Quite a few owners of apartments located in a panel house have to deal with the fact that living in such real estate is simply impossible and very difficult, due to the fact that there is always severe cold in the premises. winter time. This is due to the fact that the walls panel house are usually very poorly insulated, as a result of which draft and cold penetrate through them, as well as through windows and other surfaces in the apartment, and it is not possible to cope with them even with the help of high-quality and reliable heating turned on at full power. As a result, living in such an apartment will not be very comfortable, pleasant, or safe, since you can easily catch a cold. That is why, in order to increase the comfort of living, every owner of an apartment in a panel house must take care of the full and effective insulation of your apartment, which should be not only internal, but also external. Only in this case can you achieve the best and optimal result of all planned work. Also, if there is no opportunity or money to carry out insulation both outside and inside, then in this case the most optimal solution would be to carry out work related to external insulation, since it is considered the most effective.
Features of insulation of a panel house
Initially, you should determine what material will be used for these purposes. It must meet certain requirements, which include safety for people, as well as high thermal insulation parameters, since in this case the insulation will really act the right decision for complete and comprehensive insulation. Most often, popular and affordable mineral wool is used for these purposes, and it is also possible to use foam plastic, which meets all the requirements and is also a material that is very simple and easy to work with.
How to insulate the walls of a panel house from the outside?
This work can be completed completely different methods with specific differences. To do this, you can make a curtain façade, which is considered the most optimal solution. In this case, a special frame of slats or profiles is formed along the entire perimeter of the wall, and slab heat-insulating materials are laid in its cavity, which should be mounted with a small joint. Next, the resulting structure is sheathed with any suitable decorative materials, which will not stand out too much from the background general finishing Houses. With this design you can get a truly ideal work result, but it will require quite an investment. large quantity money, as well as the work itself has certain difficulties. Therefore, it is often simply impossible to cope with all the work with your own hands, especially if the apartment is located on a fairly high altitude, as a result of which you will have to constantly use special equipment for work.
The walls of a panel house can be insulated not only from the outside, but also from the inside, but it is advisable to carry out this work only in conjunction with external insulation. Also interior work are the only solution if it is simply impossible to implement them from the outside. Insulation inside the house is a fairly simple job, since for this purpose a frame of profiles is created along the entire perimeter of the walls, into which insulation is laid, and after that it is sheathed with sheets of plasterboard, onto which any suitable materials are applied at the last stage of work Decoration Materials. Such work is considered quick and simple, but as a result it will be necessary to reduce the area of the premises, and the insulation will not be the most effective.
Over time, the walls of a panel house require 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.
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 the exterior decoration of the house will look new. In addition, insulating walls from the outside has the following advantages:
External wall insulation is most effective for panel houses - it can save up to 50% of heat.
The choice of which material is best to insulate the walls from the outside is influenced by:
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:
For outdoor work, it is convenient to work with mineral wool slabs, which are produced by various manufacturers. It has good performance in basic characteristics, including thermal conductivity. However, you need to ensure that the mineral wool does not get wet, otherwise it will lose its 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. 
It is distinguished by its lightness and simplicity when laying slabs on the wall. Also has good parameters for heat and sound insulation. For outdoor work, it is important to use a material that does not support independent 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 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).
Depending on the chosen insulation method, installation will vary. There are two main technologies:
The process of insulation using the “wet” method is described below.
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 plaques, seal voids and cracks, especially paying attention to panel joints. 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.
Attaching thermal insulation material to walls is possible in three options:
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 the cracks from the fasteners are filled with special polyurethane foam, intended 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.
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 a special adhesive solution for facade work is evenly applied to the insulated surfaces, and the mesh is pressed into it. Then another adhesive layer is applied for leveling. After installing the mesh over the entire house, wait for the glue to dry before treating the surfaces sandpaper from mortar leaks and unevenness during the fastening process.
The reinforcement provides mechanical stability for the final decorative covering panel house.
After insulation, external facades are usually decorated with decorative plaster. For the best adhesion of materials, the general layer of thermal insulation is primed again.
In addition, the technology of suspended ventilated facades is often used for residential apartment buildings. The thermal insulation layer has already been completed - all that remains is to install the outer cladding with a ventilation gap.
Today we offer a wide selection of materials for exterior finishing in the curtain façade system:
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.
Increasingly, “spots” appear on multi-storey buildings in the form of bright multi-colored squares around the windows. This indicates that the apartment owners took care of the insulation of their housing. Residents of panel houses often resort to this service. What is panel insulation? apartment building, and what does it give?
In winter, everyone's desire is to return to a warm, cozy apartment and relax after a hard day. But expectations do not always coincide with reality. Due to rain, winds, high humidity, and temperature changes, the walls of houses freeze. The façade of the building is gradually collapsing and cracks are appearing. On inside load-bearing structures, due to lack of heat, mold appears and air humidity increases. Insulating concrete walls solves this problem.
A layer of insulation helps to avoid destruction of the façade part of the wall and retain heat within the apartment. In addition, there are a number of advantages when insulating the external walls of a panel house:
The price depends on the area of insulation and the quality of the materials used. But when the issue of heat is at stake in winter period, then the situation speaks for itself.
The quality and durability of the insulation depends on the selected material. Mineral wool and polystyrene foam are popular.

The amount of material used is calculated based on the area of the wall that needs to be insulated. Plus 15% of the total quantity in reserve. Before attaching the insulation to a panel house, the walls go through a preparation stage.
In order for the insulation to fit tightly to the wall, the surface must be leveled and the cracks sealed.
Important! All stages are carried out only by specialists. You need to thoroughly know the sequence of work and its features.
The foundation preparation process goes through several stages:
Along with preparing the walls, the window slopes are put in order. To avoid the formation of fungus, the surface is primed. For this, a sprayer is used, or less often a special roller.
Interesting! This type of work is carried out mainly at heights. This is a dangerous activity, and most often, 2-3 people are involved in installation. But there are also loners who have gotten used to performing all the stages on their own.
High-quality installation is the basis for the durability of insulation. It depends on many factors. One of them is the material on which it is attached. Typically, construction adhesive, dowels, or a combination of both are used. The entire process takes several days to allow the materials to dry as they are used.
Recommendation! Insulation is carried out in summer and early autumn, before the rainy season begins. Every year more and more people want to keep their rooms warm. Therefore, it is worth addressing this issue in advance. After all, the entry in the best companies wall insulation begins literally six months in advance, or even earlier.
The glue is applied to the surface either in lumps or with a notched trowel. Thus, when pressed, the glue evenly fills the space between the insulation and the wall. The rows are laid out in a checkerboard pattern from bottom to top. The slab is applied to the surface from the bottom to the top corner, and is leveled to the building level. Also for a level, use beacon corners or stretch a vertical thread between opposite sheets.
Modern technologies present two options for insulating the surfaces of the walls of an apartment building: from the inside and from the outside. Both options will solve the problem of low room temperatures and rapid heat loss. More was installed in panel houses cast iron radiators with excellent heating qualities, but due to the thinness of the walls and their direct contact with frosty air, the efficiency of the radiators is significantly reduced.
Both options are suitable for this, but their implementation is radically different, so it is necessary to determine a simpler and more economical one that you can do yourself.
Insulation of the facade of a panel house is carried out in the following stages:
Preparation of the façade surface is necessary - leveled end walls panel house, slabs are cleaned of plaque
It is also important to seal voids and cracks; panel joints are sealed. If necessary, it is worth laying a sealant between the joints, while special mastic is used to seal cracks
Unevenness of the surface of the walls within two centimeters is allowed - such a deviation does not need to be repaired. When all the materials are dry, the wall is impregnated with a universal primer, which is applied using a sprayer or roller.
Since in the vast majority of cases foam plastic is used for thermal insulation of panel houses, it is worth considering the technology for installing this insulation. You can fix the foam using the following methods: placing the slabs on glue, fastening them with dowels, or combining these two options, which is the most reliable choice. The direction of pasting is from bottom to top. In this case, pasting begins with the installation of the starting strip.
After this, 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 smooth, then you can apply glue with a comb. If, as often happens, the walls are uneven, then the glue is simply thrown 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
There is no need to apply glue to the foam.
The option when the glue is applied to the polystyrene foam, and not to the house, in in this case is not suitable, since the voids under the insulation will become natural bridges of cold, which will reduce the effectiveness of the entire event as a whole.
We apply the foam to the glue layer and press it well. After gluing all the plates, you need to leave them alone for several days. During this period, the adhesive solution will dry and shrink, after which the next stage of work can be performed. As for fastening the slabs with dowels, you can choose plastic mushrooms. This is due to the lightness and low strength of foam plastic - such fasteners will save the facade from unnecessary heat loss.
As for the dowel caps, they must be covered with an adhesive mixture. All irregularities remaining after the glue has dried can be removed with regular sandpaper.
The fragility of polystyrene foam is a serious drawback, so the insulation needs reinforcement - just glue a thin mesh. Such protection should prevent the destruction of the foam due to atmospheric phenomena and other unfavorable factors.
Preparation for reinforcement proceeds as follows: first, the corners are pasted over, after which you can proceed to pasting the walls themselves. To simplify the process, meshes with ready-made corners are used, which minimizes time consumption. If there are no such meshes, then you will have to make corners from a regular mesh. It is enough to cut a long strip 30 centimeters wide and bend it at an angle - this design is pressed against the corner of the house greased with glue. In general, cutting the mesh into fragments greatly simplifies the installation itself, which allows you to sequentially cover the areas coated with glue with fragments. In this case, the mesh should overlap at the junction.
After gluing the mesh, you need to wait for the glue to dry, after which you can use a plastic float to clean off the excess solution and remove any unevenness.
Before finishing A leveling layer is applied to the entire treated façade. After this, it is necessary to apply a primer and a layer of plaster. The final stage is painting the wall, preferably in a color that will not stand out too much against the background of the main color of the multi-story panel building.
Modern construction market offers frighteningly big choice thermal insulation materials. The “ordinary” man in the street, not familiar with the specifics of the work, is dizzy from such diversity. Unscrupulous sellers take advantage of this, instilling the idea “the more expensive, the better.” Today we will not consider all the options for insulating the external walls of a house, but we will talk about the most inexpensive, high-quality materials that have been proven over the years.
Among the most popular insulation materials special place occupies polystyrene foam. This inexpensive material, properly performing its assigned function. It is perfect for external insulation, as it provides 100% thermal insulation regardless of air humidity and temperature changes.
This material is non-toxic and fireproof, but a reservation should be made here. The foam itself does not burn, but melts and at the same time emits black acrid smoke, which is hazardous to health. But if you follow safety measures, it will last a long time and faithfully. The words about non-toxicity and harmlessness to health are confirmed by the fact that even children's products and food products are packaged in polystyrene foam.
Polyfoam is not susceptible to mold, fungi and insects. It does not deteriorate, does not swell or shrink, maintaining its original shape. The service life of the material ranges from 20 to 50 years, depending on the quality.
External insulation of the walls of the house with polystyrene foam allows not only to protect interior space from the vagaries of the weather, but also transforms the outside of the house. The material creates a very convenient surface for finishing, ranging from relief plaster to siding or slabs.
Working with polystyrene foam is quick and easy; all you need is basic skills and equipment.
Stages of insulating the external walls of a house with polystyrene foam:
Today you can often hear advertisements for high-quality and reliable penoplex insulation, which is why many people believe that this is the name of the material. In fact, the material is called extruded polystyrene foam, and it is produced under the Penoplex brand.
Extruded polystyrene foam is used for internal and external insulation of houses of any type. Today it is one of the most popular materials, and this is explained by its excellent performance characteristics.
Advantages of penoplex:
Unfortunately, ideal building materials do not yet exist, so even with such a large list of advantages, penoplex also has disadvantages. The most obvious is poor adhesion. Since the material is very dense, it does not absorb adhesives well, so it is difficult to glue it to vertical surface. To do this, additional fixation is performed with dowels, but most builders recommend using penoplex for internal insulation.
External insulation of house walls with penoplex is best done in the region ground floor, since even additional fixation of the material will not protect it from damage. In other words, it very quickly begins to fall off and spoils the appearance of the building. In the area of the plinths, you can make a ventilation space or use an outer layer of waterproofing to prevent the adhesive layer from getting wet and breaking down.
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 the heating season has not yet begun, uncomfortable conditions are created inside such an apartment. Dampness appears in the corners, 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 most susceptible to low temperatures. In winter, even if available central heating, the situation is only getting worse.
The walls can freeze completely, especially in the corners, the interior decoration will begin to fall off, and 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 diseases caused by high humidity air.
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 that you need to try to insulate the walls. How can I do that? How to carry out internal insulation? 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 insulation materials exist.
The choice of which material is best to insulate the walls from the outside is influenced by:
The estimate and project for the work are usually drawn up by the management company or the 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:
For outdoor work, it is convenient to work with mineral wool slabs, which are produced by various manufacturers. It has good performance in basic characteristics, including thermal conductivity. However, you need to ensure that the mineral wool does not get wet, otherwise it will lose its 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 due to the air gap and the membrane does not need to be used. 
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.
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).
Insulating a panel house from the outside allows you to stop the flow of heat through the concrete. An additional layer of thermal insulation will protect against destructive effects external factors. On the market today you can find many materials that can be used for insulation inside or outside.
For a panel house, insulating it 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 service life of the facade will be significantly reduced. To avoid such a situation, and at the same time reducing the usable area of the apartment and destroying the design, you should give preference to insulating a panel house from the outside.
The difficulty is that insulating a panel house with a large number of floors is only possible with the help of climbing equipment. It is clear that it is almost impossible to get money to pay specialists and buy building materials from utility services. Moreover, an attempt to insulate a house at the expense of the residents also does not always meet with understanding from all project participants. Therefore, you can take the path of least resistance and insulate a separate apartment.
The main advantages of external insulation:
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:
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 no additional work on the insulation is 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.
Foam adhesive is best suited for gluing foam boards.
Insulation in the apartment concrete walls They are attached from the inside under false walls made of plasterboard. If you took the path of least resistance and chose stone wool or, in extreme cases, foam plastic as thermal insulation, then no difficulties should arise in your work. How to insulate a corner apartment in a panel house:
After it has been puttied, you can glue any finish onto the drywall: tiles, wallpaper, decorative stones, papier-mâché or just paint. There are situations when it blows strongly from the corners. In this case, the question arises: how to insulate corners in a panel house? Alternatively, you can simply blow them out with foam from the inside or cover the joints of the plates with sealant. This should help, but if capital measures are needed, then it is necessary to insulate the interpanel seams from the outside. There is a technique called " Warm seam" It involves cleaning the seam from all contents, filling it with special polyurethane foam, laying Vilaterm and sealing the seam with mastic.
Today's market for thermal insulation materials is huge, but there are products that are deservedly considered classics thermal insulation of a panel house from the outside
.
Among these materials are:
Let's look at each option separately to understand what advantages this or that type of insulation has.
Mineral or stone wool
usually called insulation based on extruded stone chips. The point of using stone is that it creates a foam slab with stable walls. Inner space such slabs
90% filled with air. And today air is the material with the lowest thermal conductivity. Therefore, all insulation materials include air.
There are three types of mineral wool:
Sandwich panels are used primarily due to the possibility of quick installation. The panel itself is insulation sandwiched between two layers construction material. The following acts as insulation:
Styrofoam
- this is the most popular material in Russia for insulating building facades. The undoubted advantage of this insulation is that it is absolutely not susceptible to moisture, when the basalt mineral wool slab turns into rags over time. As a rule, the service life of such insulation does not exceed 10 years. Foam manufacturers guarantee from 30 to 50 years of service.
Attached to the façade is polystyrene foam using dowels
or with special glue. And most often, both methods are combined to create a reliable fastening.
Insulation work will require proper skill and attention, but it can be done easily if you strictly follow the technology and have it on hand necessary tool. Here is a list of what you may need:
The specified list may be wider depending on the installation method, but you can easily get by with what is listed. Having everything you need, you can get to work. Remember that it is better to ventilate the room well, and carry out noisy work only at the permitted time of day in order to avoid conflicts with neighbors.
According to their own technical specifications Work on installing a heat-saving coating in a panel house from the inside is carried out from the following common materials:
When installing a light insulating wall cladding without lining the top with strong sheets of insulation board (foam plastic, polystyrene foam, stone basalt wool) simply hide with a layer of plaster:
An important criterion for selection is the non-flammability of the material and environmental safety, since it is installed indoors.
You can compare the indicators that this or that thermal insulation has using the table:
It is one of the popular options for insulation because it has a number of undeniable advantages:
Available in the form of rolls, stitched mats and slabs. Of all types of this material, stone basalt wool is preferable.
Foiled polyethylene foam is used for reflection infrared radiation and creating a barrier to water vapor. To surfaces hidden under the finishing cladding of sheet coverings, heat rays practically do not penetrate, so there is little point in installing reflective insulation in the walls.
Can be used as protection of mineral wool from a wet wall, additional sound insulation, vibration damping.
Natural cork is used for high-quality internal insulation of small thickness on panel walls. This is the most environmentally friendly heat insulator. Performance characteristics include high strength, low thermal conductivity, low weight, durability, and elasticity. For more information about which insulation is better, watch this video:
The technology for insulating the walls of a panel house from the inside with smooth, rigid slabs of foamed polymer includes careful preparation of the surface for installation. Unresolved wall deflections will create voids in which condensation will accumulate.
The slabs are laid out staggered on a layer of glue; the use of anchor umbrellas in this case is not recommended (through passages for cold). Each joint is sealed with sealant. Another method of fastening is to lay between T-profile, fixed to the ceiling and floor.
The thickness of the material will depend on the climate zone. The following initial data can be used in the calculation:
Applying a layer of polyurethane foam requires special equipment and installation of a frame. The work is carried out by specialists with practical experience. The strength of the hardened foam is low and it is covered with a protective cladding (gypsum plasterboard, plywood). For more details, watch this video:
Liquid types of insulation include the achievement modern science - special paints. They are expensive and require careful adherence to application technology (thickness and sequence of layers, direction of brush movement). In case of violation of instructions thermal resistance of such coverage is sharply reduced.
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.
By performing steps step by step, you can achieve an ideal result. Begin:
Glue (liquid nails) is generously applied to the surface of the wall and penoplex panels, and then pressed tightly against each other. We carry out such actions with each panel, placing the next one exactly in the groove with the previous end side. This applies to both the side sections and those on top. Penoplex is easily cut with a knife, so where a whole panel does not fit, it is carefully cut and inserted into the space
It is important to cut exactly to size in order to leave a minimum of gaps and lay them exactly at the end.
The panels can also be fastened using wall anchors and plastic mushrooms; for this, holes are made in the walls and fasteners are driven into them directly through the attached polystyrene foam. This method is very noisy, so we recommend the first option.
All joints between panels, walls, floors and ceilings are coated with sealant
This is necessary to ensure maximum thermal insulation.
The tighter the foam is pressed against the wall surface, the better its insulating properties, so don’t skimp on glue or anchors.
This installation option involves final finishing using plaster. After the sealant has dried, the entire surface of the wall is covered with putty and leveled. If you want to further strengthen the layer, you can smear a special mesh (serpyanka) into the plaster.
After final leveling, the putty must be allowed to dry and then primed, thereby preparing its surface for painting or wallpapering.
Installation is not at all difficult. The main thing is to stick to technology, then the work will go quickly and efficiently. After finishing, you will immediately feel that the apartment has become much warmer and drier, even if it is an end apartment. That's because isolation helped get rid of contact warm air with the surface of cold walls. Therefore, if heating occurs not with radiators, but with heated floors, they can be turned on less often, thereby saving on utility costs.
“Warm seam” technique for sealing interpanel joints.
Last time we dealt with this in various ways. Today we will tell you everything about insulating a panel house from the outside: what materials are used, what glue is best to attach them to, what methods are available. It has been repeatedly noticed that a lot of companies do outright hack work, the results of which are deplorable. Either the thermal insulation does not work or disappears altogether, especially on the upper floors, where gusts of wind are quite significant. Sometimes, even if everything is done according to technology, the result is simply scary to look at - everything is crooked, ugly, not like people’s. Therefore, you have to control everything, delve into the nuances, ask questions. Yes, this irritates the workers, but that is their problem. The main thing is a high-quality result - without compromise.
