Insulation of a panel house from inside the apartment. Subtleties of the process of thermal insulation of interpanel seams. External insulation technology

If you have experienced the purchase or sale of apartments, then you have noticed that buyers do not really like corner apartments or rooms. What is this connected with? Although it is much easier to ventilate such an apartment in summer, the view from the windows opens on two or even three sides.

But there is one significant drawback. Very often, with the arrival of frost, residents of corner apartments suffer from insufficient heat. If the temperature outside is around zero, and heating season has not yet begun, uncomfortable conditions are being created inside such an apartment. It appears, the windows fog up, the floor becomes cold, and the bed becomes damp.

The main reason for this is the presence of three walls that have access to the outside and are therefore subject to greatest influence low temperatures. In winter, even if available central heating, the situation is only getting worse.

The walls can freeze completely, especially in the corners, interior decoration will begin to fall off, mold and mildew will appear. Staying in such an apartment will not only be uncomfortable, but also unsafe, especially for children. After all, they are most susceptible to the occurrence of diseases caused by.

What to do in such a situation? Many people try to install additional heating radiators, but this, most often, does not solve the problem or solves it, but not completely. Dampness moves to the ceiling, forming places where mold accumulates.

What is the right thing to do in such a situation? The best solution is to try to insulate the walls. How can I do that? How to do it? We'll try to figure it out now. What is the best way to insulate the walls of an apartment from the inside? First, let's look at what types exist.

Today, the market for thermal insulation materials is extensive, represented by various products. All of them are divided according to the place of their installation: outside the wall or inside the room.

Each of them has both disadvantages and advantages. When installing any of them, you must strictly follow the manufacturer's instructions.

When buying a heat insulator, you should pay attention to the following parameters:

  • heat conductivity;
  • air permeability;
  • waterproofing properties;
  • environmental Safety;
  • fire resistance;
  • operating time.

Using quality material, you can insulate the corner without any problems. What is the best insulation for walls inside an apartment? What is the best way to insulate walls from the inside?

Minvata

This heat insulator is the most popular; it is made from basalt fiber. It has excellent thermal insulation properties, allows good ventilation air, but does not tolerate excess moisture well. This material has a high degree of fire safety and does not emit toxic substances when exposed to direct fire.

When installing mineral wool, special guides are used, and the installation process itself does not require special effort, since the material is light and elastic. Is it possible to insulate walls with it? But over time, these qualities can cause it to lose its shape.

The environmental component is also ambiguous - the material emits a small amount of harmful gases. Some people do not use it because of the significant weight gained during installation of the structure.

Polystyrene foam insulation

The name speaks about the process of its creation. That is, the material is created by foaming polystyrene under high pressure. The price of such material is quite affordable, it is easy to assemble and install, which makes it a popular heat insulator.

It has good thermal insulation properties, it is environmentally friendly and safe. It can be used for both interior and exterior work. It can be mounted on walls made of any material.

The process is quite simple and not labor-intensive. The advantages include its huge service life. But of course there are also disadvantages.

So, due to poor water permeability, on wooden walls Condensation can accumulate, which leads to their destruction, and it is also highly flammable. The insulation of a concrete wall from the inside can be carried out perfectly using this material.

Extruded polystyrene foam

This material is the most popular insulation. It is elastic and easy to process. The disadvantages include the difficulty in joining sheets.

There is a material on sale in which the edge is made in the form of protrusions, which makes it much easier installation work.

has good moisture resistance, it is lightweight, convenient for installation work.

Use of polystyrene foam

This is an excellent material for insulating apartment walls. It contains more than 95% gas, so it is an excellent heat insulator.

It is distinguished by its low cost, excellent waterproofing, and fire safety. Polystyrene foam is used at any temperature, being an environmentally friendly material.

Application of keramoizol

It's relative new material. It is sold in containers of various sizes, as it represents liquid material. Has excellent thermal insulation properties. Keramoizol is a durable, waterproof and vapor-tight product.

During installation, several layers are applied, and for better thermal insulation- six. The layers are laid perpendicular to each other. This material has proven itself only with the best side.Its only and main disadvantage is its high price.

Penoizol insulation

Thermal insulation material - penoizol is a type of polyurethane and is used in the form of foam. The advantage is quick installation material in brick construction., forming a layer required thickness heat insulator, no seams or joints.

Excellent thermal insulation and waterproofing properties, the material is non-flammable and environmentally friendly. But perhaps its main advantage is the low cost of work, almost two times less than when using conventional materials.

Using Astratek

Asstratek is a suspension; solid particles are represented by various polymers. To apply to the wall, use a spray gun or install it manually with a paint brush. Excellent insulation, just one centimeter of layer is similar to fifty centimeters of a mineral wool slab.

Does not take up the interior space of the room, forms a smooth, uniform surface that requires minimal processing for applying the cladding. The main limiting factor for large-scale application is its high cost.

How to insulate the walls in an apartment from the inside? It's up to you to decide.

How to insulate walls in a panel and monolithic house?

How to insulate walls from the inside? How to insulate concrete wall from the inside? How to do this correctly? To insulate a wall from the inside, consider step by step instructions insulation of walls and partitions in panel house from the inside.

Algorithm of actions:

  • First you need to prepare the walls. To do this, you need to remove furniture, clean the walls from finishing material to plaster. Therefore, this procedure should be combined with repair work in your apartment;
  • next must be done. It is best to use special polymers, but you can also use regular ones. plastic film. It is applied directly to the walls, the places where the strips are fastened are glued. To do this, use construction tape;
  • Next we install the sheathing; you can use both wooden and metal guides. In the first case, the tree must be treated with antiseptics and fire-fighting solutions. When installing the sheathing, the step size must be selected depending on the insulation, so as not to form gaps and voids;
  • then we directly lay the heat insulator, that is, we insulate the walls. It should fit into the openings between the sheathing. Many materials are designed in such a way that during installation they straighten out and fill the entire form, this significantly reduces installation time;
  • installation . By installing it, we protect our insulation from wet steam, which is always present in the apartment. Under no circumstances should these measures be neglected, as moisture will begin to accumulate in the insulation. As a result of this, the product will lose its properties, and all your work will be lost.

The vapor barrier film is laid without gaps or omissions, the joints and cracks are treated with sealants;

  • installation . It is necessary to choose a material suitable for installation in residential premises. When installing sheets, it is important to follow the instructions, and then you should necessary procedures for installation of facing materials.

How to insulate the walls of an apartment from the inside? Insulate a corner apartment in a panel or monolithic house you can by following these six steps.

Installing insulation on brick walls

How to insulate brick walls inside an apartment with your own hands? Corner walls V brick house can be insulated using the same method as in a panel one. Therefore, we will analyze the work of installing material made from polystyrene.

Insulating a wall in an apartment from the inside:

  • clean the walls down to the plaster. If it is missing, then it should be applied. After this, the walls must be leveled, cracks repaired and then treated with a primer;
  • you need to prepare the glue according to the manufacturer's recommendations and apply it to the walls that you will insulate. In the beginning, you can use a regular spatula. You need to apply glue to the walls, then take a notched trowel and go around the entire perimeter again. This is done in order to create uneven surface glue. This promotes better adhesion of the insulation;
  • how to insulate a wall corner apartment from the inside? Next, we take sheets of thermal insulation and begin installing them on the walls. First of all, the very bottom row is laid. We apply the polystyrene sheet tightly and press it through; you do not need to use dowels or other fastening materials. When installing, use a level and carefully join the edges so that no gaps form; if necessary, cut the sheets. Next row it is installed so that the junction of the two sheets is in the middle of the bottom sheet. This will give greater durability to the entire structure.

Watch the surface of the insulation so that no unevenness is formed, because this will bring additional difficulties during final finishing.

  • After you have installed the thermal insulation, you can begin finishing works. If you plan to cover the walls with plasterboard, then some additional work over insulation is not required. If you plan to cover it with a layer of plaster, putty, wallpaper, or paint, then you need to treat it with a primer, then install a mesh of reinforcing fiber. After this, you can begin to apply layers of plaster or putty.

By following these steps, you can insulate corner room from the inside.

Insulation of walls using the “electric floor” method

How to insulate a wall in an apartment from the inside according to this method? Insulation of the apartment from the inside is carried out as follows. First of all, you need to attach the “” sheets to the wall using fastening materials.

After this, we connect the sheets to electrical network apartments. At the very severe frost turn on the system and warm up the walls until they are completely dry. After this, we lay thermal insulation to prevent heat loss. Then you can start tiling the walls.

So, if you decide to insulate the walls of a corner apartment, you need to choose a material based on the type of walls and the price range of the heat insulator. Then it is important to consider the method of installation and subsequent cladding.

You should also pay attention to the following aspects:

  • installing insulation reduces the volume of the room;
  • poorly performed work can lead to mold;
  • For a comfortable life it is necessary to install ventilation.

By strictly adhering to the rules, you can insulate your apartment and create comfort in it. Insulating the walls of an apartment from the inside is a fairly simple process.

AND inside(you can insulate the front, rear, end wall) is carried out according to the instructions. An insulated corner apartment is great because you can enjoy comfort.

Houses built over the last 2-3 decades retain heat much better than buildings from the past Soviet Union. This is especially noticeable in the cold season - “Khrushchev” buildings built from panels or bricks freeze an order of magnitude faster, so they require more insulation materials and heating. Since millions of people live in such houses, the issue of wall insulation is especially relevant for them.

To normalize the microclimate of the room, residents can use one or two methods of thermal insulation:

  • external;
  • internal.

The implementation of the first method is often complicated by two factors:

  • location of the apartment on the upper floors;
  • layout of the living space, in which most of the walls border on the walls of neighboring rooms (it happens that only a balcony can be sheathed from the outside).

The second method is not without a number of disadvantages:

  • inevitable reduction in the usable area of ​​the room;
  • For good insulation the walls will have to be thoroughly prepared from the inside, destroying the usual way of life;
  • temporary relocation of residents is required, especially if work is carried out with materials containing harmful impurities;
  • insulation from the inside reduces the service life of the panel structure, since in winter the wall falls into the zone of negative temperatures.

Nevertheless, internal insulation walls is preferable to thermal insulation from the outside because it saves money - residents do not have to spend money on high-altitude work. They will also spend less on insulation.

Materials for insulating the walls of a panel house

The operation of the apartment is accompanied by a periodic increase and decrease in indoor air temperature.

Consequently, the material must not only be an excellent heat insulator, but also have acceptable moisture-resistant properties.

This requirement is fully met by the two most popular insulation materials, which we will consider. IN Lately Liquid insulation materials are also gaining popularity, but these are already topics for our other articles.

Insulation supplied in the form of foam that hardens after application. It has a low thermal conductivity coefficient, so it holds heated air well in the house. For uniform application and crystallization, formwork must be used. Its role can be played by bars with a cross section of 25×25 mm or slightly larger, placed vertically and horizontally along the wall. The resulting cells (sections) will be evenly filled with polyurethane foam.

Thermal insulation of walls panel house using PPU has several more features:

  • after the polyurethane foam has hardened, an additional layer of waterproofing must be laid (to reduce the amount of condensate formed);
  • impossibility finishing and cladding (you will have to build a second plasterboard wall on top of the polyurethane foam, on which you can apply wallpaper, plaster, etc.);
  • if the previously listed conditions are met, a minimum of condensation will occur, after which it will be discharged to the junction of the wall with the insulation.

The cost of thermal insulation of the walls of a panel house outside or inside using polyurethane foam is high - special equipment will be required, as well as skilled workers. Therefore, consumers prefer the second good material.

Extruded polystyrene foam (foam)

The biggest difficulties when working with the material arise at the installation stage. Foam supplied smooth slabs 100×50 cm or more, so when covering uneven walls its distortion is inevitable. Therefore, it is necessary to carefully prepare the original surface, otherwise air gaps where condensation will penetrate.

Plates are attached to the wall special glue, applied evenly to the entire sheet, and the joints are coated with sealant. The use of anchor connections is excluded - leaky transitions may occur throughout the entire foam layer. It is better to use a T-shaped profile fixed to the floor and ceiling.

Technology of work execution

When insulating, you should adhere to the stages of work described below.

  1. Choice of insulation method (outside/inside; the second is easier to implement).
  2. Calculation of insulated area, purchase of materials; transition to the preparatory stage.
  3. Drying the surface (using heat guns, heaters). The walls are insulated strictly in the warm season!
  4. Old coatings (wallpaper, paint, decor) are removed, the plaster is removed down to the concrete base.
  5. The surface is cleaned of dirt and dust (use a broom or vacuum cleaner).
  6. Treatment interior walls antiseptic.
  7. Priming the original surface (it is better to use a primer deep penetration and apply it in several layers).
  8. Allow the walls to dry thoroughly.
  9. Leveling using special mixtures (those used in finishing bathrooms are acceptable). When drying the plaster, do not use heaters - this way it will acquire normal strength.
  10. Installation of foam plastic. Unlike polyurethane foam, it does not require formwork - the slabs are attached with glue directly to the dry surface. When using polyurethane foam, the insulation is applied a little later after the wooden frame is made.
  11. After completely dry Using glue, the joints of the plates are sealed with sealant.
  12. A second wall with final finishing is applied on top of the resulting structure.

If all steps are completed correctly, an increase in temperature inside the panel house is guaranteed. If the work does not bring results, you will also have to insulate the floor of the apartment.

Range good insulation materials are quite large, but few of them are suitable for panel buildings. Due to the impossibility of thermally insulating the apartment from the outside, residents have to interior work, which are not very complex, effective and do not require special skills or knowledge. Even residents of hopelessly freezing panel buildings can achieve an increase in room comfort if they use the insulation recommended above.

Over time, the walls of a panel house need additional insulation. Unlike brick buildings, when there is a difference in temperature, they can freeze and accumulate moisture, which leads to the destruction of the external facade of the house, the appearance of cracks, mold and other unpleasant changes. Residents may notice that the apartments are cold, despite the presence of heating. To eliminate the consequences of such changes, and to maintain the level of heat inside as much as possible, it is recommended to insulate the panel house from the outside.

Advantages of external insulation

External insulation of the house will not only avoid heat leakage through the walls, but will also protect the facade from further destruction. Using various options decorative design in exterior decoration the house will look new. In addition, insulating walls from the outside has the following advantages:

  • there is no need to evict residents from the house during repair work,
  • increasing the temperature inside the building by protecting walls from freezing and other adverse effects of weather conditions,
  • no resizing interior spaces– the entire living space is preserved,
  • insulation technology strengthens supporting structure panel house, the building becomes more durable and its service life increases,
  • a layer of insulation on the outside acts as additional good sound insulation of the building.

External wall insulation is most effective for panel houses– it is possible to save up to 50% of heat.

Types of insulation

The choice of which material is best to insulate the walls from the outside is influenced by:

  • location of the panel house in a certain climatic region,
  • amount of precipitation, wind strength and speed,
  • allocated budget for insulation of a panel house,
  • other individual factors.

useful in work

The estimate and project for the work is usually Management Company or HOA. A team of industrial climbers directly carries out the insulation process from the outside.

For panel houses, two types of insulation are mainly used:

Mineral wool

For outdoor work, it is convenient to work with mineral wool slabs, which are produced by various manufacturers. She has good performance according to basic characteristics, including thermal conductivity. However, you need to ensure that the mineral wool does not get wet, otherwise it will lose its properties. thermal insulation properties. To do this, a vapor-permeable membrane is laid under the insulation layer, which will protect it from vapors.

When finishing a ventilated facade, condensation from the walls of the house will be removed thanks to air gap and the membrane need not be used.

Styrofoam

It is distinguished by its lightness and simplicity when laying slabs on the wall. Also has good parameters for heat and sound insulation. For outside work, it is important to use a material that does not support spontaneous combustion. Manufacturers mark it with the G1 marking, however, the results of many tests confirm that the foam is flammable, and this name does not meet the requirements of GOST 30244-94. When purchasing insulation, be sure to ask the seller for product certificates.

It is important to know

The insulation of a panel house from the outside is limited by the thickness of the insulating material. The maximum value of the foam thickness for walls is calculated using special formulas, taking into account the average temperatures in a certain climatic region and the purpose of the building (residential, public, industrial).

Stages of the facade insulation process

Depending on the chosen insulation method, installation will vary. There are two main technologies:

  1. Wet Facade
  2. Ventilated facade

The process of insulation using the “wet” method is described below.

Preparing the wall surface

It is necessary to carefully prepare the surfaces of the facade of the house in order to insulate it efficiently. Each wall is leveled, cleaned of various deposits, voids and cracks are sealed, especially paying attention to the joints of the panels. If necessary, they put a sealant in them, coat the cracks with special mastics.
Unevenness of the wall surface is allowed within 1 - 2 cm, but no more.
After cleaning and processing the joints, the walls are left to dry. Next, they are coated with a universal primer using a roller or sprayer.

Installation of insulation

Attaching thermal insulation material to walls is possible in three options:

  • on glue,
  • for fasteners (dowels, plastic nails),
  • combining glue with fasteners.

The video shows in detail the method of attaching foam plastic using dowels for thermal insulation.

For example, polystyrene foam is fixed using a combined method from the first floor to the upper ones. The bottom is installed starting bar, from which they begin to glue the insulation. In this case, the glue is carefully applied to the walls with a spatula, filling the existing unevenness. Then the foam sheets are pressed tightly onto the treated surface. The evenness of the rows of insulation is checked with a level. It is possible to correct minor errors before the adhesive base sets. Now you need to wait 2 - 3 days for the glue to dry completely and for the insulation to adhere well to the walls. Next, the foam plastic is additionally secured with dowels - 4 - 5 pieces per sheet. Holes for fasteners are made with a hammer drill.

The second and subsequent rows of foam sheets are laid in a checkerboard pattern so that the joints of adjacent layers do not coincide. All seams between the insulation and cracks from fasteners are filled with a special polyurethane foam, designed specifically for the installation of foam plastic, in order to minimize the likelihood of heat leaks. This foam is produced in cylinders and is best applied with a special gun. The excess and remaining foam is cut off after drying.

Pinning the grid

Polystyrene foam is a fairly fragile material, so it is reinforced to give strength and rigidity to the insulation elements. To do this, a special stable mesh is installed on the outside of the foam sheets. It is convenient to cut it into separate pieces of the same size and overlap it in small fragments. A layer of special adhesive solution For facade works, and the mesh is pressed into it. Then another one is applied to level it out. adhesive layer. After installing the mesh over the entire house, wait for the glue to dry in order to treat the surfaces with sandpaper to remove smudges of the solution and unevenness during the fastening process.
The reinforcement provides mechanical stability for the final decorative covering panel house.

Finishing

After insulation external facades, as a rule, are decorated with decorative plaster. For the best adhesion of materials, the general layer of thermal insulation is primed again.
In addition, for residential apartment buildings often use the technology of suspended ventilated facades. The thermal insulation layer has already been completed - all that remains is to install the outer cladding with a ventilation gap.

Today it is offered wide choose materials for exterior finishing in a curtain façade system:

  • metal products (corrugated sheeting, siding, facade cassettes),
  • aluminum composite panels,
  • slabs made of porcelain stoneware, natural or artificial stone.


Each of them can be selected according to its external structure, color scheme and other characteristics.
Ventilated façade technology not only protects the walls of a building, but also makes it possible to implement a variety of design ideas and solutions.
To attach a ventilated facade, an additional frame will be required.

The process of insulating panel houses can be carried out during their reconstruction or major renovation. If your choice falls on the “wet” facade technology, it is advisable to plan work in the summer or at temperatures above 5°C. When using ventilated facades, installation can be done all year round.

The thermal insulation properties of concrete panel houses leave much to be desired, since they are very hot in summer and cold in winter, which leads to increased energy costs for heating. This problem can be solved by thermal insulation of the walls, however, this issue must be approached competently. Therefore, next I will tell you how to properly insulate a panel house.

Insulation options

Thermal insulation of a panel house implies, first of all, insulation of the walls. Moreover, it is advisable to perform this operation outside, in which case the walls will be really warm. If this is not possible, for example, if you do not have permission to change appearance facade or adjacent to the apartment unheated room that cannot be insulated (elevator shaft, entrance, etc.), then insulation can be done from the inside.

In all other cases, it is better to refuse internal insulation for the following reasons:

  • internal insulation takes away useful space in the apartment;
  • after thermal insulation, the walls stop heating altogether, which can lead to the formation of cracks;
  • forms on the surface, which can lead to the formation of mold;
  • there is no possibility of insulating the ceiling, which is adjacent to the cold walls and serves as a cold bridge.

Thus, insulating walls from the inside can be considered only as a last resort. However, below I will talk about the nuances of thermal insulation in both cases.

External insulation

First of all, let's look at how to insulate walls from the outside. This process can be divided into several stages:

It must be said that almost every stage contains its own nuances, on which the final result depends. Therefore, all work must be performed with special responsibility, from beginning to end.

Preparation of materials

First of all, you need to decide on the insulation. For these purposes, the following materials are most often used:

  • expanded polystyrene (foam plastic) - quite cheap and lightweight material. Disadvantages include fire hazard. It should be noted that for external insulation, foam plastic with a density of at least 18 kg/m3 can be used;

  • mineral wool is an environmentally friendly and more durable material that resists the combustion process. The disadvantages of mineral wool include its higher price, as well as the inconvenience of working with it - if it gets on the skin, mineral wool fibers cause irritation.

The density of mineral wool for facade insulation must be at least 85 kg/m3.

The thickness of the insulation must be at least 100 mm. In northern regions, it is better to use 150 mm thick insulation.

In addition to insulation, you will also need the following materials:

  • adhesive for insulation - as a rule, it is selected depending on the type of thermal insulation material, however, there are also universal compositions;
  • inter-seam insulation for panel houses - most often polyurethane foam is used for these purposes;
  • plastic umbrella dowels;
  • universal primer;
  • fiberglass reinforcement mesh;
  • aluminum perforated corners;
  • decorative facade plaster;
  • facade paint.

Preparing the walls

So, before you insulate the walls from the outside, they need to be prepared. This is done as follows:

  1. start by removing the old coating. As a rule, panel houses are covered with tiles, which begin to lag over time. In this case, the tile must be dismantled;
  2. then the surface of the walls should be cleaned of dust and dirt;
  3. Next you need to insulate the seams. Often, in order to insulate joints in panel houses, they must first be expanded.
    After this, be sure to clean them from dust and moisten them. The prepared seams should be filled with polyurethane foam. You can also use putty for these purposes;
  4. After the foam hardens, it must be cut off so that it does not protrude above the surface of the walls.

If work needs to be done at height, it is better to entrust it to specialists who have all the necessary climbing equipment.

After preparing the walls, you can begin installing the insulation.

Installation of insulation

Insulation installation instructions are as follows:

  1. First of all, you need to dilute the glue in water and mix it thoroughly. How this is done is indicated on the packaging with the composition;
  2. then the glue must be applied to the insulation using a notched trowel. If the surface of the walls is uneven, it is better to apply the glue in lumps, which will allow you to adjust the position of the insulation relative to the wall;

  1. Now the insulation needs to be glued to the wall. Start working from the corner, performing installation in rows from bottom to top, and thermal insulation should be positioned so that the ceiling is also insulated.
    To glue the insulation, press it against the wall and check the position building level;
  2. then glue the insulation on the opposite side in exactly the same way, and stretch the twine along the first row. The stretched thread will serve as a beacon for the remaining thermal insulation slabs;
  3. then glue the remaining insulation boards of the first row along the lighthouse;
  4. then the second row of insulation is installed according to the same scheme. The only thing is to position it offset relative to the first row, i.e. according to the principle of brickwork.
    If you are insulating a corner room from the outside, then it is also necessary to ensure that the insulation is bandaged at the corner, as shown in the diagram below;

  1. According to this principle, the entire surface of the walls is insulated;
  2. Now you need to install the dowels. To do this, drill holes directly through the insulation to the required depth, then insert “umbrellas” into them and drive in the expansion pins. Keep in mind that the dowel heads should be slightly recessed into the insulation.

Pay special attention to the location of the dowels - they should be installed between the joints of the insulation at the corners, as well as one - two dowels in the center of each insulation;

  1. To complete the work, it is necessary to paste over the window openings. To do this, cut the insulation into panels about 3 cm thick and glue them around the perimeter, thus creating slopes.

To cut the insulation, use a regular wood saw.

This completes the insulation installation process.

Preparation for reinforcement

Before proceeding with reinforcement, it is necessary to prepare the surface of the thermal insulation by performing the following steps:

  1. use the long rule by applying it to the walls on different areas. If lumps are found, they must be rubbed with a special grater.;
  2. Also at this stage, make sure that all the dowels are recessed into the insulation, otherwise they need to be finished off. If it is not possible to deepen the dowel, it must be cut off assembly knife and install a new one nearby;
  3. after that, glue the perforated aluminum corners to all external corners and slopes, using the same glue for the insulation;
  4. if there are gaps between the insulation boards, they must be filled with small pieces of thermal insulation or special foam;
  5. To complete the work, apply glue to the heads of the screws, as well as the joints of the insulation boards.

In the end it should be Smooth surface walls that can be plastered.

Reinforcement

Insulation reinforcement is carried out as follows:

  1. start work with slope reinforcement. To do this, cut the mesh into sheets required sizes, taking into account that it should be located with a turn at the corners and an overlap of about 10 cm;
  2. after that, apply glue to the surface of the slope a few millimeters thick and attach the mesh to it. You need to run a spatula across the canvas so that the mesh sinks into the glue. Work as carefully as possible to ensure a smooth surface in the end.;
  3. after the surface has dried, the glue is applied again and carefully leveled with a spatula, as if you were puttingty;
  4. Now the walls should be reinforced using the same principle. As a result, you should have a smooth surface suitable for applying decorative plaster.

Padding

Before covering the facade with decorative plaster, the surface of the walls should be treated with a primer. This is done like this:

  1. shake the façade thoroughly and pour it into a special tray for a paint roller;
  2. then dip the roller into the tray and apply it to the wall. Try to do the work carefully so that there are no soil drips;
  3. After the surface has dried, the primer must be applied again.

Now you can start applying decorative plaster.

Plaster

Decorative plaster is applied very simply and quickly:

  1. First, dilute the mixture in water and stir. Detailed instructions available on the packaging;
  2. Next, use a narrow roller to roll up the plaster onto a small trowel or a wide spatula and apply it evenly to the wall. thin layer. The thickness of the layer depends on the size of the filler fraction;
  3. When the plaster on the wall begins to set (thicken), the surface needs to be rubbed with trowel to give it a certain texture. Malka can make circular or reciprocating movements in a vertical or horizontal position;
  4. According to this principle, the entire prepared surface of the facade is covered.

Apply within one wall decorative plaster necessary in one go, i.e. without interruption. Otherwise, the transition border will be noticeable.

Painting

The final stage of work is painting, which is carried out as follows:

  1. The paint needs to be shaken and, if necessary, tinted. You can find out in detail how coloring is performed on our portal;
  2. after this, paint must be poured into the roller tray and the roller itself must be dipped into it;
  3. now apply the coating in a uniform thin layer, avoiding its spreading and splashing;
  4. hard-to-reach places should be touched up with a paint brush;
  5. After a few hours, when the paint has dried, the procedure must be repeated again.

At this point, the work on external wall insulation is completed.

Internal insulation

Insulation from the inside can include not only thermal insulation of walls, but also floors and even ceilings. Therefore, next we will consider the nuances of insulation of all these surfaces.

Floor insulation

To insulate the floor you will have to concrete screed on top of the insulation. This work is carried out in the following sequence:

  1. first of all, prepare the floor - clear it of debris, if necessary, remove the finishing coating;
  2. then cover the floor with waterproofing film, placing the sheets overlapping and folding over the walls;
  3. Then thermal insulation is laid on top of the waterproofing. This can be either mineral wool or polystyrene foam;
  4. then another layer should be laid on top of the thermal insulation waterproofing film. To ensure maximum tightness, seal the joints with tape.;
  5. Now you need to pour a screed on top of the insulation standard scheme. The only thing is that you should not use reinforcing mesh so as not to damage the waterproofing. It is better to perform reinforcement by adding special fiber to the solution.

If you don’t want to deal with wet work, you can do a dry screed yourself. To do this, cover the floor with a layer of expanded clay, level it along the beacons, and lay special panels for dry screed on top.

Wall insulation

Insulate cold wall from the inside it is best to use a dry method. This operation will be performed in the following sequence:

  1. First of all, prepare the wall for insulation - clean it from old decoration, if necessary, seal the cracks with putty. In addition, be sure to treat the surface with an antiseptic to prevent mold;
  2. A vapor barrier film must be attached to the prepared wall. To do this, you can use screws with wide heads or even wooden slats;
  3. Now you need to mount a frame for attaching drywall or other finishing material (plastic panels, lining, etc.). To do this, as usual, attach the guides to the floor and ceiling, and the distance from them to the wall should be a centimeter greater than the thickness of the insulation;
  4. then insert the posts into the guides and secure them with brackets. At this stage, check the position of the racks with a building level. The distance between the racks should be such that the insulation fits closely into the space between them, leaving no gaps;

  1. Next, the space in the resulting frame needs to be filled with insulation. The latter should fit tightly not only to the racks, but also to the ceiling and floor;
  2. Now you need to attach another layer of vapor barrier film to the frame. To do this, you can use profiles that are attached to the frame with self-tapping screws;
  3. At the end of the work, attach it to the frame using self-tapping screws finishing material. On our portal you can find detailed information about how to install drywall, plastic panels and other finishing materials.

If you want to completely insulate the room, you need to place thermal insulation on the ceiling. The installation principle remains the same, with the only difference being that the frame is attached to the ceiling, not the walls.

If your apartment has a balcony or loggia, the room can also be insulated and even heated. In this case, you can use the additional space as living space.

Before insulating a balcony in a panel house, all surfaces must be treated antifungal composition, as mold often appears here.

This is, perhaps, all the information regarding how insulation of panel houses is carried out.

Conclusion

Insulation of panel houses, as you can see, has quite a lot of nuances that must be taken into account during the work process. However, in general, this procedure is quite simple, which every home craftsman can handle. The only exception is those cases when the work needs to be done at height - do not risk your life, it is better not to spare money and seek help from specialists.

Recently, with the constant increase in energy prices, people are trying to insulate their apartments. This procedure really allows you to save on heating and make your home more comfortable, but at the same time it must be performed correctly so as not to encounter a number of problems later. Therefore, in this article we will look at how to insulate the walls of an apartment inside, and whether there is any point in doing this at all.

Is it worth insulating walls from the inside?

It is, of course, much easier to insulate walls from the inside than from the outside. However, I would like to point out right away that this is far from The best decision for several reasons:

  • After installing thermal insulation, the walls will stop warming up altogether, as a result of which will form between them and the wall. This in turn can lead to the formation of mold and even cracks on the walls;
  • when the insulation is located from the inside, it is not possible to insulate the ceiling, as a result the ceiling also turns out to be “cold”, and condensation can form on it;
  • Insulation from the inside takes away living space. In a large apartment this, of course, will be practically unnoticeable, but for a “Khrushchev” apartment, where everyone counts square centimeter, effective area decreases significantly.

This raises the question - why carry out internal insulation at all if it has so many shortcomings? The fact is that it is not always possible to insulate the walls from the outside. For example, if the facade of your house faces a central city street or square, then local authorities are unlikely to allow you to change its appearance.

In addition, sometimes it is not possible to carry out external insulation for technical reasons, for example, if the wall is adjacent to an unheated elevator shaft. Thus, it makes sense to insulate the walls from the inside in an apartment in the following cases:

  • if it is not possible to place the insulation outside;
  • if internal insulation is used as an addition to external insulation. Even if the additional insulation on the walls is quite thin, the inside of the home will become much more comfortable.

After insulating the walls from the inside, it is necessary to ensure high-quality ventilation premises, since the apartment essentially turns into a large sealed thermos. This in turn will lead to increased humidity and deterioration of the microclimate.

In other cases, it is better to insulate the apartment from the outside.

Insulation technology

The process of insulating walls with your own hands from the inside includes several stages:

Each of these stages has its own nuances, which we will look at below.

Preparation of materials

Insulation work must, of course, begin with the preparation of materials. Since people are often interested in what is the best way to insulate a home from the inside, I will say a few words about insulation.

Basically you can use any thermal insulation material, since their degree of thermal conductivity differs slightly. However, it should be borne in mind that the material will not be located in the home, but outside it. Therefore, it is better to refuse polystyrene foam, but mineral wool is good decision– this heat insulator is much more environmentally friendly, and also fireproof.

In addition to insulation, you will need the following materials:

  • vapor barrier film - prevents moisture from penetrating into the insulation. If it is not used, the insulation will become saturated with water, which entails a number of negative consequences;

  • material for mounting the frame - this can be wooden beams or boards. However, most often they use a regular profile for installation. In this case, you will also need brackets and guides;
  • plasterboard or other material for covering the frame (lining, plastic panels etc.)

To purchase all these materials, you need to first calculate the square footage of the walls. Knowing the price of each material, you can calculate the costs of internal insulation in advance.

Preparing the walls

So, we figured out how to insulate the walls of an apartment from the inside. Now let's get to work.

As mentioned above, before insulating a wall from the inside in an apartment, it must be prepared. This is done as follows:

  1. first of all, it is necessary to remove the old covering from the wall - wallpaper, tiles, etc. If the wall is covered with gypsum putty or plaster, it is also advisable to remove it.
    As mentioned above, moisture will form between the wall and the insulation, as a result of which the plaster will become wet, and this will not lead to anything good. You can remove the plaster using a chisel and hammer or a hammer drill turned on in impact mode.

  1. then be sure to treat the wall with antiseptic agents that will prevent mold from occurring. Instructions for using drugs are usually included on the packaging.

To achieve the maximum effect from insulation, it is necessary to insulate the ceiling, i.e. ceiling that will be adjacent to the frozen wall. This can be done using the wet method - gluing mineral wool slabs and additionally securing them with dowels. The surface of the insulation is plastered; on our portal you can get detailed information on how this is done.

This completes the preparation process.

Arranging a ventilation gap

The process of arranging a ventilation gap is carried out at the stage of waterproofing the walls. It should be noted that many construction sites offer thermal insulation from the inside without a ventilation gap.

The big disadvantage of such a scheme is that moisture inevitably forms between the wall and the insulation, which does not go away, which leads to the destruction of the wall. Therefore, it is better to refuse its implementation.

The arrangement of the ventilation gap is carried out in the following sequence:

  1. attach to the walls wooden slats about two centimeters thick. They can be placed horizontally in increments of about a meter. You can attach the slats to the walls with dowel nails.
    The slats must be pre-treated protective composition so that they do not rot in a humid environment;
  2. then you need to make several holes in the wall so that ventilation gap have worked. To do this, drill holes with a diameter of about 20 mm. To prevent the holes from becoming clogged, they must be protected with a mesh;
  3. then a vapor barrier film is attached to the resulting sheathing. Moreover, it should be positioned stretched so that a ventilation gap is formed between the wall and the film.

To drill holes from the inside in a panel house for dowel-nails, you should use a hammer drill with a Pobedit drill.

Frame installation

The frame is vertical racks, which are located in increments equal to the width of the heat insulator slabs. To ensure that the insulation fits securely to the studs, the step between them can be made even a centimeter less than the width of the insulation.

The frame assembly process is as follows:

  1. First of all, mark the walls according to which the racks and guides will be located. It should be noted that the distance between the wall (vapor barrier in our case) and the guides that will be mounted on the ceiling and floor must be no less than the thickness of the heat insulator so that the insulation can fit inside the frame;
  2. Next, brackets are attached to the vapor barrier slats according to the markings, which will hold the racks. Multiple brackets should be used for each rack. For installation of the latter, self-tapping screws are usually used;
  3. then guides for the racks are attached to the floor and ceiling. They must be located exactly opposite each other so that the racks stand vertically. Therefore, before installing them, you should make sure that the markings are accurate;
  4. Next, the racks are inserted into the guides and fixed with brackets, as shown in the diagram above.

For cutting metal profile You can use special metal scissors.

The same principle is used to install a frame made of beams. The only thing is that in this case, guides are not used, so the racks are installed simply according to the markings.

Installation of insulation is extremely simple - if the racks are positioned correctly, then the mineral wool slabs are simply inserted between them, and no additional fixation is required. The only thing to avoid cold bridges is to fill the space between the wall and the studs with insulation.

To do this you can cut mineral wool strips of the required sizes. You can cut the slabs with a regular hacksaw.

Mineral wool fibers getting on the skin and especially the eyes cause severe irritation. Therefore, when working with it, use personal protective equipment.

If gaps form between the mineral wool slabs, they must also be filled with insulation. In addition, it is necessary to ensure a tight fit of the mineral wool to the floor and ceiling. I note that these, at first glance, little things should not be neglected, since the effectiveness of insulation largely depends on them.

After the insulation has been laid, another layer of vapor barrier should be secured to the frame. If the frame is wooden, then you can use a construction stapler to fix it.

If the frame is metal, the vapor barrier can be temporarily fixed with tape. Subsequently, the film will be secured with the covering material.

On forums, people are often interested in how to insulate a wall from the inside in a corner apartment? In fact, the technology is no different.

Frame covering

As a rule, the frame in an apartment is covered with plasterboard. Therefore, finally, I will briefly describe the technology of its installation and further finishing:

  1. work should begin by cutting drywall into sheets of suitable size. To do this, apply markings to the sheets, then cut the cardboard on one side along the marked line with a mounting knife, then break the sheet, and then cut the cardboard on the other side;
  2. the prepared sheets should be attached to the frame using self-tapping screws, which should be located at a distance of 5-10 cm from each other. The caps of the screws must be recessed;

  1. then at the joints of the sheets you need to cut a chamfer 5 mm wide. If the end is rounded, there is no need to cut the chamfer;
  2. then a special self-adhesive mesh is glued to the seams between the sheets;

  1. then the heads of the screws and the joints between the sheets are covered with gypsum putty;
  2. After this, the entire surface of the walls is puttied. On our portal you can find detailed information on how to properly perform puttying;
  3. then the surface is polished with a special grater, onto which a mesh is put:
  4. after this another layer is applied finishing putty and final sanding is performed.

Sanding must be done in bright light. In this case, you will see all the flaws that need to be eliminated.

This completes the process of covering and finishing the wall. Now you can paint it or, for example, put wallpaper on it.

If lining is used as cladding or wooden panels, then they are simply attached to the frame with self-tapping screws. Accordingly, it takes much less time to cover.

Here, in fact, is all the information on how to insulate the walls of an apartment from the inside with your own hands.

Conclusion

I told you how to insulate walls inside with minimal negative consequences. Therefore, do not try to simplify the process and deviate from the technology outlined above. Compliance with it will allow you to make your apartment truly warm and cozy.
