How to insulate a corner apartment from the inside. Wall insulation in a corner apartment from the inside

It is worth thinking about how to insulate a wall in a corner apartment from the inside even before the onset of winter frosts. Many, especially residents of the northern regions, are well aware that you should not rely on a home heating system. Therefore, it is best to prepare tools and materials in advance and insulate the corner apartment yourself. Moreover, it is not as difficult to do as it seems.

Why insulate corner-type apartments?

Despite the rapid growth in the number of modern residential complexes, many Russians still live in outdated Khrushchev apartments. These buildings are distinguished by old heating systems and do not withstand sudden weather changes. First of all, residents of corner apartments suffer from this. With the first cold snaps, it becomes cold in their dwellings, because cool air very quickly penetrates into the cracks in the walls of buildings. Another important reason for the need to install insulation lies in the layout of corner apartments. In them, not one, but two walls border the street, which further aggravates the situation of the residents. In such situations, even the presence of batteries and additional heaters does not save the inhabitants.

Due to severe frosts, the corners of adjacent walls of the room are frosted over. As a result, plaster and wallpaper depart from the surface, which causes the appearance of mold and fungus. In the corner rooms it becomes very damp, and an unpleasant smell forms, which interferes with normal living. Unable to withstand such conditions, sooner or later people ask themselves: "How to insulate a corner bedroom or living room?". With the help of this necessary procedure, you can not only make your stay more comfortable, but also save on heating. Plus, the residents of the house will be protected from dangerous fungi that cause asthma and other respiratory diseases.

Choosing a material - mineral wool or polystyrene?

Today, in order to, there are a lot of different materials. They are classified into those that are used for installation outside, and those that are intended for installation inside the house. It is worth remembering that some kind of universal material does not exist, because each of the heaters has its own advantages and disadvantages. Among the main requirements for materials, we can distinguish:

• high thermal conductivity;
• air tightness;
• ability to absorb moisture;
• appropriate environmental friendliness;
• resistance to ignition;
• long service life.

Using the crate

To have an idea about the properties of the most popular materials, it is worth considering each of them in more detail. Mineral wool has long been considered the most popular insulation. The main raw material for the production of this insulation is basalt. The material is among the products with a low degree of flammability. Even if the product starts to burn, it does not emit acrid smoke that can somehow harm a person.

Installing mineral wool does not require skills. This material is very malleable and plastic, it is tightly pressed against the wall and does not lag behind it for a long time. However, after a certain time, cotton wool absorbs moisture and begins to deform. In addition, as a result of the research, it was found that the material contains a small proportion of substances that adversely affect the human respiratory tract. Among other shortcomings, it is worth highlighting the large mass of the product, which makes its installation alone difficult.

Another popular material is polystyrene foam or, as it is also called, polystyrene foam. This is polystyrene well whipped with a powerful mixer, cooled to low temperatures. The prices for this product are very low, and installation does not require skills and high physical costs. The lion's share of the composition of the material is ordinary air, so it is absolutely harmless to the health of residents. This insulation is one of the few that can be used both for work outside and inside the building. The reason is resistance to temperature changes from -170 to +60 ° C.

Insulation can be mounted on various surfaces. It does not require the use of special fasteners. Another advantage of the material is its long service life. In addition to the advantages, the insulation has its drawbacks. So, the material cannot be used for installation in a wooden building, as it produces a large amount of condensate inside it. However, the product works perfectly in a brick building or in buildings built from concrete blocks.

Installation of insulation inside a panel building - where to start?

Features of the installation of the material may vary slightly, depending on the type of building. The first option that we will consider is a panel building. So that in the rooms of a corner apartment, first of all, it is necessary to clean the surfaces. Therefore, it is best to mount the material immediately before performing cosmetic or major repairs. As soon as the surfaces are cleaned, proceed with the installation of waterproofing in the form of special polymer membranes. In the vast majority of cases, their role is played by polyethylene films with a thickness of no more than 0.3 mm.

Insulation of the apartment from the inside

When stretching the waterproofing, it is very important to install the material as accurately as possible, without leaving any section of the wall open. To do this, select the membrane clearly in accordance with the area of ​​\u200b\u200bthe apartment. If there are no whole pieces of material on sale, it can be purchased in the form of wide strips. The next step will be the installation of a wooden or metal crate. An important nuance - if the structure is made of wood, it will need to be treated with an antiseptic before installation. The distance between the partitions of the crate should not be less than the width of one unit of insulation.

So, if you bought polyurethane foam slabs with a width of 2 m, then the distance between the partitions of the structure should also be 2 m. So you can install insulation without leaving gaps

Insulation installation

After installing the crate, it's time to install the material for insulation. Most products are made in the form of mats, one side of which is springy. When you squeeze the material, it shrinks, and then immediately returns to its original shape. This makes the installation of insulation much easier. After installation, the surfaces of the material are pulled over with a vapor barrier. It will provide insulation of walls and insulation from condensate. At this stage, you also need to try to act as accurately as possible, without leaving cracks or grooves. For greater reliability, sealant should be applied at the joints of the vapor barrier.

Installing material in a brick building - tips for amateurs

The process of installing insulation inside a brick building has its own characteristics and is slightly different from the insulation of rooms in a panel building. At the same time, there should not be any special difficulties in the process of work. Since expanded polystyrene is considered the most popular material for this type of work, we will consider the algorithm of work using the example of this particular insulation.

Insulation with expanded polystyrene

First of all, you need to properly prepare the surface of the brick wall. If there is no plaster on it, then it must be applied. If you are starting to install insulation in an already living room, then dismantle the wall decoration and putty before installation. If necessary, level the surface of the walls, seal all gaps and cracks and apply a primer that will penetrate into the smallest and deepest pores. It is important that the primer contains substances with antiseptic properties.

The next step is to dilute the glue. This is done strictly according to the instructions for use of the composition. We apply the mixture to the surface of the walls with a smooth spatula, after which we work through the layer with a tool with teeth. Without waiting for the glue to dry, we take sheets of expanded polystyrene and apply them to the wall in turn, pressing tightly and holding for several seconds. It makes no sense to use dowels to fix the insulation, since the glue will perfectly hold the material on the wall.

We mount plates without gaps

When installing each plate, make sure that there are no gaps between them! Remember that the denser the material is installed, the warmer it will be in your apartment. Further actions depend only on your plans. If you decide to put putty on top of the insulation, you will need to prime the surface before that. If plaster is to be applied, a reinforcing mesh must be installed.

Styrofoam grades - the most popular insulation

In stores you can find not one, but several brands of polystyrene foam at once. Depending on the method of production of the material, the inscriptions "PS" and "PSB" can be found on the packages. The first means that the material was made by pressing, and the second - non-pressing. In addition to this marking, there are also numbers on the foam packaging. What do they mean?

So, S-15- This is a very dense material produced by the non-pressing method. This foam is great for outdoor work in multi-storey buildings, it is often used to insulate attics and roofs. Among its properties, it is worth highlighting environmental friendliness, high moisture resistance and fire resistance. S-25 PSB- This is another insulation made by a non-pressing method. This foam is great for installation in corner apartments, as it has all the necessary qualities for this. In addition, this type of expanded polystyrene is often used to insulate floors and loggias.

Styrofoam grade S-35 PSB

If there are a large number of communications in the walls, or their installation is only planned, then for better insulation it is worth choosing a brand of foam S-35 PSB. The great advantage of the material is its resistance to bad weather conditions. It is absolutely not afraid of mechanical damage and has high fire resistance. The most dense is the expanded polystyrene brand S-50 PSB. It is often used in regions where hail often falls and strong winds blow. Such a heater is not afraid of precipitation, condensation or mechanical damage. True, its cost is quite high.

Mineral foam - how to decide?

This material is also in high demand due to its characteristics and reliability. However, not all of its brands are suitable for certain jobs. So, cotton wool with markings P-75 will be an excellent heater in corner apartments. She is not afraid of moisture and fire. However, if this material is not laid correctly, it deforms very quickly due to the ability to absorb condensate vapors. Mineral wool P-125 denser and stronger than the first type. It is often mounted outside brick and concrete buildings in regions with a mild climate. However, it is completely unsuitable for use in buildings located in the northernmost regions of Russia. Another disadvantage of this material is its high cost.

Cotton wool stamps PPZh-200 and PZh-175 characterized by increased density and rigidity. She is not afraid of fluctuations in temperature, the influence of frequent precipitation. The only drawback is the large mass of plates. To insulate housing, it is required to involve 3-4 people. As for the manufacturers of the material, the products of companies are considered to be of the highest quality. Isover, Ursa, rockwool and Isorok.

Freezing of the corners of the house is a nuisance that residents of both a panel Khrushchev or a brick new building and a country house, whether it be wooden or stone, may encounter. Fortunately, this serious problem can be solved on your own. Let's talk about how to properly get rid of the freezing of the corners of the house.

Why do corners freeze?

Due to cold bridges, corners are the most vulnerable part of almost any home. These sections of the building structure have increased thermal conductivity. Any vertical or horizontal angle is a geometric cold bridge. If a construction defect is allowed - poorly sealed seams, through voids in concrete, an insufficient layer of mortar between the bricks, the absence of the necessary insulation - problems cannot be avoided. Where there are cold bridges, the temperature of the wall surface in winter can drop below the dew point (up to about 9 ° C and 50% humidity) while maintaining room temperature indoors. It is in such places that, due to the temperature difference, condensation forms, which leads to the formation of mold, and when it freezes, it turns into ice crystals.

The most logical solution in this case seems to be laying insulation from the inside along the walls. But any such material is essentially a heat insulator, which equally insulates the wall from both heat and cold. The use of insulation can even worsen the situation, as it will shift the dew point (the place where cold and warm air touch) to the inner surface of the wall. As a result, cold air from the street will freeze the wall through and through, since the heat from the apartment will not be able to penetrate through the heat insulator layer. Wetting and freezing will continue, the insulation will become unusable and cease to perform its functions. In addition, the ice crystals will continue to break down the wall material, further increasing the thermal bridges.

When buying a country house or an expensive apartment, you can use the services of companies offering thermal imaging. Specialists will help to detect all heat leaks and conclude whether it is possible to correct builders' mistakes. This can save owners from many troubles associated with the operation of the house, and will save considerable money.

Getting rid of freezing corners

The ideal way to solve the problem is to insulate the entire facade from the outside and securely seal the seams. It is quite possible to repair your own country house, but in an apartment building you will have to turn to the management company for help. But do not despair. And in a single apartment you can get a good result.

First of all, you need to remove the wallpaper. If there are no visible cracks, then the walls are tapped with a hammer - where there are voids, the sound will be deaf. Next, remove the plaster over the discovered cavities and dry the corner thoroughly. If there is mold, be sure to treat with special antifungal agents. Sometimes the mold infestation is so extensive that the use of acid, blowtorch fire, or surface milling is necessary. All cracks and voids are filled with mounting foam or liquid foam. This will prevent moisture from entering the room even if there are cracks in the outer wall. And finally, the remaining foam is cleaned and the corner is plastered. Work is best done in the warm season to completely get rid of dampness and mold indoors.

In the event that very large voids are found, they should not be filled with mineral wool or tow, as these materials contribute to the accumulation of moisture. It's better to use the same . It is resistant to moisture, is not subject to rotting and mold, has high adhesive properties, does not lose its qualities when frozen.

Insulation of the entire facade from the outside

Today, manufacturers offer a variety of materials that greatly facilitate the repair process and bring it to a whole new level. For example, special heat-insulating ("warm") - light mixtures, in which microscopic polystyrene foam granules or light natural aggregates are used instead of sand. Such plaster is several times lighter than usual, it is well applied and sets. Due to the presence of air pores, warm mixtures have high vapor permeability, regulate condensation and ensure a healthy indoor climate. A layer of warm plaster of 50 mm in terms of heat-insulating effect is equivalent to laying one and a half to two bricks or a two-centimeter layer of polystyrene foam.

Not so long ago, new materials appeared on the market, produced by different manufacturers under different trademarks, but united by the common name "liquid thermal insulation". It is indispensable for such problem areas as freezing corners. The paint-like insulation suspension consists of hollow microspheres (ceramic, glass, silicone or polyurethane) that effectively reflect heat radiation. The microspheres are suspended in a binder composition of synthetic rubber or acrylic polymers, antifungal and anti-corrosion additives and coloring pigments. Such a composition gives liquid thermal insulation the properties of water resistance, flexibility, lightness and strength. The thermal conductivity of liquid heat insulators is much lower than that of conventional heaters. Several layers of such paint can replace 5 - 10 cm of polyurethane foam or mineral wool.

True, all this is only from the words of manufacturers and sellers, many practical tests have proven the ineffectiveness of such paint as a heater. Its main task is to reduce heat losses on pipes of hot water mains and boilers.

Application of liquid insulation

The problem of freezing corners can be prevented even at the stage of building a house or repairing a new building. In accordance with the laws of physics, the temperature of the inner surface of the corner is always lower than the temperature of the walls that form this corner. Experienced designers say that ideally, the corners of the walls, both external and internal, should be rounded or beveled. Rounding or chamfering only the inner corner (with wall material or heat-insulating plaster) can reduce the temperature difference between the walls and the corner by 25-30%. The same role is played by pilasters on the outer corners of the building. This is not only a well-known architectural technique, but also a way of additional insulation.

You can use interesting design solutions. For example, in the corner of the ceiling, mount a plasterboard box with illumination from ordinary incandescent lamps. Working lamps will heat the air inside the structure, thereby pushing the dew point inside the wall.

Conventional heating can not always cope with its task, especially if the apartment is corner. In such an apartment, both walls are in contact with the street, so the cold penetrates to a greater extent than when the apartment is placed in the middle of the house.

Even heating batteries cannot cope with such a problem. Owners in this case need to properly insulate their home. This can be done both from the outside of the walls, and from the inside. This article will consider the question of how to insulate a wall in a corner apartment from the inside.

Features of the corner room

It is often very cold in corner apartments.

Corner rooms are always more frozen than rooms that are located in the middle of the house. Due to this, heat losses occur, it becomes quite cold in the room in winter, even the appearance of dampness, mold and other troubles is possible.

In corner rooms, 2 batteries are often installed to maintain the required temperature, but walls can freeze through. Condensation appears on it, which leads to the following troubles:

Avoiding such problems and being in a warm room in the winter will help. Before starting work, you need to determine and choose the right materials to be used.

For insulation today there are a lot of materials, but they are all designed for different jobs.

Some are used only for external work, others are used exclusively inside the building.

How to insulate depends on many factors. There are no universal materials, all heaters have their pros and cons. All heaters must be:

1. With high thermal conductivity.
2. Airtight.
3. Absorbent moisture.
4. Eco-friendly.
5. Burn resistant.
6. With high service life.

Name	Description	Advantages	disadvantages
Mineral wool	The most common insulation, which is made from basalt.	It does not lend itself to combustion, and if it comes into contact with fire, it does not emit harmful substances. Easy to install without special skills and experience, the material is plastic.	Mineral wool is quite weighty, and after a while it can be deformed. Susceptibility to moisture.
Styrofoam	Insulation plates are light and safe for humans. The material can be used for indoor and outdoor use.	Low material cost and easy installation. Withstands strong temperature fluctuations and retains its properties in the range from -180 to +80 degrees. The service life is several decades.	May create condensation inside, and therefore not suitable for wood. The heater burns very well.
polyurethane foam	This is a foam that retains heat well, because most of its composition is gas. It is applied from special equipment, sprayed onto the wall.	High noise insulation performance, does not burn. The operating period is measured in tens of years.	Compared to other materials, it has a high cost. Polyurethane foam is applied from special equipment directly to the wall in liquid form, after which it hardens. For insulation, you will need to hire specialists.

Having studied the features of the materials and choosing the best option for yourself, you can begin to insulate the corner apartment. The instructions for working in and at home are described below.

Performing independent installation, you need to carefully lay each layer of insulation. Any mistake can provoke the appearance of mold on the walls.

Insulation of internal walls in a panel house

Lay the insulation panels on the waterproofing layer

To carry out the work, you will need to prepare the walls and gain access to the base. It is recommended to carry out the work before the start of the repair. Sometimes, a reasonable panel house.

If the insulation is carried out after the relevant work, then tiles, wallpaper and other finishing materials are removed from the walls.

The laying of mineral wool is carried out in 2-3 layers, this will allow the seams of the first layer to be closed with a slab of the next layer.

Insulation of internal walls in a brick house

Insulation is mounted on glue

Work in a brick building has some differences compared to a panel house, but the technology is simple and does not require special skills to perform.

Consider the option of wall insulation inside the room using polystyrene foam or:

1. Initially, the walls need to be prepared. There must be plaster on the bricks, if there is no such mixture, then the bricks must be plastered.
2. The walls need to be leveled and all existing defects removed. Further, the base is primed with means to which antiseptics are added, you can use a special primer.
3. Glue for polystyrene foam must be diluted according to the instructions on the package. The finished mixture is applied to the walls using a conventional and notched trowel.
4. Sheets of insulation are glued to the wall and pressed tightly to the base. When insulating internal walls, dowels are not required to fix the plates.
5. The plates are stacked tightly one to the other. There should be no gaps between them. The denser the pressing of the material to the wall and to each other, the better the thermal insulation properties will be. During installation, use a level to bring out a flat plane. For more information on how to insulate from the inside, see this video:

In case of formation of gaps between the plates, they must be filled with mounting foam.

Before starting the insulation of rooms in a corner apartment, it is necessary to select the material depending on the material of the walls.

For brick, the installation procedure and insulation are different from panel buildings.

After reviewing the information in the article, it will be possible to carry out work quickly and without paying for the services of expensive craftsmen.

One of the frequently asked questions by most of us, especially the owners of an apartment in a panel house, is how to insulate a corner room in a panel house.

Warming a panel house from the outside is a necessary measure, since living in a cold apartment does not add comfort and is fraught with health problems. And, most of all, this applies to end (corner) apartments in panel high-rise buildings. At the interfloor joints, cracks are formed over time, through which water easily penetrates into the wall and is absorbed. In winter, the water accumulated in the walls freezes and begins to hit the wall from the inside, making the living space both cold and, moreover, damp.

Getting rid of freezing corners

You can positively solve this problem if you know how to insulate a panel house from the outside and, in particular, an apartment.

Consider how and with what panel houses are insulated. There are several schemes and methods of insulation using various materials.

Particularly acute is the question of how to insulate the corners in a panel house. The corner room, due to its structural specifics, has not one in common with the street, but two, which significantly increases heat loss. In addition, such rooms contain two windows, one for each of the existing external walls. This fact is remarkable only in terms of illumination, but in terms of heat preservation - so-so.

Living in such apartments are trying to solve the problem by increasing the number of heating devices in the room. But, as everyday experience shows, often there are problems with freezing of the corners between the outer walls and, as a result, condensation appears on the wall and the consequences are not long in coming:

• wallpaper goes away;
• walls previously painted with water-based paint are covered with stains, and the enamel peels off in patches;
• the destruction of the plaster occurs, which will cause damage to the main wall;
• a fungus appears, which looks unaesthetic and is harmful to health.

The conclusion suggests itself - you need high-quality insulation of the corner room and it is better not to limit yourself to just improving the corners.

You can insulate a corner room:

• outside;
• from within.

If insulation is not available from the outside, consider the issue of internal thermal insulation. Condensation is a clear “bottleneck” of internal insulation, therefore, it is necessary to protect the main wall from water vapor.

There are currently two known solutions:

• the use of a heater characterized by low vapor permeability;
• protection of the insulation directly with a vapor barrier film;

Who can carry out thermal insulation outside

Insulation of panel walls is best left in the hands of highly professional specialists who have sufficient experience, perform work in accordance with SNiP and following the sequence of technological operations

.

Coordination with the relevant authorities that allow the insulation of the external walls of a panel house is not required if the building is not of historical value.

At the same time, no matter what kind of insulation you use, the material must meet certain requirements, including:

• high degree of thermal conductivity;
• moisture absorption;
• air tightness;
• Fire safety;
• environmental friendliness;
• long service life.

Important: insulation for a temperate climate should be of sufficient thickness - from 8 cm.

Seam insulation

The need for thermal insulation of joints in accordance with the technology will eliminate the appearance of drafts, fungus, and heat losses.

The main prerequisite for the work is a sufficiently long service life of the house - twenty years or more, as a result of which shrinkage and shift of structural elements occurred.

As a result:

• joint filler peeled off or cracked;
• there is a decrease in the temperature in the room during severe frosts;
• there is damage to the plaster layer, peeling of wallpaper and other finishing materials;
• constant humidity is fixed at the junction;
• the occurrence of mold;
• visual signs of the destruction of the seam from the outside.

The design of the interpanel seam

A panel seam is a junction of external enclosing structures, classified into a seam formed at the junction of two or three slabs.

The last type of seam needs an enhanced technological procedure, since it is the most vulnerable.

Today, the insulation of joints directly in houses from panels is made with polymeric materials, which significantly increased the life of the coating.

The following factors influence the choice of insulation:

• climatic zone;
• number of storeys;
• year of construction of the building and its purpose;
• a major overhaul.

Among the widely used heaters:

• polyurethane foam (sealant based on polyurethane);
• filler Vilaterm;
• mineral wool and other soft insulating fibers.

Also, complete sealing of the seam is a common method of thermal insulation. As a filler, plastic solutions are used that penetrate deeply into the structural cavities, and as a filler they are considered: sand, expanded clay, fine gravel.

All work is carried out on a leveled and thoroughly cleaned surface, while the used plate-type insulation materials with a very high coefficient of strength.

How specialists carry out thermal insulation of a panel house from the outside

Insulation of facades is usually carried out by builders-alpinists, it is advisable to contact trusted specialists, the cost varies depending on the number of storeys, it is really coordinated with neighbors.

The technological process, according to which the external walls of a panel house are insulated, affects the following points:

• cleaning the surface of the panels from dirt and falling facing materials;
• sealing visually visible cracks;
• applying a layer of adhesive substance;
• installation of foam sheets;
• fastening them to the wall surface with dowels.

After the glue has hardened, protective profiles and elements are mounted, after which they begin to form an external decorative layer. It takes at least a week for thermal insulation in a panel house of a 2-3-room apartment.

As you can see, if you approach thoughtfully and consistently to the question of how to insulate the walls in a panel house, then there will be no problems.

Often users are interested in: how to insulate a corner apartment in a panel house yourself? If the insulation outside the panel house will be carried out on the ground floor and you are confident in your abilities, then everything is quite possible.

Painting the walls of a panel house

The insulation of the walls of a panel house will not be complete and incomplete if the walls are not painted, as a result, your house or apartment will stand out in an original way from others. At the same time, painting the walls is the final stage in wall insulation, and acrylic paint is used for this procedure.

The painting procedure is as follows:

• the paint is mixed to a homogeneous mass and tinted in a spacious container for better capture of a portion of the paint;
• paint with a roller, which is dipped into a tray with paint, movements are made in one direction;
• the paint is applied in a thin layer to avoid smudges and sagging;
• in hard-to-reach places use a narrow paint brush-flute;
• the paint is applied in 2-3 layers, each subsequent - only after the previous one has dried.

How much will it cost to insulate a corner apartment

Insulation of panel houses is not a cheap pleasure, the number of storeys directly affects the total cost. For residents of the 1st and 2nd floors, this procedure will cost less, somewhere around 200–220 UAH/sq. m of the cultivated area of ​​the facade, already from the 3rd floor - the price is 220-270 UAH (including materials). Not the entire facade is allowed to be insulated, but only one room, at the discretion. In general, to insulate a 2-room apartment S - 48 sq. m (S facade - 28 sq. m) will cost 6.5-7.5 thousand UAH, and three-room 56 sq. m. m (S of the facade - 37 sq. m) - 8.6-10 thousand UAH.

Conclusion

Wall insulation in a panel house from the outside is the best thing that can be done in such a situation for further comfortable living. The successful combination of conventional building materials with innovative technologies will provide a reliable result.

External insulation is more effective than internal insulation, in addition, the original useful area of ​​\u200b\u200bthe apartment will be preserved. Also, there is no need to remount heating, engineering systems, electrical wiring for external thermal insulation. It should be noted that thermal insulation from the outside significantly increases the value of the apartment, a kind of investment in the future.

Owners of corner apartments especially often face problems such as excessive dampness or cold. The heating system does not always work efficiently. Therefore, it is important to know how to insulate a wall in a corner apartment from the inside and minimize energy losses. With the right approach, it will be possible to significantly improve the microclimate in the room, make it more comfortable for living. In this material, we will tell you how to properly carry out the installation of insulation and what is required for this.

The layout of corner apartments in terms of energy consumption for heating is not the most optimal due to the presence of two outer walls. And as a rule, in such conditions, even the presence of additional heating devices does not save residents from the cold. Before the heating season, when the temperature drops sharply outside, the heat begins to quickly leave the room, which is why the apartment becomes cold, dampness and fungus appear. If the walls are not insulated, it will be uncomfortable to be in such a room.

When the central heating is turned on, the situation improves a little, as it gets warmer, but the corner walls can freeze. This leads to damage to the plaster layer, peeling wallpaper. As a result, mold and various types of fungus begin to develop in such places. Such a microclimate causes discomfort and does not have the best effect on the health of residents. Due to dampness and low temperatures, colds are becoming commonplace for many residents of corner apartments.

A bit of theory: dew point

In construction, the concept of "dew point" is used.

The dew point is the temperature at which condensation forms (moisture from the air turns into water droplets). In relation to the enclosing structures of the house, such a point can be located both on the surfaces of the wall from the outside or inside, and in its thickness.

In a period of high humidity and low temperatures, the microclimate of the apartment contributes to the formation of condensate. Due to an incorrectly located dew point, mold and fungus begin to develop on the walls. It is better to insulate them from the outside. This approach will make the walls inside the room warmer and transfer the dew point to its outer edge. This will help get rid of mold and mildew. If it is not possible to insulate the apartment from the outside, then it is allowed to insulate the end wall from the inside. In this case, it is necessary to choose a heater so that the dew point is in the thickness of the supporting structure.

Clear optimum dew point position

Insulating the walls will help make the room warmer and get rid of dampness. The microclimate will become much more comfortable, and residents will not have to worry about their health. However, it is important to properly insulate the room so that the result is as effective as possible.

Which material to choose - mineral wool or foam?

When choosing a heater, you need to take into account the features of the room. Any material must have properties:

• fire resistance;
• environmental friendliness (in the case of internal insulation, this factor plays a key role);
• ability to absorb moisture;
• high properties of thermal insulation and air permeability.

Mineral wool

Mineral wool is made from basalt and is the most popular material for wall insulation. It perfectly retains heat indoors, but easily passes air, which provides good ventilation. The air in the room is always fresh and does not stagnate, which also allows you to get rid of high humidity. The material is highly elastic, which is convenient for installation. However, over time, basalt wool tends to deform, absorbing excess moisture. Therefore, when installing mineral wool, they arrange a crate.

Among other shortcomings, one can note the harmfulness to the respiratory system. When used indoors, the degree of toxicity is not very high, but still the material is more suitable for outdoor decoration. Another disadvantage is the increased weight.

Styrofoam

The main advantages of polystyrene are its cost and high thermal insulation ability. The material is breathable, lightweight and easy to install. It is non-toxic, which makes it great for interior decoration. Light weight will allow all work to be carried out independently without the involvement of builders. Particularly effective for internal insulation. However, there are also disadvantages. Styrofoam is highly flammable, and is also not suitable for insulating wooden structures, since condensation will form on such surfaces.

Features of insulation of corner apartments of a panel house

The installation process of panel wall fencing is different for wall decoration inside or outside the room. Let's take a closer look at the main differences.

The nuances of installing thermal insulation from the inside of the room

In a panel house, with internal insulation, the material must be laid on bare walls, which is why the procedure is best carried out during the overhaul process. Installation work begins with the installation of a waterproofing layer, which is most often a polyethylene film with special breathable membranes. It is best to use a single piece of film on the entire surface of the wall. A metal frame is installed on the waterproofing layer. After installation of the crate, sheets of insulating material are installed.

When carrying out work from the outside of the room, all foreign objects are initially removed from the surface of the walls, their surface is thoroughly cleaned. The crate is installed directly on the surface of the walls. Next, two layers of waterproofing are installed with a layer of vapor insulator between them. Sheets of the main insulation are installed on top. Outside, decorative cladding is performed.

Features of insulation of corner apartments of brick houses

The procedure for insulating brick surfaces is not much different from panel ones. Consider the features of external and internal insulation of such surfaces.

Nuances of internal installation

Styrofoam is most often used for internal wall insulation in brick houses. Before starting installation work, any trim is removed. The surface is carefully plastered, and then treated with a primer. It is very important to apply the primer in an even layer so that after drying, the formation of cracks does not begin.

Insulation sheets are installed on the still wet material. The insulation material is fastened to the construction adhesive. It is very important to pay attention to the components of the composition. The adhesive material must not emit toxic fumes.

Warming from the outside

Mineral wool is most often used for outdoor work. The start of work occurs according to a similar algorithm. On the outside, the panels are protected with an additional layer of primer to resist weathering, and a decorative finish is applied over the protective layer.

A brief overview of foam grades for wall insulation from the inside

In building materials stores, you can see a fairly large assortment of foam plastic brands. Consider the most common of them. Regardless of the brand, there can be two types of labels on the box: “PS” and “PSB”. The first indicates that the material was made by pressing, the second - non-press method.

C-15 is considered a popular brand of foam. This type is made without pressing. Due to its high density, it is excellent for both indoor and outdoor use. However, foam plastic grade S-25 PSB is best suited for warming corner apartments. This is a higher density material that can also be used for floor insulation. Grade S-35 PSB is distinguished by excellent resistance to extreme weather conditions. It is characterized by high fire resistance, as well as the ability to easily withstand mechanical damage. The densest variety is the S-50 PSB. This is a rather expensive material, which is usually used with frequent hail and constant strong winds.

For internal insulation, only the first two options are used.

A brief overview of mineral wool brands for wall insulation from the inside

There are four most popular varieties of mineral wool: P-75, P-125, PZH-200 and PZH-175. For interior work, only the first two varieties are used. Cotton wool P-75 is the lightest and has a relatively low density. P-125 is more rigid and is used for interior decoration in cold climates. The last two types, due to their increased density, are used only for outdoor work.

The best manufacturers of insulation materials are: Isover, Isorok, Ursa, and Rockwool.

Alternative modern heaters

There are many non-standard alternative ways to insulate corner apartments. They are distinguished by the use of modern innovative materials.

polyurethane foam

PPU insulation meets all requirements for vapor barrier, water absorption and the absence of seams. Therefore, even if there is a dew point inside the layer, it will remain “conditional”, since there is no condensation in vapor-tight materials. It turns out from the side of the room a completely sealed heat-insulating layer.

Keramoizol

Keramoizol

Modern building material, which is characterized by increased thermal insulation. Sold in liquid form. For the most effective insulation, 6 layers are laid on the wall in a direction perpendicular to each other.

Astratek is a liquid insulation material. It can be applied to the surface with a sprayer or a brush, and after drying it forms a strong and elastic substance with a porous structure. Such insulation perfectly passes air, but effectively retains heat inside the building.

Liquid thermal insulation using Mascoat as an example

The paint of a well-known American manufacturer has increased thermal insulation properties, and also repels moisture very effectively. Its efficiency is 5 times higher than mineral wool. 1 mm. In terms of efficiency, paints will not yield to a layer of mineral wool half a centimeter thick. It is applied to the surface of the wall in the same way as ordinary paint. It can be used simultaneously for decorative finishing.

polyph

This material is made from a polyethylene base. Its thermal insulation properties are slightly lower than those of the previous options, but the material also has its advantages. A durable polyethylene film made by foaming is covered on the inside with a thin layer of foil. Sheets of paper are glued on top on both sides. Outwardly, the material resembles wallpaper, often used as a preparatory finish before gluing them. The main disadvantage is the possibility of using only for dry walls. It may not be suitable for a corner apartment, since such rooms are characterized by high humidity.

Penofol

Penofol is a combination of polyethylene foam with aluminum foil. This is a whole series of materials (including single-sided, double-sided, laminated, with an adhesive layer). Moreover, it can be used both in combination with other heat-insulating materials, and independently.

Non-standard method of insulation - electric

A new, but quite effective way to insulate walls in a corner apartment is to use the principle of underfloor heating. Panels with electric heaters are mounted indoors on the surface of the walls and connected to the mains. The control unit is installed in a separate accessible place. For proper installation, it is very important to wait for frost, and then turn on the equipment until the walls are completely dry. Only after that an additional heat-insulating layer is laid and a decorative finish is performed.

This method of insulation is very effective, but has one big drawback. In cold weather, you will need to regularly maintain a stable temperature to prevent the formation of dampness and condensation. This will result in additional energy costs. The purchase of an insulation system itself will require considerable costs, and then you will have to pay for regular operation. However, this approach allows you to create the perfect microclimate inside the corner room in cold weather.

What are the conclusions?

The procedure for insulating the walls of a corner apartment is not considered difficult, but it has many nuances. It is very important to choose high-quality material for insulation, which will provide high thermal insulation and a comfortable microclimate in the room. Internal insulation is an easy way to do it yourself, which is why it is more popular. However, if the apartment has high humidity of the walls and the formation of mold on their surface, it is better to call the masters for external insulation. You can also consider using effective and cheap alternative methods.
