Technology of insulation of the facade of a panel house. Insulation of the facade of a panel house - what you need to know? How to insulate a multi-storey panel house outside the wall

A few years after the construction of a panel house, the residents have a question: how to properly insulate it? Over time, the ability of concrete slabs to retain warm air and prevent the penetration of cold air is significantly reduced. Heat loss begins not only through windows, but also through walls. In winter, this situation begins not only to bring some discomfort to the existence of the family, but also to be very annoying. There is only one way out of this situation - the insulation of the walls of the panel house.

Insulate the facade of a panel house

If you insulate the room from the outside, you can avoid heat loss through the wall, which will also serve as an obstacle to the destruction of the structure. In addition, the use of various finishing materials will give the house a new, more modern look. External insulation has other advantages:

  • tenants can continue to live in the house during construction work;
  • the temperature inside the building is increased by the use of thermal insulation material;
  • the dimensions of the room remain the same;
  • the design of the room becomes stronger, the service life increases;
  • thermal insulation plays the role of soundproofing material, reducing the likelihood of noise entering the room.

Insulation of a panel house from the outside is very effective, because it allows you to reduce heat loss and save on paying for the coolant. In some cases, the amount of savings reaches half the usual cost.

Necessary materials and tools

Keeping warm without the use of additional electrical appliances can be very effective. For a properly organized process, there are various types of insulating materials. The most popular are:

  • mineral wool;
  • drywall;
  • Styrofoam;
  • plaster.

The materials used in the work must certainly be of high quality. Otherwise, getting a positive effect will be a big question. Some of the materials presented on the modern construction market are designed specifically for use in outdoor conditions.

How to insulate walls

There are two technologies by which the walls are insulated:

  1. Wet facade.
  2. Ventilated facade.

For insulation using the materials described above, use the first method. To organize a ventilated facade, a system for creating a metal frame is used, on which finishing material is subsequently attached.

The method by which the reinforcement is carried out with finishing materials in case the "wet" method of protecting facades is chosen is quite simple. The wall to be treated is necessarily treated with mastic, after which it is left to dry.

The surface, dried after processing the joints, is ready for further work. She will have to be covered with a primer, which can be done using both a roller and a special sprayer.

On a pre-prepared wall, heat-insulating material is to be fixed. This can be done with glue, fasteners (nails, dowels). A combination of mounting methods is possible.

Floor

High-quality insulation of a panel house begins with floor protection. This issue is especially relevant for citizens living on the first floors. In most cases, they have to resort to such events.

To reduce heat loss through the floor, the builders provided for the construction of a lag on the floor of an apartment located on the 1st floor of a multi-storey building. In the cells, which are organized by the intersection of the elements of the wooden structure, insulating materials are laid. It can be either foam plastic or mineral wool, or more exotic material options: expanded clay or sawdust. (You can read more about the types and brands of expanded clay).

Modern building and finishing materials are presented in such a variety that each owner of the premises will find his own version of floor insulation. In addition, new materials are constantly appearing, but they have managed to prove themselves perfectly. This can be said about such types of heaters as polyurethane foam or penoizol. The use of even a thin 30 mm layer of these materials will significantly reduce heat loss.

You can learn how to insulate the floor in a room with your own hands quickly and efficiently by watching the video.

seams

A large amount of useful thermal energy is lost in a panel house through seams. This problem can also be easily solved by processing them. Monolithic solution of the distance between the plates allows you to fill the existing voids in the seams and contributes to the insulation of the entire structure as a whole.

The choice of mixtures that can be used to fill the seams in a panel house involves both their self-preparation and the purchase of a finished product. One way or another, these compositions can be filled with foam balls to delay the flow of heat, and with particles of air to keep the heat trying to get into the street.

If the distance between the seams is large, then you can fill it with a soft insulating fiber. In the role of it is the well-known mineral wool. Its key features are as follows:

  • high compression ratio;
  • possibility of use in work at negative air temperatures;
  • ease of use, which consists in ease of installation and the absence of a list of tools, without which the work would be impossible.

Mineral wool fibers are volatile, and they can also release formaldehyde components. These facts lead to a decrease in the frequency of use of this material in the insulation of panel joints. More practical in such a situation is stone wool, which is safe for the health of residents and has fibers that do not break.

Styrofoam

Modern insulation, which is used very often. It is quite economical, easy to use and easy to install. Independent installation work is possible even for an inexperienced person, and work on high floors requires the involvement of industrial climbers.

After the plates on the outside have been processed, insulation can be attached to them. If foam is used as this material, then you should remember the recommended thickness of the material. It should not be less than 50 mm. On the inside of each sheet should be applied glue, which is specially designed for work of this kind.

The laying of insulation should not be accompanied by the formation of cracks, because the work will not make sense: precious heat will escape through them. This can be avoided only with the competent organization of installation work and the use, in addition to glue, and other types of fasteners.

Mineral wool

Many manufacturers work with this type of insulation, like mineral wool. It is quite effective, but there are certain nuances when working with this material. So, cotton wool should not get wet, otherwise its thermal insulation properties will be lost. To avoid the accumulation of moisture in the layers of insulation, before installation, the material is protected by laying vapor barrier materials.

The membrane may not be used if such a method of insulation as a ventilated facade is chosen. In this case, moisture will be removed due to the air gap.

Drywall

The issue of room insulation must be taken seriously. In certain climatic conditions, wall insulation with mineral wool is considered quite justified. In this case, you can not do without drywall sheets.

In this way, it is possible to insulate not only facade surfaces, but also living quarters: balconies, loggias, walls inside technical rooms. At the same time, you should be more careful with the amount of mineral wool used. Its excess will not only not make the apartment warmer, but will also contribute to excessive cooling.

Preparatory work

Turning an apartment into a room that meets all the requirements for thermal insulation is possible. To do this, it is necessary to correctly organize measures for warming. The preparatory stage also plays a big role. It needs:

  • process the joints between the plates;
  • carefully seal the gaps;
  • clean all cracks from construction debris;
  • seal all parts of the building that will be in contact with the insulation;
  • insulation of large gaps with mineral or stone wool.

If the cracks were additionally insulated, a layer of mastic must be placed on top.

How to insulate a panel house. Step-by-step instruction

The instructions for warming a panel house contain the following steps:

  • the choice of material and its quantity depending on climatic conditions and purposes;
  • purchase of materials and construction tools;
  • drying walls with a heat gun;
  • removal of possible finishes from the walls to be insulated;
  • applying an antiseptic composition to surfaces that will soon be covered;
  • applying a primer; (how to properly apply a primer, see the article Wall Primer - Surface Preparation)
  • sealing of seams, if necessary - additional insulation;
  • installation of insulation (using glue, plasterboard sheets and a metal frame);
  • the use of metal mesh for additional reinforcement;
  • insulation trim if necessary.

The beginning of work should fall on the bottom of the wall, because that is where the starting bar is installed. Glue is best applied with a spatula.

Experts with extensive experience in installation work advise:

  • to insulate the camp of a panel house in the summer;
  • with external insulation, it will be useful to insulate the inner parts of the wall;
  • the best option would be to use seamless technologies, as this will save additional heat;
  • some modern technologies are very convenient, for example, the use of foamed polyurethane for insulation, which can even be applied by spraying;
  • do not forget about the use of vapor barrier;
  • the selected material should not be afraid of moisture.

Compliance with the rules for installing heat-insulating materials will not only make the room warmer and more comfortable, but also significantly extend the life of the walls, because an additional layer of coating protects them from destruction.


People who live in prefabricated houses often notice moisture on the walls, fungus, peeling wallpaper, mold and even freezing of the walls in winter. This may be, since panel houses are poorly cleaned from temperature changes. External insulation of the facade helps to solve this problem.

Types of insulation

Of the many materials for facade insulation, the following heaters have proven themselves well:
-Styrofoam;
-mineral wool;
-extruded polystyrene foam.
All these heaters are united by one property - low thermal conductivity.

Insulation installation technology

Wall preparation

Before starting work on insulation, it is necessary to prepare the walls. Align all the irregularities, clean and close up the walls of the panel house. If paint or plaster crumbles, it must be removed. We pay attention to the seams between the panels, in case of defects, everything must be corrected.

Insulation installation

The most optimal insulation price / quality is foam, so we will further describe the technology of its fastening. There are three technologies for fixing foam: on dowels, on glue, combined. The most effective combined mounting method is dowels and glue together.
Start gluing from the bottom up. At the very bottom on the facade, we fix the starting bar on uneven walls; glue can be thrown with a bucket; if the walls are even, then glue can be applied with a comb.

Fill in the seams carefully. It is not necessary to apply glue to the foam sheet. So that there are no voids under the insulating material, fill all the pits on the wall with an adhesive solution. Since voids can be a "conductor of cold." After applying the adhesive, it is necessary to attach a sheet of foam, align and press it against the wall. For further work (puttying, painting) it is necessary to wait a few days, this is necessary for the glue to dry completely and shrink. Only then continue to work.

Fasteners are used for mounting foam on dowels - this is a plastic dowel with a large round cap, consisting of a plastic sleeve and a galvanized nail, which is driven into the sleeve.


To fix the foam with dowels, it is necessary to drill a hole around the perimeter of the sheet and in the center. The depth of the hole should be 2 cm more than the dowel itself, if this is not done, the dowel will not press the foam. The styrofoam should fit snugly against each other.

If gaps suddenly form between the insulation and they can be filled with mounting foam, which can be cut off after drying.

After installing the foam sheets, the dowel caps and the seams, we putty with glue, we rub the defects that have arisen after drying with an emery net.

Mesh wall cladding

Styrofoam material is brittle and brittle; it must be reinforced. Strengthening is done by gluing reinforced mesh.
To insulate the apartment from the outside, a special mesh is used; it resists all atmospheric phenomena, does not tear or stretch under the influence of external factors.

It is necessary to start gluing the mesh from the corners and only then the main part of the surfaces. On sale there are special mesh with corners, it will greatly simplify your work without additional problems.

To make it easier to glue the mesh and cut it into fragments. Pieces of mesh measuring a meter by a meter or a meter by two can be glued in small sections.

After the glue has completely dried, it is necessary to treat the surface with plastic floats.

After the entire surface has been sanded, all excess mortar has been removed, it is necessary to apply a leveling layer and proceed to the final finish.


The same technology of insulation and mineral wool. This material is a little more expensive but it has many advantages.

This is all you need to know about finishing and insulating a panel house from the outside. Today, many construction companies offer their qualified services (we recommend teplodim.info). But if your hands are growing from the right place, there are scaffolding or you live on the ground floor, you can do the installation of the insulation yourself.

Panel houses have always been considered not too “warm”, since the internal and external walls in them are rather thin. It is for this reason that the insulation of the walls of a panel house from the outside is a very popular service. Thermal insulation of concrete panels will allow the apartment to retain heat well in the winter cold, as well as keep the air cool in the summer. So the thermal insulation of panel houses is a universal tool that allows you to increase the degree of comfort in your home. Work can be done on your own, but this is only possible if the apartment is located on the first or second floor of the building. If housing is located higher, it will not be possible to do without the help of specialists. Such services are provided by high-rise builders or industrial climbers.

Insulation of panel walls from the facade

Thermal insulation of the facade surface of the walls of a house built from panels is a much more reasonable measure than internal thermal insulation. And that's why:

Expert opinion

Ask an expert

From the foregoing, we can conclude that it is advisable to insulate the walls of a house from panels from the outside. Insulation from the inside is used only if other options for some reason cannot be implemented.

Varieties of insulation

The following indicators influence the process of choosing a suitable material for wall insulation:


The estimate of materials and the project of the planned work are most often ordered by the house management company or homeowners association. The works on thermal insulation of the facade are carried out by a team of professional climbers.

For use in panel houses, the following types of insulating materials are most often used:

mineral wool

Mineral wool slabs are a very convenient material for outdoor facade insulation work. It is produced under different brands, but the main characteristics of the material from different manufacturers differ insignificantly. The material has a low thermal conductivity, but care must be taken to ensure that the material does not become wet. If this happens, its ability to insulate heat will be significantly reduced. To avoid this problem, a special membrane is laid under the insulating layer, which will be responsible for steam removal.

If a ventilated facade is used to finish the building, moisture vapor will be quickly removed by the air flow penetrating into the gap between the wall itself and the insulation. In this situation, there is no need to lay the membrane layer.

Styrofoam

The material is lightweight, the plates are easily attached to the wall surface. The parameters of heat and noise insulation are at a high level. For outdoor work, only the type of insulator that is not capable of spontaneous combustion can be used. On this type of expanded polystyrene, the G1 marking should be applied, which denotes low-combustible materials. Sadly, not all types of foam on the market are actually non-flammable. Therefore, when purchasing material for insulation, it is necessary to clarify whether the products are certified in accordance with the requirements of GOST.

With external insulation of a panel house, there are restrictions on the thickness of the material for thermal insulation that can be used in work. This indicator is derived by complex calculations that include the average temperature index of the climatic region, and also take into account the type of house - an industrial building, office or residential building.

seams

A significant part of the useful heat inside the panel house can be lost through the interpanel seams. You can solve the problem by processing them. The distance between the ends of the plates is filled with a monolithic mortar, which easily eliminates cracks and cavities in the seams, increasing the efficiency of thermal insulation of the entire structure. Mixtures suitable for processing interpanel joints in concrete houses can be sold both in a form that is completely suitable for use, and for self-preparation of solutions. These compositions may contain expanded polystyrene granules in their structure, capable of retaining heat flow, or air particles to protect against the penetration of cold air from outside.

With a large inter-seam distance, it can be filled with a soft texture insulating fiber. Mineral wool, which has proven itself in external work, can serve as such.

List of its most important qualities:

Fragments of mineral wool fibers are highly volatile and contain formaldehyde components. The combination of these factors does not allow the use of such material for insulating the seams of a panel house everywhere. The best practicality for such work is stone wool. This insulation does not pose a risk to human health and has a stronger fiber structure.

Stages of arranging the insulation of an apartment building from panels

High-quality installation of insulation material is the key to its long service life. Installation quality indicators can depend on many factors. One of the important factors is the type of material to which the insulation will be attached. Most often, special glue for construction or specialized dowel fasteners are used. There are also combined mounting options. The process of warming takes more than one day, because you need to wait for the complete drying of one or another material before proceeding to the next stage of warming.

ADVICE! The best time for arranging wall insulation is the summer months and the beginning of autumn, that is, it is better to complete all work before the onset of the rainy season. The number of people who want to improve the thermal insulation characteristics of their apartments is only multiplying from year to year. It is for these reasons that this important issue is best resolved in advance. In organizations with extensive experience in such work, all days are scheduled ahead for at least a few months.

Insulation laying

The surface to be insulated must be smeared with an adhesive composition, which is applied either with a special spatula with teeth, or laid out with cakes. If you press on it with a plate of insulation, the solution is distributed evenly in the space between the wall and the insulation. Laying rows is carried out in the direction from top to bottom according to the principle of brickwork. Each slab is level with the horizon. Vertical alignment is performed by beacons or by pulling between opposite fragments of a vertical thread.

To increase the reliability of the connection of foam plates with the wall, the insulation is fixed not only to glue, but also to special dowels. 5 fasteners are enough for each insulator plate. The tops of the fasteners should be slightly pressed into the surface of the insulation. When an apartment located on the corner of a building is insulated, the inter-plate joint is also insulated. To exclude the appearance of inconsistencies and the formation of cracks, the rows are alternated in the corner zone.

If gaps nevertheless form between the foam plates, they are closed with scraps of insulating material and fixed with an adhesive solution. Existing corners are closed with a perforated corner, aluminum or metal. Attach it to a solution of glue, alabaster or plaster. The heat-insulated surface remains only to wipe and cover with a layer of plaster. It should be as smooth as possible, since a fiberglass reinforcing mesh will still be laid on top.

Reinforcing mesh installation

On the insulation material it is necessary to apply a layer of glue, 0.5 cm thick. It will absorb the reinforcing mesh while fixing it. The mesh is needed in order to hold the plaster layer, so the installation is carried out with maximum attention and concentration. It is better to fix a large and solid piece of material at once, leaving room for window openings. An adhesive layer is applied on top again. It must be completely dry before you start leveling it.

Finishing

The process of thermal insulation of the panel house wall from the outside is completed by priming and plastering the surface. The primer layer is applied twice, it is convenient to do this with a roller. When the primer is dry, the first thin coat of plaster can be applied. An hour later, it dries up, then it is overwritten, and the surface is given a certain texture using a special textured roller. After that, the main stage of work is considered completed. It remains only to paint the insulated surface in the desired color. The paint is based on acrylic. If the installation technology is performed flawlessly, the external insulation will last at least 10 years.

Thermal insulation of the facade is a laborious and expensive process. But it has a number of undeniable advantages, which are much more important than the time and financial costs. This is the creation of comfort and warmth in your own home.

Finally

All methods of warming are good in their own way. The main thing is to strictly adhere to the recommendations for the use and installation of a particular insulator. If you do not consider yourself a specialist in this field, then for the production of such work it is better to use the services of construction organizations. Such firms have all the necessary licenses, have practical knowledge, and high-level specialists work there. They will be able to quickly and efficiently perform all work with a guarantee.

Video about the insulation of the outer wall of an apartment in a panel house

Living in a panel house is not always comfortable, because in winter the facade can freeze, moisture can accumulate on it, and mold can form. This leads to peeling of the wallpaper and an uncomfortable microclimate in the room - the temperature in the room is below a comfortable level. This is due to the properties of the walls of the panel structure, which are not characterized by resistance to changes in temperature and high humidity. To solve this problem, you will have to insulate the walls, and this must be done from the outside.

Insulation options

Insulation of a panel house from the outside allows you to stop the outflow of heat through the concrete. An additional layer of thermal insulation will protect against the damaging effects of external factors. On the market today you can find many that can be used for insulation inside or out.

Warming inside

For a panel house, insulation from the inside will only make the situation worse. This is due to the movement of the dew point, which will move closer to the inside of the wall. In practice, this means that moisture will accumulate in the walls with even greater force - both the wall and the insulation will get wet, so the life of the facade will be significantly reduced. To avoid such a situation, and at the same time reduce the usable area of ​​​​the apartment and destroy the design, it is worth giving preference to the insulation of a panel house.

Warming outside

The difficulty lies in the fact that the insulation of a panel house with a large number of floors is possible only with the help of climbing equipment. It is clear that it is almost impossible to get money to pay specialists and purchase building materials from public utilities. Moreover, an attempt to insulate the house at the expense of the residents also does not always meet with understanding among all project participants. Therefore, you can take the path of least resistance and insulate a separate apartment.

The main advantages of external insulation:

  • There is no need to violate the interior decoration of the premises;
  • The internal usable area of ​​the apartment is preserved;
  • The supporting structure of the “panel” is strengthened, that is, the building is strengthened, which has a positive effect on the service life;
  • The insulation is an additional sound insulator;
  • The temperature inside the room rises at the same heating costs, since the walls are protected from freezing - heat losses through the panel box are reduced.

How to choose a heater

When choosing a heater for outdoor work, it is worth considering the following factors:

  • The climate of the region in which the panel house is located
  • Wind rose and precipitation
  • Available budget
  • Local features, for example, the design project of the facade of the building.

For the calculation of the estimate and the creation of the project, you must contact the management company or the HOA, while the team of industrial climbers will directly deal with the insulation

Thermal conductivity scheme for building insulation

Types of insulation for panel houses

The following materials can be used for thermal insulation of a panel house:

· mineral wool

It is one of the most popular outdoor heaters. This is due to good performance characteristics, in particular, low thermal conductivity. At the same time, mineral wool is hygroscopic, so it is important to isolate it from moisture. Otherwise, the thermal insulation properties are leveled. For this purpose, it is necessary to lay a vapor-permeable membrane under the insulation layer - it will protect the mineral wool from moisture. It is also possible to equip an air gap in a ventilated facade - in this case, a membrane is not needed.

Extruded polystyrene foam and polystyrene

And extruded polystyrene foam or, as it is also called, penoplex also have low thermal conductivity, so they can be used as heaters for a panel house. Moreover, if you choose from these materials, then most often foam is used as a heat insulator.

This material attracts with its lightness, moreover, such plates are easily attached to the wall. In addition to thermal insulation, they provide additional insulation from sounds from the street. At the same time, when choosing a material, it is important to note the marking - it should be G1 foam, which means “does not support independent combustion. If the foam is flammable, then it cannot be used. It is worth considering that the labeling does not always correspond to the real state of affairs. Therefore, when buying a heat-insulating material, you must request a certificate for the product - it must comply with GOST 30244-94.

External insulation

Carrying out work on the insulation of the facade of a multi-storey building

Insulation of the facade of a panel house is carried out in the following steps:

Preparatory stage

Surface preparation of the facade is necessary - the end walls of the panel house are leveled, the plates are cleaned of plaque. It is also important to seal voids, cracks, and panel joints are sealed. If necessary, it is worth laying a sealant between the joints, while a special mastic is used to seal the cracks. Roughness of the surface of the walls within two centimeters is allowed - such a deviation can not be closed. When all materials are dry, the wall is impregnated with a universal primer, which is applied using a sprayer or roller.

Insulation installation

Since in the vast majority of cases it is foam plastic that is used for thermal insulation of panel houses, it is worth considering the installation technology of this insulation. You can fix the foam by the following methods: put the plates on glue, fix or connect these two options, it is the most reliable choice. The direction of gluing is from bottom to top. In this case, pasting begins with the installation of the starting bar.

After that, we begin to apply glue to the surface of the panel house - the technologies used directly depend on the quality of the walls. If they are even, then you can apply glue with a comb. If, as is often the case, the walls are uneven, then the glue simply pounces onto the surface. It is important to carefully fill the seams with glue. All this allows you to get rid of voids under the heat insulator. It is not necessary to apply glue to the foam.

Installation of foam on the wall

The option when the glue is applied to the foam, and not to the house, is not suitable in this case, since the voids under the insulation will become natural cold bridges, which will reduce the effectiveness of the entire event as a whole.

Styrofoam is applied to the glue layer and pressed well. After gluing all the plates, you need to leave them alone for a few days. During this period, the adhesive solution will dry and shrink, after which it will be possible to perform the next stage of work. As for fixing the plates with dowels, you can choose plastic fungi. This is due to the lightness and low strength of the foam - such fasteners will save the facade from unnecessary heat loss.

It is worth paying attention to the gaps - they must be filled with mounting foam, cutting off the excess after the material hardens.

As for the dowel caps, they must be covered with an adhesive mixture. All the irregularities remaining after the glue has dried can be removed with ordinary sandpaper.

Reinforcement preparation

The fragility of the foam is a serious drawback, so the insulation needs to be reinforced - it is enough to glue a thin mesh. Such protection should prevent the destruction of the foam due to atmospheric phenomena and other adverse factors.

Preparation for reinforcement is as follows: first, the corners are pasted over, after which you can proceed to pasting the walls themselves. To simplify the process, grids with ready-made corners are used, which minimizes time. If there are no such grids, then you will have to make corners from a regular grid. It is enough to cut off a long strip 30 centimeters wide and bend it at an angle - this design is pressed against the corner of the house smeared with glue. In general, cutting the mesh into fragments greatly simplifies the installation itself, which makes it possible to successively cover the areas smeared with glue with fragments. At the same time, the mesh should overlap at the junction.

Wall insulation in a panel house will make your life comfortable and enjoyable. The highly professional specialists offered today, coupled with modern technologies, do an excellent job with the wall insulation procedure, which reduces heat losses, guarantees optimal temperature and humidity levels.

There are two ways to normalize the microclimate of the room:

  • internal;
  • outdoor.

Preference for one or another option is justified by the type of building, number of storeys, and total area of ​​the premises.

There are many reasons why the walls of panel houses freeze through, among them:

  • poor heating in winter;
  • lack of normal ventilation;
  • unscrupulous approach to the work of builders when building a house (poor sealing of gaps between panels, window openings);
  • a large accumulation of moisture in the wall structure;
  • poor or worn-out waterproofing.

Most residents are inclined to think that it is necessary to insulate the walls in a panel house from the inside, and they are not always right.

Why you shouldn't insulate walls from the inside of your home

Note that the insulation of walls from the inside of a panel house is associated with disadvantages and is fraught with problems, namely:


It would be more correct to consider the method of thermal insulation of the wall in the panel house from the outside. The advantages of this method are the following factors:


External insulation is important to accompany the protection of the insulation from external factors, for which ventilated facades are mounted on the facade surface or the insulation is finished in a wet type.

There are two priority methods for external insulation of panel wall structures:

  • dry;
  • wet.

Thermal insulation by the dry method involves the installation of a special protective screen on the surface - a “ventilated facade”, based on a metal frame, insulation is fixed on it, external cladding is the next step.

Insulation by the wet method is a frameless installation of insulation directly on the problem area, followed by finishing with building mixtures. As a rule, they mean various types of plaster, which differ in relief, colors, efficiency and other qualities.

The sequence of work consists in the following operations:

  • repair of interpanel seams (cleaning of old plaster, sealants);
  • priming and drying;
  • installation of a new sealant in the seams, then - secondary primer and putty;
  • preparation of walls (thorough cleaning of the old coating and dirt).

The use of polystyrene is resorted to in the wet method, in the form of a finishing coating to protect the insulation, building mixtures that are resistant to temperature extremes and precipitation are usually used.

Basalt wool is more applicable when using frame technology for surface insulation outside the house, it is placed in the cells of the metal structure of the ventilated facade and sealed with a vapor barrier membrane. The outer skin of the frame can be made of plastic panels, profiled sheet, wood and other materials.

With large areas of the room, it is realistic to consider the existing methods of wall insulation and finish both outside and inside.

Video how to conduct insulation in a panel house from the inside

As a material for wall insulation from the inside are offered:

  • mineral wool;
  • expanded polystyrene;
  • polyurethane foam;
  • glass wool;
  • cork insulation;
  • penofol;
  • Styrofoam;
  • fibrolite;
  • foamed polyurethane.

Many, especially if the walls of a panel house are insulated from the inside on their own, are interested in the possibility of using special fasteners for this. In this capacity, fasteners are offered on the construction market - " fungi”, which are securely attached to the surface, for example, extruded polystyrene foam.

Clearly, how to insulate a wall in a panel house from the inside is shown in the following video:

How to insulate a wall in a panel house, it is interesting to learn from the video:

Note that the insulation for thermal insulation of internal wall structures should be characterized by the following characteristics:

  • long service life;
  • high level of TB and increased resistance to ignition;
  • low level of heat loss;
  • preservation of the original form;
  • environmental Safety;
  • resistance to rodents.

The insulation must, upon sale, have the necessary certificates for compliance with all fire and sanitary safety standards required for execution.

When choosing how to finish from the inside, there is always an acute question to preserve the dimensions of the room as much as possible. Therefore, it is better to refuse to use drywall for these purposes and pay attention to the most reliable and narrow material that performs its functions qualitatively, preserves the dimensions of the room and does not harm people's health.

Insulation for wallpaper, two priority groups:

  • rolled up;
  • plaster with high thermal insulation properties.

This issue is well covered in the following video:

conclusions

Each of the ways to insulate walls in a panel house from the outside and from the inside is good enough if you follow the recommendations regarding the use of a particular material.

In addition, if you are not a specialist, it is better to turn to specialized companies that have licenses, sufficient practical experience and highly professional specialists for this type of work. It is they who are able to carry out the entire sequence of technological operations promptly and efficiently, in addition, warranty obligations upon completion of work will not be superfluous, and will prove to be a guarantee of quality and reliability.
