How to insulate floors in a private house without removing the old floor. How to insulate a concrete floor in a private house House on the thighs how to insulate floors

Each owner of his own home faces a very important task of insulating all premises. The article is intended so that each owner could understand how to insulate a wooden floor in a private house, as well as create comfort and coziness in the presence of any other basis for laying various layers in the "pie" of the floor.

Insulation of floors in a private house

Usually, private houses are located far from centralized coolant supply systems, so you have to take care of heating the premises on your own. Particular attention should be paid to floor slabs, which are the "Achilles' heel" of the house in terms of keeping warm. Therefore, it is necessary to take care of their insulation first.

In this case, you can use various materials and, depending on the choice, determine the method of their installation. Today, there are many ways to insulate floors, and many of them are modified directly by the owners who have shown their engineering talent. To understand how to properly insulate the floor in a private house, you need to familiarize yourself with the information presented below.

The main types of insulated floors

You need to decide on a method for insulating floors in a private house with your own hands. To do this, you need to know the material used to create them. The main varieties are represented by wooden floors, concrete base or dry screed construction.

Wooden floors

It is popular to use boardwalk and plywood flooring as wood flooring. There are two main types of such structures: one-layer and two-layer, under which the subfloor is located. Any types of wooden floors mean their laying on support beams that raise the coating to a considerable height above the poured screed, sub-floor or tamped soil. First of all, this concerns the processing of floors on the first floors when processing the foundation or soil. You need to know how to insulate the floor in a wooden house in order to take into account all the nuances in advance.

There are several main ways to insulate the floor in a private house with your own hands under a wooden flooring:

• when installing on a ground base, you can fill a layer of expanded clay under a wooden plank flooring;
• insulating material can be inserted into the cells between the support lags, or a self-expanding liquid composition can be poured;
• an infrared warm floor can be mounted on top of the boardwalk, on which the facing material will be laid;
• in the absence of a subfloor, it is necessary to use a vapor barrier film, spread on the crate from wooden beams... A layer of insulation is laid on top of it, and the material is selected with a minimum weight. It is best to use slabs or roll materials. A vapor barrier is again laid on top of this layer and covered with a boardwalk. It also does not hurt to know how to make a warm floor in a wooden house using modern materials and devices.

Concrete base

The floor is filled with concrete mortar, is very strong, reliable and durable, but its significant drawback is poor thermal insulation. The material itself is constantly cold, and therefore it is impossible to do without high-quality insulation. Unlike how a wooden floor is insulated in a private house, a concrete floor is the basis on which all layers will be laid, including insulation.

There are also several known methods for insulating concrete floors:

• a layer of expanded clay is poured onto it, on top of which a screed is poured;
• also, fine-grained expanded clay or grated foam can be poured into the mixture to create a screed to increase the thermal insulation characteristics of this layer;
• another layer of insulation is laid over the poured screed. For this, special bars are mounted in the gaps, between which the selected insulation material is laid. Next, a vapor barrier layer is laid, and from above it is closed with plywood or board flooring;
• the most the best option, of course, there will be installation of any of the known floor heating systems.

From a decorative point of view, a plywood and board coating does not look elite, and parquet or laminate laid on top of technical wood will look better in the photo and upon visual inspection.

Dry floor screed

Today in construction industry dry floor screed is gaining popularity. To create such a base, it is necessary to purchase a free-flowing composition for creating a dry screed. It may include fine-grained expanded clay, expanded perlite sand, etc.

Once the dry backfill layer is leveled, it can be covered with a technical layer of material, which will be the base for the cladding. Most often used for these purposes: chipboard, OSB, moisture-resistant plywood and other materials.

This design has excellent sound and heat insulation characteristics. It is very easy to install, and the structure allows the joint installation of various engineering communications... It is possible to improve the thermal characteristics of a room with such a screed by mounting any type of underfloor heating system.

The floor insulation itself is carried out according to a certain technology, based on what material was used to create the base for laying all the other layers.

Thermal insulation of wooden floors

This part will deal with how to insulate the floor in the old wooden house or at the stage of construction of a new building. You can start work with soil insulation (read also: ""). It is best to use a layer of expanded clay for this purpose. The embankment of material should be 0.2-0.4 meters thick, while it is leveled for high-quality laying of subsequent layers. The advantage of such a layer is that it blocks the penetration of cold into the premises, stopping it at the very base. However, this layer is not enough for high-quality thermal insulation of floors.

In this case, the insulation procedure is as follows:

• the subfloor is in perfect condition. For this, any defects are removed: cracks and holes are sealed with clay soaked in water to a creamy state. Clay can replace the putties familiar to builders. This natural material interacts well with wood and acts as a "excellent" sealant for board flooring;
• as soon as the applied clay mixture dries up, you can start laying insulation in the voids between the support logs. In this case, you can use: expanded clay, foam, mineral or ecowool, or polymer liquid insulation, presented in the form polyurethane foam;
• on top of the insulation, a vapor barrier layer of the film is laid, fixed on the logs and transverse fasteners between them;
• finally, you can start laying the boarding and installing the skirting boards.

Also, on the rough floor, special cells can be made, in which the insulation is laid.

Next, a layer of insulation is placed on the resulting structure and covered with a vapor barrier material. Plywood is used as a flooring, which, upon completion of installation, can be primed and varnished. Such a surface allows the laying of facing materials on it, as well as the installation of an infrared underfloor heating system.

Insulation of a concrete base

As mentioned above, concrete is a priori a cold material, which means that its warming should not even be discussed.

You can implement the laying of the material as follows:

• first rough concrete base covered with a waterproofing film, over which a 10-15 cm layer of expanded clay is poured. It is best to pour and level this insulation according to the pre-installed beacons (more: "");
• the prepared base is poured cement mortar liquid consistency to create a film on the expanded clay layer that protects against moisture loss from the main mortar to be poured under the screed;
• as soon as the improvised base dries up, a mesh for reinforcement is laid on it, and a screed is poured over it. It is best to use for these purposes a cement-sand mortar with the addition of crushed foam, which will enhance the thermal insulation characteristics of the layer;
• the selected coating is laid on the hardened screed.

However, in the coldest regions, such insulation is not enough and the owner should think about how you can additionally insulate the floor in a private house. In any case, for these purposes, it is necessary to process the joints of the base and walls of the room using waterproofing materialto create a 'trough' effect inside the room and minimize the risk of leakage of liquid components and common moisture.

If there is a waterproofing layer, you can proceed with the following actions:

• again, logs are mounted with an interval equal to the width of the stacked rolls or insulation boards. The height of the lags should also correspond to the proportions of the material being laid, and their thickness usually ranges from 7-9 centimeters;
• especially wide pieces of insulation are pre-cut to fit the required floor areas;
• it is worth remembering about the ventilation gaps between the first logs and the walls, which should be about 5 centimeters and are also filled with insulation;
• a vapor barrier material is laid on top of the laid heat-insulating layer;
• the end of the work is the creation of a plank or plywood flooring. On top of such a coating, any facing materials can be easily placed.

No less effective when insulating floors will be the idea of \u200b\u200blaying heated floors. If the owner does not want to think about the best way to insulate the floor in a private house, then a well-laid floor heating system will solve this problem.

Insulation of floors on a dry screed

A dry screed can act both as the main base for laying the floor covering, and as a heat-insulating layer over the existing concrete floor. However, many owners do not consider the thermal insulation characteristics of such a prefabricated structure to be good and therefore resort to additional insulation using a floor heating system.

On top of the screed, slabs are laid, covered with a waterproofing layer, on which the electric heating system will be located. It is impossible to refuse to use waterproofing, since liquid from the solution poured over the underfloor heating system can leak to the lower levels of the structure.

Accordingly, the finishing cladding is carried out over the frozen solution poured onto the heating system. As decorative cladding you can use any materials: tiles, linoleum, parquet, laminate, etc.

In the case of a dry screed, the use of a water-heated floor is impossible, since the heating circuit has a significant mass, and for its installation a significant deepening into the coating is required. If you lay it in a claydite layer, then the system will simply lose its effectiveness.

If the owner is not going to lay a massive cladding on top of a dry screed or create a self-leveling floor, then it is best to resort to using a thin film (infrared) warm floor. Consider further the implementation of all of the above types of floor heating systems.

Electric underfloor heating

The electric underfloor heating system itself is produced ready-made for installation. It is enough just to unfold it and lay it on a flat surface. A grid with a heating element is fixed on an adhesive mixture, which is usually used when installing tiles.

According to the standard, a sheet of electric underfloor heating has a length of up to 25 meters and a width ranging from 0.5 to 1.5 meters. Accordingly, before buying such a heating system, it is necessary to measure the room and determine the number of sheets required for high-quality heating (in more detail: ""). The advantage of this underfloor heating option is that it can be installed over a dry screed.

It is more difficult to use the option with a power cable as a heating element, since it is necessary to prepare a certain base for it with fasteners of appropriate dimensions. This method is more suitable for a cement-sand screed, in which it is easier to create appropriate fasteners.

Upon the installation of an electric underfloor heating, a thermostat is mounted in the room at a height of 0.5-0.7 meters from the floor, with which the owner will be able to control the used power of the system and adjust the heating level. This controller is connected with the laid cable, and the sleeve, which contains the floor part of the cable, must be under the tie.

The screed is poured over the installed and proven heating system. Its thickness should be at least 5 centimeters. It is possible to put the warm floor into operation no earlier than 1 month after the screed is filled, since this is the optimal period for the cement-sand mortar to harden.

Water heated floor

An underfloor heating system consists of a heating circuit that is properly installed on a selected base. For its assembly, pipes made of metal-plastic or polyethylene are used, laid on special mats or reinforcing mesh.

The step between parallel sections of the pipeline should be between 30 and 35 centimeters. Upon laying, all pipes must be brought out into a single collector cabinet, and a screed 10-12 centimeters thick is poured over the contour, taking into account the laid materials. On top of such a screed, any flooring.

It is best to lay the underfloor heating system on a layer of foil or any foil material, so that the generated heat energy is directed towards the room, and the floor does not become weak pointwhich causes heat loss.

Film (infrared) warm floors

Laying a film warm floor is not much different from using electric heating, and the same layers are laid under it: waterproofing and foil. Due to the lower degree of heating, the film should be located as close to the floor surface as possible.

It should be said that such a film in small sheet sizes is used as a substrate for mirrors, windows, etc. to eliminate the effect of fogging and icing. The electrical system can be used under the roof itself to remove snow and ice from the roof.

The main thing is that regardless of the type of heated floor chosen, the system is not visible in the photo and during visual inspection, which makes it an even more original heating tool. Many owners even refuse to use standard heating circuits, making their choice in favor of floor systems that cope with the heating task no worse.

Outcome

Insulation of floors in own home - this is not a complicated process, but it requires investment and some effort. It is important not to deviate from styling techniques in order to achieve maximum performance.

In case of certain difficulties, you can always ask for help from specialists who will take responsibility for all stages of work - from measurements and calculations, purchase necessary materials and components before laying each layer and putting underfloor heating into operation, followed by service if necessary.

After building a house, to keep warm, you will need floor insulation, especially when it comes to a wooden structure. It is necessary to prevent the penetration of cold coming from the ground, or from the basement. Before choosing technological process do-it-yourself floor insulation, you need to choose a material based on the characteristics of the base to be insulated.

Now on the market there are a lot of insulating materials for insulation, and every day high-tech ways to keep warm appear. To understand the best way to insulate the floor, consider the types of insulators.

The most popular are:

• styrofoam;
• expanded polystyrene;
• glass wool;
• expanded clay;
• mineral wool;
• penofol or isolone;
• cork insulation materials;
• ecowool, consisting of cellulose;
• fiberglass or gypsum fiber;
• "Termo Plast" - bulk material;
• foamed glass;
• stone wool;
• linen in mats;
• slag;
• polyurethane foam.

These insulators are categorized as synthetic and natural. Natural - ecowool, cork, sawdust, flax. The rest are synthetics.

Floor insulation material is divided into types:

• loose - sawdust, expanded clay, slag, foamed glass;
• jellied - polymer compositions applied by filling;
• sprayed - polyurethane;
• in the form of slabs - penoplex, mineral wool, linen in mats, gypsum fiber layers, glass wool, foam plastic, stone wool;
• roll - penofol, cork, isolon, flax, linoleum with an insulating layer.

The technology that will be used for thermal insulation directly depends on the type of insulation chosen. If expanded clay or penoplex is chosen as an insulator, then you will have to mount logs, or equip a screed.

Roll cork insulation, or izolon, can be simply rolled out over the surface and closed from above facing materialsuch as parquet, laminate, or rail car. As for linoleum with an insulating layer, then insulating material does not need to be laid under it, it itself is a good insulation.

If the height of the room is small, then it is better to use a bulk heat insulator, which will take a minimum of height. If we consider bulk or plate insulators, then it is worth remembering that they will occupy about 5-10 cm in height.

For a wooden house, it is mono to apply thermal insulation using a log, or on the ground, this makes it possible to use a thick slab or roll insulator. As for the apartment, it is better to use thin materials, since the ceiling height in apartments is usually 2.5 meters.

Before choosing a heat insulator, it is worth assessing the humidity of the room and measuring its height.

The higher the ceiling height, the wider the selection of insulators that can be used for floor insulation.

You can get one hundred percent insulation by using an electric underfloor heating in a duet with isolon, in this case you can regulate the temperature of the floor covering by switching the heating power.

How to properly insulate the floor, there are several methods of insulation that are used to insulate the floor, depending on the type of base - it can be wood, soil and concrete.

Insulation of the floor on the ground

When building a house, many private developers save on insulation by flooding concrete screed directly on the ground, and this is not entirely correct. Firstly, the earth can freeze in winter, and the concrete pavement will be cold, and secondly, the screed will not only contact the ground, but also be exposed to bottom waters, which will quickly disable it. Therefore, it is important to carry out high-quality waterproofing and floor insulation on the ground.

It is advisable to carry out floor insulation along the ground only if the bottom waters are at a sufficient depth from the surface. Otherwise, it is better to install beams and a double floor with insulation.

Floor insulation on the ground is carried out during construction, the finished coating will have to be disassembled, which will lead to a waste of additional funds. The floor cake begins to form after the foundation of the building is completely dry. It should be noted that the latter structure should rise 20 cm above the ground.

Several layers should be arranged:

• directly the ground;
• coarse river sand for leveling the plane;
• waterproofing layer;
• thermal insulation material;
• mesh, chain-link, for reinforcement;
• screed.

The first option for insulation

How to properly insulate the floor on the ground, we will consider in detail:

• The soil under the house, you need to level, remove debris and weeds, fill in the grooves and compact the entire surface well.
• Fill the entire plane with river sand, you can mix it with rubble, to a height of more than 5 cm.If a decision is made to insulate the floors with expanded clay, then it can be filled directly on the ground, but the cost of such floor insulation will be much more expensive. The sand needs to be leveled with a rule and tamped well.
• Lay a layer of waterproofing, for this you can apply:
  • membrane material based on polymer;
  • roofing material;
  • polyethylene film 200 microns, in two additions - the cheapest option for waterproofing.
• After that, you can start laying the slab heat-insulating material - it can be expanded polystyrene, or polystyrene.
• Then you can start pouring the finishing screed, just before that, lay the reinforcing mesh.

The second option for insulation

Better quality, although it will cost more, for this they equip a rough screed, on which a waterproofer is laid - in order to save money - a plastic film. It must be pressed with bars to the foundation, while the material should go on the walls by no less than 15 cm. The insulated floor in this way has very good thermal insulation characteristics.

As soon as the waterproofing is ready, the insulation is laid, for example:

• penoplex;
• expanded clay;
• styrofoam.

These are cheap types, but they are good heat insulators.

How to insulate a floor in a wooden building?

At the stage of building a house, the process of floor insulation begins. First of all, the place under the floor is covered with sand 5-6 cm, then expanded clay is poured onto it.

When choosing a heater, you need to take into account many points, for example, if you opt for natural materials, then it is worth remembering that they are subject to combustion, while they rarely resist moisture, and various microorganisms and rodents can start in them.

Often, sawdust is used to insulate the base, cellulose - processed for fire safety.

As for plate heaters, the following are considered in demand and of high quality:

• mineral wool;
• expanded polystyrene;
• glass wool;
• dry screed.

The finishing floor is mounted on logs, and a heater is installed in the intervals. The finishing coat can be installed over the screed. The screed is additionally insulated with expanded clay.

How to insulate the floor along the logs? For this, the structure is assembled with a step of 40-60 cm, while the subfloor must be well waterproofed from below. A vapor barrier is placed on top of the boards and logs. After that, insulating is placed in the gaps, slab material, the width of the slabs is just 60 cm, and they are covered with a finishing coating - plywood, OSB or a board.

If during construction it is decided to fill in a rough screed, then it is better to perform it using expanded clay. This will give the effect of additional thermal insulation of the floor. Then logs are arranged on top of the screed, on top of which the finishing floor will be laid, under which there will be a layer of heat-shielding material. Thanks to this cake, the result is a perfect floor insulation.

If the floor in the house is wooden, then a dry screed on the floor is well suited as insulation. To equip such insulation, you need to fill in expanded clay along the guides set at the level. Then a gypsum fiber insulation plate is laid on the expanded clay. This method is simple, but not applicable in high humidity.

Not so long ago, a practical, durable and fireproof material appeared on the market - foam glass. The thickness of this material reaches 12 cm. These slabs can be laid not only on a wooden floor, but also on a concrete one.

How to insulate a concrete floor

The concrete floor can be insulated with the following materials:

• expanded polystyrene;
• styrofoam;
• ecowool;
• liquid insulation;
• mineral wool.

But this heat insulator will take away precious centimeters from the height of the room, since logs need to be mounted on top of the base, on top of which plywood or OSB will have to be laid, and only then the final floor covering. At the same time, this is a very labor-intensive process and very expensive.

You can equip the screed by combining it with expanded polystyrene. At the same time, pipes for a warm floor can be built into the screed - the thickness of the coating will be more than 10 cm.

You can arrange a cake from expanded clay and gypsum plasterboard, then the thickness of the thermal insulation will be 7 centimeters. If the base is initially even, then only gypsum fiber sheets can be used, while the thickness of the insulation will be only 2 cm.When insulating the floor in an apartment with not very high ceilings, it is not advisable to choose thick insulation, since the useful space for life will decrease.

If the floor in the apartment requires insulation, then it is better to use Isolon, followed by the arrangement of a warm, infrared, electric floor. This option will not reduce the height, and will make living in the apartment more comfortable, due to the fact that the floor temperature can be regulated.

The most effective option for high ceilings is the arrangement of a water heated floor. The height of the cover in this case will be 10-12 cm.

To save space, you can use a screed with an insulating effect. This is enough new material, but has already established itself as high quality and reliable. In this case, the insulation layer will be only 3 cm.

You can use the simplest and most common method - double decking. Planks 2.5 cm thick are fixed directly on the concrete base with tongue-and-groove piles. After that, a substrate and a laminate or linoleum with an insulating layer are laid on the wooden base.

Linoleum on a substrate is often applied directly to a concrete base, while the thermal insulation properties are quite good.

Fiberglass, or wood can be laid on top of this insulation. Some ordinary people directly on polyurethane foam, in order to save money, lay a clean floor covering.

In custody

Indoor floor insulation - each master has his own way. Some people prefer time-tested materials, equipping them with a thermal insulation "pie". Some people prefer innovative heat insulators. But the main factor when choosing a material is the cost and quality of floor insulation.

In any structure, the floor, as a rule, is the most problematic part, since the penetration of cold air masses through it with well-insulated walls is quite likely. Neither an excellent heating system nor carpets will help solve the problem. Wood floors are more vulnerable than others.

The most logical solution would be proper insulation floor with the help of special materials, but first of all it is worth studying the structural features of the wooden flooring.

Features:

Even correct styling floorboards without gaps and gaps disappear over time due to the peculiarities of the wood structure. Boards can dry out and heat loss is inevitable. Up to 30% of the heat escapes through the unreconstructed floor, therefore it is necessary to insulate the wooden floor, but it is worth remembering the features of this work.

The wooden floor does not consist of only planks, it has a more complex structure. The base of the floor is logs, which are wooden blocks. Either a subfloor is attached to them, consisting of untreated boards, plywood, chipboard, and which is the basis for finishing coatings (laminate, parquet), or a finishing floor, the basis of which is made up of boards processed by a cutter.

To make the floor comfortable, they use different kinds insulation, but for normal operation one insulation is not enough - it is necessary to use layers of waterproofing.

Their presence is necessary, since excessive humidity in the space contributes to the formation of fungi and the development of insects that destroy the wooden structure.

Insulated premises

Most often, wooden floors are found in private buildings, and therefore it is important to know how to insulate a wooden floor in a country house. And this depends on many factors. First of all, this is the time of the construction of the structure. If the house is new, then you need to wait for the time it takes for the wood structure to shrink (6-7 months). If the house is old, then after dismantling the old coatings, be sure to pay attention to the wear and tear of the lag, removing the rotten, even partially, logs.

When choosing a material for thermal insulation in a country house, it is necessary to take into account the area of \u200b\u200bthe room and the height of the ceiling, the type of surface, the option for placing the floor structure, the temperature and humidity of the room, the load, and, of course, the purpose of the house. Each of these factors directly affects the choice of material.

The height of the ceiling in a country house for efficient and economical heating should be between 2.35-2.50 m. The height of the room after laying the insulation should not be less than 2.35 m, otherwise the space will not be very comfortable, and higher than 2.5 m in order to avoid increasing heating costs.

The thickness of the insulation also depends on the purpose of the house. For houses used in summer period, you can get by with an insulation 5 cm thick, and for a house that will be used constantly, it is better to purchase material with a thickness of at least 20 cm.

The choice of material is directly related to the construction of the floor, as it affects the installation method. There are several types of flooring:

• The flooring was laid either at a short distance from the ground, or on a special bedding. Both the flooring was laid without ventilation.
• The flooring is located above a basement or cellar with high humidity.
• The flooring is located on the joists, below there is a pile foundation with a grid.
• Laying the flooring on the joists, at the bottom there is a ventilated basement with good air ventilation due to the presence of vents.

When choosing a material for a country house, it is necessary to take into account the characteristics of the insulation itself. Besides the thickness, great importance have characteristics such as environmental safety, resistance to fire, insulation service life.

To insulate the floor in a toilet located in a private wooden building, it is worth not only taking into account the above characteristics of the insulation, but also taking care of waterproofing the underground space of this room, as well as thinking over a ventilation system.

You can also insulate wooden floors in an apartment. The choice of material and installation method will depend on the floor of the apartment. For the first floor, where the ground or basement is located nearby, the insulation will be both from the side of the apartment and from the side of the basement, if any. For floor insulation on the 2nd, 3rd, 4th or 5th floor, the material is laid only from the side of the apartment.

In a private house, floor insulation on the 2nd floor makes sense only if one or the other floor is not heated, or when building the first floor, warmer materials were used compared to the second, as a result of which a temperature difference arises.

Floor device

Floor insulation can be done using different methods. The choice of method depends on the initial state of the coatings, the location or absence of ancillary facilities.

The simplest, most reliable and most often used method is the lag insulation. It is suitable for insulating floors both for private wooden structures and for floors located in apartments located on the 1st floor. In this case, the principle applies, in which the coating is divided into finishing and rough.

Thermal insulation of a wooden floor occurs due to the sequential laying of various materials.

The draft layer consists of wooden boardsdocked with lags. At the bottom of the boards are the cranial bars that run along each log. The logs themselves are bars that are laid over the entire surface of the floor at a certain distance from each other, as a rule, from 0.6 to 1 meter. They can be attached to the foundation of a building, be cut into the basement of a structure, and attached to load-bearing beams or fixed on erected posts made of durable material (brick, concrete, stone).

The vapor barrier layer is laid on the subfloor and on top of the log. It is only needed when using a certain type of insulation, and the insulation itself is placed between the log. The gap between the insulation and the vapor barrier layer should be at least 4-5 cm. This value ensures proper ventilation of the space. If there is a lack of height, counterrails are packed on the logs.

If the building is located in an area where high groundwater is present, then instead of a vapor barrier layer, you need to lay a waterproofing layer that will prevent the insulation from getting wet. In addition, some types of insulation do not need a vapor barrier.

The installation outside the house of special air ducts installed in 4-5 m increments and an exhaust pipe will also help get rid of high humidity. The presence of these elements promotes good air circulation and increases the efficiency of floor insulation.

It is possible to insulate a wooden floor without dismantling the old coating using linoleum on a jute or felt basis, but it is better to use it not as independent view insulation, but as an addition to warm floor... This durable and easy-to-install coating performs the function of waterproofing.

Another method of insulation without dismantling is liquid foam, which is driven under the floor through the holes with a special device. But, using this method, it is worth remembering that the filling of the space is uneven, and therefore this option is not perfect.

How to choose the right insulation

All types of materials of natural or artificial origin used to insulate a wooden floor, are subdivided into:

• fibrous;
• foamed;
• filling;
• cellular stone.

Any insulation has both advantages and disadvantages.

The most common and affordable material is mineral wool. Floor insulation with mineral wool has a lot of advantages. This material, in addition to its direct purpose, has very high noise insulation properties, has good fire resistance, and has a low thermal conductivity. This eco-friendly material is easy to arrange and has different shapes release (rolls, mats), which is important to consider when choosing.

A type of mineral wool is a brand insulation Isovermanufactured by Finnish manufacturers for over 20 years. The basis of this material is fiberglass. Insulation "Izoverom" will protect the wooden structure from the development of fungi, bacteria, invasion of rodents and insects.

But this material has its drawbacks. First of all, they include poor moisture resistance, therefore, it is better to use mineral wool in combination with a waterproofing layer.

Unlike mineral wool, foam is poorly permeable to water. This lightweight, non-toxic material is not subject to deformation due to temperature extremes. Even having a small thickness, it does not lose its good thermal insulation properties. But it also has some disadvantages. The fragility of the material is in the first place, so the material must be adjusted as accurately as possible.

Durable polystyrene foam has improved characteristics. In addition to high levels of noise insulation and low thermal conductivity, the material is distinguished by increased strength. Installation with extruded polystyrene foam, in addition to insulation, will protect the house from the invasion of rodents and the development of mold fungi.

Vapor-proof roll materials izolon or penofol have a small thickness, and therefore cannot provide the required degree of insulation. Most often, these materials are used in conjunction with others. With penofol or izolon, a rough floor surface is laid, using it as a waterproofing layer, on which insulation is laid.

Bulk materials used as insulation, such as expanded clay and sawdust, are used for structures without basements.

Insulation of the floor with sawdust makes it possible to save money, since sawdust is of low cost. In addition, the shape of this insulation allows you to fall asleep even the most hard to reach places... Very often sawdust is combined with other substances to enhance thermal insulation, antiseptic and other properties.

Expanded clay floor is insulated in the case of close proximity to the ground. This lightweight material has a porous structure, due to which, in addition to thermal insulation, good sound insulation is provided. He is not afraid of temperature changes, and even an inexperienced person can handle the installation.

Insulation technology

After analyzing the floor structure, it is necessary to consider the best solutions for a particular room. There is a certain sequence of floor insulation, suitable both for insulation along the logs, and without them.

First, you need to dismantle the old coating, if the insulation process takes place in the old room, and install or replace the logs. Then proceed with the laying of the rough covering, on which the waterproofing or vapor barrier layer is laid. Its edges should overlap the walls by 15-20 cm, and the joints should be glued with tape.

Today, when arranging a private house, the floor is increasingly made of wood. This is due to the fact that wood has excellent thermal insulation properties. But at the same time, he is still not able to withstand the cold air that rushes into the house from underground. Thus, living in such a house is uncomfortable, and it also leads to a decrease in its service life due to the accumulation of condensate in the underground. To solve all these problems, it is necessary to carry out floor insulation in a private house.

Applicable materials

Expanded clay and sawdust

These materials are considered the most affordable today in terms of cost and ease of installation. The insulation process is carried out by filling the material between the previously laid logs. It is sawdust that is most often used for floor insulation in a private house, since it is an environmentally friendly material. Although it has its drawbacks - it is exposure to rodents.

Sawdust for wood floor insulation

Mineral wool

This heat insulator is also in high demand, but in comparison with sawdust, it contains chemical compounds. So for those who care about the environmental factor, you need to look at another option. If the thermal insulation work will take place in a room with a high level of humidity, then before laying the mineral wool, you will have to take care of installing a waterproofing layer. This is extremely important, because when water penetrates the mineral wool, it will lose its heat-insulating qualities.

Mineral wool for insulation

The advantages of mineral wool include:

• fire resistance;
• resistance to biological and chemical influences;
• excellent heat and sound insulating qualities.

Mineral wool is produced in slab format, while one surface is harder than the other. It is indicated by a blue stripe. When insulating, it is important to take this into account and lay the heat insulator with the hardest side up. The layer thickness is 200 mm.

Izolon

Mineral fibers are also used in the manufacture of this material. But in comparison with the previous insulation, it is accompanied by a higher hydrophobic ability and low heat conductivity. It is advisable to use Izolon for reliable thermal insulation of old wooden floors.

Izolon for insulation

Rockwool insulation remains one of the most popular types of isolon. It is characterized by similar properties to isolon, but only in the composition there is basalt wool, thanks to it a high coefficient of sound insulation is achieved. The thickness of the layer to be mounted is 2-10 mm. But how the floor is insulated in a wooden house from below with isolon, you can read

Expanded polystyrene

Plywood

Currently, plywood can be produced in several grades, including:

They all differ among themselves by such a criterion as the level of moisture resistance. But this level is due to such indicators:

• type of glue used;
• the type of coating that is applied to the top layer of each sheet.

FSF plywood has the highest level of moisture resistance. But it is used most often in rooms with high humidity levels, unheated.

How to insulate from below

To create a reliable barrier against heat loss, you need to insulate the floor from below, adhering to the following plan:

Perform events from above

To insulate the floor from above, a high-quality, warm and thick substrate based on polypropylene or cork is required. On top of this material, the flooring is laid.

To get high-quality floor insulation in a private house, you need to take care of a new additional level. So fasten the logs in the floor, which were previously treated with an antiseptic. Mount the selected heat insulator between the lags. As a rule, they use mineral wool. Then cover the floor with plywood or chipboard, and on top of them, you can install any floor covering.

The only drawback of such coverage is the cost of money, time and effort. In addition, the height of the room will decrease as the floor becomes higher. And this is a direct path to raising thresholds and doors.

Activities to keep from rotting

If your task is to insulate the floor in order to prevent rotting, then it is important to choose the right material. For these purposes, a heat insulator with an increased level of moisture resistance is used.

Heat insulator with an increased level of moisture resistance

Insulation materials such as expanded clay and expanded polystyrene remain the highest quality in this regard. The first has a ceramic shell that does not absorb moisture and has low heat conductivity. Styrofoam has similar qualities.

Features of warming an old house

Most often, expanded clay is used as a heater for the floor in a private house, since it has excellent moisture resistance and thermal insulation. To carry out thermal insulation work in an old house, you must adhere to the following instructions:

1. Dismantle the old flooring and fasteners.
2. Fill, level and tamp the sand cushion. The layer thickness will be from 100 mm.
3. Install a waterproofing layer using dense polyethylene.
4. Bring the level to the floor and to the plaster solution. Place guide beacons. When the mixture becomes solid, and the level is finally set, then you can proceed to laying the heat insulator. The layer thickness must be over 100 mm.
5. Treat the waterproofing with a mixture of cement and water. Thanks to this, all subsequent work will be easier.
6. Reinforcement of the floor is a necessary work, due to which it is possible to minimize deformations leading to the destruction of the screed.
7. The filling is done carefully and accurately, otherwise you will have to deal with leveling the floor.
8. The poured floor will fully harden after 28 days. But it will be possible to walk on the surface in 7 days.

Features of warming houses on a pile foundation

Before starting thermal insulation work, it is necessary to carefully prepare the surface, removing all debris. Now it is fashionable to proceed to the installation of the lag on the base on both sides. Go through with an antiseptic. At the same time, make sure that the floorboard must touch all lags, without exception. But the fasteners of the lags themselves should be performed from two sides along the corner for each.

Upon completion of these works, you can proceed to the arrangement of the rough floor layer. It serves to make it possible to lay the heat insulator between the lags. To obtain a rough coating, it is worth using an edged board with a section of 100x25 cm.

First you need to screw the bars 5x5 cm from the bottom and across the log. Divide the space into several zones. Attach the boards to the wind and moisture protection membrane. This will create reliable protection from moisture, which is formed due to a sharp temperature drop. You can try to apply

On the video of floor insulation of a house on a pile foundation:

Fasten the membrane with a step of 20-25 cm between the lags. In this case, you must definitely go to them. Now you can proceed to the direct installation of the insulation itself. This should be done in 3 layers. At the end, cover everything with a membrane and lay a finishing floor.

Work with the wooden floor in the bath

During construction modern baths perform the foundation. This suggests that there is a need for the arrangement of the rough and final floor. The process of installing the finished floor is performed with a slope towards the drain. It is laid on logs with a gap of 3 cm at the walls.

Be sure to lay a layer of vapor barrier membrane. The waterproofing layer must be on the entire surface of the subfloor. The laying is carried out with an overlap, and the fastening is done with adhesive tape.

After that, you can lay the insulation. It is best to use expanded polystyrene. It does not absorb moisture, which is important for a room with a high level of moisture. Heat insulator plates are mounted between the logs so that there is a 2 cm ventilation gap on top. It is also worth familiarizing yourself with information on how to use and which one to use for the walls of the house outside for siding.
