure the retention of the thermal insulation of the floor.

Styrofoam can be fixed from below with nails with spacers and mounting foam

Adhering to this technology when doing the work with your own hands, you can get the most comfortable temperature regime in the living quarters of the house. The heat insulator should be of low weight, since it will exert a constant load on the fasteners, bulk materials are not suitable in this case.

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

Insulation from the inside with foam or glass wool gives good results. These materials are lightweight and have excellent thermal insulation properties. First, waterproofing is fixed to the lower surface of the ceiling using a stapler. Next, you can lay the thermal insulation boards in such a way that they are held during installation due to frictional forces. To do this, their width should be slightly larger than the distance between the lags. When working with glass wool, be sure to use personal protective equipment for the respiratory system, vision and skin.

Penoplex - a reliable insulation of a wooden floor

A vapor barrier film is applied over the insulation, which is attached to the logs with staples and a stapler. Further along the logs, a frame is mounted that holds the insulation. It can be made from any material that suits you. appearance and durability. Between the retaining elements, gaps are allowed through which the insulation is guaranteed not to fall out.

Step-by-step instructions for thermal insulation of a wooden floor with polyurethane foam

At present, thermal insulation of a wooden floor with polyurethane foam has become widespread. To perform this work, it is necessary to first prepare the base on which the ecowool will be applied, and spray the composition onto the lower surface of the floor. Step-by-step instruction as follows:

the coating is cleaned of contaminants and thoroughly degreased;
the base is dried to a moisture content of not more than five percent;
the high pressure unit is connected by hoses to containers with mixture components;
polyurethane foam spreads evenly over the floor surface;
the drying time of the coating occurs within two days from the moment of application.

It is quite possible to insulate wooden floors from below with polyurethane foam

High-pressure equipment used to spray polyurethane foam is very expensive. It is irrational to purchase it for arranging thermal insulation in a private house and it is better to rent this equipment.
