People living in panel houses often experience moisture accumulation in the walls and facade freezing in winter, mold formation, peeling wallpaper and others. unpleasant phenomena, not to mention reducing heat levels in living spaces.
And this is not surprising, because unlike brick buildings, panel houses are less resistant to high humidity and temperature changes. Wall insulation helps to cope with this problem. panel house, made outside. Why should it be done outside? Let's try to figure it out.
Inside or outside?
Insulation is designed to prevent heat leakage through the walls, and at the same time protect the facade from premature destruction. Modern market offers many various materials, intended for outdoor and internal insulation. Since only professionals can insulate the façade of a panel house from the outside, residents may want to insulate the room from the inside. However, it is better not to do this.
In this case, the dew point will move inward, which will lead to even greater accumulation of moisture in the walls. As a result, not only they, but also the insulation will get wet, which will significantly shorten the life of the facade. Therefore, it is more advisable to insulate walls from the outside. It won't cut it usable area apartment and will not disturb the interior decorative finishing.
At the same time, it is not so easy to insulate multi-storey building outside. Only industrial climbers can do this. And it is very difficult to force utility companies to pay for their work and the purchase of building materials. And not all residents of the house agree to chip in and hire construction team. Fortunately, today it is quite possible to carry out external insulation of a separate apartment.
If you do not have construction and climbing skills, do not try it yourself! However, if you live on the first floor of a panel house, then you can do it yourself, using a ladder.
Types of insulation
To insulate the walls of a house from the outside, the most different materials, however, the most popular over the years include:
- stone or glass wool;
- Styrofoam;
- extruded polystyrene foam.
The main property that these insulation materials have in common is low thermal conductivity. Most often as heat-insulating material foam is used.
Insulation installation technology
Preparing the walls
Immediately before insulating the walls, the working surface is prepared. All irregularities are smoothed out and sealed with primer. Special attention require seams and façade finishing.
Any peeling paint should be sanded off, as should any peeling trim. To check its quality, just run your hand along the wall. If your palm remains clean, then no primer is needed. If there are any problems, it is better to be safe.
Installation of insulation
Polystyrene foam is often used to insulate a panel house, so let’s consider the technology of its fastening.
If you live on the ground floor and decide to do the insulation yourself, then for the job you will need a large and small spatula to apply glue to the wall.
It should be noted that there are three methods of attaching it: with glue, with dowels, or both. It is most effective to use glue and dowels together.
The walls are covered from bottom to top. A starting strip is nailed to the bottom of the façade. If the walls are uneven, then glue can be “thrown” on smooth surfaces it can be applied with a comb.
Fill the seams carefully. There is no point in applying glue to the insulation sheet. To ensure that there are no depressions left under the foam, fill all the depressions and uneven walls with adhesive solution. Otherwise, the voids will create additional “cold bridges” through which heat will escape from the apartment.
When the surface is treated with glue, you can apply a sheet of foam plastic and press it well against the wall. Before the next stage of work, it is better to wait a few days so that the adhesive solution is completely dry and the insulation shrinks, and then continue work.
To fasten the insulation, dowels are used - fasteners consisting of a circle, a plastic sleeve and a galvanized nail, which is driven into the sleeve. Since foam plastic is lightweight, you can also use plastic nails. They will protect the facade from unnecessary heat loss.
To reliably insulate the building, holes are drilled around the perimeter and in the center of the foam glued to the wall. The depth of the hole must exceed the length of the dowel by two centimeters, otherwise the fastening element will stick out. To ensure reliable insulation, the foam sheets must fit tightly to the wall and to each other.
Keep an eye on the gaps. In some cases it is useful to fill them out polyurethane foam, the excess of which is cut off after drying, and the seams are rubbed and adjusted. At the final stage, the dowel heads and seams are puttied with an adhesive mixture. Minor defects The marks that appear after the mixture has dried are removed using sandpaper and a plastic grater.
Pasting walls with mesh
Since polystyrene foam is a fragile material, it requires reinforcement, which is done by gluing a thin mesh. For installation outside the building, a special mesh is used that can withstand all atmospheric phenomena and maintain their properties under the influence of adverse external factors.
At the first stage, the corners are covered with mesh, and only then – the main surface of the walls finished with insulation. Special meshes with corners will help make the task easier - they will help you insulate your house without additional hassle. Otherwise, long strips thirty centimeters wide are cut from the mesh and bent at an angle. Then, using a spatula, the corner of the house is covered on all sides with glue, on top of which a mesh is placed and smoothed away from the corner.
To make work easier, the mesh can be cut into pieces, meter by meter, and then attached in small areas. The mesh is glued with an overlap. After the glue has completely dried, the walls are treated with plastic floats, excess dried mortar and unevenness are cleaned up. After making sure that the mixture has completely dried, a leveling layer is applied to the walls of the panel house and the final finishing begins.
That's all you need to know about finishing a panel house. Installing insulation outside can reliably protect apartments from the cold. Today many construction companies offer insulation services multi-storey buildings. But if you live on the ground floor and have the necessary skills and tools, then you can try to do the insulation yourself.
Panel houses were considered chic during Khrushchev's construction. Insulation of the facade of a panel house - quick and cheap technology allowed to put into operation great amount square meters, with which residents still suffer. In roofless buildings with thin walls sometimes too wet and cold. The inner surfaces of the walls are infected with fungus, and mold can even grow in the bathroom.
Figure 1. External insulation of the entire house.
The best option for all residents may be insulation of the facade of a panel house. It is not only Khrushchev houses that suffer from such “diseases”. The technology of panel housing construction is still popular and far from perfect. Therefore, the method should be adopted by all residents of “panelkas”.
I love it building structure can be insulated from the outside and inside. In any case, we will get a cake that will consist of structural material and insulation. Insulation is a material with low thermal conductivity, the main task of which is to prevent loss heat from the apartment.
If you insulate a house from the inside, then there is a high probability of condensation occurring on the inner layer of the wall behind the insulation. This is due to the fact that the air flow gradually heats up to temperature inside the building, passing layer by layer pie from the enclosing structure. At some point, the temperature of the air flow reaches the dew point and condensation occurs. This is useful for the indoor climate, since less heat will be spent heating dry air, but for structural materials such a shower poses huge problems.
If insulation is carried out from the outside, the dew point will shift into the thickness of the insulation, which ideally should not be harmed. Advantages of external insulation:
- Dew point offset.
- Protection of the enclosing structure from getting wet.
- Does not occupy the interior space of the apartment.
- Does not require high-quality and expensive vapor barrier.
Any heating engineer, if possible, will choose external insulation, this is confirmed building codes and rules. The use of internal insulation is always an extreme measure or unprofessionalism.
Materials for insulating the walls of panel houses outside
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:
- mineral wool;
- sandwich panels;
- Styrofoam.
Figure 2. Expanded polystyrene for facade insulation. Let's look at each option separately to understand what advantages this or that type of insulation has.
Mineral wool
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 in total mineral wool:
- Basalt mineral wool with a synthetic binder. This is the most popular option. If you hear someone talking about mineral wool, then most likely they mean this type of insulation. Mats made from this material are loved by all heating engineers for their ease of installation, low cost and good thermal insulation properties. However, for insulation façade houses basalt wool is used extremely rarely, since its installation requires a frame, which must be thermally insulated separately to prevent cold bridges from appearing.
- Glass wool. It was used everywhere for insulation in the last century. Now it is completely unsuitable as insulation: it constantly crumbles, falls off quickly and is extremely dangerous to install. When installing basalt mineral wool slabs It is enough to use a respirator. To install glass wool blocks, you will have to protect your entire body. Besides thermal insulation characteristics the material is very mediocre.
- Mineral wool based on cellulose. The name speaks for itself. This is a fire hazardous insulation made from foamed paper residues. The main advantage that manufacturers are trying to cling to is environmental friendliness. But the insulation does its job poorly, and therefore there is no particular point in using it.
Sandwich panels
Sandwich panels are used primarily due to the possibility quick installation. The panel itself is insulation sandwiched between two layers of structural material. The following acts as insulation:
- Foamed polyurethane. High quality but expensive material. It is not profitable to use it to insulate the facade of an apartment panel building. But a sandwich panel with such insulation is perfect for a private home.
- Mineral wool. This insulation has already been mentioned earlier; all its properties are transferred here completely. The use of sandwich panels protects the mineral wool board from precipitation, making installation easier.
- Styrofoam. These are the most popular sandwich panels. The insulation used makes them lightweight and quite effective.
Styrofoam
Styrofoam 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.
Figure 3. Insulating the facade with polystyrene foam. 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.
Methods of external insulation of facades
In total there are two installation method insulation on the building facade:
- Dry method or ventilated facade.
- Wet method.
Each technology has its own advantages, so we will consider each option separately.
Insulation of facades ventilated facade
The dry method does not involve the use of mixtures with added water. In order to create thermal insulation layer using this method, a thermal shield is made from insulation materials, which are covered with panel materials. The materials we have already discussed are used as insulation materials. The façade is called ventilated because a small amount of space is left between the panel material and the insulation. air gap for ventilation of insulation.
Facade insulation wet facade
This method involves insulation façade surfaces using specialized mixtures water based. These mixtures can have different compositions. IN Lately Cellulose-based foam insulation is increasingly being used. The main advantage of this method: filling all cracks and holes. Wet method does not leave cold bridges through which heat can flow out of the room.
Insulation technology
Regardless of the used insulation installation technologies, procedure wall preparation required. All materials are purchased before installation. Purchasing additional consumables during the process is a poor calculation of materials, which can lead to poor-quality installation of insulation.
Preparation of materials
As a rule, workers have an outline plan of the building. This means the required quantity material you can always calculate. This is the area of the walls minus the area of the windows. The resulting insulation area needs to be increased by 20 percent. Based on the consumption per insulation area, fasteners are calculated and the required tools are pretended to be. Approximate consumption of fasteners per sq.m. insulation is contained on the manufacturers' websites.
All foam sheets or mineral wool slabs must be unpacked on the ground, laid out and molded. As a rule, any insulation can be easily cut with a saw or a special knife.
Required materials and tools
In addition to the insulation, you will have to purchase a sealant for seam sealing. For different insulation materials different consumables are required. In the case of using polystyrene foam, in addition to the sealant you need to buy reinforcing mesh, plaster, glue and dowels.
For mineral wool you will need self-tapping screws and iron slats. Self-tapping screws and glue are needed for installing sandwich panels.
Here is a sample list of tools for surface insulation building:
- scaffolding for work at heights;
- a set of spatulas for sealing joints, preparing walls and applying glue;
- drill;
- insurance.
After all the tools are ready and the materials are molded, you can begin installing the insulation.
Preparing the walls
First of all, the old coating is removed: plaster and cracked paint are cleaned from the surface panel walls Houses. It is imperative to coat all joints with putty and seal all cracks in the panels with plaster or mortar. Installation of insulation is carried out only in the most clean, flat wall. If the wall is sloping, this must be taken into account during installation. We’ll tell you exactly how a little later.
Figure 4. Insulation of the facade of a multi-storey building. Once the walls are prepared, you can begin installing the insulation. We will describe in detail only the installation of foam plastic, as the most popular and effective material.
Installation of insulation
On the wall glue is applied one by one, from bottom to top, foam plates are attached.
Important! If the wall is uneven, then you can use glue to level it, but no more than 2 cm. For large distortions, you will have to come up with a more expensive method.
After all the plates are glued, you need to additionally attach the foam with dowels. To do this, a hole is drilled through the slab, the length of which should reach the wall. After this, the expansion umbrella is inserted and the dowel is driven in. The umbrella should be on the same surface as the rest of the insulation plane; to do this, it needs to be recessed a little. This is necessary for subsequent reinforcement. Nothing complicated about installation of foam plastic no, it's fast enough and reliable way provide thermal protection for the building.
Insulation of interpanel seams
When preparing the walls, it is necessary to sealing interpanel seams. To do this you need:
- Open the joint.
- Clean the seam from old putty, sealant and dirt.
- The next step is to prepare the substrate for new insulation. To do this, the seam is filled with polyurethane foam.
- A heat-insulating tube is embedded in the foam that has not yet hardened.
- The tube foams on top. After hardening, excess polyurethane foam is cut off.
- The entire joint is sealed with sealant.
When installing insulation, its joints must not coincide with the joints of the panels. It's better to do everything overlapping.
Reinforcement
Polystyrene foam does not require panel materials like mineral wool. However, this is a fragile material, so it is covered with plaster. To do this, the insulation is reinforced, after which the iron mesh is attached to the surface using dowels.
Figure 5. External wall insulation. For multi-storey buildings, reinforcement is done end-to-end. The lap process can cause the plaster layer to delaminate. As preparation for reinforcement holes are created for the dowels. After the mesh is tensioned, pins are driven into these holes.
Padding
The reinforced surface must be primed before puttying. It is better to apply the primer in 3 layers, and plaster immediately after drying.
Plaster
Plastering and painting, allows you to hide foam plastic under a beautiful facade. Not a single person will notice the joints between the panels of the house or the insulation sheets. At the same time, the house will look updated, as if after a major renovation.
Painting
Paint the plaster with waterproof paints. If the insulation budget is large enough, then you can use insulating paint to secure the material. However, this pleasure is not cheap, so you should think twice about such expenses.
Particularly difficult sections of walls
Particularly difficult areas are corners and windows. To insulate corners must be sealed. You will have to install high-quality double-glazed windows in the window openings, and still cover the end parts with foam plastic, followed by reinforcement and plaster. Don't forget that after final finishing, the facade of the building should look like a single whole.
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.
Insulation of walls in panel house
Advantages of wall insulation
External insulation of the house This will not only prevent heat leakage through the walls, but will also protect the façade 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:
No need for a while repair work evict residents from the house,
Increasing the temperature inside the building by protecting walls from freezing and other adverse effects of weather conditions,
No resizing interior spaces- the living area is completely 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.
Stages and processes of facade insulation
Depending on the chosen insulation method, installation will vary. There are two main technologies:
Wet Facade
Ventilated facade
Insulation of house walls wet facade
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 are foamed with polyurethane foam and the cracks are coated.
Uneven surfaces of the walls are allowed within 1 - 2 cm, but no more.
After cleaning and processing the joints, the walls are left to dry.
Attaching heat-insulating material to walls is possible in four options:
On glue (cement base)
- glue foam in cans
For fasteners (dowels, plastic nails),
Combining glue with fasteners.
For example, polystyrene foam is fixed using a combined method from the first floor to the upper ones. A starting strip is installed at the bottom, from which the insulation begins to be glued.
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 by level.
It is possible to correct minor errors before the adhesive base sets. Now you need to wait 1 - 2 days, depending on weather conditions, so that the glue dries completely and the insulation is well fixed on 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.
Installation of polystyrene foam with adhesive foam
It is done three times faster due to the setting of the adhesive foam within 20 minutes, thus the foam is glued using adhesive foam. The foam is applied to the foam, and the unevenness and voids are also perfectly sealed and filled, then fixed with mounting dowels using a puncher. The procedure for gluing polystyrene foam boards are made from the bottom up.
Pinning the grid
To give strength and rigidity to the insulation elements, it is reinforced. 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 adhesive layer is applied for leveling. After installing the mesh throughout the house, wait for the glue to dry.
The reinforcement provides mechanical stability for the final decorative covering panel house.

The suddenly increased relevance of insulating the facade of an apartment is, in particular, associated with the rapid rise in prices for energy resources and housing and communal services tariffs, which necessitates the need to save money, and more. effective consumption heating resources.
The problem is that most of those currently in use apartment buildings were built almost half a century ago, and their thermal insulation is not nearly as effective as their owners would like.
Statistics show that heat loss through the walls of a house reaches 50% percent of total number heat loss, which, you see, is more than significant. This indicator primarily depends on the design features of the house itself, for panel houses it is maximum, for brick ones it is slightly less.
Insulation of apartment facades is beneficial, no matter which way you look at it, if you have heating system, then you can save about 20% of the amount previously spent on gas consumption, and if you are connected to central heating– then the average temperature in the room will increase by at least 3-4 degrees (and if you set it, by 5-6).
1 Legal features
According to federal laws, unauthorized change of the facade apartment building is prohibited, therefore, in order to insulate the walls of an apartment, you will need to obtain permission from the relevant authorities (housing and communal services).
Usually, obtaining a permit is not accompanied by any special difficulties; to do this, you just need to go to the housing and communal services department and talk with the people responsible for this; sometimes you may need to write a petition in your own hand, which indicates that all responsibility for the safety of wall insulation work is on multi-storey building choose for yourself. However, there are situations in which insulation can be refused.
As a rule, it is difficult to obtain permission to insulate the facades of new houses located in the city center. If you refuse, the only thing left for you is to start insulating the walls from inside the house, which can also provide high efficiency thermal insulation of the apartment.
Moreover, joint insulation of facades with is much better in purely technical terms, since the occurrence of a dew point is prevented, which is formed due to the difference in the freezing temperature of insulated and non-insulated sections of facades, as a result of which the walls of the apartment expand and contract in different ways, which can threaten their acceleration destruction.
Also, if the technology for insulating the walls outside the apartment is incorrect, moisture can get under the insulation, which, when freezing in the cold season, expands and peels off the heat-insulating material from the wall of the house. As you understand, monolithic insulation installed for several apartments at once is less afraid of such troubles.
1.1 Selection of performers
As a rule, all work on insulating the facades of multi-storey buildings is carried out by special companies or industrial climbers. Therefore, it is very important to choose the right contractor who has the necessary knowledge, experience, and all the required permits.
Since insulating the walls of an apartment from the outside is related to high-altitude work, which is directly related to risk, do not be surprised that the cost of paying the contractor will exceed the total cost of materials for the work - professional industrial climbers know the price of their work, and, as a rule, do not work for cheap.
Be sure to require that the performer show you documents such as “License to conduct construction work" and "Permit to carry out high-altitude work", it would also be a good idea to find out feedback from previous clients of this company or a team of workers - whether they are satisfied with the result, how long it took to insulate the walls of the apartment, how the contractor approaches the performance of his duties, etc.
It is also recommended to check with the contractor the addresses of houses in which they have already performed similar work with, and go and look at the quality of the facade insulation. Such precautions, although they take a lot of time, will help you avoid many problems associated with unscrupulous performers in the future.
Once the contractor has been selected, he must draw up project documentation related to the specifics of the work, namely:
- Drawings of apartment facades, with detailed dimensions window frames, cornices, and others architectural elements, present outside the house;
- Data on the boundary loads that the walls of the house may experience;
- Thermal insulation class of the walls of the house - this point is the starting point when choosing the material used to insulate the walls of the apartment both outside and inside.
2 Selection of thermal insulation material
Insulation of apartment facades can be done with the following materials:
- Foam plastic;
- Expanded polystyrene;
- Mineral wool (very effective);
- Foam glass.
Each of these heat insulators has its own advantages and disadvantages, which determine the relevance of their use in a specific situation.
Foam insulation is the most budget-friendly, and therefore the most common option. Polystyrene foam can be used to insulate anything and anywhere, even when the effectiveness of a given heat insulator will obviously be lacking. The pursuit of cheapness is the main mistake of most people, since using low-quality thermal insulators you will not get the expected effect from insulation.
In general, if the walls initially have a normal thermal insulation class, then insulating the outside of the building with foam plastic may be quite sufficient. If you decide to insulate your house with polystyrene foam, keep in mind that the higher the density of this material, the less heat-conducting properties it has, and, as a result, it is better suited for insulation.
Expanded polystyrene is also quite inexpensive material, and, at the same time, its thermal insulation properties are an order of magnitude better than those of conventional polystyrene foam.
The advantages of this material include minimal weight, ease of installation (it is excellent for cladding corner apartment), and hydrophobicity - polystyrene foam does not actually absorb water, which has a positive effect on its service life.
The disadvantages of expanded polystyrene are the following: instability to fire (requires the installation of special fire protection jumpers), and lack of sound insulation. Expanded polystyrene, in general, is excellent for both thermal insulation of walls outside and inside the house.
Mineral wool is one of the most effective insulation materials, however, the cost of this material significantly exceeds the cost of analogues, therefore, it is used quite rarely for thermal insulation of facades.
The advantages of mineral wool include fire safety (the material does not burn), hydrophobicity, and good sound insulation properties. Mineral wool has only one significant drawback - its relatively large weight, as a result of which its installation on the facade of a building is carried out with big amount fastenings (dowels).
Foam glass is the most expensive material used to insulate apartment facades. If you are not limited in funds, then you should give preference to it, since this insulation has excellent thermal insulation properties, durability, and hydrophobicity. Foam glass does not burn, it does not harbor fungus, mold, or other microorganisms.
In addition to the insulation itself, you will need to purchase a large number of related materials, such as:
- Construction adhesive, liquid polystyrene foam, dowels - for fastening;
- Plaster mixture - to level the surface;
- Primer – for additional waterproofing insulation, and for better adhesion of plaster with paint;
- Mesh for reinforcement - to strengthen the plaster layer;
- Facade paints for - as a rule, housing and communal services require that the insulation be painted with paint that matches the main color of the building.
Payment to the contractor is made upon completion of all work, according to a report drawn up by the foreman, which indicates the entire range of work performed, and the individual cost of each element.
They are used for insulation of pipelines.
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 of a 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 on 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 possible or Money there is no need to insulate both outside and inside, then in this case the most optimal solution work will be carried out 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.
It is best to choose external insulation, since in this case not only the premises themselves will be reliably protected from the penetration of cold, but also the walls themselves will be well protected from the cold, which is considered the most effective and correct solution.
Internal insulation will ensure the creation of a thermal insulation layer that will protect the premises from the cold that is already penetrating through the walls of the house.
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 around the entire perimeter of the wall, and slabs are laid in its cavity thermal insulation materials, 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 against the background of the overall decoration of the house. With this design you can actually get perfect result work, 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 at a fairly high altitude, as a result of which you will have to constantly use special equipment for work.
Another method of external insulation is to create a heat-insulating layer on the walls of the house, which is then covered with a layer of plaster. This method is considered quite effective and efficient, as well as simpler and faster, and at the same time you can handle all the work quite easily with your own hands. However, you should first evaluate the wall for the presence of any defects or all kinds of obstacles to applying a plaster layer to the walls. The fact is that it is often simply impossible to carry out the planned work due to the presence of significant obstacles to this. In this case, you will have to create curtain façade. However, if there are no barriers to applying plaster, then you can proceed with insulation using this method. To do this, initially waterproofing materials begin to be fixed on the outer walls of the building, and it is advisable to choose special unique membranes for this, which will not only protect the walls from the penetration of moisture from the outside, but will also additionally allow steam and moisture to pass from the walls. After this, you can begin to fix the layer of foam plastic or mineral wool, however, in the latter case, it is advisable to additionally wrap each slab waterproofing materials. The fact is that this insulation does not have any resistance to moisture, which can even cause damage to the material or the fact that it will no longer cope with its main tasks. Fastening can be done using a special and reliable polyurethane glue or using dowels, and experts say that the best work result can only be achieved using a combination of these fastening methods. However, this can only be done for polystyrene foam, which has quite high density. As soon as thermal insulation layer will be fully formed on the walls of the house, you can begin to create a decorative layer, for which it is used decorative plaster, intended for outdoor use. You can also install siding using suitable fasteners. The specific choice depends entirely on what specific goals are intended to be achieved with the help of insulation, since it is often important not only to insulate the walls of the house, but even to decorate them, as well as to give them an updated and interesting appearance.
Features of internal insulation
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, on which last stage works are applied any suitable 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.
Thus, insulating the walls of a panel house is considered a very simple and quick job, which you can easily do with your own hands, and at the same time you can independently choose which insulation method will be used.
