Thermal insulation layer under the wallpaper. Selecting and gluing the wallpaper backing

Many people believe that if the question arises about finishing and decorating a wall during renovation, it is enough to just choose the wallpaper you like. However, other important conditions are sound insulation, thermal insulation, and the condition of surfaces. Therefore, special soundproof wallpaper has been created to improve living conditions in the house (prevent negative impact external irritants), which will become simply indispensable assistants during repairs.

There are certain wall coverings (wallpaper backing) that were developed taking into account all the wishes of experienced craftsmen and ordinary consumers. This soundproofing surface is made of polyethylene (foam), which is covered on both sides with special paper. In addition to the paper surface, the backing can be cork or non-woven.

The main advantages of such surface coating are sound insulation and thermal insulation.

Besides this material fits well with any type of wallpaper. That is, such material will allow you to quickly and efficiently decorate walls.

Main advantages:

• Characterized by its high strength, you don’t have to worry about it breaking easily.
• Thanks to the use of environmentally friendly materials for production, it is perfect for any home.
• This special surface does not absorb moisture, but rather helps prevent condensation.
• The sound insulation of this wallpaper helps to achieve comfort and a calm environment.

This roll surface is an excellent material on which to stick the selected wallpaper. Moreover, manufacturers of such substrates have achieved excellent production results. This surface does not lose its properties for many years, which allows you to wallpaper the walls several times.

The wallpaper underlay will prevent the appearance of fungus on the walls for decades, prevent the formation of condensation and provide excellent sound insulation. And besides this, it is ideal for leveling uneven surfaces.

The main producers today are:

1. Ecohit. The material consists of polyethylene foam and has a white paper covering. Thanks to mechanical production, Ecoheat has a more uniform and dense structure.
2. Penolon. This cross-linked polyethylene foam is very popular today.
3. Polyf (trocellen). Thermal insulation is the most undeniable advantage of these wall coverings. These materials stand out for their high quality as well as ease of use.

Characteristics and reviews of masters

All craftsmen involved in finishing and decorating walls very carefully select materials for repairs. This is not surprising, because the length of use of wall coverings depends on the quality of materials.

Therefore, reviews from experienced professionals describe the advantages of using special wallpaper substrates, as well as their disadvantages:

1. Such coatings are not suitable for rooms with high humidity.
2. Be sure to treat the surface of the wall if there is even the slightest manifestation of fungus.
3. Wallpaper that is too thin can show through the hidden backing, so it is better to choose a thicker material for covering walls.
4. Wallpaper underlay cannot completely soundproof a room. Even the most expensive types cannot guarantee this. However, due to its reasonable cost, it is possible to achieve a good result, and noise insulation will become possible.
5. The material is very convenient to use, cuts well and thanks to the paper surface the sheet can be easily glued.
6. The substrate is distinguished by its environmental safety, has no odors, and does not emit dust. That is, it can be used to decorate walls in any room.
7. Such coatings have received excellent reviews due to their ability to increase heat-shielding properties. Therefore, such insulation is indispensable for finishing walls in block houses and dachas.

Whatever substrate is chosen, everyone will be able to appreciate its structural stability. This will allow you to quickly and efficiently level any wall and create an ideal surface for wallpapering.

Thanks to the ease of use of this material, you can quickly achieve excellent results. And you don’t have to be a professional to do this.

How to properly soundproof walls in an apartment under wallpaper

Many may be concerned about the question of how to glue such material correctly and efficiently? Before using the wall underlay, you need to prepare the surface. Old wallpaper should be removed and paint should be removed from the walls. Using a special putty, cracks and cracks are smoothed out. Be sure to treat the entire surface with a primer, this will help get rid of the fungus.

It is important to prepare the material in advance; for this you need to level it. The substrate should be cut into required sizes and put under a press. After this, the inner smooth surface of the canvas is coated with special glue. The adhesive selected is suitable for polystyrene, PVA or intended for heavy wallpaper. The whole process is similar to the usual gluing of rolled sheets, but the sheets are glued end-to-end.

When processing the surface of the substrate, you should not apply glue to the joints, this leads to gluing of the material to each other and after drying the seam may become uneven. It is important to ensure that there are no voids. To get rid of any air bubbles that appear, use a rubber roller to get rid of them.

To ensure that the joints are not noticeable at all, you can seal the seam with thin paper tape. You should not start wallpapering surfaces until the backing is completely dry. This may take 1–2 days.

There are several mandatory conditions for pasting:

• To avoid damaging the quality of the pasting, such work should not be carried out at high air temperatures (no more than 10 degrees). The result can be disappointing, because sometimes certain parts of the sheet do not stick. The best time Autumn or spring is considered to be the time for pasting.
• Wall treatment is a must! A primer or glue is suitable for these purposes.
• After covering the substrate with glue, you should wait a few minutes. Then the sheet will be easier to stick to the wall. In addition, it is important to avoid drafts.

Following these simple rules You can decorate the walls with high quality, take care of the soundproofing of the room and create a cozy atmosphere in the room. And you don’t have to be a professional master.

Description and reviews of the wallpaper substrate

Insulating wall coverings are very popular today, although comments after using them may vary. When describing different wallpaper substrates for insulation and sound insulation, consumer opinions were divided.

Buyers highlight the availability of purchase, ease of use, and with high-quality pasting, such material lasts a long time. However, the soundproofing effect of such coatings, unfortunately, is not able to completely protect against external noise stimuli.

Purchasing a wallpaper backing is often necessary in rooms with good audibility. This is especially true in apartment buildings. If you do not plan to cover the surfaces with plasterboard, such a finish will become indispensable.

Manufacturers promise a number of benefits using such wall coverings.:

1. Thermal insulation. You can insulate the walls well, get rid of fungus and prevent condensation.
2. Leveling surfaces. Although this material has a small thickness (about 5 cm), it perfectly masks any minor surface defects. This allows you to achieve good results when wallpapering.
3. Noise protection. The soundproofing of the material, although not completely, significantly reduces the level of extraneous sounds in the room.

However, the characteristics and reviews of such materials have different ratings among consumers. Why? Some note with indignation that this coating can completely fall off the wall. Others, on the contrary, praise this experience of insulating surfaces.

Due to the fact that there are many more positive reviews than negative ones, it can be assumed that the dissatisfaction of some is most likely caused by a violation of technology in the use of the material.

It is very important to choose the right glue for such canvases. You should not give preference to the usual wallpaper glue; PVA is ideal for polyethylene surfaces.

You can’t start wallpapering until the backing is completely dry, so it’s better to wait a few days. Roll wallpaper need to be glued on top with glue intended for this purpose. Moreover, overlap of the joints should be avoided, that is, the edge of the wallpaper sheet should be located in the center of the backing.

But in any case, before you start gluing surfaces with such materials yourself, it is important to carefully read the instructions. After all, strict adherence to all the instructions of the masters will allow you to properly finish the walls in the room.

So, with a wallpaper backing, everyone can independently create the perfect wall decoration; the surface will have a great look and make the room more comfortable and warm.

Wallpaper backing (video)

Many people prefer to install insulation under their wallpaper. When a person makes repairs in a house or apartment, he wants everything not only to be pleasing to the eye, but also to last a long time. In addition, it is necessary to take into account the various characteristics of the room in technical terms. Otherwise, it may turn out that the room turned out to be very beautiful, but cold and damp. Thermal insulation materials will help solve this problem.

At first glance, it seems that you won’t be able to install a thermal insulation layer in a room yourself, but in fact this is not at all the case. The main thing is to choose the right material and follow all recommendations.

By the way, internal insulation is not always to the detriment of the room’s dimensions. In other words, it is quite possible to do without various complex parts and structures, fiber or tile products.

There are many thermal insulation materials for walls. Conventionally, they can be divided into 2 categories: roll insulation for wallpaper (Polifom and other types) and plaster with thermal insulation properties.

Quite often, plasterboard sheets are used to insulate walls from the inside. This material is convenient to install. In addition, it not only insulates the walls, but also levels them. But in order to install drywall, you first need to make a special frame.

All reviews say that it takes up too much space. If the room is small in size, then this option is definitely not suitable.

Thermal insulating plaster can be applied independently if you already have experience in such work. Otherwise, it is best to trust the professionals. Many variants of such products have been developed.

Roll insulation is very popular.

There is a wide range of products in this category. In addition, installation is very simple and only involves a few steps. All roll-type products differ only in the adhesive substance used during installation. Drying time also differs.

What do you need to know?

The most common option for rolled thermal insulation materials is Poliform.

It is easiest to install such a heat-insulating layer. It includes several main phases:

1. Preparatory. First you need to remove the old layer of plaster from the wall. Then you need to eliminate small cracks by sealing them and removing irregularities. To do this, you can use plaster or foam.
2. Priming. Using a brush or roller, it is necessary to apply a primer-type mixture to the surface of the wall. Then wait until the layer is completely dry. Sometimes this procedure needs to be repeated.
3. Cutting insulation material. It is necessary to measure a certain piece on the roll. Be sure to leave a small gap. After this, cut the material into pieces.
4. Glue preparation and application. At this stage, it is very important to follow the instructions written on the glue package. It is very important to mix the substance thoroughly. When the glue is completely ready, apply it with a roller or brush to the walls. By the way, Poliform can also be self-adhesive.
5. Glue insulation. This process is practically no different from how to glue wallpaper. Be sure to smooth out the glued pieces of material and remove air bubbles.
6. Further seal all joints special masking tape.

After this, all that remains is to wait about 1-3 days (depending on the manufacturer and material). Then you can glue wallpaper or proceed to other types finishing works.

Types of heat-insulating plaster

Many people know how to apply plaster themselves. But if you don’t have such skills, then it’s best to trust a professional. Before you begin, you must select good plaster, which has thermal insulation properties.

It is imperative to know the classification of such products, the materials used, their quality, additional properties, and cost.

Nowadays there are several types of heat-insulating plaster on the construction products market. The materials differ in the composition of the filler, which has thermal insulation properties:

1. Wood sawdust. This filler is the cheapest. But you need to take into account that this material also has a low resistance to moisture, so it is better to choose another option for a dacha or balcony.
2. Expanded polystyrene. In other words, it is foam insulation. It is considered one of the most popular due to its high heat and sound insulation. But polystyrene foam insulation also has certain disadvantages. For example, this material can easily ignite. In addition, combustion produces toxic elements that are dangerous to people.
3. Vermiculite or perlite. These are mineral type fillers. Such a heat-insulating layer is almost ideal, since it has high rate fire resistance, resistance to biological and chemical factors. In addition, this material is also environmentally friendly. But such plaster also has disadvantages. If you use a perlite or vermiculite layer, then you must additionally install a vapor barrier coating, since the plaster will quickly absorb water.
4. Foam glass. This is another insulation for walls under wallpaper in the form of plaster. The material is waterproof. It is non-flammable and does not contain toxic substances. But its characteristic is such that despite its complete environmental friendliness and purity, the material still has a lower thermal insulating effect than that of the polystyrene foam layer.

It is imperative to pay attention to the fact that mineral-type plasters make the surface of the layer rough. Before gluing wallpaper on it, you also need to apply a final coating. As for the rest of the plasters, which are of the non-mineral type, such preliminary work will not be necessary.

Types of roll insulation for wallpaper

Roll insulation is now very popular. This is the easiest way to quickly and efficiently insulate an apartment, house or other premises with your own hands. By the way, the ancestor of this type of roll materials is pasting walls with ordinary old newspapers.

But now there are a large number of different new options on the construction products market. They differ in the basis used. Here are the popular varieties:

1. Expanded polystyrene thermal insulation. It has the same properties as plaster with this filler. Can be purchased in rolls. The substrate should be glued using an adhesive specially developed for this purpose. It can be replaced with an adhesive base for heavy wallpaper, but add a small amount of final plaster with a gypsum base to the composition. Despite the fact that companies producing such roll insulation for walls claim that the material adheres well, it is still not always possible to achieve the desired effect. To make the process easier, it is necessary to use polymer cement glue and a fiberglass mesh. But it is best to immediately purchase heat-insulating material that has a top layer in the form of cardboard.
2. Foamed polyethylene foam. This material is also called Polyphom. This roll substrate is very popular. Its structure is cellular with air bubbles. The material is covered with paper on both sides, so it looks very similar to regular wallpaper. Thanks to this trick, it is much easier to stick Polyf to the wall, and then fix the wallpaper on the material. The installation process is very simple, so anyone can do it themselves. In any case, you must follow certain rules. Before applying such a coating, it is necessary to carefully level the walls and remove all defects.
3. Thermal insulation with balsa wood. This option is completely environmentally friendly. In addition, it has good noise and heat insulation. This roll insulation is also quite neat and beautiful in appearance. Sometimes a cork-type substrate is used as the final finishing of walls. But this product is not resistant to water. Although you can also purchase special cork insulation, which is impregnated with a wax-based composition to repel moisture. This material can be used in rooms with high humidity. Another advantage is that the material does not absorb aromas. By the way, if you don’t want to level the walls before applying a heat-insulating layer, then this option is the most suitable. The cork backing completely hides all coating defects, so no preliminary leveling is required. If someone in the family has a tendency to an allergic reaction, then it is best to give preference to a cork layer. But there are also disadvantages. For example, for a rolled cork backing you will need special glue.
4. Wallpaper that has an additional layer for insulation. This is a completely finished product, which includes not only oilcloth wallpaper, but also spunbond, fibers and aluminum foil. This option is great for cases where the room does not require strong thermal insulation. Such wallpaper will help save money during renovations, but finding a suitable option with the required design is quite difficult.

When choosing insulation, it is best to focus on the technical characteristics of the material, its cost, and installation features. In addition, roll-type insulation also has additional functions. For example, thanks to them you can level the walls. They are also sound and vapor insulators. Another advantage is that wallpaper can be glued to such a coating several times.

Insulation for walls inside an apartment under wallpaper helps many families, so you shouldn’t skimp on it. It is best to purchase products that have good feedback. It is recommended to choose insulation from well-known manufacturers. As a rule, prices for such heat insulators depend on the brand and the product itself, and its properties. The cheapest option will cost approximately 900-1000 rubles per roll. As for cork-type heat insulators, their price varies from 900 to 6 thousand rubles. Polifoam can be purchased at a price of 1,200 rubles for a whole package. In this case, the width will be 50 cm, length 7 m, and thickness no more than 0.5 cm.

Wall insulation under wallpaper will prevent a person from freezing indoors even in cold winter or autumn, when the heating is not yet turned on. That is why it is very important to think through this point in advance at the stage of repair and finishing work in an apartment or house.

Before starting finishing work, you should decide on the thermal insulation option. The walls in a house or apartment can be insulated from the outside or the inside. External insulation tends to be much more expensive and is often unaffordable for those living on upper floors. In this case, thermal protection is performed from the room side. If necessary, save interior space by using insulation under the wallpaper.

Features of insulation of internal walls

In addition to thermal insulation, the walls in the apartment are insulated in order to achieve the following goals:

• isolate the room from the penetration of loud and unpleasant sounds;
• make the walls thicker;
• minimize the possibility of condensation appearing on the walls, as well as the development of harmful microorganisms and mold;
• level the surface of the ceiling or walls.

Advantages

Internal thermal insulation allows you to save up to 15% of heat energy, as well as increase the air temperature in the room by a couple of degrees. The issue of insulation becomes especially relevant during the off-season, when the heating is not yet turned on, but it is already cool outside. Cold will no longer emanate from the walls of a room treated with a heat insulator, including problem areas under the window sills.

The main advantages of this method of insulation are that the insulators used for this purpose are sold at a very affordable price, and their gluing does not require special practical skills or knowledge of the nuances of construction theory.

By installing thermal insulation material under the wallpaper, you can significantly save on construction activities such as primer or plaster. The insulation is capable of efficiently and effectively covering any defects and leveling out defects on the walls.

Modern industry offers consumers thermal insulators for wallpaper in the form of plaster or rolls, which you can easily glue yourself.

Plaster

Thermal insulating plaster looks like a mixture of sand, gypsum, lime and cement. Depending on the type of additives, it can be of the following types:

• with the addition of foam glass (has moderate thermal insulation properties, but protects well from fires and moisture);
• with foam granules (serves for effective insulation, but requires protection of walls from moisture);
• with wood shavings or sawdust (low cost, but highly absorbs moisture);
• with mineral additives: vermiculite or perlite (the material has low thermal conductivity, is resistant to temperatures and chemical compounds, but is capable of strong moisture absorption).

Installing plaster under wallpaper requires some experience, otherwise if the work technology is violated (incorrect mixing, incorrect installation on the walls), the wallpaper pasted on top simply will not stick.

Roll material

A more progressive and popular method is to insulate walls with roll insulation.
The standard substrate in the form of rolls has a thickness of 3 to 8 mm and the following dimensions: 14 m in length and 0.5 m in width. The main roll insulator can be polystyrene foam, cork or polyethylene foam.

A roll of expanded polystyrene insulation is considered a cheap material that reliably protects walls from harmful influences, provides high-quality insulation to the room and is capable of absorbing sounds. Its disadvantages include insufficiently good adhesion.

Polyethylene

More effective method Insulation of an apartment is considered to be the use of polyethylene foam, the most popular manufacturer of which is Poliform. Technical parameters of the material: thickness – 5 mm, thermal conductivity – 0.039 W/mK; noise absorption – 22 dB; tensile strength about 18 MPa; material density – 30 kg/m3.

Due to the fact that this wallpaper insulation is covered with a paper covering on both sides, it has excellent adhesion and adheres to the surface almost instantly. This insulation has affordable price(up to 1000 rubles per roll) and reliably protects the walls of the room. Designed for gluing any type of wallpaper, including heavy vinyl.

Also in demand is the insulator Polizol, which has similar technical characteristics.

The traffic jam is considered the best option for insulation of apartments. Its main advantages are lightness, aesthetics and naturalness of the material. Quite often, cork is used as a finishing decoration for walls; it is not necessary to glue wallpaper on top.

For rooms with a high degree of humidity, cork insulation material impregnated with wax, produced by Ibercork, is intended. This cork, sold in rolls of 5 m2 or more, has a large selection of textures, and one side is necessarily saturated with glue, which makes installation easier and more convenient.

The disadvantage of this type of material is that the price is not affordable for everyone: about 500 rubles. per m2.

Installation

First, the walls are cleaned of old building materials, if necessary, they are leveled and coated with a primer. If there are differences on the wall of more than 5 mm, they are covered with plaster.

General requirements when using any type of insulation: air humidity no more than 70%, room temperature no less than -10 °C and complete absence of drafts. Sometimes surfaces require additional treatment to increase adhesion. Before gluing the entire volume of wallpaper, you need to check its adhesion to the insulation by making a test cut in an inconspicuous place.

Gluing roll insulation

The materials are rolled out and cut into the required sizes. An adhesive base is applied to the layer, left for 5 minutes and the insulation is attached to the wall. The canvases must be glued end-to-end, only vertically and from top to bottom. The joints are pressed with a roller and sealed with masking tape.

Important! You can glue wallpaper onto the treated surface only after 72 hours!

Thermal insulating plaster

After cleaning and priming, beacons are distributed on the surface. The mixture, stirred with a construction mixer, is applied to the wall in a layer no thicker than 3 cm. The next layer can be applied only after the previous one has completely dried.

At the end of the work, the beacons are removed from the walls, the holes from them are covered with the same plaster, after which the wall is thoroughly cleaned. The thermal insulation properties of the plaster manifest themselves approximately 2 months after it dries.

The main thing when installing insulation under wallpaper is to strictly follow the instructions indicated on the material label.

If the heat in your house does not stay warm in winter, and the reason for this is the walls are too thin or lack insulation, then insulation for the walls from the inside under the wallpaper will help solve this problem. Its use significantly reduces heat loss and increases the level of comfort in the room.

This is the most optimal way of internal insulation when you want to maintain the volume of the room. After all, all the others, which involve the construction of a frame and the use of slab or fibrous thermal insulation materials, force us to accept the fact that the area of ​​the room will become significantly smaller due to their thickness.

Types of insulation for wallpaper

Strictly speaking, there are two main types of insulation intended for wallpapering. This is heat-insulating plaster and roll insulation for walls under wallpaper.

Although the same drywall also performs thermal insulation functions and serves as an excellent basis for subsequent decorative finishing. But to install it, you need to construct a frame that “eats up” the usable area, so we won’t talk about it.

Thermal insulation plaster

It happens different types depending on the filler included in its composition, which determines the heat and sound insulation properties of the plaster, as well as its flammability, vapor permeability and other performance characteristics.

• Cork backing. Natural, environmentally friendly pure material, considered one of the best insulation materials not only for walls, but also for other structures (see also article). Can be used as a finishing touch. Insulated cork wallpaper with wax impregnation is used for finishing walls in damp rooms.

Cork insulation is available both in rolls and in the form of slabs 3-5 mm thick

• Ready-made wallpaper for wall insulation. They are a multilayer self-adhesive material made of aluminum foil, non-woven fiber, spunbond and oilcloth wallpaper.

In addition to the fact that the described materials serve for thermal insulation, they perform several other important functions. These include sound and vapor barrier, as well as wall leveling. Of course, they won’t mask large potholes and cracks, but they will hide small irregularities perfectly.

The advantages of roll insulation include the fact that wallpaper can be glued to it many times.

Installation of roll insulation

Regardless of the type of insulation, it is installed in the same way in all cases.

Only the adhesive compositions and their drying time differ.

1. Remove all old finishes from the walls, seal cracks and potholes with foam or plaster mixture.
2. Prime the surface.
3. Cut the roll insulation into pieces of the required length.
4. Prepare the glue as required by the instructions and apply it to the wall.
5. Glue the insulation, smoothing it from top to bottom and to the sides, like regular wallpaper. Adjacent strips are glued end to end.

1. Tape the seams with masking tape or paper tape.

The glued insulation should be allowed to dry for 24-72 hours (in accordance with the manufacturer's recommendations). After which you can begin decorative finishing.

Conclusion

Thermal insulation backing for wallpaper allows you to create a cozy atmosphere and comfortable temperature in your apartment. The price of this insulation method is significantly lower, and the speed of implementation is higher than when using standard methods with constructing a frame, filling it with traditional thermal insulation materials and cladding.

In the video presented in this article you will find additional information on this topic.

Just recently, it was difficult to imagine that something other than newspapers would be used as a preparatory layer for wallpaper. Probably, when carrying out repairs, you yourself used them more than once. Already today you can find innovative materials on sale that allow you not only to level the surface, but also to achieve an insulation effect.

“Polifom” for wallpaper, reviews of which you can read in the article, is a modern backing made from On both sides during the production process, the material is covered with thick paper. Its structure is quite voluminous and soft, so it can be used to hide surface defects and give them sound and heat insulating properties.

Reviews about the substrate "Polifom"

“Polifom” for wallpaper, reviews of which are recommended to be read before purchasing the product, is a layer that increases the adhesive properties of the base surface and decorative covering. Not so long ago, it was common to use old newspapers as substrates. However, they can shine through a thin coating, and they cannot be used to level the walls. Newspapers in this capacity are a thing of the past also for the reason that they do not allow achieving a heat-insulating effect.

Already today on the market you can find dense vinyl sheets that eliminate the need for leveling. Today it serves as sound and heat insulation functions. “Polifom” for wallpaper, reviews of which are useful to read before visiting the store, is a material that, according to consumers, performs many functions.

The right to use this trade name belongs to Polifoam Ltd Co, which operates its labor activity in Hungary. Today, Polifom is the only material in Europe that has 9001. This, as users emphasize, is sometimes decisive when choosing.

Reviews about production features

“Polifom” for wallpaper, reviews of which you can read in the article, is foamed during the manufacturing process by adding chemicals. As the material cools, it turns into a mass of air bubbles. As buyers emphasize, they do not contact each other and represent a closed cellular structure. Consumers like that such a structure guarantees low thermal conductivity.

The resistivity of the finished material increases, which is due to the technology of cross-linking polyethylene. The material gains the ability to withstand the effects of chemicals. "Polifom" can be used when exposed to direct sun rays and temperature changes. If you need insulation for indoor walls, then you may prefer “Polif”, which is laminated on both sides with white paper; it is, as it were, welded to the structure, so it is not possible to tear it when the material deforms.

Feedback on operational features

According to consumers, Polifom is quite easy to stick on. The process is similar to installing heavy vinyl wallpaper. Such work makes it possible to achieve excellent internal thermal insulation and help eliminate dampness, as well as form a soundproofing layer and hide small irregularities.

Buyers especially emphasize that the layer thickness is only 5 mm. The material is sold in convenient packaging in the form of rolls, the dimensions of which are 0.5x14 m. The density of the material is equivalent to 30 kg/m 2.

Specifications

If you want to purchase insulation for indoor walls, you may prefer the described substrate. It has insignificant thickness and weight, and has excellent technical characteristics. The material can even be used as an independent insulation material, as well as in tandem with other thermal insulation. Before purchasing, you should familiarize yourself with the technical characteristics, among them thermal conductivity should be highlighted, it is 0.037 W/(m*K). This indicator is relevant for temperatures of +10 °C. In terms of the level of thermal insulation, one layer of Polyfoma can be equated to half a brick.

Before you renovate a room, you should take care of soundproofing. If you use Polifom, it will be able to reduce the impact noise level by 22 dB. This will eliminate extraneous noise and sounds. The material absorbs acoustic and impact noise. This insulation is also good because it does not absorb moisture, which is due to the closed cellular structure. Does not pass through the layer and water vapor. If you look at fire safety standards, you can note that “Polifom” belongs to the G2 flammability class, which indicates that the material burns and ignites quite easily.

additional characteristics

The described insulation for wallpaper has outstanding technical characteristics, among them resistance to deformation and tearing should be highlighted. The base of the material is chemically cross-linked, which allows it to restore its previous shape. equivalent to 0.5 MPa, this is true at a pressure equal to 2000 N/m 2.

Some consumers are also interested in chemical resistance. In the described case, it can be noted that the material does not react with many chemicals; it is compatible with substances that are most often used in construction, namely:

• cement;
• wood;
• concrete;
• glue;
• solvent;
• acetone.

“Polifom” is biologically stable, it does not rot and is not covered by fungus and mold. Polymer raw materials are not an attractive environment for rodents and insects. This wallpaper insulation has a fairly wide operating temperature range, which varies from -60 to +90 °C. It is at this limit that the material can be used.

It does not contain chemicals that could release toxic volatile compounds. This speaks of environmental friendliness. Another advantage of Polyfom is the possibility of its long-term operation. It can be used for up to 50 years, while it remains suitable for repeated wallpapering.

Additional uses

Polyfom wallpaper backing is used in industry due to its outstanding mechanical characteristics. The material exhibits resistance to mechanical stress during operation. It can have different levels of density, which varies from 30 to 180 kg/m2. This makes it possible to use the substrate in shipbuilding, mechanical engineering and aircraft manufacturing. Quite often, such a substrate is used when installing air conditioning systems.

Why choose Polifom

If you have to make repairs in a cold and damp room, then its decorative finishing will imply the need to use insulation under finishing material. If we are talking about “Polyfom”, then it will be able to reduce the coefficient of vapor permeability and heat transfer.

The material does not form condensation, which indicates that there will be no dampness in the room. Such a substrate is simply necessary for corner apartments in which the capabilities of the heating system are limited. The underlay is perfect for those rooms whose walls are in contact with the staircase. From the latter, cold and noise come inside.

"Polifom", the price of which is 1500 rubles. per roll, covered on both sides with thick paper. Before purchasing, it is recommended to inspect the material; the protective layer should have an even white color, there should be no roughness, drips or stains on it. It is recommended to try to peel the corner of the paper from the base. If this was achieved without difficulty, then the material cannot be called high quality. In some cases this may happen if storage conditions are not followed.

"Polifom", the price of which is quite reasonable, should not have a smell. If you have high-quality thermal insulation in front of you, then it should be elastic, resilient and dense. You can try to tear it, if this happens, then the material is of low quality.

Installation instructions

It is quite simple to stick “Polif” on the walls; even a beginner can cope with this work. The main requirement is to follow the instructions. First you need to prepare the base surface. To do this, dirt, old wallpaper and peeling plaster are removed from the walls. If there are bumps and depressions on the wall, then they need to be leveled and covered with putty. Before making repairs in a room, the surface must be primed with a deep penetration compound, this will increase the adhesive properties of the surface.

Next, you should prepare the Polyfoma canvases by first taking measurements and cutting the material into separate pieces. “Polyfom”, the gluing instructions for which are described in the article, must be laid on PVA glue. However, you can use any other composition that is intended for vinyl and non-woven wallpaper.

If the room is operated under conditions of high humidity, then liquid nails or baguette glue should be prepared. The composition is applied to the canvas and left in this state for up to 10 minutes. Next, “Polif” should be applied and pressed against the wall, smoothing its surface with a special spatula, moving the tool in different directions.

Work methodology

The next strip should be glued butt to the previous one. The seams need to be glued; this will provide increased strength to the coating. The substrate is left until it dries; you can start wallpapering the walls after 72 hours. Exactly how much will be enough for the glue to dry completely. For wallpaper, you can use the same mixture on which Polifom was laid.
