Which material is better to choose for internal insulation walls country house— we’ll figure it out in this article.

Criteria for choosing insulation for a country house

  • Thermal conductivity. The lower the thermal conductivity of the insulation, the more efficiently it will be maintained temperature regime inside the building: it will remain warm or cool.
  • Resistance to negative temperatures. If the dacha is not heated in winter, the temperature in its interior is often below zero, which can lead to the destruction of some types of thermal insulation.
  • Easy to install. Most dacha owners prefer to furnish their home with their own hands, so ease of installation of insulation is of considerable importance.
  • Price. A dacha, as a rule, is a house for temporary residence, for this reason many people prefer budget types of insulation.

Tip 1. Be sure to take into account what material the house is built from. If for wooden buildings the air permeability of the heat insulator is fundamentally important, then for buildings made of brick or foam concrete this parameter is not so critical.

Tip 2. Moisture resistance of a building material is an important criterion for selection suitable thermal insulation for walls in the country house. Consider whether the building will be heated in winter. The likelihood of condensation forming due to the difference in temperature outside and in the house depends on this, which will subsequently contribute to the soaking of the insulating layer, and it will quickly collapse and lose its functionality.

This problem can be avoided if you use a special vapor barrier film to protect the insulation from moisture.


Choosing a material for insulating the walls of a country house from the inside

Let's look at the advantages and disadvantages of the most popular insulation materials for summer cottages.

Mineral wool

Mineral wool is an inorganic fiber made from porphyrite. This material can be used to insulate a summer house, provided that the walls of the house are additionally sheathed with wood, plasterboard or plastic. Mineral wool is also well suited for wooden frame structures.

Advantages:

  • Resistance to temperature changes. Mineral wool perfectly insulates any premises and buildings in heat and sound.
  • Elasticity. Due to the high level of resistance to temperature changes, it practically does not change its structure and shape.
  • Strength. This property allows you to successfully use it for insulating the walls of buildings.
  • Non-flammability. Guarantees the safety of the building, since this material is practically not subject to ignition.
  • Does not require special skills to operate.

Flaws:

  • Fragility, complicating installation.
  • Hygroscopicity- mineral wool absorbs moisture and may lose its original properties.
  • Price- above average, in comparison with other materials.

Ecowool

Ecowool - the most environmentally friendly pure material among all types of insulation. Made from recycled cellulose, applied to walls by spraying and has a thermal conductivity of 0.038 W/mK.

Advantages

Having excellent air permeability, ecowool also actively absorbs moisture, but also dries quickly without changing the thermal insulation parameters.

Ecowool is impregnated with special additives, making it fire-resistant and biologically inert.

Flaws

The disadvantages of this insulation include its considerable cost, both in purchase and in installation, which requires certain skills and equipment.


Expanded polystyrene

Extruded polystyrene foam is one of the most popular types of insulation among dacha owners. This material belongs to the middle price category and is characterized by thermal conductivity from 0.032 to 0.044 W/mK.

Advantages

High strength, moisture resistance, ease of installation are the key advantages of expanded polystyrene as insulation for the walls of country houses.

Flaws

Disadvantages include poor air permeability, poor adhesion to the cladding, non-environmental friendliness and toxicity in case of ignition.

Well suited for insulating the walls of one-story buildings, including country cottages.


Styrofoam

Polystyrene foam is the most inexpensive type thermal insulation material, characterized by high moisture resistance, low thermal conductivity of the order of 0.037 W/mK and a service life of about 25 years.

Advantages

The advantages of polystyrene foam also include its immunity to microorganisms (fungus, moss, rot), ease of installation due to its low weight, compressive and bending strength.

Flaws

However, polystyrene foam does not withstand pinpoint impacts well and is a material with poor breathability and high toxicity upon fire. Polystyrene foam is not recommended for insulation of wooden houses, but for thermal insulation brick walls it can be used successfully.

Tip 1. When insulating the walls of a house from the inside, keep in mind that the inner layer of insulation will “eat” usable area, therefore it is more expedient to insulate small summer houses from the outside.

Greetings. This time you will learn how to properly insulate a country house. As an example, consider popular methods of thermal insulation wooden dachas and construction projects made of concrete blocks. The types of buildings for review were not chosen by chance, since most of the dachas were built from these materials.

I am sure that the methods proposed in the article will be of interest to owners of old country houses. However, if your dacha is new, but not warm enough, you will also find a lot of useful information for yourself.

Basic information about insulating country houses

Correct thermal insulation country house begins with heat loss analysis using special equipment - a thermal imager

Insulating a country house has the following goals:

  • Ensuring living comfort;
  • Reducing heating-related costs;
  • Ensuring a long service life of the facility without the need for regular repairs.

From the above points we can draw the following conclusion - the cottage must be energy efficient.

What's happened energy efficient house? This is a construction project in which, thanks to high-quality thermal insulation, an optimal microclimate is combined with low energy consumption.

In accordance with SanPiN 2.1.2.100200, the following requirements are imposed on the microclimate of residential premises during the cold season:

  • the average air temperature should be from 18 °C to 24 °C;
  • relative air humidity – within 35-40%;
  • air flow speed no more than 0.15 m/s.
  • the surface temperature of the walls is no more than 4 °C lower than the air temperature in the room;
  • the floor surface temperature is no more than 2 °C lower than the air temperature in the room.

Do you think the microclimate within the walls of your dacha meets the listed requirements? If it doesn’t match, then it’s time to insulate it country house.

Instructions for insulating a dacha depend on the following factors:

  • Nature of operation of the facility (seasonal or all-season);
  • Materials used in construction;
  • Type of glazing of the object;
  • Presence of technological errors made during design and/or construction;
  • Type and efficiency of the heating system used;
  • The budget of funds allocated for the implementation of the project.

Thermal insulation of a construction project can affect individual structural elements, for example, floor walls or foundations, or can be carried out comprehensively. Despite the fact that the price of complex insulation is significantly higher than the cost of separately performed work, it is an integrated approach that provides the best result.

Insulation of a wooden house

Wooden cottages are insulated in such a way that the lumber retains an optimal degree of humidity and does not rot or collapse. Conventionally, the thermal insulation of a wooden cottage can be external and internal. Which of these varieties is more preferable?

External (external) insulation of walls prevents them from freezing. In addition, the dew point shifts towards the outer edge of the wall. In order to reduce the formation of condensation, a ventilated façade is installed. As a result, the wood remains dry and does not rot, which has a beneficial effect on the resource of the house.

Thermal insulation load-bearing walls from the inside of the house reduces the usable area of ​​the room, which is especially noticeable if the dacha is small. In addition, by insulating the inner surface of the walls, you will cause the wood to freeze in winter and get wet with the onset of the warm season. As a result, the wood will rot and rapidly deteriorate.

The following conclusion can be drawn: we do internal thermal insulation of a wooden building only in combination with external insulation. As a last resort, we limit ourselves to external insulation only.

Thermal insulation of wooden walls

One of the most correct instructions Insulation of wooden walls involves the construction of a ventilated facade with the laying of heat-insulating material. The advantage of this solution is the absence of condensation and the ability to use thick insulating materials.

For execution installation work The following materials will be required:

  • Guide metal profiles 100×40 mm;
  • Vapor barrier film;
  • Slabs of dense mineral wool (thickness similar to the width of the metal profile or will have to be laid in two layers);
  • Double-sided tape;
  • Windproof coating;
  • Wooden blocks 50×20 mm;
  • Vinyl siding.

The instructions for installing a ventilated facade with insulation are as follows:

  • Using a plumb line and a spirit level, the curvature of the walls was determined;

In our case, the attic protrudes slightly forward relative to the first floor.

  • At intervals of 60 cm from each other, leveling pads made of pieces of plywood were fixed to the surface of the walls in order to compensate for differences in levels;

  • Vapor barrier strips were secured with a stapler along the surface of the wall;

The vapor barrier has 2 sides - one smooth, the other rough. We direct the smooth side outward, and the rough side inward. We attach the vapor barrier horizontally, so that the upper strip overlaps the lower strip and thus ensures condensate drainage.

  • Guide profiles were vertically fixed on top of the vapor barrier;

The profiles are installed on leveling plywood pads, which can be easily felt under the vapor barrier layer. As a result, the guides should be spaced 60 cm apart from each other.

  • We insert mineral wool slabs into the spaces between the guides;

  • We glue pieces of double-sided tape along the outside of the guides;
  • We lay out a windproof covering, temporarily fixing it with double-sided tape;

  • On top of the windproof covering we fill a sheathing of wooden slats;

We fasten the lathing so that the slats are fixed on the metal guides that were used in the manufacture of the supporting frame.

Are there other ways to insulate wooden walls?

Due to the ease of implementation, spraying polyurethane foam is becoming increasingly popular. A two-component mixture is sprayed onto the wall under pressure, after which it polymerizes and forms a layer of foam. Despite the obvious advantages, the method has a significant drawback - the equipment for spraying is expensive, and therefore it will not be possible to perform such insulation with your own hands.

Foamed polyurethane is an airtight composition that will not allow the wood to breathe. Therefore, there is a possibility that the walls on the outside will rot and collapse.

Thermal insulation of floors and ceilings in a wooden house

Floor insulation in wooden house can be done using various materials. For example, I recommend laying expanded clay backfill, mineral wool or crushed foam between the lags.

But the method of floor insulation you choose must meet the following requirements:

  • Structural floor elements, including joists and planks, must not rot;
  • Filling the space between joists should be unattractive to rodents;
  • The thermal insulation layer must be fireproof and non-toxic.

As an example, I offer instructions correct device thermally insulated floor pie.

The easiest way to insulate the floor on the joists is during the construction of the cottage. If insulation is carried out in a house that is already in use, the flooring will have to be completely removed.

After access to the joists is open, you need to cover the wooden parts with antiseptic and fire retardant in several layers, with a break for each previous layer to dry.

After the impregnation has completely dried, the space between the joists is lined with a windproof coating. This measure will eliminate the possibility of the formation of cold bridges. Wind protection in mandatory fastened to the joists with brackets made of construction stapler.

Insulating material is laid or filled into the prepared space between the joists.

Traditionally, mineral wool is used as insulation. But such material, over time, can become a refuge for rodents. Therefore, I recommend using dense expanded clay backfill with a core diameter of 3-5 mm. This backfill is produced by the Knauf company for the installation of dry screeds.

After the insulation material has been laid between the joists, a top layer of vapor barrier is laid. Vapor barrier strips, as well as wind protection, must be laid with an overlap so that there are no gaps. A boardwalk is installed on top of the finished pie.

Floor insulation is performed in the same way as floor insulation. But for these purposes, lightweight materials are used, mainly mineral wool or polystyrene foam boards.

When arranging ceilings, a vapor barrier is placed at the bottom of the cake in order to prevent the penetration of damp warm air from the premises.

A windbreak is laid over the insulation cake to act as a barrier to cold air from the attic.

Insulation of a country house made of aerated concrete or silicate blocks

Unlike wooden cottages, objects made of brick or lightweight concrete can be thermally insulated both outside and inside. And in this case, external insulation is an order of magnitude more effective than internal insulation.

But the best results are guaranteed by comprehensive insulation, during which the thermal conductivity of walls, blind areas, floors, ceilings and roofing systems is reduced.

Thermal insulation of walls

For thermal insulation of walls made of bricks, concrete blocks and similar building materials you can use cellular polystyrene plates; mineral wool, application of polyurethane foam.

Affordable price is a good reason to buy polystyrene foam boards

Of the listed materials, I especially recommend polystyrene foam boards. Using this type of insulating materials, you can not only reduce the thermal conductivity of load-bearing walls, but also subsequently plaster the building, giving the facade an attractive appearance.

Installation of polystyrene foam boards followed by plastering is carried out in accordance with the following diagram.

To install thermal insulation, you will need the following materials:

  • Cellular polystyrene slabs with a thickness of 150-200 mm (thickness is selected depending on climatic conditions region);

  • Disc-shaped dowels (umbrellas) in the amount of 4-5 pieces per slab;
  • Starting strip - a profile for holding the slabs of the first row in the required position;
  • Alkali-resistant reinforcing fiberglass mesh;
  • Tile adhesive or special adhesive for polystyrene foam;
  • Plaster mixture or tile adhesive to make a reinforcing layer;
  • Plaster mixture for finishing.

Instructions for wall insulation modern dacha from aerated concrete blocks or sand-lime bricks the following:

  • Scaffolding is assembled, from which it is easier and safer to work than from a stepladder;
  • Using a chisel, the sagging of masonry mortar is knocked off the surface of the walls;

  • The surface is primed with one layer of penetrating primer to strengthen the porous base, and one layer of film-forming primer for better adhesion;

You can apply the primer with a roller or even a brush. But, given the large surface area and application in two layers, I recommend using a spray bottle to work with the primer.

  • At the level, along the edges of the wall, orientation cords are fixed along which the insulation slab will be laid;

  • Using a laser level or a spirit level with a plumb line, the location of the upper part of the slabs in the first row is determined and the corresponding mark is set along the perimeter of the walls;

  • Mix the adhesive solution in accordance with the manufacturer's instructions and, after preparation, leave for 5 minutes;
  • Apply glue to the plate;

  • We install the first slab from the corner, so that its edge protrudes beyond the corner at a distance equal to the thickness of the slab;

  • The second slab is placed from the corner close to the aligning edge of the first slab, as shown in the figure;
  • In a similar way, the entire first row is laid out along the perimeter of the walls;
  • When laying each row, we check the horizontal and vertical position of the slabs with a level;

  • We begin laying the second row also from the corner. The slabs should lie in relation to each other with an offset, as shown in the figure;
  • We lay the third row offset relative to the second row, but so that it coincides with the slabs in the first row;

  • The next rows are installed in a similar way, so that as a result a jagged joint is formed at the corner;

  • We combine the slabs with the window openings, cutting the foam, as shown in the figure;

  • If during installation there are gaps between some slabs, immediately fill them with polyurethane foam to prevent the formation of cold bridges;
  • After the foam has dried, remove the excess with a sharp knife;

  • Disc-shaped dowels are installed along the edges and in the center of the slab, so that their caps are recessed into the surface of the foam;

  • The slopes are strengthened with reinforcing fiberglass mesh and plaster mixture;
  • The recesses for the dowels are filled with the mixture;

  • The wall cladding is reinforced with fiberglass mesh and plaster mixture;

  • Decorative plaster can be applied on top of the dried base layer.

Floor insulation

In previous instructions I talked about how the floor is insulated wooden joists. This technique can also be applied to brick houses, where the floors are laid on joists. But what to do if the house already has a ready-made concrete screed?

I offer the following options:

  • Installation of micro-lags followed by laying thermal insulation and laying plywood;
  • Installation of a dry screed made of gypsum fiber board with expanded clay backfill;
  • Laying an additional layer of expanded clay concrete;
  • Laying an additional layer of polystyrene concrete;
  • Installation of underfloor heating systems for subsequent use as an auxiliary heating system.

If the level of the subfloor allows you to raise the surface by 5-10 cm, I recommend laying a layer of expanded clay concrete along the beacons. The advantage of this solution is the low thermal conductivity and high strength of the material. Again, laying expanded clay concrete is much easier and faster than working with ordinary concrete, if only because the finished solution is much lighter.

For dachas, the problem of rodents, which gnaw holes in the insulation layer and feel comfortable in the underground, is an urgent problem. Expanded clay concrete, after gaining brand strength, is practically not inferior in hardness to heavy concrete, and rodents will not settle in such an underground.

Another option that I personally tried in my home is the installation of a “Warm Floor” system based on infrared film emitters. This option is preferable for summer cottages that are used seasonally. If you decide to live in country house, in winter it will be possible to quickly heat the floor, which means comfortable conditions temporary accommodation will be provided.

Film infrared floor is universal solution, which can be laid under tiles, under carpet or under laminate. The only one an important condition For uninterrupted operation of the film heater, a perfectly flat base without a pronounced microrelief is required.

Why don’t I recommend underfloor heating based on water heating equipment? Most dachas and country houses in the province do not have a stable water connection. Again, the wiring in an older home may not be able to handle the load of a water heater.

Conclusion

Now you know how external insulation of low-rise buildings is performed. I am sure that the proposed instructions and recommendations will be useful when arranging your dacha.

If you have any questions, ask them in the comments to what you read - I will definitely answer all of them. By the way, maybe you will find answers to your questions by watching the video in this article.

A dacha is a place where you can relax from the noisy city and enjoy clean air. Although the dacha is not used for permanent residence However, every owner wants it to be comfortable and cozy. It is better to think about the comfort of a dacha already at the stage of its construction. Or renovation work is being carried out.

The reasons for heat loss can be different. Heat usually escapes through surfaces that are poorly insulated. Consequently, not only the external part of the country house needs thermal insulation, but also the internal one. Therefore, in this article we will talk about insulation interior walls at home in the country. Which insulation to choose? How to directly insulate the inside of a house? Let's answer these questions.

Before choosing one or the other insulation material You need to pay attention to the following parameters:

  • Thermal conductivity level. The best option is a low level of thermal conductivity. Therefore, with a small thermal conductivity index, it remains optimal temperature indoors.
  • Level of resistance to low temperatures. If in winter season Since the country house is not heated, the temperature in it can drop below zero. This can lead to deformation of many types of insulation.
  • Simplicity in the installation process. Owners of summer cottages usually want to arrange it themselves. Therefore, the heat insulator should be installed with your own hands without any problems.
  • Price. Of course, quality is important, but still few people spend big cash for insulation of a house for temporary residence.

These factors are fundamental when choosing insulation material.

Let's consider literally two tips:

  • The material from which your country house is built is most important factor. You need to pay attention to it. For example, for houses built of wood, a thermal insulator is needed that has excellent air permeability. For houses built of brick, this criterion is not particularly important.
  • The level of moisture resistance is also the most important parameter that you should pay attention to when choosing insulation for the internal walls of a country house. Ask yourself: will my home be heated during the winter season? This factor determines whether condensation will form due to big difference temperatures (indoors and outdoors). Condensation can cause the thermal insulation layer to become wet; it will deform in a short period and lose its properties. specifications.

But this problem can be easily eliminated if you use a specially designed vapor barrier film, which will protect the heat insulator from the harmful effects of moisture.

Which ones exist? construction products For ?

Selection of thermal insulation material

Let's consider the most popular insulation products in detail.

Use of mineral wool

Mineral wool is an inorganic fiber made from porphyrite. This thermal insulation product can only be used under one condition. If the surface of the walls is additionally sheathed with plasterboard or wood, then the use of mineral wool is permitted.

This insulation product is best suited for structures made of wood or frame. Let's look at the main pros and cons of mineral wool.

The main advantages of this heat insulator:

  • Mineral wool has high level resistance to sudden temperature changes. In addition to thermal insulation characteristics, this material has excellent sound insulation properties.
  • The next plus is elasticity. Thanks to the previous factor (resistance to sudden temperature changes), mineral wool does not change in shape and does not change its structure.
  • Another advantage is durability.
  • This product is not flammable. You don't have to worry about safety. Mineral wool is not flammable.
  • For installation you do not need to have any specific knowledge or skills.

There are also disadvantages:

  • Mineral wool is brittle - this is one of the parameters that complicates the installation process.
  • Hygroscopicity. This product perfectly absorbs moisture. Because of this, the technical characteristics of mineral wool will deteriorate.
  • Price. Mineral wool costs quite a lot of money compared to other thermal insulation materials.

Mounting instructions:

  • First, it is necessary to seal all cracks and surface defects. Apply polyurethane foam.
  • Use nails or screws as fastening materials. Some people attach it with glue.
  • The slabs are laid from bottom to top.

Application of ecowool

This material is the most environmentally friendly. Ecowool contains recycled cellulose. This product is applied by spraying.

Let's consider the advantages:

  • Excellent breathability.
  • Although ecowool, like mineral wool, perfectly absorbs moisture, it dries in a short period of time. At the same time, its thermal insulation properties do not change.
  • Ecowool also contains specially designed additives that make the material resistant to fire.

The downside is that ecowool itself is quite expensive, but you still need to spend extra money on the equipment that is necessary to apply it to the surface. To carry out installation you must have certain knowledge and experience.

Ecowool is an excellent insulation material for walls inside walls in a country house.

Ecowool is installed using three methods:

  • dry method;
  • wet method;
  • wet-adhesive.

The wet method is the most commonly used. This includes the use of an adhesive - lignin. Ecowool, which is already moistened, can stick to the surface of the walls without problems. This method is used for thermal insulation of walls made of brick. First you need to make a sheathing from wooden blocks. After which the insulating material is applied using specially designed equipment.

Use of expanded polystyrene

This product is very popular among dacha owners. Expanded polystyrene has an average cost of construction market.

Expanded polystyrene has all the necessary advantages:

  • excellent strength;
  • moisture resistance;
  • ease of installation.

This is all that is needed to insulate the walls from the inside of the house.

Disadvantages of polystyrene foam:

  • low level of breathability;
  • poor adhesion to the facing surface;
  • not really .

Expanded polystyrene is great for country cottages.

First, before starting the installation procedure, it is necessary to prepare the surface. That is, you need to apply plaster. Then the walls need to be washed to remove dirt. Next, a primer is applied, which has deep penetration.

Installation begins with the application of glue. You will have ten minutes to lay the polystyrene foam board. Reduce the distance between slabs. If any gaps remain, they must be filled with parts of polystyrene foam. After installation of the slabs, the reinforcing mesh is laid. Fastening is done using plaster. The layer is five millimeters. After drying, you need to apply the final coat.

Application of foam plastic

Polystyrene foam is the cheapest insulation product on the construction market. Polystyrene foam has a high level of moisture resistance and a low level of thermal conductivity.

Main advantages:

  • Polystyrene foam is not afraid of fungus, mold and rot.
  • Due to its low weight, polystyrene foam can be installed without problems.
  • Strength. The product can withstand compression and bending.

Minuses:

  • The product may become deformed from impacts.
  • Poor airtightness.
  • Material may release toxins when ignited.

It is best to insulate walls that are built of brick with polystyrene foam. For wooden houses foam is not used.

Installation is carried out like expanded polystyrene.

Let's look at three tips:

  • When insulating the walls of a country house from the inside, you need to know that the inner layer of heat insulation will take up useful space. Therefore, it is best to insulate small country houses from the outside.
  • During installation, it is also necessary to take care of creating a ventilation gap, which should be located between the heat insulator and the decorative finish. What is the purpose of the ventilation gap? It is necessary so that the thermal insulation cake of the walls can be ventilated and the condensation can evaporate better.
  • When carrying out a vapor barrier, be sure to use a specially designed film, which will protect the heat insulator from getting wet and freezing. It will protect the heat insulator from losing its original technical characteristics.

This anti-condensation film can be used for vapor barrier and waterproofing not only walls, but roofs.

Wall insulation process

Thermal insulation of walls is the most important work because they occupy the largest area, and the highest heat transfer comes from them.

Before installing the heat insulator, it is necessary to prepare the surface:

  • It must be cleaned of dirt and dust.
  • Then treat the walls from the inside; this can be done using specially designed mixtures and aerosols. Thanks to this treatment you can protect wooden surface from pests. An excellent aerosol is Raptor for bedbugs ( professional product). This product is intended for removing bedbugs. The substance has a quick effect. The aerosol begins to act after a quarter of an hour. After using the aerosol, the room must be ventilated. You can also use dichlorvos instead of “bedbug raptor”.
  • Next you need to caulk all the cracks using dry tow.

Jute fabric is excellent as a heat insulator for the walls of a country house.

Its installation is easy; this is done using a construction stapler. It must be placed on a beam and secured using this construction tool. After the walls are erected, the canvas will be compacted.

Jute fabric does not rot. Moths “do not attack” this insulation material. Jute fabric has a low level of thermal conductivity due to the fact that it has a structure in the form of capillaries. This material is absolutely environmentally friendly. Mold or mildew will not form on it.

For the process of insulating the walls of a country house, it is better not to use products such as wool, batting, and so on.

Because these improvised products perfectly absorb moisture, which has a detrimental effect on heat retention. After a certain period of time, the material will become rotten. Wool also attracts moths.

Bottom line

Let's summarize. When choosing a particular insulation material, it is necessary to take into account its technical characteristics, such as the level of thermal conductivity, ease of installation, and level of resistance to sudden temperature changes.

You need to pay attention not only to the technical characteristics of the thermal insulation product; the material from which the house is built plays a vital role.

For many, cost is not the last parameter to which you should pay attention. If you choose a high-quality heat insulator, and the installation is carried out in compliance with all the rules, you will be able to achieve unique comfort and coziness in your country house. Often country houses not heated by

central heating

  • Thermal conductivity. This property is the most important when choosing insulation. The lower the thermal conductivity index, the better the optimal temperature is maintained - the air is cool in summer and warm in winter.
  • Immunity to low temperatures. Often people live in their dacha only in the summer, so no one heats it in winter. It is necessary to choose insulation that is not destroyed by frost.
  • Low cost. Since a dacha is needed only in summer time years, no one builds it from too expensive materials.
  • Simplicity of installation work. This criterion is important if the owner wants to install the thermal insulation layer himself.

Types of insulation

The following materials were recognized as the most suitable insulation materials for arranging a summer cottage, meeting all of the above requirements:

  • Mineral wool;
  • Expanded polystyrene;
  • Polyurethane foam.

Mineral wool is considered one of the best insulation materials because it has the following advantages:

  • Fire resistance;
  • High level of noise absorption;
  • Immunity to aggressive chemicals;
  • Almost complete absence of shrinkage.

Despite all its advantages, disadvantages also exist:

  • High vapor permeability;
  • High price;
  • Insulation requires a thick layer of material, which can lead to loss of usable space in the rooms.

If the owner is not too limited in funds, and specialists competently insulate a country house with mineral wool using additional vapor barrier, then such insulation is an excellent option.

Expanded polystyrene, more familiar as polystyrene foam, is ideal for insulating walls from the inside, and in this regard is no worse than mineral wool. The following advantages of expanded polystyrene can be noted:

  • Low thermal conductivity;
  • Good waterproofing properties;
  • Immunity to microorganisms and decay;
  • Very low cost;
  • Convenient installation.

No significant disadvantages of polystyrene foam were noted, except perhaps susceptibility to fire, but the insulation does not burn, but only smolders and goes out on its own, however, releasing many substances harmful to humans. Using expanded polystyrene, it is best to insulate a country house from the inside.

Extruded polystyrene is a type of ordinary polystyrene foam, but its advantages, compared to classic polystyrene foam, include:

  • Thinness of the slabs (no more than five centimeters);
  • Reduced flammability.

The disadvantages include its cost, which is higher than that of conventional polystyrene foam.

Polyurethane foam has rightfully earned one of the first places among insulation materials; its undoubted advantages cannot be denied:

  • Light weight that does not overload the walls;
  • Lowest thermal conductivity;
  • Possibility of processing relief surfaces without the formation of cracks and voids;
  • Good sound insulation;
  • Waterproofing properties;
  • Immunity to chemical and bacteriological influences.

But still, despite all the advantages, several disadvantages can be identified:

  • The need to use special equipment;
  • Lack of ability to do the work yourself;
  • High price.

It can be concluded that best insulation for walls inside a dacha house - this is polystyrene foam, especially if the dacha owner wants to save money. If it is possible to involve professionals and pay a large amount of money, then it is better to use mineral wool or polyurethane foam.

Wall insulation

If the dacha is intended not only for summer, but also for winter accommodation, you can’t do without careful insulation of the walls. First of all, you need to determine whether the walls will be insulated from the outside or from the inside (the first option is used most often; moreover, it gives you the opportunity to work with the facade and decorate your home).

Anyone who understands the nuances of construction can do the insulation of walls from the inside with their own hands. The work is performed in the following sequence:

  • The wall is prepared properly and primed;
  • The insulation is covered with a layer of glue and attached to the wall;
  • The tiles are arranged in a checkerboard pattern;
  • The joints between the tiles must be carefully sealed;
  • Putty is applied on top of the insulation, then a layer of decor is applied.

Insulation for walls inside a country house must be chosen so that it does not take up too much space. Mineral wool in this regard is not the best option.

Insulation on the facade side is carried out according to the following steps:

  • Along the perimeter of the house it is necessary to attach vertically wooden blocks for the frame, the distance between them should be sixty centimeters;
  • Insulation is placed between the bars;
  • Using slats, a film is secured over the insulation to protect against wind;
  • The wall is covered with an outer layer - siding or other decorative material.

Features of insulating a dacha from the inside

  • Insulating the dacha from the inside promotes the formation of condensation between the insulation layer and external wall building. The accumulating liquid wets the insulation and can lead to the appearance of mold on it and deterioration of the thermal insulation properties, and in the cold the water will harden and have an adverse effect on the walls. To prevent this condition, it is important to use either a vapor barrier material or install an additional layer of vapor barrier.
  • Since insulating a room from the inside will significantly reduce it, it is worth contacting specialists who, for an additional fee, will choose an insulation option and a frame for it that will not steal useful space.

  • Poorly sealed joints between insulation boards will lead to heat loss through the cracks; this must be taken into account.
  • Most materials used for thermal insulation are capable of releasing harmful substances; it is necessary to choose one that is not dangerous to human health.
  • Insulation of internal walls will not allow the temperature to remain stable, since exposure to sunlight, opened door or a window will quickly heat or cool the room.
  • To successfully install insulation inside the house, you do not need to invite specialists; the main advantage of this process is its simplicity; any good owner can handle it, which cannot be said about external insulation.

  • If the insulation used is vapor permeable, then it is necessary to make additional vapor barrier using special films;
  • Insulation and decorative finishing should not fit tightly to each other, it is necessary to leave a gap for the evaporation of the condensing liquid;
  • If the dacha is small, then insulating the dacha house from the inside can take up space, so it is better to place the insulation outside the house.

The question of how to insulate a dacha is especially acute for owners of country houses, since without good thermal insulation it will not only be impossible to live in it, but it will also not survive the winter without heating, the walls may become damp, the decor will fade and further repairs will cost more. It is better to immediately carry out competent work on thermal insulation and enjoy the warmth in winter and coolness in summer.
