Today, the insulation of the facade walls has become almost mandatory for every house. Prices for utilities are rising at an unthinkable speed. Therefore, far-sighted masters prefer to invest resources once in warming the house and forget about high tariffs for good.

Warming outside and inside
In our review, we tried to answer the emerging questions when warming the walls of your house. How best to insulate – outside or inside? What material is more correct to work on insulation – foam or mineral wool (mineral wool)? How difficult is the process of warming to produce it yourself? Also, together with this, we demonstrated a photo of our works for more than 14 years of practice of reconstructing the facades of private, country and city houses and buildings in the form of a photo before and after warming.
Wall insulation can be done from inside as well as outside the house. The facades of new apartment buildings are insulated from outside with the help of mineral wool or polystyrene. However, in old houses the walls are not insulated at all, and the residents are freezing in winter. Some owners of apartments order a separate external insulation only for their apartment. After that, the temperature in the rooms rises just a few degrees.
But in the external insulation of individual apartments there are downsides. Condensate accumulates at the junctions between the insulated and unheated zone, and in the neighboring apartments mold can form.
In which cases it is impossible to warm the facades:
- the building has a historical value, therefore the facade change is forbidden;
- the facade is decorated with small decorative elements. The application of a layer of insulation is difficult.
Have you decided to insulate the walls of the house? Address to the expert. He will determine the thickness of the insulation layer, which directly depends on the material of the walls. The cost of work includes not only a heater, but also accessories: plaster, dowels, paint, etc.
Which insulation should I choose
It is better to warm the house from the outside with mineral wool. For internal insulation, this material is not suitable, because its microparticles are harmful to health. But as an external insulation mineral wool shows a number of advantages. It is unstable to moisture, but practically does not burn.
Insulation of the facade can be done with glass wool. In its properties, this material is similar to mineral wool. However, the glass wool is very fragile and eventually shrinks. Polyfoam is resistant to moisture, conducts heat well. However, this material is flammable and not too durable. Foam plastic like mice. Therefore, there is a risk of detecting in the layer of the heater the traces of sharp teeth and even burrows.
Insulation of walls with foam plastic can be done by oneself. This material is inexpensive, light in weight. The only condition – foam is preferably not used in areas with hot climates. Although in a hot climate, a heater is not needed at all.
Insulation the house with your own hands
Insulation the house with foam does not require special building skills. It is better to choose sheets of medium thickness. Calculate the area of construction works. Take away from it the area of windows and door panels. Add a few centimeters to the slopes. And get to work. Buy special glue for polystyrene and large dowels length equal to the height of two sheets of polystyrene laid on top of each other. Or even a little longer. Buy materials with a margin.
Insulation the house with your own hands you need to start with the preparation of the walls. They must be cleaned, leveled and primed. The glue is applied with a special notched trowel. The thickness of the layer is about one centimeter. Sheets on the wall must be glued in staggered order. The distance between them must be minimized as much as possible.
After gluing, fix each sheet of foam plastic with dowels. Count on that on one sheet of foam you will have five dowels – four on the edges and one in the center. After reinforcement, the foam should be reinforced with a mesh. Apply a thick layer of glue on the sheets, cover with a mesh and carefully smooth it. Strengthen the corners.
Insulation of the house from the inside is done in a completely different way. Usually styrofoam is used. However, the best material for internal insulation of walls is polyurethane foam. It does not get wet at all, so its use does not require waterproofing. Polyurethane foam does not need to be glued or mounted inside special profiles. The material is sprayed directly onto the wall. It freezes in a few seconds. Polyurethane foam can easily be sprayed even on the ceiling and other hard-to-reach places.

Thermal insulation of the facade today is almost mandatory for every owner. Prices for utilities are rising at a tremendous rate. Therefore, practical owners invest significant resources in the insulation of walls in order to avoid large monthly payments.
How and why to warm the house
Warming the house with your own hands can be done from the inside and outside. Facades are usually insulated with mineral wool or polystyrene. In the old houses, where the walls are not insulated at all, and the residents freeze in winter, the owners set up facade insulation for individual apartments. After that, the room becomes much warmer. The temperature rises at once several degrees. However, moisture accumulates on the edges of the foam plates and joints. Therefore, in neighboring apartments often appears mold.
Experts agree that it is much better to insulate the house from the outside, not inside. In which cases this is impossible:
- changing the facade of the building is prohibited by law. This happens if the house has a historical value;
- it is impossible to glue the insulation due to the small decoration of the external walls.
Warming with mineral wool and thermopanels
How to start warming the house with mineral wool? Best of all – by contacting a specialist. He will determine the thickness of the insulation layer, which directly depends on the material of the walls. The total price of the work includes not only the heater itself, but also the consumables: plaster, dowels, paint. Warming of the house, photo of which is on our website, it is better to produce with the help of mineral wool. For internal insulation, this material is not suitable because of harm to health. But for outdoor insulation mineral wool is excellent. Unconditional plus mineral wool is that it does not burn.
Thermal insulation of the house by thermopanels has recently become very popular. Thermal panels – a plate of foam or polyurethane, covered with marble chips and binders. This coating has two functions simultaneously – protective and decorative. Thermal panels are glued to the walls like ordinary tiles. For the installation of thermal panels do not need dowels, reinforcing mesh, plaster. They are applied exclusively to glue. Thermal panels do not burn out in the sun. In the bright light, they gleam a little.
Why you should not insulate walls from the inside
Warming the house from the inside is not recommended by specialists. If the house can not be insulated from the outside, then there is no other way out – you need to insulate from the inside. As a material for internal insulation, polystyrene is often used. And the best option is polyurethane foam. He does not get wet, he does not need waterproofing. Polyurethane foam does not need to be glued or mounted on profiles. The material is sprayed directly onto the wall. It freezes in a few seconds. Thanks to a convenient spray, polyurethane foam can easily be applied to hard-to-reach places, including the ceiling.
Despite the apparent ease of mounting the insulation panels from inside the apartment, this task is very difficult. Without the help of specialists you can not do. If the technology is not respected, a mold can be formed on the walls. It’s very difficult to get rid of. The fact is that with internal insulation, the outer wall of the building remains cold. Over time, it can become covered with cracks and even completely collapse. In the case of a successful solution of technological problems, the application to the internal walls of the insulation layer does not differ from the way of installing the insulation on the external walls. Plates of foam plastic or mineral wool are glued with special glue on the previously cleaned walls. Then they are fixed with long dowels and reinforced with a grid. The top is applied with a bactericide primer and a finishing coat.
It is much better if the insulation plates do not stick to the inner wall of the apartment, but are mounted on the profiles. In this case, a ventilated gap remains between the heater and the wall. Mold in it is not formed.

What is the best way to warm the walls? What material should I use? Is it possible to insulate the facade on its own? These and other similar questions you ask yourself every time you get a monthly receipt for heating and gas supply.
How to insulate walls
Warming of walls inside is recommended to be carried out only in those cases when external insulation of the facade is impossible. There are several reasons for this situation. For example, the building is of historical value, it is forbidden to change its facade. Or the facade is decorated with a small decoration, which prevents the application of a warming layer.
In other cases it is better to make external insulation of walls. Kiev – a city with a lot of old Khrushchev and Panelek. Every third house must be insulated in the capital. Most often, mineral wool is used to insulate new apartment buildings. It perfectly keeps heat and does not burn. Mineral wool also has excellent sound-absorbing properties.
In private homes, it is also desirable to make the walls warm. The price of foam plates is quite low. Polyfoam can be used to insulate the façade by yourself. To do this, you need to measure the surface area of work and purchase building materials. Carefully prepare the walls. They must be leveled, cleaned and treated with a primer.
Wall warming in the home
Have you decided to make the insulation of the walls by polystyrene foam? The price of such works is quite reasonable. Buy plates of medium thickness. It is better to use special glue for polystyrene foam. Apply glue to the wall with a special notched trowel. The thickness of the adhesive layer is one centimeter. Lay the sheets of stucco in staggered order on the glue. The distance between the plates should be minimized as much as possible.
The insulation of the walls with polystyrene from the outside is carried out using reinforced mesh. It is applied to a layer of glue that is applied over the foam sheets. Choose foam, which is impregnated with a substance that prevents combustion. Fix the sheets of polystyrene with long dowels. Then cover the layer of insulation with plaster. Experts recommend to apply the plaster in two layers. The second layer is laid after the first one dries completely. The outer layer of the plaster must be carefully processed and prepared for applying the final cladding.
The best materials for insulation
The walls are warmed from outside in dry weather. If you work in the summer heat, the glue will dry quickly. This must be avoided. Slots and gaps between the plates must be laid with foam, and the smallest – sealed with a mounting foam. Thermal insulation of walls with polystyrene with their own hands does not end there. Particular attention should be given to gluing reinforcing mesh and plastering. The dowel-fastened sheets of foam are greased with a thick layer of glue. A synthetic mesh is attached to it. It must be quickly smoothed out until the glue is dry. The edges of the grid are overlapped. After that, the first layer of plaster is applied to the mesh.
Warming of walls with mineral wool is not recommended. It releases harmful microparticles. Excellent material for insulation of facades – panels made of foamed polyurethane. Such panels are durable, waterproof, have low thermal conductivity. They do not burn, do not rot and do not age. And also do not require almost no care. Panels made of foamed polyurethane are fastened to the crate. Polyurethane keeps the heat well, therefore it is not necessary to heat the walls. The exception is the northern regions, in which the porosity reaches fifty degrees.
New insulation materials appear on the building materials market almost every year. And every year they become more and more durable, high-quality and modern. For example, liquid ceramic insulation. This is one of the most modern and high-tech materials for insulation. Particular attention should be paid to environmentally friendly materials – straw and cane mixed with clay. However, these materials on the market are not yet widely represented. After you have decided on the material for insulation, you should calculate the price. It depends on the surface area of the work and the number of materials used. Well, then you need to decide whether you will insulate the facade yourself or contact a specialist.

Finishing the walls with polystyrene does not require the owner of the house almost no skills in construction. Prepare for work on the insulation of external walls is very simple. First you need to find out how much material you need. To do this, you need to calculate the area of construction work, take away the area of window and door openings, and add a couple of centimeters for the slopes.
Preparation and process technology
After calculating the required amount of material, you can proceed with the purchase. What you need to buy:
- sheets of foam of average thickness;
- special glue for polystyrene foam;
- long dowels at the rate of five pieces per one foam board.
- How best to make the insulation of walls with polystyrene outside? Video, shot by a specialist, can answer many questions. For example, there are special features in the application of glue.
- The glue must be applied with a notched trowel. It is possible to apply and a usual spatula, but in the end it is necessary to process a surface with a gear tool. The thickness of the adhesive layer should be at least one centimeter.
The best way to explore the insulation of walls with polystyrene outside is the reviews. Experts say that the sheets are glued to the wall in a chessboard pattern resembling a brickwork. You need to start from the bottom. After the masonry is finished, the glue should dry completely. It is desirable to additionally fix the plates of polystyrene with the help of long dowels. Do this after the glue has completely dried. Nail the anchor into the center of the foam sheet. Another four dowels nail in the corners.
Use of reinforcing mesh and foam
Have you decided to hire specialists to carry out the insulation of the walls with foam plastic from the outside? The price of professional services is quite high. You can insulate the facade yourself. When the walls are completely covered with polystyrene, and each sheet is fastened with five dowels, proceed to pasting the reinforcing mesh. The mesh is fixed to a thick layer of glue and immediately carefully smoothed. The edges of the grid overlap each other. Do this quickly, until the glue is dry.
The best way to learn how to glue foam on an uneven wall is video. Before insulating the wall, it must be prepared: clean and align. See how the master pastes the plates end-to-end. The distance between the sheets should be minimal. The slots between the slabs of foam are sealed with a mounting foam. The reinforcing mesh is covered with plaster. The plaster is applied in two layers – the second layer is placed after the first one has dried completely. The final layer of plaster must be aligned as much as possible to prepare for the facial finish.
How correctly to make warming of the house by a foam plastic? The price for the services of specialists is quite high. However, the owner can insulate the walls on his own. You need to do this in dry, but not hot weather. In the summer heat the glue dries too quickly. It is necessary to avoid getting moisture on the walls until the plaster dries completely.
Advantages and disadvantages of foam plastic
What else do you need to know before starting to insulate the house with polystyrene foam? Pros and cons of this material are known. Let’s start with the pluses. Polyfoam is very light, the use of this material does not require additional reinforcement of the foundation. The process of external insulation with foam plastic is simple. It can be done on its own. The price of the material is not high. Now let’s move on to the minuses. Polyfoam is a combustible material. This is his main and only drawback.
Insulation of foam from the inside – what are the pros and cons? This process is similar to external insulation. Plates of foam plastic are glued to the walls and additionally fixed with dowels. Foam sheets are stacked in staggered order, and dowels are hammered into the wall after the glue has dried completely. Reinforcing mesh is not required. Polystyrene is an inexpensive and lightweight material. With it you can work without additional means of protection. Polyfoam does not pollute the apartment, it is easy to remove. Between the foam and the wall it is necessary to lay a waterproofing layer. This can be a conventional polyethylene film or other modern waterproofing material.

Thermal insulation of the house with polystyrene is very popular among owners of own houses. This will not only save you considerable money during the installation phase, but during the heating period you will pay a much smaller amount than your neighbors. Polyfoam is ideal for warming homes that are in areas with hot summers and cold winters. Due to its thermal insulation characteristics, it keeps heat in cold weather, and when the heat in the room creates the optimum temperature.
Choosing between the insulation of walls from the outside or inside, you should consider two points. With internal insulation you reduce the interior of the room, which can significantly affect some rooms. If the insulation is external, the dew point is outside the house, so the walls will not freeze.
In addition, styrofoam is widely represented in the market of building materials, and it is his developers who use most often. Therefore, with the warming of the walls, you save money at all stages – during the purchase of materials, during installation and during operation.
Thermal insulation of house foam: the pros and cons
Advantages of this material:
- low price;
- because of the high air content, the foam does not conduct heat well, therefore it is one of the best heat-insulating materials;
- thanks to the air the material is light, it is convenient to carry one, the cutting process is very simple (you can cut the sheet directly in the room where it will be mounted);
- walls can be insulated both outside and inside;
- with internal installation, the walls do not thicken much;
- the material does not rot or fungus;
- you do not need special skills to install it.
- along with its ease, the material is fragile enough, so it requires additional reinforcement (often using reinforcing mesh and plaster);
- not suitable for certain types of finishing works, is destroyed under the influence of certain paintwork products;
- material is highly flammable;
- if the house has mice or rats, it is not recommended to use polystyrene for warming – rodents easily gnaw it.
What materials to choose?
Half of the success lies in properly selected, quality building materials. First you need to choose a foam. You do not need to take the thickest and thickest material. For the insulation of the house, medium density and thickness sheets are suitable. If you doubt what thickness and density will suit you – it is better to consult the seller.
When buying glue, pay attention to what it is intended for. You can take ordinary building glue, but glue for polystyrene is much more reliable. So you will be sure that the foam is densely and securely glued to the wall. To further strengthen the foam sheets in the wall, use umbrellas. How to find out what and in what quantity you will need? Their length should be equal to two thicknesses of foam, and on one sheet there are 5 pieces of “umbrellas”.
Mounting of insulation
The following tips will tell you how to insulate the house with polystyrene from the outside so that it will not only be quick, but also qualitatively. First you need to prepare the walls. This will determine how tightly the foam will adhere to the wall, whether it will hold securely. Therefore, the material can be fixed only on a clean, primed and necessarily leveled wall. Next, a 1 cm thick adhesive is applied to the sheet and carefully distributed throughout the sheet. Foam is fixed to the wall strictly in staggered order, it is important to make sure that the gap between the sheets is minimal.
To extend the life of the plant, it is necessary to use umbrellas. They are fastened easily – four in each corner and one in the center. For their installation it is better to take a punch. Then the foam should be reinforced with a mesh. To do this, a thick layer of glue is applied to the material, into which the mesh is heated. And in the end you need to plaster the wall. It is best to do this twice, so the surface is better leveled and ready for painting.
Design of house facades with insulation (photo examples)
In modern Ukraine, lean owners of houses and apartments massively insulate the walls. This is done to save energy and save money on utilities. City in which the facades are massively insulated – Kiev. The price of similar work depends on the surface area and materials used. There are a lot of old houses and a fairly cold climate. In order not to freeze in winter, the owners of the apartments warm the walls both from inside and outside.
Prices for the insulation of facades in Kiev
Warming of facades with foam plastic is an excellent budget option. This material is inexpensive, easy, easy to use. For a private home, insulation with polystyrene foam is an excellent solution. Because of its ease, the foam does not require reinforcement of the foundation. It can be fixed on the facade with your own hands.
Are you planning to insulate the facades? The price per sq. M. Depends on the amount and thickness of the foam used. One of the main drawbacks of foam is its flammability. Buy material impregnated with a special substance that prevents combustion. This is indicated on the marking. The price also depends on the amount of work. If you order not only insulation, but also facing, as well as the final decoration of the facade, the price accordingly increases.
Thermal insulation of facades, walls of apartments in Kiev are made by specialists in high-altitude works. There are many high-rise buildings in the capital. New houses are built immediately with the warming of the walls. And the old houses need to be insulated by the residents themselves. If the height of the house is more than ten floors, gluing sheets of polystyrene, plastering and painting are very difficult.
How to insulate the house yourself
Warming of the facades with your own hands is possible only in a private house. If your cottage has two or three floors, you can not do without scaffolding. Today, lightweight and durable scaffolds are produced from a variety of alloys. They can be rented. Do not use wooden forests. They are usually very old. Such forests pose a danger to life and health. They can collapse at any time.
Warming of facades with mineral wool necessarily requires professional knowledge, as well as skills of construction work. Mineral wool has a number of advantages over polystyrene. The main advantages are incombustibility and high sound-insulating properties. Before walling the mineral wool layer, the walls should be treated. The technology of cleaning the walls is common for cotton wool and for polystyrene foam. However, there are differences. Before the insulation with mineral wool from the wall, it is necessary to remove all sticking metal surfaces – nail heads, fragments of reinforcement. Otherwise, the beautiful facade will very soon be covered with rust stains. Before fixing the mineral wool, it is necessary to mark the walls with a kapron cord. It stretches between the pieces of reinforcement that are driven into the wall, which must then be removed.
How to properly insulate the house
To support the lower row of plates a plinth is used. It is mounted using dowels. To fix the sheets of mineral wool, only glue intended for this material should be used.
Mineral cotton wool sheets are laid with a seam shift, as in brickwork. We must try to put the sheets so that there is not even a minimum gap between them. The technology of applying glue and fixing mineral wool slabs is similar to work with foam plastic. The contact of microparticles of the material on the skin and in the nose causes unpleasant sensations. When working, use durable closed clothing and a respirator. The plates are fixed with long dowels. Pits from dowels must be plastered before gluing reinforcing mesh. First lay the central plate of mineral wool. Window and doorways are insulated in the last place. The peculiarity of the facade insulation depends on the final cladding. If the facade is planned to be siding, then a space for ventilation is usually left between it and the heater. If the final finish is plaster, the sheets of reinforcing mesh must be overlapped with a width of at least ten centimeters.
Wall insulation foam with your hands
Thermal insulation of the facade with foam plastic does not require practically any special skills of construction work. However, before you start working, you need to carefully prepare:
- clean the walls of dirt;
- plaster cracks and irregularities;
- buy the necessary materials.
How do I know how much polystyrene is needed? It is necessary to calculate the surface area of the walls. Take away the area of the door and window openings. Then add 10% as a stock.
Materials and Tools
You will need sheets of polystyrene of medium thickness, special glue for this material and long dowels. The usual building glue will not work for you. We need just the glue for the foam plastic. After calculating the area of the walls, go to the building store. How best to arrange the insulation of walls with foam plastic with their own hands? The video will help answer many questions. The nonspecialists have a lot of problems with applying glue. It must be applied with a notched trowel. The glue layer should be thick – from one centimeter and more.
The best way to learn insulation of a house with polystyrene is video. The main thing you need to know about technology is the stamping of plates. This prevents the formation of bridges of cold. Begin the masonry always from below, from the foundation. After the end of the work, take a break. The glue must dry completely. However, one glue is not enough. It is necessary to fix the insulation with dowels. How many dowels do I need? Five pieces per sheet of foam. Start from the center. Nail the anchor in the middle of the sheet, and then fix the plate in the corners.
How to additionally strengthen the wall
How best to examine the insulation of the house with polystyrene foam? Feedback from those who have already done it will help you. Experts advise to further strengthen the wall reinforcing mesh of fiberglass. After fixing the foam plastic dowels, apply a thick layer of glue on it and glue the net. Its edges must overlap. Quickly smooth the mesh, otherwise the glue will dry out and you can not do it.
How to insulate the house with foam plastic from the outside? The master always pastes the plates end-to-end, as close to each other as possible. What if there are gaps between the plates? Wide gaps should be laid with pieces of foam, and narrow – sealed with mounting foam.
Over the reinforcing mesh should put a layer of plaster. Some masters advise to put two layers of plaster. If you are going to use this advice, first completely dry the initial layer, and then proceed to apply the next one. The plaster must be carefully leveled for a quality finishing coat. How to glue foam on an uneven wall? The video will answer this question. Some experts recommend that the walls be leveled with polyurethane foam or liquid foam. A proven method is preliminary leveling of walls by plastering.
What is the best way to make the house insulated with polystyrene foam? The price of the material is low, but the services of specialists are more expensive. If the owner undertook to insulate the walls himself, then it is desirable to do this in dry weather. In the summer heat, the glue dries up too quickly, so it is best to begin warming the facade in the spring or autumn. Avoid wetting the wall until the plaster dries.
How to insulate the house from the inside
Insulation of foam from the inside is very easy – much easier than outside. The processes themselves are very similar – sheets of foam are glued, and after the glue is completely dried, they are also fixed with dowels. The sheets of styrofoam fit in a staggered pattern like brickwork. In the case of internal insulation, you can do without a reinforcing mesh.
Polyfoam is an excellent material for the insulation of walls both outside and inside the premises. It is very light and, in addition, very inexpensive. It can be cut very simply with an ordinary knife. It is environmentally friendly and safe. During work with polystyrene, the apartment is practically not contaminated. This material has a lot of pluses. But there are also disadvantages. For example, polystyrene burns. The use of this material indoors requires additional waterproofing. However, this is not a big problem, because conventional polyethylene film can be used.
Thermal insulation of the house with polystyrene
When walls easily let heat out, and in winter the heating bill is immensely huge, the question arises of how to fix this situation. The most correct option – home insulation foam, the price of which is minimal, and the result exceeds all expectations
So, having covered the house with this material, you will be warm, and at the same time save on heating. In addition, there are a number of reasons why you should choose polystyrene foam:
- moisture resistance, you do not have to additionally insulate the wall to avoid the accumulation of water;
- lightness, so you can independently process, cut off and attach a sheet to the wall;
- due to the small weight, the load on the wall is minimal;
- does not appear fungus, mold;
- is resistant to any temperature changes, so in the winter it keeps heat in the room, and in summer it equalizes the temperature to a comfortable one.
If there is a question about choosing a heater for walls – polystyrene or mineral wool, then choose the first material. It is waterproof, it is much easier and more convenient to work with, in the future, when operating, there will be no problems with deterioration of thermal insulation.
How to insulate the house with foam plastic from the outside
First, it is necessary to apply a primer, to level the wall, thus, the sheets will be more securely held. Before gluing foam on the bottom edge of the wall, a metal strap is attached. It is she who will hold the first row and will not let him fall.
The next step is applying glue. It can be applied in several ways:
- On the wall, the glue is applied, if there are small roughnesses, it needs to be done gradually so that the glue does not dry out;
- most often the glue is applied to the material itself – it is convenient not only if there are wall irregularities, but also if you work with foam for the first time;
- The glue from the can is applied directly to the heat insulator, which you just need to press against the wall.
After gluing the sheets, you need to use special dowels, which look like an umbrella. The leg should be equal to two thicknesses of the sheet in order to securely and firmly fix the heat insulator, the cap will hold it firmly. Screw one dowel per angle and one center. After you need to carefully work through the remaining cracks. This can be done with a mounting foam (the remains of which are easily cut with a knife) or small pieces of polystyrene foam. Only after that you can proceed to reinforce the foam reinforced mesh. And at the very end you need to thoroughly plaster the surface to get rid of all the irregularities, this will have to be done twice.
Thermal insulation of the house from the inside with foam
Installation inside the room is similar to the exterior of the house, but there are some differences. To begin with, it is also necessary to level the wall, after which it is recommended to apply an antifungal primer. Despite the fact that the foam is not susceptible to fungus, we advise you not to miss this step, because in the room the chance of the appearance of the fungus is much higher than in the street. Next you need to measure what size you need sheets and cut them, respectively, to the measurements. You can do this with any sharp knife right in the room that you are lining up. When all the sheets are prepared on the wall, starting with the floor, glue is applied. Sites with glue should not be too large to prevent glue drying, they should be the same size as the sheets.
After applying the adhesive, a sheet of foam is pressed against the wall. It is important that it is as tight as possible to the wall, so that there are no gaps between them. Just keep an eye on that there are practically no gaps between adjacent sheets. After the adhesive dries completely in the foam, it is necessary to drill the holes for the dowel – one in the center, two in the corners. This will reliably fix the foam, not allowing it to move. In the wide slots are inserted pieces of foam, and the narrow are glued with construction foam (without toluene). In addition, an antifungal agent is applied to the joints.
After the insulation is reinforced with reinforcing mesh, which should be as much as possible drowned in the glue. After the glue has completely dried, the wall can be puttyped, primed and glued wallpaper. Now you know how to glue the foam on the front of the house, how to insulate the room inside.
Wall insulation with mineral wool
Mineral wool is considered one of the best insulation. It is available in three versions: slag wool, glass wool and basalt wool. Basalt wool is made from melted and compacted minerals, such as basalt. Mineral wool is produced in rolls of different thickness.
Varieties of mineral wool and their properties
How to make the warmth of the walls with a mineral wool? The price of materials is low. But the services of the master will not be cheap. However, it is extremely undesirable to insulate walls with mineral wool. This material can be harmful to health. When cutting sheets of mineral wool into the air fall into the tiny particles of stone. Breathing them is harmful.
How to make the walls warming with mineral wool? The video shows all the subtleties of the process. Another version of mineral wool is glass wool. It is made from re-melted glass. The glass wool retains all the operational properties of stone wool, but it also has a number of disadvantages. The glass wool is brittle, it shrinks. Putting glass wool yourself is very harmful to health. Its microparticles have sharp edges. They can scratch the skin and respiratory system.
Warming of the walls with a mineral wool from the inside is undesirable. It is better to insulate the facade from the outside. With internal insulation there is a high probability of mold on the inner surface of the walls. It is extremely difficult to avoid this. If there is a need to put a layer of mineral wool inside the room, you must strictly observe the process technology. Between a wall and a heater it is necessary to lay a waterproofing layer. This can be a conventional polyethylene film or a more modern material. For example, a membrane with a metallized coating.
Fastening of mineral wool on the facade
How to make insulation of facades with mineral wool? The reviews indicate many advantages of this material. The main advantage of mineral wool is that it does not burn. In the construction market there are new modern heaters – very durable and high-quality. For example, liquid ceramic insulation or panels made of foamed polyurethane. Such materials are waterproof, durable, perfectly retain heat. However, mineral wool today is considered one of the best outdoor heaters.
How to mount a mineral wool to the wall? Video will show the process of warming the facade in detail and in detail. Sometimes the mineral wool is attached to the crate. This is a frame that looks like a lattice. In each cell, insert one sheet of insulation and fix it. However, much more often mineral wool to the wall is glued, and then also nailed with dowels. To lay the mineral wool begin from the bottom of the wall, from the corner. Warming of the facade with mineral wool under the plaster must be done using dowels. One glue is not enough. Building glue is sold in two forms of release – a dry mix and diluted glue in cylinders. It is better to use cylinders, despite the fact that they are slightly more expensive than dry mixes. Glue from the balloon is applied at the edges of the sheet and several strips in the middle. Then a sheet of mineral wool should be pressed against the wall.
How to properly insulate the facade under siding
Glue usually dries in an hour. Until this time, the position of insulation sheets on the facade can be adjusted. The diluted dry glue is applied to the sheet in several places, and then evenly distributed over the entire surface.
Dowels are hammered into the walls after the glue has completely dried. In the case of using hard rock wool plates, it is also necessary to drill a hole for the cap. Otherwise, it will protrude above the surface, which will create difficulties in the final lining.
Thermal insulation of facades with mineral wool underneath the siding – not an easy task. In such cases, the preference is given to the mineral wool not in rolls, but in slabs. Before the insulation, the walls must be cleaned and covered with an antifungal solution. Do this because the wall will be insulated from the air after the cladding.
After the solution dries, a vapor-barrier moisture-proof film is attached to the facade. Then the facade is installed metal profile or wooden slats. The cells should be slightly smaller than the mineral wool sheet. The sheets are tightly inserted into the cells. Another layer of vapor barrier film is attached to the heater. And only after that is installed the metal profile of the siding.
Warming inside the house – Material selection
Traditionally, mineral wool is used to warm the walls. Of the advantages should be allocated a small price, easy and quick styling. But in practice the material used does not hold heat well. When laying mineral wool masters often say that this material is well “breathing”. But in fact, that’s why it is not recommended to use this material for warming – moisture easily gets inside. Even when using the best adhesive for installation, any experienced craftsman will say that there is a chance of moisture ingress. If you are wondering “how to strengthen the wall in the apartment from the inside so that it does not turn black?”, The best answer is to refuse using mineral wool. Therefore, today the insulation of the walls from the inside with mineral wool is less often used.
Wall covering with expanded polystyrene
Insulation of walls from the inside with expanded polystyrene has become popular due to the use of inexpensive but high-quality and durable material. Pros of the material:
- high coefficient of thermal resistance;
- does not absorb moisture at all;
- light weight;
- for cutting and mounting, no special devices are required;
- easily tolerates any load.
The use of this material is advantageous due to the fact that, not absorbing moisture, expanded polystyrene retains its properties of the heat insulator. Due to its properties you can use a thin layer of this material, but keep the heat in the room and you do not have to reduce the room. Many manufacturers have facilitated the work during installation – sheets made of expanded polystyrene are manufactured with a stepped edge, which allows you to join the sheets neatly and tightly. So the installation of this material becomes as simple and easy as possible.
Room insulation foam
The wall covering with foam plastic is very economical, not complicated, but labor-intensive. To begin with, you need to purchase suitable high-quality building materials, pick up tools and learn the correct technique of installation. From what you need:
- polystyrene, the advantage of which is a low price, simple processing;
- construction knife;
- building glue.
First you need to prepare the walls. Be sure to make the primer twice, so the foam will lie flat and neat. To a few years you did not have to deal with the problem of poor thermal insulation, your next step should be waterproof. You can use any material convenient for you, the main thing is that the walls were completely covered by it. After the waterproofing, you can proceed to the insulation of the walls from the inside with foam. For fixing, you can use any construction adhesive, most often take mastic. When stacking sheets from the bottom up, make sure that they fit snugly together and there was no gap between them.
In the end, if in some places the sheets do not fit tight enough to each other, use either a mounting foam (for small slits) or small pieces of foam (for larger slots). Thus, you should get a smooth, slat-free wall. When using high-quality materials, with a thorough study of the installation you can do everything yourself. But, if you are afraid that in the future there will be problems with thermal insulation or you can not do everything without errors – we advise you to turn to professionals.
Insulation of walls inside – bad idea!
Internal insulation of the house is not the best option. A more effective way to keep the apartment cozy is to insulate the walls from the outside. However, there are situations when it is impossible to insulate the facade from the outside:
- the facade of the building is recognized as a historical value, therefore it is forbidden to change its appearance at the legislative level;
- features of a design or furnish of a facade do not apply drawing of an external layer of a heater.
Why it is undesirable to insulate walls from the inside
What factors prevent to insulate the house from the inside? This is a physical phenomenon called the dew point. The dew point is the temperature at which warm air cools so much that it turns into water. It is at the dew point that condensation appears. Depending on the method of facade insulation, the dew point can be in the brickwork or in the layer of insulation – external or internal.
With internal insulation, warm air is concentrated in the room, and the dew point is between the heater and the wall. Here, moisture forms. And moisture, as is known, sooner or later leads to the appearance of mold.
What to do if it is necessary to warm the walls from the inside. Video will tell you how best to make this difficult operation. First of all, it is necessary to organize good ventilation in the apartment. The problem of high humidity appears when warm air stagnates in a room, rather than evaporating through a wall into the street. Therefore, it is necessary to ensure the outflow of warm air from the room through special ventilation ways.
Polyfoam and its variants
Insulating walls from the inside with foam plastic is a fairly simple process. You will need only sheets of foam plastic, construction adhesive and a knife to trim the material. Polyfoam is an excellent insulation. It is easy to cut, work with it practically does not leave traces in the apartment. In addition, the foam is relatively inexpensive.
Experts advise to lay a layer of waterproofing between the wall and foam. Most often this is an ordinary polyethylene film. Plates of foam are applied to the glue. You can strengthen them additionally with the help of dowels. Dowels are killed after a few days, when the glue is completely dry.
Insulation of walls from inside with foam is an excellent option for internal insulation of walls. How does penoplex differ from polystyrene foam? Penoplex is a foam that has been melted in a furnace under high pressure. If the foam consists of many small balls, then the foam is a tightly compressed material that looks like a mounting foam. In contrast to white foam, penokleks – bright orange. Penoplex is much better than his colleague. Unlike foam, it does not burn. The only drawback of a penoplex is its high price.
Insulation of walls from the inside with expanded polystyrene is often compared with polystyrene foam. It’s almost the same stuff. Only the technology of its production differs. Styrofoam is more dense, and polystyrene is loose. What is the difference between expanded polystyrene and penoplex? These materials are very similar, they are produced using similar technologies. However, expanded polystyrene is more air-permeable.
The best wall warmers
How to insulate the wall in the apartment from the inside to not black? It is best to use polyurethane foam. It absolutely does not absorb moisture, so when it is used there is no need for waterproofing. Polyurethane foam should not be glued to plaster and fixed with dowels. The material is sprayed directly onto the wall. Penopolyurethane freezes in a few seconds. It is very easy to spray even in the most difficult places, including the ceiling.
Warming of the walls from the inside with mineral wool is possible with some reservations. Mineral cotton wool is divided into three varieties: slag wool, glass wool and stone wool. For internal insulation, only stone wool is suitable. Other varieties are harmful to health. Stone wool is made from remelted and compacted solid rocks and minerals, such as basalt. It is available in rolls.
Mineral wool does not allow water to pass through. When laying it indoors, you must carefully monitor that water vapor does not get between the layer of cotton wool and the wall. For this, a waterproofing is applied-a conventional polyethylene film or a special foil-coated membrane.
When the house is insulated with polystyrene, it is important to remember that with long-term use, the sun’s rays lead to premature destruction of the material. In this case, you need to cover it with special protection. With a professional installation, the insulation of the facades of houses with foam plastic will last you up to 70 years! Extruded polystyrene is also a slab material. Its difference from ordinary polystyrene is that it does not absorb moisture at all, and does not support burning. This makes it more durable than plain styrofoam. It can serve, with a competent installation, more than 70 or 80 years! Its price, on average, is 2.5 times higher than conventional styrofoam. From 2500 UAH per meter cubic. Price – almost the only drawback of this material, so most often it is used for warming the floor and the decoration of the facade. For external insulation of walls – extremely rare, because of its high density, it has a low coefficient of steam exchange. And this, in turn, requires additional work on the installation of special ventilation equipment.
Mineral cotton wool (aka glass wool) is a roll material for the insulation of facades and roofing. The main advantages of this material are low price, ease of installation and transportation. In contrast to polystyrene, glass wools have low density and high water absorption and vapor permeability. When installing, it is important to leave air layers to remove excess condensate. Since, moisture accumulated inside the material, significantly reduces its heat insulation function. Steklovata is less durable than polystyrene. The term of her service is up to 15 years. Basalt or stone wool can be both slab and roll material. Basalt cotton wool is rather low price, so it has a great demand in the market. The price starts from 2200 UAH per cubic meter. The main advantage of the material is absolute incombustibility. Disadvantage – high coefficient of absorbed moisture. Penopolyuretan – the most modern insulation in the market. He does not need additional hydro- and vapor barrier. The material serves for a long time, but it breaks down when direct sunlight hits. Due to the spray application method, it is indispensable, as it easily covers any hard-to-reach places, which can not be said for plate and roll materials. If you just need to warm the walls of the house – foam semi-urethane can be purchased and in the form of finished slabs.
The only drawback of this material is its price, starting from 5000 UAH per cubic meter. In addition to these methods, there is still the insulation of houses and facades with heat pans. This method is new and not very popular in Ukraine. But, despite this, the method is extremely convenient. Ready-to-install panels are delivered from the warehouse to the facility, they can only be installed, besides, they do not require annual restorations. Wall warming is a guaranteed investment in the future. With the rise in prices for gas and heating, the warming of the walls in Kiev is gaining momentum. It not only helps to make the house or apartment warmer and more comfortable, but also increases the efficiency of all heating appliances. After all, no matter how perfect the insulation was, without the walls warming it will “go” outside. If you decide to tackle the warming of the walls with your own hands, the easiest way to do this is using foam. Insulation of walls with polystyrene will reduce your heating costs by approximately 30%. In addition, the technology is very simple, even without any experience, you can manage it yourself.
Advantages of foam for wall insulation inside:
- low price of the material;
- ease of use;
- does not rot;
- environmental friendliness.
The first thing to do is select the material. To do this, make measurements of the surface to be insulated. It is better to buy sheets of polystyrene of medium density and thickness. Next you need to buy glue. Optimal option – a special adhesive for foam. It is worth it, but as a result, you will get a quality wall insulation. The last material is umbrellas. These are special fasteners for polystyrene foam. The optimum length is twice as long as the width of the foam sheets. Also, for the insulation of the walls, a primer, a mesh for plaster and paint angles for the formation of slopes will be needed. The second stage is the preparation of walls for insulation. From the purity and smoothness of the wall depends on how long the insulation will last. Before starting work, they must be cleaned, leveled and covered with a primer.
Then sheets of foam are glued to the wall. The glue must be applied directly on the sheet and the gaps between the sheets should be made as small as possible. After that, additionally fix the foam plastic “umbrellas”, four “umbrellas” on each corner of the sheet. To fix the mesh on the foam, it must be carefully glued with glue. A layer of glue should be enough to “drown” the mesh in it. And the last, but the most laborious stage – plaster of foam. Plastering is desirable in two stages, with a break in one day. The whole process will take from three days to a week. It is important not to hurry up and use high-quality materials, then the walls will be warmed to “cheers”. The insulation of the walls with polystyrene outside is made using the same technology. But it should be taken into account that, given the technical capabilities and terrain, the insulation of the walls from outside can be produced by different materials. In addition to polystyrene, it can be:
- mineral wool;
- “Warm” facade plaster.
Regardless of what material will be used, there are 4 main methods of insulation of walls from the outside:
- method of sputtering.]
Wet method is the standard and most economical method of warming walls in Kiev. The technology is simple. On the cleaned wall with special glue the sheets of foam are glued, further on a thick layer of glue the net is applied, which after drying is covered with putty. Facing method – the most aesthetic, is used in combination with one of the other methods. Walls are warmed with beautiful slabs or special facing brick. Spraying of liquid insulation is the most progressive method for today. Immediately after spraying the insulation, the wall is covered with decorative plates or hinged panels are installed. Methods of exterior wall insulation can be combined according to the customer’s request, and considering all the technical features of the building, to achieve maximum thermal insulation. For each specific case, you can find the best option for price, quality and aesthetic parameters.
Today, residents of all cities of the country are witnessing a constant increase in prices for heating and electricity. In modern conditions, life without these comforts is difficult to imagine. Once a season, all of us, one way or another, are faced with the process of paying bills on new, steadily increasing tariffs. If you look through the accounts for the winter months, we will see that the amount for heating and hot water becomes 2/3 of the amount for payment of utilities in general! Of course, you can put the meters for heating, if you live in an apartment, or a boiler, if – in a private house. But it will not pay for itself and it will be absolutely inefficient, as 40% of all the heat of the house loses through the windows and walls, if they are not insulated! Warming the facades of the walls of apartments and houses will reduce your heating costs by 30-50%! Thermal insulation of facades is the most effective and effective method to make your home warmer, and utility bills are smaller.
Advantages of facade insulation:
- economy – this method does not require large investments;
- durability – manufacturers of different kinds of insulation for walls give a guarantee on their products up to 15 years;
- ecological compatibility – thermal insulation of facades with mineral wool is an environmentally safe method of warming;
- convenience – warming of facades is an external method of warming, therefore the area of rooms does not decrease from volume of a heater, and the fungus does not extend because of absence of temperature drops;
- seasonality – external insulation acts as a cooling material in the summer, which reduces the costs of maintaining the air conditioner;
- protection of the building walls from precipitation, temperature changes and other physical aspects.
The season of external warming of walls, usually, begins in August, and lasts until October. It is during this period that companies for the warming of houses receive a huge number of orders and work as quickly as possible in order to quickly surrender one object and take on the next. We would not recommend that you take up warming at this time, as it is difficult to find a good team, and the prices for materials and services reach their apogee. The best solution is to purchase materials in the winter, when due to low demand their prices are lowered to a minimum, and for the warming to take in the spring. Of all the existing methods, insulation of facades with foam plastic is the simplest and quickest way of warming. Polyfoam is an airy and porous object, it is its pores that become an effective barrier to cold. In addition, the profitability of this material is one of its main advantages.
In addition to polystyrene, for the insulation of the facade of the house, the following methods are used:
- wet method;
- warming of ventilated facade;
- thermal pane insulation.
Warming with mineral wool or polystyrene is a wet method of facade insulation. Warming consists of three layers:
- heat insulation – slabs of foam plastic are attached to the outer walls with the help of “umbrellas”;
- reinforcing layer – on the special glue reinforcing mesh sits;
- decoration – the mesh is primed, then covered with plaster, and the finishing stage – painting.
Ventilated insulation is that a gap is left between the heat insulator and the lining material for free air circulation. This gap fulfills the function of drawing, constantly draining the condensate outwards. Thus, it prevents the formation of fungus and further contributes to the preservation of heat inside the building. Thermal panels are made of foam plastic, mineral wool or extruded polystyrene foam. The advantage of this method is the ease and speed of installation, as the panels already have a finish, decorative coating. The whole procedure is very simple. First, a cleaned outer wall is primed, thermopanels are glued on and sealed. Warming of facades in Kiev is an excellent opportunity to increase the energy efficiency of your house. Housing will not only become warmer, but heating bills will be pleased with its amounts, which will decrease by 30-50%. Tariffs for utilities continue to grow, the cost of heating reaches record levels in a short time. All large heating bills prompt the population to think about warming houses in Kiev and not only.
When deciding on the warming of the house, people immediately get a lot of questions:
- to insulate a wall inside or outside?
- Which heater is better to use?
- Is it worth it to warm the facade?
- What are the prices for warming houses?
Each of the methods has both a number of advantages and a number of shortcomings.
Benefits of warming the house from the inside:
- rapid heating of the house;
- can be performed in parallel with the repair;
- it is possible to conduct house warming by one’s own hands;
- Actually, when you can not change the facade of the house.
- rapid cooling of the house at night;
- during the repair it will be necessary to move;
- decreases the area of the room;
- complex technology, to reduce the condensation of moisture inside the heater;
- need for additional ventilation;
- installation of poor quality threatens the appearance of fungus and mold.
Outside insulation of the house can also highlight its strengths and weaknesses.
Pros of outdoor home insulation:
- prolonged heat retention;
- a stable temperature is maintained;
- in panel houses – solves the problems of sealing the walls;
- the service life of the walls increases, since the heater acts as a barrier between the wall and environmental factors.
Among the disadvantages of outdoor insulation can be noted only the fact that the walls, like the house will warm up longer. But, unlike the internal insulation – they will cool down much longer, and because of this inside the house will always be kept warm.
As you can see, the internal insulation of the house largely loses to the outside. But here there is a weighty factor, when external insulation, or the insulation of the facade of the house, is impossible. This applies to historical and architectural buildings, monuments, where the facade is legally prohibited. But there are very few such buildings, but we are talking more about the insulation of houses. If you live in an apartment building, it will be best to collect the whole house, or at least the entrance and conduct the insulation of the entire external wall. This leveling the probability of destruction of the walls at the joints between insulated and non-insulated walls due to a sharp temperature drop. It is also important to take responsibility for the choice of insulation. It will be best to contact an experienced specialist who will pick up the material and its dimensions, based on your specific case. To insulate the house there is a fairly wide choice of insulation. Everything depends on the walls, your budget and the complexity of the work.
The house can be insulated:
- mineral wool;
- glass wool;
- polystyrene foam;
- expanded polystyrene;
- by a thermist;
- conduct a liquid ceramic insulation.
