Insulated wallpaper. What wall insulation to use for wallpaper. Overview of insulation for walls under wallpaper

If during the heating season the temperature in the rooms is kept at +18 to 22 °C, then it is necessary to eliminate heat leakage through thin walls. This is done in two ways: by insulation from the outside or from the inside. The second method is resorted to if the temperature outside has dropped to +5 ° C. For this, it is not necessary to lose the area of \u200b\u200bthe internal space, since there is a thin insulation under the wallpaper.

Its installation is easily carried out by 1-2 people. This method of internal insulation allows you to save up to 15% of energy and increase the temperature in the room by 2-3 °C. According to reviews, insulation under wallpaper is twice as effective as wall carpets that have long gone out of fashion. It creates a feeling of coziness and comfort due to the fact that the walls, especially under the window sills, no longer radiate cold.

Types, their advantages and disadvantages

1. Rolled insulation for wallpapering protects not only from the cold, but also from noise, it is easy to use at home, almost the same as wallpaper. It can be made from:

expanded polystyrene;
foamed polyethylene foam;
corks (may also be produced in the form of plates).

2. Heat-insulating plaster is a cement-sand mixture with the inclusion of porous particles: sawdust, expanded polystyrene, perlite, foam glass. However, this insulation can be laid under the wallpaper only as an additional material, since its insulating properties are inferior to the previous type. In addition, it requires experience with it, because if you break the technology of mixing or laying it, the wallpaper simply will not stick to the wall.

Overview of insulation for walls under wallpaper

The parameters of manufactured products for home use are approximately the same: 0.5x14 m, they differ only in thickness, which can be 3, 4, 5 or 8 mm. For those for whom sound insulation is especially important, you should pay attention to the foam polyethylene foam backing. The most famous manufacturer that produces it is Poliform. The technical characteristics of this thin insulation under the wallpaper are impressive:

density - 30 kg / m3;
noise reduction level - 22 dB;
tensile strength - 18 MPa;
thermal conductivity - 0.039 W / mK.

Another feature is the extraordinary ease of installation, as it is pasted over with paper on both sides. This ensures very high quality adhesion to the wall surface. You can buy Poliform for wallpaper from 880 rubles per roll, in which there are 14 linear meters or 7 m2. The EcoHeat manufacturer is of good quality. Its parameters are the same as the previous brand. It is also not susceptible to moisture, fungi, bacteria, it is pasted over with paper that is inseparable from the base, only it is exclusively white. The cost of the substrate under the wallpaper of this company is 900-1000 rubles.

Polyzol can be put on a par with previous brands. In terms of technical characteristics, it is in no way inferior to Poliform. The description of the insulation intended for wallpapering includes the manufacturer's distinctive offer - sheets with a thickness of 8 mm. They protect against noise and cold by 30% better, and also allow you to level the walls without installing a frame.

Ibercork cork insulation belongs to a separate category. It is environmentally friendly because it is natural. It is lightweight and durable, has good thermal insulation and protects against loud sounds. The cork backing does not have to be closed - it looks quite aesthetically pleasing. The manufacturer offers a wide range of textures in a range of traditional colors. The price of cork insulation for wallpaper for 10 m2 ranges from 850 to 3,000 rubles.

How to choose

If there is no experience in repair work, then it is better to buy heaters with a paper surface for home use: wallpaper will be easier to glue to them, and they themselves will hold well.

If tenants are prone to allergies, cork should be preferred.

Under the wallpaper, sticking a thin foam insulation is much easier than a wide one, but it is better to give it preference in cases where the walls do not need to be leveled, the heat leakage is not significant and the neighbors are not very noisy. It is also worth considering the color of the wallpaper when choosing a substrate: if they are light, pastel, then you need to buy white insulation. And, conversely, under dark sheets, you can take materials of any color, by the way, saving money. When the gray insulation is located under the light-colored wallpaper, it gives them a dirty shade.

How to properly insulate an apartment with your own hands

In order to securely attach the material to the wall, the surface must be prepared: cleaned of old wallpaper, falling off pieces of plaster. All cracks and irregularities resulting from this procedure must be eliminated with putty. To protect the walls from mold, apply a primer to them and wait for it to dry completely. Further, the technology for gluing insulation is carried out according to the same scheme as for wallpaper:

in accordance with the instructions on the package, glue is prepared for heavy wallpaper (for cork and wide sheets - with the addition of gypsum putty);
rolled out on the floor, measured and cut insulating material;
glue is applied to the wall and prepared sheets;
until it is dry, the strips are carefully applied to the surface strictly vertically (you can check with a plumb line) and pressed with a dry roller.

Thus, the roll insulation under the wallpaper is glued over the entire surface. It is important to ensure that no gaps are accidentally formed between the sheets during the work. To do this, it is better to put them a little on top of each other. Excess sections are cut off with a paint knife. Usually such moments occur if the walls are not quite even. After completion of work, it is necessary to allow the insulation to dry completely. After 72 hours, you can start wallpapering.

Many people prefer to lay insulation under the 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 serve for 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. Heat-insulating materials will help to solve this problem.

At first glance, it seems that it will not be possible to install a thermal insulation layer in the room on your own, but in fact this is not at all the case. The main thing is to choose the right material and follow all the recommendations.

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

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

Quite often, plasterboard sheets are used to insulate walls from the inside. This material is easy to install. In addition, it not only insulates the walls, but also levels them. But in order to mount 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.

Heat-insulating plaster can be applied independently if you already have experience in such work. Otherwise, it is best to trust 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 involves only a few steps. All roll-type products differ only in the adhesive used during installation. The drying time is also different.

What do you need to know?

The most common version of rolled thermal insulation materials is Poliform.

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

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

After that, it remains only to wait about 1-3 days (depending on the manufacturer and material). Then you can glue the wallpaper or proceed to other types of finishing work.

Types of heat-insulating plaster

Many people know how to apply plaster on their own. But if there are no such skills, then it is best to trust a professional. Before starting work, it is necessary to choose a good plaster, which has a thermal insulation property.

Be sure to know the classification of such products, the materials used, their quality, additional properties, cost.

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

sawdust. This filler is the cheapest. But it must be borne in mind that such material also has a low resistance to moisture, so it is better to choose another option for a summer residence or a balcony.
Styrofoam. In other words, it is a 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, during combustion, toxic elements are produced that are dangerous to humans.
Vermiculite or perlite. These are mineral fillers. Such a heat-insulating layer is practically ideal, since it has a high 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, as the plaster will quickly absorb water.
Foam glass. This is another wall insulation for wallpaper in the form of plaster. The material is waterproof. It is non-flammable and contains no toxic substances. But its characteristic is such that, despite its complete environmental friendliness and cleanliness, the material still has a lower rate of heat-insulating effect than that of the polystyrene foam layer.

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

Varieties of roll insulation for wallpaper

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

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

Styrofoam thermal insulation. It has the same properties as plaster with this filler. You can buy 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 is glued well, it still does not always work out to achieve the desired effect. To make the process easier, it is necessary to use polymer cement glue and fiberglass mesh. But it is best to immediately purchase a heat-insulating material that has a top layer in the form of cardboard.
Polyethylene foam type. This material is also called Polyph. Such a roll substrate is very popular. Its structure is cellular with air bubbles. Both sides of the material are covered with paper, so it is very similar to ordinary wallpaper. Thanks to this trick, sticking Polyf is much easier to the wall, and then fixing the wallpaper on the material. The installation process is very simple, so anyone can handle it on their own. In any case, certain rules must be followed. Before applying such a coating, it is necessary to carefully align the walls and remove all defects.
Thermal insulation with cork wood. This option is completely eco-friendly. In addition, it has good sound and heat insulation performance. This roll insulation is also outwardly quite neat and beautiful. Sometimes a cork-type substrate is used as a final wall finish. But this product is not water resistant. Although you can also purchase a special cork insulation, which is impregnated with a wax-based compound to repel moisture. Such material can be used in rooms with a high indicator of humidity. Another advantage is that the material does not absorb odors. By the way, if there is no desire to level the walls before applying a heat-insulating layer, then this option is the most suitable. The cork backing completely hides all defects in the coating, so there is no need for pre-levelling. If someone in the family has a tendency to an allergic reaction, then it is best to give preference to the cork layer. But there are also disadvantages. For example, for a rolled cork substrate, you will need a special glue.
Wallpaper, which have an additional layer for insulation. This is a completely finished product, which includes not only oilcloth-type wallpaper, but also spunbond, fibers and aluminum foil. This option is great for those cases where strong thermal insulation is not required in the room. Such wallpapers will help save money during repairs, but finding a suitable option with the necessary design is quite difficult.

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

Insulation for walls inside an apartment under wallpaper helps many families, so you should not save on it. It is best to purchase products that have good reviews. It is recommended to choose heaters from well-known manufacturers. As a rule, the prices for such heat insulators depend on the brand and the product itself, its properties. The cheapest option will cost about 900-1000 rubles per roll. As for cork-type heat insulators, their price varies from 900 to 6 thousand rubles. Polyfoam (Polifoam) can be purchased at a price of 1200 rubles for the 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 the wallpaper will not allow a person to freeze indoors even in cold winter or autumn, when the heating is not yet turned on. That is why it is very important to think over this point in advance even at the stage of repair and finishing work in an apartment or house.

Along with rising energy prices, the issue of thermal insulation of housing is becoming increasingly relevant. Manufacturers of building materials introduce new technologies and offer non-standard solutions. One of these methods is insulating wallpaper. The material can be used as a finishing wall covering or act as a substrate for decorative cladding.

Characteristics of polystyrene foam wallpaper: pros and cons

To date, wallpaper made of expanded polystyrene is used quite rarely. The innovative material is used as an insulating substrate for decorative wall decoration or as a topcoat with thermal insulation properties. The composition of the insulated wallpaper: polystyrene foam and a paper layer on the outside.

Characteristics of a roll heat insulator:

density - 200-300 g / sq.m;
web thickness - 3-10 mm;
roll length - 10-15 m;
width - 0.5-1 m.

The main advantages of styrofoam wallpaper:

thermal insulation ability. An important quality of the polystyrene foam substrate is the preservation of heat in the room. The effect of using a 6 mm thick insulation roll is comparable to using a 12.5 cm brick barrier.
Noise reduction. The level of sound impact from the street or neighbors is significantly reduced - depending on the thickness of the insulating substrate, the noise effect can be reduced within 21 dB.
Leveling effect. Preliminary wall cladding with thermal wallpaper will hide minor surface defects.
Environmental friendliness. The material does not contain freon, butane and does not emit harmful volatile components into the atmosphere during operation. An additional plus is non-susceptibility to rodents and insects.
Availability. Thermal insulation of walls with wallpaper will not be expensive, and the money spent will pay off with noticeable savings on heating.

The rolled insulation is easy to install, the expanded polystyrene sheets “lay” evenly on the walls and are easily joined together, forming a tear-resistant structure. However, this method of thermal insulation is not without its drawbacks.

Cons of styrofoam wallpaper:

Possibility of condensate accumulation. As with any method of internal thermal insulation, a thermal wallpaper sticker shifts the dew point in the direction of the room. This causes condensation to accumulate between the insulation layer and the wall. To avoid freezing, it is desirable to provide additional external thermal insulation of the building and high-quality ventilation of the room.
Flammability. The expanded polystyrene substrate is combustible. However, the degree of flammability and smoke formation depends on the qualitative composition of the material and the presence of flame retardant impregnation. Some manufacturers try to minimize the level of fire risk by releasing a self-extinguishing product.

The nuances of choosing a wall roll insulation

The construction market offers several types of thermal insulation substrate. The most in demand: polystyrene foam, polyethylene and cork materials.

Distinctive features of each type:

Cork insulation raises the temperature in the house by 2-3°C in winter, and in summer it helps to keep the room cool. Disadvantages of natural insulation: high cost and the need to use special glue.

It is permissible to repeatedly apply wallpaper on roll insulation while maintaining the declared properties of the heat insulator. Substrates with paper lamination hold well on the walls, foil products reflect heat better.

Advice. High-quality insulation - elastic, elastic and dense. Before buying, the substrate must be probed and assessed for rupture - if the material is easily torn, then it is not worth buying. Safe thermal wallpaper should not have a strong odor

When buying a substrate, you must consider the color of the decorative wallpaper. Under light colors, it is better to choose a white insulation - the optimal basis for wallpaper of any color.

Before choosing wallpaper from expanded polystyrene, it is necessary to evaluate the required degree of thermal insulation. Thermal wallpaper with a thickness of 3-5 mm is sufficient for finishing adjacent walls. Thicker material will provide better noise reduction and better insulation.

The technology of wall decoration with heat-insulating wallpaper

The order of installation of thermal wallpaper implies mandatory preparation, priming of the walls, the choice of a suitable adhesive composition and adherence to the method of gluing the insulation.

Necessary materials and inventory

To perform finishing work you will need:

insulating underlay;
glue - a composition designed to work with heavy wallpaper is suitable; when calculating the quantity, it must be taken into account that the glue will be applied twice - on the surface to be glued and on the wallpaper;
putty for leveling the wall - the composition is selected in accordance with the type of base;
deep penetration soil that prevents the appearance of mold;
spatulas of different sizes;
tape for finishing the joints of thermal wallpaper sheets;
pressure roller with a low pile;
construction knife;
measuring instruments (tape measure, level);
soft cloth;
glue roller.

If you need to remove old wallpaper, you can use a sharp knife or scraper.

Surface preparation

Preparatory activities can be divided into several component stages.

Stage 1. Removing the old finish:

Moisten the surface and leave for 15-30 minutes.
Pry off the soaked wallpaper with a sharp tool and remove it from the wall.
If the measures taken were not effective, it is necessary to use a special wash.

Stage 2. Elimination of defects. Apply putty to the surface with a wide spatula, smooth with a trowel. After the layer has dried, the wall must be sanded and dust-free. Apply the primer evenly in one or two coats (depending on the porosity and friability of the substrate).

Follow-up actions should be started after two or three days, provided that the primer is completely dry. Optimal conditions for further work:

temperature - from +10°С;
humidity - within 70 °.

Bonding of the thermal underlay

Before proceeding with the installation of thermal wallpaper, they must be prepared:

Measure the height of the room.
Spread the insulation on the floor and mark the cut points. At the same time, it is necessary to leave a margin of 2 cm for the final trimming after gluing the wallpaper to the wall - under the ceiling and floor plinth. For the arrangement of acoustic and thermal insulation, the “wall-floor” laying method is used - the substrate strips are placed on the wall with an overlap of 15 cm. Subsequently, the finishing floor covering is mounted. This method reduces the likelihood of cold spots.
After cutting, leave the insulation sheets to lie down and straighten up under their own weight.

Pasting technology:

Mix the adhesive solution, observing the proportions recommended by the manufacturer.
Apply glue to the inner surface of the strip, leave for 5-15 minutes for impregnation (the exact period is indicated on the package of thermal insulation wallpaper).
Treat the wall, capturing an area wider than the size of the panel.
Attach the insulation to the wall, smooth it out with a soft roller or plastic spatula in the direction from top to bottom. Remove excess glue with a soft sponge.
Check the verticality of the first strip with a level - the rest of the elements will be placed along it.
The second canvas is joined closely with the first cut, avoiding the appearance of bumps.
The polystyrene foam substrate cannot be bent at the corners - the wallpaper is joined end-to-end. The gaps that appear must be filled with sealant.
Joint lines should be covered with adhesive tape or masking tape.

Finishing decorative finish

When choosing wallpaper to cover the insulated substrate, preference should be given to extremely dense options. Thin paper products will not work, as over time the joints may disperse.

Procedure:

Cut out the wallpaper with a margin for cutting.
According to the level or plumb line, “beat off” the vertical line - for an even location of the first strip.
Apply glue to the wallpaper and the wall.
Apply the first canvas to the surface, leveling it over the entire area and “expelling” the air.
Cut off excess wallpaper, aligning the top and bottom of the junction line with the wall and floor.

Overview of popular manufacturers

A wide range of thermal substrates indicates the demand for the material. Among consumers, foreign and domestic brands have proven themselves well: Thermo-Tab, Eco-Tap, Eco-Heat, Globex, Polyfom.

Thermo tab. Insulated wallpaper by Izopan (Ukraine) is produced with a thickness of 3 mm, 5 mm and 6 mm. The basis of the material is polystyrene. The material is neutral - does not undergo decomposition by microorganisms and does not emit harmful substances.

Thermo-Tab insulation is suitable for use in commercial and residential premises. Estimated cost - about $ 9 / roll 6 mm thick.

Eco tap. The heat-insulating substrate for wallpaper is available in 3 or 6 mm thickness. The basis of the material is expanded polystyrene. Eco-Tap basic features on 6mm:

density - 20 kg/cu.m.;
average thermal conductivity class - 0.06-0.115 W / m * s (1 mm of the substrate corresponds to 20 mm of brick, 10 mm of foam concrete or 40 mm of reinforced concrete wall);
roll length - 10 m, width - 50 cm;
estimated cost - 3.5 USD/roll.

In addition to manufacturers of expanded polystyrene wallpapers, polyethylene substrates are in demand:

Ecohit. Both sides of the polyethylene foam sheet are coated with white paper. The material is popular due to a number of undeniable advantages:
- strong homogeneous structure;
- versatility - applicable to wallpaper of any color;
- increased level of moisture resistance;
- neutrality to solvents;
- the presence of antifungal impregnation;
- thermal conductivity within 0.031-0.033 W / m * K;
- almost zero vapor permeability;
- it is possible to use conventional PVA glue for gluing;
- service life - about 50 years.
Polyph. Representative of the ECO segment, produced with a thickness of 4-8 mm. The material is certified according to the integrated system ISO 9001. The main characteristics of a 5 mm thick web:
- degree of thermal conductivity - 0.043 W / m * K;
- weight of thermal wallpaper - 230 g / sq.m;
- density - 30 kg / cubic meter;
- combustibility category - G4 (highly flammable material);
- the insulation reduces the cold radiation of the walls, prevents the appearance / spread of mold and does not absorb moisture.

An alternative solution to the "weeping walls" is gluing Penolon (analogous to Polyfoma). Wallpaper is resistant to alcohol, alkalis, gasoline and other aggressive substances. The chemically cross-linked polymer is characterized by minimal deformation and low thermal conductivity.

Of course, the interior wall cladding with the use of heat-insulating wallpaper will give the desired effect and increase the energy efficiency of the house. However, to achieve a more tangible result, it is necessary to act comprehensively and additionally insulate the building from the outside.

To keep the heat inside the room and increase the sound insulation of the walls, use roll insulation for wallpaper.

Eat several types this building material. They are based on polyethylene foam or cork wood substrate.

Like every insulation, roll insulators have advantages and disadvantages, their own characteristics and application features. There are also a number positive general properties, which must be considered when choosing a heater for wallpaper:

high-quality and relatively inexpensive insulation of the room from the inside, allows you to save thermal energy and raise the temperature by 2-3 ° C;
simple preparatory work;
easy installation of building material on the walls, which allows you to do all the work yourself;
soundproofing and noise-absorbing properties;
long service life and the possibility of sticking new wallpaper after removing the old one.

The main technical characteristics of roll insulation

A worthy representative of the group of heaters for wallpaper made of foamed polyethylene is roll polyfoam insulation.

Manufacturer - Hungarian company Polifoam Ltd Co, which has an ISO 9001 certificate, which indicates the reliability of the supplier in the market and the compliance of its products with the requirements of standards.

Insulation under the wallpaper produced using a technology that increases the resistance of the material to chemicals, sudden changes in temperature and ultraviolet rays.

From two sides polyethylene foam laminated thick white paper, when pasted on which the wallpaper does not change its gamut and tone. The connection of these layers in the insulation is very strong, it cannot be destroyed, even when trying to break it with Polyf.

Due to the fact that the manufacturer complied with all requirements on environmental safety, it is allowed to use this roll insulation not only in residential buildings, but also for the insulation of industrial premises.

A standard polyethylene foam roll has a length of 14 m and a width of 0.5 m, with a material thickness of 4 mm to 8 mm, as well as specifications:

The thermal conductivity of Polyfom is 0.037 W/m·K, which corresponds to the index of laying in half a brick.
Resistance to deformation is based on the fact that the elastic modulus of the material is 0.5 MPa at a pressure of 2000 N/m 2 .
The temperature limits at which this insulation is used for wallpaper are from -60 to + 90 ° C.
This building material does not have a chemical reaction to cement and concrete, various building adhesives, acetone. It is neutral with respect to many chemicals.
It is not exposed to infection by fungi and various types of mold. Not attractive to rodents and insects.
Reduces impact noise by 22 dB.
Does not emit harmful or toxic volatile substances.
It has a long service life (up to 50 years), without changing the technical characteristics.

Attention! The disadvantages of roll insulation made of polyethylene foam include poor fire resistance. According to the classification, they have a G2 flammability, that is, they can quickly ignite.

In contrast to the insulation under the wallpaper made of polyethylene cork insulation made from natural raw materials and has the following parameters:

thermal conductivity coefficient of the material - 0.04 W / m K;
substance density 100-130 kg/m 3 ;
combustibility class - G3 (material is normally combustible);
the thickness of the cork layer in the insulation is 10 mm.

Roll cork insulation environmentally friendly and completely safe for humans and pets.

At high humidity in the room does not grow moldy and is not a medium for distribution all kinds of fungi. Durable.

It is allowed to use cork insulation in certain interiors for wall decoration, without additional wallpapering.

How to glue roll insulation under wallpaper?

When placed on the walls of various heaters, construction work is carried out in stages, and have minor differences:

regardless of the type of installed roll insulation under the wallpaper, old wallpaper is removed, the walls are cleaned of dust and dirt;
the surface is leveled by applying plaster followed by a primer (for cork heaters, a deep penetration primer is used);
sealing individual cracks and dents with a special composition of a mixture of gypsum and chalk, which are easy to buy in hardware stores or cook on your own;
according to the recommendations of the manufacturers, glue is diluted, which is suitable for a particular of the above heaters;
cut the roll material in accordance with the size of the room;
when using Polyfoma, the insulation itself is covered with glue;
if cork material is used, then both it and the wall surface are covered with glue, and then the installation is carried out;
glue any rolled insulation always end-to-end.

Roll insulation for wallpaper greatly simplify repair and construction work on insulation and noise insulation of various types of premises. The price of these types of building materials is quite affordable. Separately, we can mention the relatively high cost of cork insulation, but their quality is unrivaled, so they are in high demand.

Many people think that if the question arose of finishing and decorating the wall during repairs, it is enough just to choose the wallpaper you like. However, in addition to this, noise insulation, thermal insulation, as well as the condition of the surfaces are important conditions. Therefore, special soundproof wallpapers have been created to improve living conditions in the house (prevent the negative effects of external stimuli), which will become simply indispensable helpers in repairs.

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

The main advantages of such a coating for surfaces are sound insulation, as well as thermal insulation.

In addition, this material is well suited for any type of wallpaper. That is, such material will allow you to quickly and efficiently decorate the walls.

Key Benefits:

It is characterized by its high strength, you can not worry that it will tear easily.
Thanks to the use of environmentally friendly materials for the production, it is perfect for any home.
Such a special surface does not absorb moisture, but rather helps to prevent condensation.
Noise isolation of these wallpapers helps to achieve comfort and a calm environment.

Such a rolled surface is an excellent material on which the selected wallpaper is pasted. Moreover, manufacturers of such substrates have achieved excellent production results. This surface does not lose its properties for many years, which allows several times to paste over the walls with wallpaper.

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

The main producers today are:

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

Characteristics and reviews of the masters

All masters involved in finishing and decorating walls very carefully choose materials for repair. This is not surprising, because the duration of use of the wall covering depends on the quality of the materials.

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

Such coatings are not suitable for rooms with high humidity.
Be sure to treat the surface of the wall, if present, even the slightest manifestation of the fungus.
Too thin wallpaper density can show through the hidden substrate, so it is better to choose a denser material for pasting walls.
Underlayment under the wallpaper cannot completely soundproof the room. Even the most expensive types are not able to guarantee this. However, due to its reasonable cost, it is possible to achieve a good result, and sound insulation will become possible.
The material is very easy to use, cuts well and thanks to the paper surface the sheet can be easily glued.
The substrate differs in the ecological safety, has no smells, and does not emit dust. That is, it can be used for wall decoration in any room.
Such coatings received excellent reviews due to their ability to increase heat-shielding properties. Therefore, such a heater is indispensable for wall decoration in block houses and cottages.

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

Due to the ease of use of this material, it is possible to quickly achieve excellent results. And you don't have to be a professional to do it.

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 with high quality? Before using the wall underlay, the surface must be prepared. Old wallpaper should be removed, and the walls should be cleaned of paint. With the help of a special putty, cracks and cracks are leveled. 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 align it. The substrate should be cut to the desired dimensions and placed under the press. After that, the inner smooth surface of the canvas is coated with special glue. Glue is selected suitable for polystyrene, PVA or designed for heavy wallpaper. The whole process is similar to the usual pasting of rolled sheets, however, the sheets are glued end-to-end.

When processing the surface of the substrate, do not apply glue to the joints, this leads to the material sticking together and after drying, the seam may become uneven. It is important to ensure that there are no voids. To get rid of emerging air bubbles, a rubber roller is used, this will get rid of them.

So that the joints are not at all noticeable, you can seal the seam with thin paper tape. Do not start wallpapering surfaces until the substrate is completely dry. This may take 1-2 days.

There are several prerequisites for gluing:

In order not to affect the quality of gluing, such work should not be carried out at high air temperatures (no more than 10 degrees). The result can be disappointing, because individual parts of the sheet sometimes do not stick. The best time for pasting is autumn or spring.
Wall processing is a must! For these purposes, a primer or glue is suitable.
Having smeared 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 craftsman.

Description and reviews of the background under the wallpaper

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

Buyers emphasize availability for 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 it is not planned to cover the surfaces with plasterboard, such a finish will become indispensable.

Manufacturers promise a number of benefits with the use of such wall coverings.:

thermal insulation. You can insulate the walls well, get rid of the fungus and prevent condensation.
Surface leveling. 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 pasting wallpaper.
Noise protection. The sound insulation of the material, although not completely, but 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 indignantly note that this coating can completely fall off the wall. Others, on the contrary, praise a similar experience of warming surfaces.

Due to the fact that there are much more positive reviews than negative ones, it can be assumed that the dissatisfaction of some is most likely caused by a violation of the 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 not start wallpapering before the substrate is completely dry, so it is better to wait a few days. Roll wallpaper must be glued on top of the glue intended for this purpose. Moreover, the coincidence of the joints should be avoided, that is, the edge of the wallpaper sheet should be located in the center of the substrate.

But in any case, before you start gluing surfaces with such materials yourself, it is important to familiarize yourself with 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 make the perfect wall decoration, the surface will have a great look and make the room more comfortable and warm.
