Underlayment under the wallpaper allows you to reduce the noise level and improve thermal insulation.

The soundproofing underlay improves indoor living conditions by reducing the noise level in the rooms.

From the text you will learn how to choose and how to glue the substrate under the wallpaper.

Purpose of the basis

Wallpaper bases have been used for a long time. About 30 years ago, old newspapers were used for this, and then they were replaced by special paper.

Modern wallpaper bases are high-tech materials that can not only facilitate the process of wallpapering walls, but also perform the functions of insulation and sound insulation.

Wallpaper underlay is a wall covering with insulating properties.

Typically, wallpaper substrates are made of polyethylene foam, finished with paper sheets on the back and front sides.

Instead of polyethylene foam, cork or interlining can be used to make the substrate. Substrates can be glued under any type of wallpaper.

This finishing material has the following advantages:

high strength - it is difficult to tear;
environmental safety;
prevents condensation;
serves as soundproofing.

The wallpaper backing is a soft roll finish, but despite this, it has high strength.

There are reviews on the substrate under the wallpaper, saying that it can withstand several wallpaper re-lays. New ones are simply glued onto the old substrate without removing it from the wall.

The material prevents the appearance of mold on the walls, ensures silence in the room. In addition, with the help of a substrate under the wallpaper, you can even out the bumps on the walls.

Professionals are increasingly advised to stick wallpaper not on bare walls, but on substrates, since the level of sound insulation in modern apartments leaves much to be desired.

Despite the fact that wallpaper substrates are a versatile material with a lot of advantages, they also have disadvantages:

not suitable for wet areas;
not suitable for thin wallpapers - in this case, the substrate may shine through;
will not be able to isolate the room from extraneous sounds at a strong noise level.

Substrate mounting

How to stick the backing to the wall:

the surface is freed from wallpaper;
remove water-based paint or whitewash;
the recesses are leveled with putty or alabaster;
the wall is primed with PVA glue
24 hours before the sticker, the substrate is cut and allowed to rest on a flat surface.

When working with a non-woven substrate, glue is applied not to it, but to the walls.

Tip: Immediately remove excess glue from the joints with a napkin.

Pasting starts from the window and moves in a circle. At the junction of two walls, the sheets must be end-to-end - pasting the corner with one sheet with an inflection is not allowed.

During the sticker, the sheets are coated on one side, held for up to 10 minutes and glued end-to-end.

For gluing the substrate, use polystyrene foam glue or adhesive for massive wallpaper. The substrate is glued in the same way as in the butt way.

Air accumulations are removed by ironing the pasted sheet with a plastic spatula or a piece of dry, clean cloth. The seams are sealed with adhesive masking tape.

Soundproofing must hang on the wall for at least a day before wallpaper can be pasted on it.

Glued to the wall, the substrate does not deteriorate for decades. The material of the leading manufacturers is guaranteed for 50 years!

The sound-proofing and warming effect of pasting the walls with wallpaper underlay will be especially noticeable in rooms, one of the walls of which opens onto the entrance.

The concrete walls of panel houses have poor thermal insulation, and through the walls facing the cold entrance, the apartment loses a lot of heat.

Important: The material must not be applied if the room temperature is below 10°C and the humidity is below 70%. Under such conditions, the sheets will not be able to adhere with sufficient strength.

After gluing the walls during the day, drafts should not be allowed to appear in the room.

Key manufacturers of finishing materials in Russia and the CIS countries produce substrates under the following trademarks:

Ecohit - produced by the Izhevsk Plastics Plant, removes the cold radiation of the walls, reduces the noise level. Ecohit does not absorb moisture, is not afraid of dampness;
Poliform - protects walls from condensation, improves sound insulation, reduces heating costs. Poliform is odorless, as it is made without freon and butane. The material does not crack when the foundation of a new house shrinks, is not damaged by mold fungi and bacteria, and does not collapse for 50 years;
Penolon - a heater 7 mm thick. The closed porous structure makes it durable and warm. Finishing with paper on both sides allows you to stick foam on any wall. It can be used for internal insulation of houses made of timber, concrete, brick, cinder blocks.

The listed manufacturers produce material in rolls 0.5 m wide, 14 m long.

Sticking Tips:

do not use the substrate in rooms with humid air;
walls damaged by a fungus are cleaned with antifungal chemicals before pasting;
if gaps appear after gluing, then they are sealed with narrow strips of paper using PVA glue.

The soundproofing effect of the substrate sticker will not allow you to protect the room from strong noise - in this case, other, more effective methods of soundproofing will be required.

The material is environmentally friendly and can be used in bedrooms and children's rooms.

The PE foam backing is easy to cut and the paper backing makes it easy to stick to the wall.

Despite the small thickness, the material helps to save heat - the total effect of its use throughout the entire heating season can be quite significant.

Types of substrates for wallpaper

Substrates can be made from the following materials.

Polyethylene foam - in the distribution network this material can be sold under the name polyfoam or isolon.

All these names belong to the same material - foamy, lightweight, capable of withstanding extremely high and low temperatures (from -60 o C to +90 o C).

Heat-insulating specialists claim that foamed polyethylene, in terms of its heat-insulating qualities, replaces a half-brick wall.

Polyethylene foam is used to insulate walls made of materials with low thermal insulation ability.

For example, concrete freezes quickly at sub-zero temperatures, and polyethylene foam glued to it from the inside will retain heat and increase the comfort of being in the room.

The cork cover is eco-friendly and natural. It not only retains heat, but also has high sound insulation.

The cork substrate is used in recording studios, that is, where it is especially important that extraneous sounds do not penetrate from the outside.

In a room whose walls are covered with cork under the wallpaper, you will not be disturbed by the barking of a neighbor's dog, crying children, playing musical instruments, street noise and other unpleasant acoustics.

As a heater, cork is inferior to foamed polyethylene, but only slightly. The weak point of the rolled cork is the complete absence of hydroprotection.

The material easily absorbs moisture, so in case of flooding it will definitely peel off. Cork is sold in sheets, as it is too rigid and hard to roll into a roll.

A heat-insulating non-woven substrate for wallpaper or repair non-woven lining has recently appeared on the finishing materials market, but professionals have already managed to like it.

Unlike polyethylene and cork, repair non-woven fabric has an important feature - it is vapor-permeable, so it can be used in rooms with high humidity.

In addition, the material has increased elasticity and is great for leveling walls.

Repair interlining can be used to decorate any living room, it has one hundred percent environmental safety.

The disadvantage of this material is the high price - repair interlining is more expensive than polyethylene foam and even cork.

The role of the substrate under the wallpaper can be played by hard materials: drywall or plywood. Their disadvantages include more complex than roll materials, installation and a decrease in the volume of the room.

The layer of air remaining between the sheets and the wall surface serves as a heat-insulating cushion, but it does not protect against sounds.

In addition, cold and warm air meet in such a gap, which means that condensation forms, which leads to mold and decay of wood and paper finishing materials.

Before starting work, you need to read the instructions. Products from different manufacturers may differ in the method of gluing.

Some types of underlays need to lie flat on the floor to level out. Other materials do not need this, because according to the technology, they are supposed to be impregnated with glue before gluing, after which they will become heavier and level out on their own.

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 pasting 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.

Substrate for wallpaper (video)

If you want to stick wallpaper on top of the thermal insulation from the inside of the house, then the choice of the insulation used must be approached as carefully as possible, since not every material is suitable for this.

In this article, heaters will be presented, which are the best options for subsequent wallpapering. Their technical characteristics, as well as the technology for mounting these materials, will be considered.

1 Is it possible to glue wallpaper over foam plastic?

The most popular insulation was and remains polystyrene foam - ordinary foam. Due to the minimum cost and good thermal insulation characteristics, this material is used everywhere - for the insulation of walls, facades, ceilings, floors, and so on.

Of course, the rationality of using this insulation is difficult to dispute, but it should be understood that polystyrene foam is not the best choice for direct wallpapering.

Firstly, the surface of the foam does not have sufficient rigidity, as a result of which, even with minimal external influence (someone leaned against the wall, or the wall caught on some object), the wallpaper will break through.

Secondly, since the foam, as it is a slab material, at the same time, for effective insulation from the inside of the walls, you will need at least a 5-centimeter layer of insulation, the foam joints after pasting will stand out very much under the wallpaper.

Thirdly, when the moment comes for a redecoration of the room, and you need to change the wallpaper, you will also have to change the insulation along with them, since you will not be able to tear off the wallpaper from the foam surface without damaging the latter.

And the last factor, due to which it is impossible to glue wallpaper on foam plastic, is the issue of fire safety, since according to SNiPs, polystyrene foam must be insulated with a layer of non-combustible material.

If you want to insulate the walls from the inside of the house with foam plastic, then for subsequent wallpapering, you can either sheathe the thermal insulation with drywall, or cover the insulation with a reinforcing plaster composition using fiberglass plaster mesh. But for such a case, it is sometimes easier to use polyurethane.

Now let's talk about heat-insulating materials on which you can glue wallpaper without any additional preparation.

1.1 Polyph

One of the easiest materials to use is polyfoam - a rolled insulation made from foamed polyethylene foam.

From the side adjacent to the wall, polyfoam does not have an additional coating, however, from the outside, the material is covered with special high-density paper. The paper surface has good strength, which makes it possible to stick on such a heater, both ordinary and heavy vinyl wallpapers.

Polyform is produced in roll form. The insulation has the following dimensions: length - 14 m, width - 50 cm, thickness - 5 mm. The density of the material is 30 kg/m³.

Thermal insulation with polyfoam, as well as, despite the small thickness of the material, is quite effective, since the insulation has a minimum coefficient of thermal conductivity, which is 0.03 W / mk, which is similar to a 12 cm brick wall, or 5 cm of wood.

The advantages of polyform, in comparison with other wall insulation for wallpaper:

Polyfoam, in addition to insulation, significantly increases the sound insulation of walls. The noise reduction index of the material is about 30 dB, while it copes equally well with both impact noise and airborne sound;
The polyfoam has a structure of closed cells, thanks to which the polyfoam is not prone to water absorption and vapor diffusion. Wall insulation with foam foam from the inside does not require additional vapor barrier and waterproofing;
Mechanical strength and resistance to deformations - the base of the polyfoam is made of molecularly cross-linked polyethylene, which guarantees maximum strength of the material (with an external load of 2000 N / m², the modulus of elasticity of the polyfoam is MPa);
The minimum weight (260 grams per 1 m²), and the high elasticity of the material make wall insulation with polyfoam extremely simple and trouble-free;
Chemical inertness - none of the modern wallpaper adhesives will do any harm to the polyphon (even);
Durability - microbiological resistance, together with mechanical strength and chemical inertness, guarantee a long service life of the polyfoam, which is about 50 years, without loss of the functional properties of the material.

The disadvantages of polyfoam can only be attributed to the lack of fire resistance, but this is typical for all heaters made of foamed polymers.

Installation of the polyfoam is carried out in the following sequence:

The height of the walls is measured, and the roll of polyfoam is cut into pieces of the required length;
Old wallpaper and a layer of damaged plaster are removed. All cracks, potholes and other defects found on the surface of the walls are puttied;
The wall is covered with a deep penetration primer. This can be omitted, however, the presence of a primer will significantly reduce the consumption of the adhesive;
After the primer dries, glue is evenly applied to the surface of the polyfoam and to the wall surface, after which the insulation is fixed on the wall. It is important that at the same time the temperature in the house is higher than +10, and the air humidity does not exceed 70%;
The joints of the polyfoam are glued with masking tape as, after which the insulation is left for 72 hours, which the material needs to dry. After the time has passed, the walls are pasted with wallpaper.

1.2

The only completely natural thermal insulation material that can be used for direct wallpapering is cork insulation.

The technical characteristics of cork insulation are as follows: thermal conductivity coefficient - 0.04 W / mk, density 100-130 kg / m³, flammability class - G3 (normally combustible material), nominal weight - 200 kg / m³.

As an insulating substrate for wallpaper, as a rule, cork thermal insulation with a thickness of 10 mm is used.

Cork insulation has the following advantages:

Environmental friendliness, and, as a result, complete safety for human health;
Durability;
Cork is a material that does not accumulate static charges;
Microorganisms do not start in cork heaters, moreover, such a heater does not mold even with very damp air in the room;
Cork thermal insulation, in addition to improving the temperature in the house, guarantees high-quality sound insulation of housing;
The cork substrate under the wallpaper allows you to hide defects and uneven walls.

According to reviews, natural cork insulation helps maintain the optimal temperature inside the house.

In winter, cork thermal insulation allows, with a similar heating of the house, to get a temperature 2-3 degrees higher than in an uninsulated building, and in summer, cork prevents the transfer of heat from warm walls to indoor air, as a result of which comfortable coolness remains in the building.

The only disadvantage of cork insulation is the cost, since natural material is an order of magnitude more expensive than artificial insulation.

The technology of wall insulation with cork insulation is as follows:

Surface preparation is in progress - old wallpaper, plaster are removed, the wall is leveled with plaster, all cracks are sealed;
After the plaster has dried, the wall is covered with a deep penetration primer;
Cork insulation is cut into sections of suitable length;
According to the instructions, a special glue for cork materials is bred;
An adhesive composition is applied to the surface of the insulation and the wall with a roller, after which the thermal insulation is fixed on the wall. It is necessary to glue the insulation end-to-end;
The seams between the sheets of insulation are sealed with adhesive;
If necessary, excess insulation must be cut with scissors. It is not recommended to use a knife, as it can tear the insulation wet from the glue.

When developing the design of our apartment, house, we mainly rely on the decorative component, but during the repair itself, we need to take care of the technical aspects. For example, to create a comfortable living environment in all rooms.

Packing building material for insulation

Insulation and its types

In order to create a comfortable microclimate inside the premises of a house or apartment, it is necessary to insulate the walls. To do this, we need to purchase and mount a heater on them. There is nothing complicated in these works, you can easily do it yourself, besides, there are a huge variety of various installation instructions for every taste on sites on the Internet.

When choosing methods of insulation, I really want to preserve the dimensions of the room as much as possible. We still need a precious place for arrangement, so we don’t need to build large-sized structures for insulation. Consequently, we will certainly refuse to build plasterboard walls inside the premises.

Despite the fact that this method allows you to level the walls and additionally insulate them, it is very laborious and requires a large number of different materials. It would be quite logical to use this method of basic insulation for a private house.

Substrate under the wallpaper brand Ecohit

We need to choose the narrowest, most reliable material, it is very important that the insulation performs its functions efficiently and does not harm the health of the people living there.

There are a lot of options that the construction market offers. However, they can easily be divided into two main groups:

Plaster with increased thermal insulation properties.
Insulation under the wallpaper, wound in rolls.

Let's consider in more detail both available options, their advantages and disadvantages.

Plaster

In hardware stores there is a specialized plaster for insulation. The subtleties and nuances of the material and work with it are known to sellers, they can be consulted, choose the best option for your needs.

It is best when you have a rough idea of what the final result should be. Then you will not be negligent about the means to achieve it. In addition, not everyone can plaster walls with high quality, and if you decide to do it yourself, you should know general data about materials and working with them.

Even if you entrust plastering work to professionals, you should carefully consider the choice of insulation so that its functionality is enough for many years, and not for a couple of years.

It is up to you to decide which type of thermal insulation plaster is needed, it all depends on its properties and the quality of the filler. The only thing that unites all types of plaster insulation is their environmental component, they are all absolutely harmless to humans and animals.

Aggregate for plaster based on foam glass

Among the most popular fillers are:

Sawdust, inherent in the cheapest and simplest type of natural insulating plaster. Like any other natural materials, sawdust does not tolerate moisture well, so this type of insulating plaster will not work in damp rooms (in a private house, on a loggia).
Expanded polystyrene refers to modern materials with excellent thermal and sound insulation characteristics. Apply such plaster to the walls, and the noise of the environment will remain outside the window. The disadvantage of expanded polystyrene is its high flammability, moreover, when burned, it releases toxins harmful to humans.
Despite their strange names, perlite and vermiculite are environmentally friendly mineral fillers with good resistance to various influences, non-combustible, and safe for people. The disadvantage of this filler is considered to be a high degree of moisture absorption, therefore, after plastering the walls, they have to be additionally isolated from the effects of humid air.
Another modern material is foam glass. The level of its thermal insulation is not the highest, but the material is absolutely non-flammable, has excellent moisture resistance, and is made from environmentally friendly materials.

Note that when using plaster with mineral fillers, the surface of the walls will be porous and rough, therefore, before wallpapering, it should additionally be plastered with finishing putty.

But when using rolled heaters, such manipulations are not necessary.

Roll option

If you remember, earlier, before sticking beautiful, decorative wallpaper, the walls were pasted over with ordinary newspapers. In old houses, you can even see several layers of such newspapers. At that time it was an excellent insulation and leveler for walls.

Standard roll of insulation half a meter size

But those days are long gone, new materials have appeared, the production technology of which has gone far ahead. Now the insulation for wallpaper is sold ready-made, in rolls, and it is made of a variety of materials:

Expanded polystyrene can be not only a filler for heat-insulating plaster, but also sold in sheets as a substrate for wallpaper. At the same time, it retains all its functionality in this form. Gluing it to the wall is quite difficult, you need to use a good glue, best for heavy canvases, and at the same time it is reasonable to add a little gypsum-based finishing putty to its composition. The polystyrene foam substrate is single-layer, and sometimes paper is glued to it on one side as a second layer. This is done to facilitate wallpapering, because they stick extremely poorly to the material itself.
Foam polyethylene of the foamed type is superior in many respects to the substrate described above. Today it is the most popular insulation for wallpaper. It is produced by a variety of manufacturers, from well-known brands one can distinguish, (often called Poliform by the people). Roll insulation made of polyethylene foam is glued on both sides with paper. This is done to facilitate gluing the insulation itself on the wall, and subsequently the wallpaper on it.
Cork is one of the most famous heaters, and the most natural one. The material has good thermal insulation characteristics, does not transmit sound well, and looks quite nice. It can even be used as a finishing touch if desired. The main drawback is poor moisture resistance, which is leveled by treating the cork substrate with special water-repellent wax-based compounds.
Wallpaper with applied insulation can be used solo. In their structure, foil, elements of spunbond covering material, various types of oilcloth material can be present as a heater. Unfortunately, finding such wallpaper options is quite difficult, but choosing the right color is even more difficult. Nevertheless, the use of such materials for wall decoration significantly saves repair time and facilitates many processes.

You can choose any of the above rolled heaters for yourself, and you will know for sure that it will help level the walls, insulate them, add a room, in some cases, vapor barrier.

In addition, the shelf life of materials is calculated in tens of years, which means that you do not need to change them every time you stick new wallpaper. Some types of substrates are easily removed from the wall for reuse.

Wall mounting

Despite the fact that the roll insulation is created from different materials, it is mounted on the wall according to the standard principle. All differences will be in the composition of the adhesive that will be used, and, accordingly, in the drying time of the substrate on the wall.

Conditions for carrying out installation work with a substrate in the room

To glue the insulation on the walls of the apartment, you have to do the following:

First of all, it is worth preparing the surface, for which you need to remove the old wallpaper, plaster the wall, smoothing and patching up large cracks and bumps. Small defects in the wall surface can be left, they will close.
Next, the surface of the wall must be primed. This is done either with the help of glue, with which we will glue the substrate, diluted in a weaker consistency, or with the help of a special primer composition. After the primer, you must wait until it is absorbed into the wall and dries.
It is recommended to cut the roll insulation into pieces of the required length in advance so that it can lie down and level out. This will make it much easier for us to glue it. When cutting the canvas, add a little material for insurance.
We prepare the adhesive composition according to the instructions on its pack. If we are dealing with a substrate with a top layer of paper, then we apply glue to the wall and to the cut pieces, while letting them soak in the composition for literally 5 minutes. If the substrate is equipped with non-woven edges, then it is enough to spread the wall, and the material will easily attach to it.

Next, we proceed directly to the installation of canvases on the walls. This process is reminiscent of wallpapering, the pieces are also glued together and carefully smoothed out. Air is expelled from under the canvas and it is firmly glued to the wall. It is convenient to use a rubber roller, it will create the necessary pressure and will not damage the insulation sheet.
After the insulation has dried, after about 1-3 days, we seal the joints of the canvases with ordinary masking tape. Krepp will give solidity to our design.
Now our walls are qualitatively insulated, and you can proceed directly to gluing the wallpaper itself.

Wall insulation will allow us to create the most comfortable living conditions. It will serve us for a long time, no matter how many wallpapers hang.

Warming is one of the important stages in the arrangement of an apartment or house. Insulation for wallpaper is a special material that allows you to insulate the walls of the dwelling and carry out subsequent pasting.

Advantages

Such material has the following advantages:

eliminates the effects of dampness in the premises (fungus, mold, various microorganisms);
reliably insulates the walls (on average, the temperature in the room rises by 2 ° C);
has good soundproofing properties;
eliminates surface defects (this applies to small irregularities);
it is simple and easy to install (on the market today there are several types of insulation for wallpaper, but basically this material is glued like ordinary wallpaper)
has a very reasonable price.

Types of insulation for wallpaper

Today, the most popular are three types of insulation for wallpaper.

roll material

This heat insulator is a material, on the one hand, equipped with a reinforcing base made of foil or paper. Foil rolled insulation due to its heat-reflecting properties has a wide scope.

The material with a paper base is characterized by improved adhesion to the surface of the walls.

Today you can buy a heat insulator for wallpaper, which has a paper coating on both sides.

polyph

This type of insulation for wallpaper is made of polyethylene foam. Such a material is similar to heavy wallpaper and has paper layers on both sides applied using thermal lamination.

"Polyfom" is a material that can be glued to the surface of the walls on its own, without resorting to the services of professional craftsmen. But it is necessary to adhere to certain rules for its installation.

The base is carefully leveled, since with high-quality wallpapering of the walls, all bulges and irregularities will be very noticeable.
After decorating the surface, Polyfom should dry completely (at least 3 days), after which you can proceed to the subsequent decoration of the walls with wallpaper.

Today, Polyfom is the most popular among consumers, as it is glued much easier than all other types of heat-insulating materials and has high thermal insulation characteristics. In addition, this material is completely safe for the life and health of people, pets and the environment.

If you are not eager to practice or there is no way for this, then the cork heat insulator under the wallpaper is just for you. It does not require pre-leveling and will easily hide all surface defects. The undoubted advantages of such a heater include high thermal insulation properties. People prone to allergies should prefer this material.

Such a heat insulator has a beautiful texture, without mechanical defects. But it still needs some finishing touches. This is a vapor-permeable material, condensation does not form on its surface, so it can be used in rooms with high humidity. In addition, the cork does not absorb odors.

But cork insulation has a drawback: to insulate a room with such material, you will need special glue.

When choosing a heater that can be used for wallpaper, focus on the cost of the material, its technical characteristics, installation features.

Penoplex can also be used for thermal insulation of the inner side surfaces of the dwelling. It is an extruded polystyrene foam endowed with low thermal conductivity.

Most often, wallpaper substrates are used in rooms in which a home theater is installed, in dwellings, the walls of which are very thin.

Mounting Features

Whatever insulation for the walls inside your house you choose, the method of application, in principle, will be the same.

Consider the features of applying a material such as "Polyf".

Stage 1 - surface preparation.

The walls must be cleaned of the old coating (wallpaper, paint, peeling plaster). Pronounced irregularities (deep cracks and potholes) are sealed with plaster. After that, the surface must be leveled and a layer of putty mixture applied. It must dry completely. The walls must be dry and smooth before applying the heat-insulating material.

Stage 2 - primer treatment.

The deep penetration primer mixture is applied with a spray gun, brush or roller. Some craftsmen replace such material with PVA glue.

Stage 3 - gluing insulation.

The material is cut into sheets of the required length and glue is applied to them. The insulation should lie down for 5-10 minutes, after which it is glued to the walls. A special adhesive composition is applied both to the side surfaces and to the heat insulator in two layers. Apply insulation to the walls and level it with a heavy roller or wallpaper spatula.

Make sure that there are no air bubbles under the insulation, avoid drafts and changes in humidity (about 70%) in the room, the temperature in the room should not be lower than +10˚ C.

You need to glue "Polyf" end-to-end. If desired, the joints can be glued with tape.

After application, the material is allowed to dry for 72 hours. Then the room must be ventilated.

Stage 4 - pasting surfaces with wallpaper.

When choosing an adhesive for a heat insulator, opt for a composition for heavy wallpaper. Be sure to follow the instructions on the package.

The cost of insulation under the wallpaper

You should not save on quality and purchase products from an unverified manufacturer. The average cost of a heat insulator for interior work depends on the chosen brand of finishing material and, of course, the heat insulator itself. The most inexpensive of the presented types is considered to be rolled insulation (800-1000 rubles per roll). The price of a cork heat insulator depends on its thickness and ranges from 800 to 6000 rubles. "Polyf" is sold in packages (from 1100 rubles). Its length is 7 m, thickness - 5 mm, width - 0.5 m.

The walls inside the apartment, insulated with these materials, will not let you freeze at a time when it has already become cold outside, and the heating has not yet been turned on.

Having spent quite a bit of time, you can make your home warmer and more comfortable for your stay, save on heating.
