Why can't you insulate a house from the inside? Instructions for insulating walls from the inside. Is it necessary to insulate walls?

Each owner has his own individual requirements for what his house or apartment should be like. The exception to the rule is heat. Especially in the cold season, when the air temperature outside goes below zero.

With the fact that housing should not only be beautiful, but also able to maintain a comfortable temperature even with a big minus, everyone without exception agrees.

The reason for this unanimity lies not only in the desire to avoid the need to stay at home in warm clothes, hindering movement.

The main troubles that follow freezing of walls are condensation, mold and fungi, which affect the health of residents.

In addition, the walls themselves suffer. If mold and mildew can be eliminated, then restored quality of the damaged wall It doesn't always work out.

Way out - internal insulation walls, protects against cold during frosts, and from condensation during thaw periods.

Advantages and disadvantages of thermal insulation

As a rule, the culprits reducing the comfortable temperature level indoors are heating systems, poorly insulated windows, or the roof of the house. If the heating, windows and roofing are normal, then the problem is really in the freezing walls, which require additional thermal insulation.

The indisputable advantages of internal wall protection against freezing include:

• the ability to insulate any room;
• performing work at any time of the year;
• the ability to carry out all the work yourself (significant savings);
• increasing the sound insulation of the home.

The disadvantages include:

• mandatory requirements for providing vapor barrier;
• the need to use insulation with excess thickness;
• consequences in the form of internal drafts;
• the need to create additional ventilation due to increased humidity;

Is it possible to insulate the walls inside an apartment?

Despite the fact that the option of internal insulation seems, at first glance, to be the most effective and profitable, experts recommend resorting to it only in the most extreme cases, if there is no other way out.

If the operating organization has been promising to carry out external insulation for years, but the residents do not have their own funds, then everything that is not recommended can be carried out, since is not strictly prohibited.

A significant disadvantage of mineral wool is ability to absorb moisture. The resulting dampness is an excellent breeding ground for pathogenic bacteria. In addition, excess water reduces thermal engineering priorities.

For panel house, for example, choosing mineral wool will not be the most successful. However, if it is necessary to insulate the walls wooden structure, you won’t find better mineral wool.

This natural organic material is capable of spontaneously release the generated steam beyond the outline of the structure, protecting the wood used for the construction.

Expanded polystyrene

Some of the most important characteristics insulation materials – moisture resistance and small specific gravity .

If mineral wool cannot boast of the ability to withstand moisture, then expanded polystyrene, both foamed and extruded (EPS), is quite satisfies the requirement.

The advantages of the material also include the low specific weight of the sheets and the absence of the need to install a metal frame.

All it takes is insulation of sheet joints expanded polystyrene and walls through the use of polyurethane wool.

Attach the polystyrene sheets themselves to the wall using glue or dowels.

Styrofoam

Obtained by foaming a suspension polymer.

Differs in specific structural structure, which determines high strength and service life, exceeding the similar characteristics of popular mineral wool.

Polystyrene foam, despite its high popularity, has both significant advantages and disadvantages.

Pros:

• high resistance to moisture;
• excellent thermal insulation properties;
• resistant to mold and fungal attack;
• easy to process and install;
• easy;
• no additional waterproofing required;
• has high resistance to temperature changes, heat, frost;
• provides good sound insulation;
• cheap.

Minuses:

• needs protection from mechanical damage due to limited mechanical strength;
• does not allow air to pass through;
• fire hazard;
• interaction with nitro paints and nitro varnishes should not be allowed;

Polyurethane foam

This material is considered a leader among modern insulation materials thanks to its reliability. Among the disadvantages of polyurethane foam are: the need to install frames.

Taking Additional Security Measures in connection with the application of a liquid two-component substance by spraying, as well as plastering with additional use nylon mesh.

Among the advantages of polyurethane foam: high moisture resistance, minimal hardening time, no need to use fasteners.

Glass wool

The characteristics are similar to mineral wool. The advantages include lower cost than mineral wool. The main disadvantage is shrinkage over time. In addition, glass wool is characterized by high fiber fragility. This complicates installation and requires careful adherence to safety regulations.

Environmentally friendly materials

We are talking about such unusual materials, like straw, reeds, gypsum panels. Despite difficulties with acquisition and searching for a contractor, this option of insulation is becoming increasingly popular.

But if there is no particular desire to search for material and artist, then you can use at least environmentally friendly materials– cork insulation or fiberboard, which is made from wood shavings.

In this article you can learn how to soundproof walls in an apartment.

Criterias of choice

In order to select the most successful option of insulation intended for internal insulation of walls, it is necessary first of all pay attention to the following characteristics:

1. Resistance to high temperatures and open fire (fire safety).
2. Low thermal conductivity, preventing the outflow of heat from the room.
3. Safety (absence of toxic substances and toxic impurities).
4. Durability and the ability to retain its original shape for a long time.
5. Resistant to moisture and aggressive substances.

The material from which the walls are made and its characteristics also play an important role.

If the walls are planned to be plastered, then it is best to insulate them with extruded polystyrene foam. Peculiarity - EPPS flammability group should not exceed G1.

The choice in favor of expanded polystyrene is also justified minimal capture of usable space.

If the walls are sheathed with plasterboard, then they can be insulated with mineral wool and other soft insulation materials, with the obligatory installation of a vapor barrier layer.

Insulate walls with polystyrene foam panel houses not recommended due to its high flammability and ability to accumulate moisture.

The main task of internal insulation of a house made of foam blocks is to provide vapor barrier thermal insulation material on both sides. Also casing must be done(second wall). For this purpose, drywall or lining is used.

Accordingly, soft cotton insulation or polystyrene foam will not work. It is best to use polyurethane foam, penoplex and polystyrene foam.

Wooden house made of environmentally pure material , and the choice of insulation is guided precisely by this characteristic. The best option for insulation of wooden walls of a private house - laying ecowool. It is also possible to use polystyrene foam and penoplex, which cannot be said about polystyrene foam.

Expanded polystyrene during operation begins to release carcinogenic substances harmful to humans and animals.

Mineral wool is well suited for insulating an apartment. if the footage allows. You can also use polystyrene foam, provided you first apply a layer of liquid waterproofing to the prepared wall surface.

However, polystyrene foam, like penoplex or foil penofol, is a waterproof material, increasing the risk of mold and mildew formation.

Cork material, warm plaster or fiberboard are excellent for insulating apartment walls. This is only a small part of the insulation materials available on the market, so the choice must be made based on the characteristics of the apartment’s external wall, as well as room finishing options.

How to insulate walls with your own hands?

The algorithm for insulating walls in an apartment from the inside depends on the type of house and the selected insulation. However the main stages of work remain unchanged in any case:

Insulating walls from the inside with polystyrene foam: video instructions.

Plaster on insulation

Protective leveling layer on the surface of polystyrene insulation created using reinforcing mesh and a special mass designed for this type of material.

The mesh, which does not allow the decorative coating to deform in the future, is glued thin layer plaster. Then a thin leveling layer is applied universal mass. The treated surface is left to dry for at least a day.

After drying, the surface can be rubbed. After mashing, the treated surface is primed. Final stage works - decorative design.

External wall insulation is an expensive method of insulation, and some apartment owners try to insulate at least 1-2 walls. Having studied this question, I wondered whether external thermal insulation of the walls of a “separate apartment”, and not the entire house, is really effective. At the same time, the ones swarming on the walls are becoming more and more noticeable. multi-storey buildings specialists in external insulation of walls of individual apartments. It feels like the city is turning into an old patchwork quilt.

Many people write that after covering with polystyrene foam the apartment became 2-3 degrees warmer. Some did not feel any change at all. No company guarantees that it will become 10 degrees warmer; Often degrees, as such, are not discussed at all in the advertising brochures of construction companies. I had a long and passionate discussion on this issue with an old builder friend and we came to a common opinion on some things. the main problem: regardless of whether the technical conditions for insulation are met or not - external load-bearing walls are subjected to sudden temperature changes and are gradually destroyed. And no one will tell you about this... Besides this, there are several more unpleasant moments.

External wall insulation is not effective if:

• Ground floor apartment with icy floors and a damp, open basement.
• The walls of the apartment face the entrance, where the windows are broken and the radiators do not work.
• The apartment has old windows with rattling glass.
• The doors are not insulated or there are gaps at the front door.
• The apartment is on the top floor and the roof is not insulated, the exit to the roof and the vent windows are not closed, where a lot of snow blows in in winter (this is familiar to me, since I live on the 9th floor and there are problems top floors take place..)
• The seams are leaking upper floors, and along “kilometer-long” hidden grooves the moisture flows to you. Covering a separate apartment will only make the problem worse.

Even after doing such an expensive job of insulation and not eliminating the above-mentioned problems, all the work is down the drain. Plus, WITH DISTRICT HEATING, YOU WILL NOT PAY LESS FOR IT. If you believe the specialist builders, their calculations are as follows: even with the modernization of the entire house and the installation autonomous heating, it pays off in no less than 15 years. But in a separate apartment with centralized heating, this will never pay off. Except that your electricity bill will be 10 hryvnia less per month if you run an electric heater (this is purely relative).

Currently there are various modern technologies, allowing you to see where the main heat leaks occur in your house or apartment - for example. Be sure to ask the craftsmen who will offer you services for insulating facades, a photo of at least one object they have insulated, photographs of this object in the infrared range, indicating the address of the object. Ideal would be BEFORE and AFTER. So they smiled at me and no longer offered to warm me up...

An alternative to external wall insulation

Having moved into a one-room apartment on the 9th floor of a 9-story block building, and having lived in it for 2 years, I realized that I couldn’t continue living like this. The walls in the kitchen were covered with moisture and frost in winter, and the whistle from the windows was no worse than the Nightingale the Robber. In the living room, the corner of the wall, one side facing the balcony and the other facing the neighbor’s loggia, was damp and black mold appeared.

Repeatedly, climbers filled the cracks with resin and covered the joints of the slabs - to no avail. He gave up on everything and took matters into his own hands - he insulated the external walls from the inside. The first thing I did was replace the windows with metal-plastic ones, but this did not solve the problem. The walls didn't just "cry", they "sobbed".

I waited until summer - the walls dried out naturally and, just to be sure, I went over it with a hairdryer. I decided to use regular foam roll insulation under the cardboard-based wallpaper. The fungus was removed by hand. Having filled as much as possible the cracks on the walls, I opened them several times with a primer to destroy fungus and mold “Ceresite”. After drying I pasted it on roll insulation under wallpaper on putty walls using regular finishing putty, which remained after puttingtying the walls. I hung wallpaper. And...Oh, miracle! I didn't even have to change the heating radiators at that time; It’s been more than 10 years since I forgot about fungus, cold and dampness. The radiators were changed only last year. I wrote how I chose the radiator.

I am sure that you should first try to solve the issue of thermal insulation with your own hands before carrying out thorough reconstructions of your apartment. External wall insulation is more of a fashion statement than a panacea for the ills of cold, damp apartments. When I was preparing the article, I got to foreign sites and blogs - well, no one insulates facades, even in the northern states, everything is done from the inside (they even insulate with straw :)). This is worth thinking about... In the next article I will cover the topic

Surely the residents apartment buildings They envy a little those who live outside the city in a private building. Own living space, garden, fresh air- everyone's dream. Alas, not everything is so simple, because the harsh Russian winters force you to carefully insulate your home to avoid freezing. This requires significant investments and constant monitoring of the condition of the thermal insulation material, from which residents of urban houses are exempt.

Insulating a home is preferable to using ten heating devices- you can save money and also make your home more comfortable. It is known that there are two ways to insulate a private building - from the outside and from the inside. Experienced experts recommend using both, but it’s worth taking care of external insulation first. Read more about which material is best suited for which houses.

Requirements for thermal insulation material

The consumer does not face a long search for good products - the market is saturated with goods different manufacturers, so in any hardware store you can choose a decent insulation. However, before purchasing, it is necessary to analyze the material in question according to its physical and chemical properties. These include:

• thermal conductivity coefficient (characterizes the ability of the insulation to conduct or retain air; the lower the indicator, the better - you won’t have to use thick layer material);
• moisture absorption coefficient (indicates the ability of the material to absorb water as a percentage by weight; the higher the indicator, the less durable the insulation);
• density (based on the value, you can determine how heavy the material will make the house);
• fire resistance (there are 4 flammability classes; the first (G1) is the most preferable, which stops burning without an open source of fire);
• environmental friendliness (not the most important indicator for consumers, and in vain - to preserve the health of family members, it is worth choosing only natural material made from natural components, does not emit impurities into the atmosphere and does not contain synthetic elements);
• durability (the service life of the insulation set by the manufacturer);
• hygroscopicity (the ability to absorb vapor from the air);
• resistance to pests (insects, rodents, birds);
• noise insulation properties;
• ease of installation (the insulation should be fixed quickly, when minimum set tools; also a minimum quantity must be produced with it additional work like cutting into even pieces).

It is difficult to choose a material that has all the desired qualities. For this reason, it is possible and necessary to perform insulation both outside and inside.

Advantages of external thermal insulation

The question of insulating a private house from the outside arises in two cases - at the design stage of a building or when purchasing a ready-made one, but which does not have decent thermal insulation. The second situation occurs more often. What are the advantages of insulating your home from the outside? These include:

• reduced deformability of walls due to additional protection;
• the facade perceives sharp temperature fluctuations; as a result, the service life of the structure will be extended;
• freedom in choosing the design of the facade, even when the building is erected;
• the area of ​​the interior remains unchanged; this allows you to carry out any finishing you like, and the living conditions will remain the same.

Methods for external insulation of a house

The need and benefits of external thermal insulation are obvious; Now the consumer should familiarize himself with insulation methods. There are three of them:

• “well” arrangement of the material;
• “wet” insulation with gluing;
• ventilated facade.

In the first case, the insulation is placed inside the walls (for example, between layers of brick). It turns out that he is “locked” between two levels. The method is effective, but it is impossible to implement it for an already built house.

In the second case, the insulation layer is fixed with glue on the outside of the walls, then additionally attached to dowels. Several types of coatings are applied on top - reinforcing, intermediate, decorative (finishing). Good way, only requires the intervention of specialists; It is impossible to carry out wet insulation of walls with your own hands without experience.

The ventilated facade resembles “well” masonry, only the outer layer acts facing material- drywall, tiles, siding, etc. Additionally, you will have to build frame system for fastening heat insulation sheets.

The last method is the most popular, widespread and profitable. It will cost much less than “wet” insulation; Moreover, even a beginner can do the job with his own hands. Now the consumer faces the most difficult choice.

Existing materials can be divided into two large groups - organic (natural origin) and inorganic (obtained using special materials and equipment).

Types and advantages of inorganic insulation

The first place on the list rightfully belongs to the most popular material - mineral wool. It comes in three types - stone (basalt), glass and slag. Differing from each other only in appearance, varieties of mineral wool have the following qualities:

• low thermal conductivity coefficient (0.03 - 0.045);
• density variations (from 20 to 200 kg/m3);
• excellent sound insulation properties;
• vapor permeability (mineral wool can “breathe”);
• fire resistance.

It is not without a number of disadvantages, including:

• attractive to rodents and insectoids;
• deterioration thermal insulation characteristics by 50% when only 3-5% of the volume is wet;
• never completely dries out.

In general, mineral wool is good, but it is highly undesirable to use it for cladding the outside of a house.

The second well-known external insulation is polystyrene foam. Its advantages:

• the heat conductivity coefficient is slightly lower than that of mineral wool (0.03 - 0.037);
• costs less than other insulation materials;
• light;
• density from 11 to 40 kg/m3.

• fragility;
• release of toxic substances during fire;
• does not “breathe”, which forces residents to build additional supply and exhaust ventilation;
• When directly wet, it absorbs moisture, becoming unsuitable for use.

Extruded polystyrene foam is not inferior in thermal conductivity to mineral wool and polystyrene foam. In addition, he:

• does not absorb moisture;
• convenient for installation, because it is produced in slabs;
• stronger than foam;
• almost does not allow air to pass through.

Flaws:

• highly flammable;
• When burned, it releases harmful substances.

There is another type of raw material used for external thermal insulation the walls of the house are “warm” plasters. They are a mixture of balls (formed by glass, cement and hydrophobic additives). They “breathe”, insulate the room from moisture, do not burn, are not afraid of sunlight, and are easy to repair. Not very common on the market, however, experienced consumers have already appreciated this insulation.

Types and advantages of organic materials

Those who want to feel maximum closeness to nature are recommended to use raw materials from natural ingredients. These include:

• cork insulation - have a thermal insulation coefficient of 0.045 - 0.06; are crushed tree bark, compressed under the influence of hot steam and resin as a binding element; easy to cut, “breathe”, does not form mold, non-toxic; today they are increasingly used for insulating walls outside);
• cellulose wool (ecowool) - thermal conductivity from 0.032 to 0.038; They are crushed cellulose treated with fire retardants to increase fire-fighting properties; properties resemble cork materials, but absorb liquid better; do not withstand heavy loads and are not suitable for wall cladding;
• hemp - supplied in slabs, rolls, mats based on hemp fibers; does not hold the load well, although it is quite dense (20-60 kg/m3);
• straw is an ancient way of insulating the walls of a house; breathable material treated with fire retardants to reduce flammability; today it is practically not used;
• seaweed is an exotic method of covering external walls; density up to 80 kg/m3, do not burn, do not rot, are not of interest to rodents, resistant to mold and mildew. Better suited for light walls.

Preferred insulation materials for house cladding

Each material has pros and cons. Based on the information presented above, we can make a symbolic rating of the most quality materials for the walls of the house (the first one is the most preferable, etc.). It is also worth considering the type of facade design.

For ventilated systems would be better suited cotton wool - mineral, cellulose. When laying wells, preference should be given to materials that do not allow moisture to pass through. This is extruded polystyrene foam. Plaster finishing of walls goes well with insulation, whose density is more than 30 kg/m3. For example, with mineral wool, polystyrene foam, polystyrene foam, and any organic material.

For light walls wooden house A breathable material is better - mineral wool, hemp, ecowool, cork insulation. The first is preferable, but costs a little more.

A country house must be high-quality sheathed with reliable material. The consumer can choose any of those discussed earlier, guided by his wishes or financial capabilities. A competent approach to purchasing insulation is the key to the long service life of a cozy home.

The mistake of many novice, inexperienced builders or too economical owners of premises is the desire to ensure the preservation high temperature V winter period by insulating the house from the inside.

Before starting work, craftsmen are obliged to warn the owners why it is impossible to insulate the house from the inside, and what consequences await them in the end: unpredictable climate change in a confined space, high humidity and violation of the integrity of the walls, fungus, mold and even small puddles from large quantity condensate

Why can you insulate a house from the outside but not from the inside?

Preserving living space and reducing the difference between external and internal temperature fluctuations, preventing dry air and the formation of increased moisture makes external insulation more expedient. Why and how is it better to insulate a house from the outside:

• Styrofoam. Retains heat, prevents moisture, but is vulnerable to direct sun rays. Highly flammable;
• fibrous mineral wool. Good vapor permeability, sound insulation and fire resistance;
• penoplex. It has minimal thermal conductivity, is not susceptible to moisture and is resistant to combustion;
• liquid polyurethane foam insulation. Prevents the formation of condensation and humidity, does not form cracks, the material is resistant to mold and fungal infections;
• basalt slabs. They contain a sufficient amount of formaldehyde, which repels small rodents, quickly covers the required area, is not susceptible to sudden temperature changes, and eliminates rotting and inflammation. Provides warmth and sound insulation.

Processed a little differently outer surface log cabins. Ecologically pure natural material quickly absorbs moisture, which means it requires more careful and reliable protection. To insulate a house made of timber from the outside, glass wool, modern polymers and felt are sufficient.

But even qualified specialists in some cases refuse to work because of customers who have absolutely no idea why you can’t insulate a house from the inside:

• the area of ​​the room is reduced;
• danger of high humidity interior space and insulation. The heating temperature of the walls may differ from room temperature, condensation begins to form, fungus and mold appear;
• ventilation disturbance;
• reduction in the strength and thermal insulation characteristics of walls.

Improperly carried out insulation will entail changes in the facade of the building, large expenses, and an insufficiently ventilated room will also provoke diseases of the respiratory system.

Is it possible and why not to insulate a house from the inside?

Carry out any tasks independently construction works, which relate to changes in premises, should not be done. Only an experienced specialist will determine how to insulate a house from the inside:

• warm seam Perfect option for a wooden house. The sealant is placed only between the logs on the ceiling and facade. Linen tape and felt are also used. As a last resort, the seams can simply be caulked;
• mineral wool. An environmentally friendly and inexpensive product, it provides noise insulation and retains heat in houses made of log house, not affected by fungus. Disadvantages include the need for additional installation on top of mineral wool with a special vapor barrier. It dries quickly when wet internal material, but does not eliminate the accompanying problem, such as shrinkage at high humidity;
• expanded polystyrene. A lightweight and moisture-resistant polymer analogue of synthetic foam. Susceptible to fungal diseases, therefore, before using it, the walls are pre-treated protective equipment. Walls and ceilings are cleaned and leveled, joints are foamed. TO wooden surfaces and does not apply to log houses;
• liquid polyurethane foam. Requires a pre-fabricated frame, which will fill the material. After insulation, you will need to plaster the ceiling and walls using a special mesh.

All materials that are usually used to insulate a room before the onset of cold weather have a lot of disadvantages and side effects. It is a pity that many people do not want to accept why it is impossible to insulate a house from the inside.

Insulating a house from the outside is, on the one hand, a fairly simple procedure that you can handle on your own, even without any experience. But, on the other hand, this operation raises a lot of questions, and also requires strict adherence technology, otherwise the result will not meet your expectations. Therefore, below I will describe to you several ways to perform external insulation as efficiently as possible and without damaging the structure.

Methods of external insulation

Many people who are faced with insulation for the first time do not know how best to place thermal insulation from the inside or outside. According to SNiP 3.03.01-87, in private houses, for a number of reasons, external thermal insulation should be performed:

• if you place the heat insulator from the inside, the walls will freeze even more than before insulation. Moreover, a heat insulator will form in the space between the wall and the insulation;
• It is impossible to provide thermal insulation of the ceiling from the inside, resulting in insulation that is inadequate;
• Internal insulation reduces living space.

Thus, the answer to the question posed above is unequivocal - internal insulation is carried out only in cases of extreme necessity.

So, if you decide to insulate the outside of the house with your own hands, you will need dry thermal insulation material in the form of slabs or mats. As a rule, mineral wool or polystyrene foam is used as insulation. With their help, you can insulate the facade in several ways:

• wet facade – the technology consists of gluing insulation and applying plaster on top of it. This method is widely used due to its relative cheapness. Its disadvantage is the low strength of the facade and fragility, compared to other finishing methods;

• curtain façade– is a frame to which facade materials are attached (siding, lining, facade, etc.). The insulation is located in the space between finishing material and a wall. This finish is more durable, but at the same time costs more;
• cladding with thermal insulation blocks, which can be made of wood concrete, foam concrete, gas silicate, etc. I must say that thermal insulation properties These materials are worse than polystyrene foam or, for example, mineral wool. But they have higher strength.

If, for example, you need to insulate an old wooden or country house frame house, then this method of insulation is the best solution. Moreover, block insulation can be combined with other heat insulators.

Everyone must decide how and with what to insulate the house from the outside, depending on the situation, financial capabilities and wishes regarding the design of the facade. As you can see, each of these methods has its own advantages and disadvantages.

Below we will consider in more detail all the insulation options described above.

Wet facade

First of all, I will tell you how to properly create a wet facade. To do this you will need the following materials:

• insulation in the form of mats or slabs (mineral wool, expanded polystyrene or extruded polystyrene foam);
• special dowels for insulation (“fungi”);
• glue for insulation;
• aluminum perforated corners
• fiberglass mesh;
• primer;
• decorative plaster;
• dye.

Before buying a heat insulator, people are always interested in what is the best way to insulate a house from the outside? If the house is brick or made of other non-combustible materials, you can save money and use polystyrene foam. If the structure is wooden, it is necessary to use mineral wool, which will serve as fire protection.

The process of installing insulation with your own hands looks like this:

1. first of all, you need to prepare the facade for work - dismantle all elements that will interfere with the installation of insulation;
2. then you need to dilute the glue with water according to the instructions on the package;
3. Next, the glue is applied to the surface of the insulation using a notched trowel. If the walls are uneven, you can apply glue in “blobs” in the corners and in the center, which will give more opportunity to align the slabs relative to each other.

It should be noted that at this stage it is necessary to ensure an even vertical surface walls, therefore, in the process of gluing the insulation, you need to use a level and beacons (a horizontally stretched thread along the wall along which each row of heat insulation is aligned);

1. then the insulation is additionally fixed with dowels. To do this, holes are drilled in the wall directly through the slabs or mats. The dowels must be driven in so that they are recessed and do not protrude above the surface of the wall;

1. The slopes are glued over in the same way, the only thing is that they are not fixed with dowels;
2. after this, the evenness of the walls should be checked as a rule; if necessary, individual areas can be floated;
3. after that for everything external corners perforated aluminum corners are glued;
4. then the screw caps are covered with glue;
5. The next step is gluing the mesh. To do this, you need to use the same glue that is applied with a spatula to the surface of the insulation. A mesh is immediately applied to the treated surface and a spatula is passed over it, as a result of which it is embedded in the adhesive composition.

I note that the mesh must first be cut into sheets of the required length, taking into account the fact that it should be overlapped and turned over at the corners;

1. After drying, the glue is reapplied to the surface of the walls in a thin layer. In order for the composition to lay down evenly, the solution must be made more liquid than for gluing;
2. when the glue has dried, the surface is treated with a primer using a paint roller. The composition is applied in two passes;

1. After the soil has dried, decorative plaster is applied to the surface and leveled with a fine trowel. When the composition begins to set, the plaster is rubbed with sandpaper in a circular or reciprocating motion;
2. the final stage is painting. There is nothing complicated in this procedure - the roller must be dipped into a bath of paint and then treated with it on the wall. The paint is applied in two layers.

This completes the work. It should be noted that using this technology it is possible to insulate not only a private house, but also an apartment.

Curtain facade

Making a curtain façade on your own is no more difficult than a wet one. To do this, you need to prepare the following materials:

• insulation in the form of mats or slabs;
• metal profile or wooden beam for mounting the frame;
• adjustable brackets;
• vapor barrier film;
• dowels for insulation;
• finishing material for the facade.

Many people are sure that the cheaper the heat insulator, the better. However, the same mineral wool or polystyrene foam can be different quality. For example, cheap mineral wool can be exposed to moisture, and polystyrene foam can easily ignite and sustain combustion, so it is better to use materials from well-known brands, even if they are not the cheapest.

Insulation instructions look like this:

1. After preparing the facade, you must first carry out installation. There are quite a lot of options for its design and placement of insulation in it. Most often, racks are mounted on brackets, between which mats or slabs are placed.
   It must be said that installation of the frame is the most critical stage, since the evenness of the walls depends on it. Therefore, all racks must be placed in the same vertical plane;

1. then insulation is laid between the racks and fixed with dowels;
2. then a vapor barrier film is attached over the insulation. As a rule, it is fixed on a frame. To do this, you can use slats that are mounted horizontally, with the film located between them and the racks;
3. at the end of the work the frame is sheathed facade material, after which additional elements are installed - ebbs, corners, etc.

That's it for the montage curtain façade completed with your own hands.

Cladding with thermal insulation blocks

If you need to insulate an old, for example, log house, then it is better to build additional walls for it, which will also serve as insulation. Of course, this will require more time and effort, but the result is well worth the expense.

There are quite a lot of options for covering walls. The most common materials are:

• blocks from Sibit (it would be more correct to say aerated concrete, since Sibit is the name of the enterprise, which people began to call the material it produces);
• wood concrete blocks - made from wood chips mixed with cement;
• gas silicate blocks - resemble aerated concrete, however, their composition is based on lime. Besides, this material obtained by autoclave;
• made of polystyrene concrete – contain foam granules in their structure;
• from expanded clay concrete – contain expanded clay granules in their structure.

So that you can decide on the materials yourself and understand, for example, why a gas silicate block is better in comparison, for example, with aerated concrete, below I will provide a table with the main characteristics of these materials:

As we see, some materials benefit in strength, others – in thermal conductivity. Eg, gas silicate block more durable than wood concrete, but at the same time it is more heat-conducting.

Certainly, important factor The choice is also the price of the material. Arbolite blocks cost about 4,000 rubles per cubic meter, and polystyrene concrete material costs about the same. The price of gas silicate is slightly cheaper - about 3,000 rubles per cubic meter.

The house cladding technology is as follows:

• A shallow foundation is laid around the perimeter of the house. On our portal you can find detailed information about the arrangement of such a foundation;
