Soundproofing under the wallpaper is noisy. sound-absorbing

Gone are the days when wallpaper was simply glued to the walls of apartments. Currently undergoing a special internal walls to achieve a longer service life of the coating, to make rooms protected from external sounds and noise. For this, a special wallpaper substrate is often used, which is an excellent tool for leveling and.

Budget real estate has poor sound insulation of walls, so it is recommended to use a substrate during repairs, on which wallpaper will then be glued.

First of all, wall covering is used to make the room warm and protected from external street noise. Also substrates for wallpapers are excellent material, which helps to decorate the walls and evenly glue the material. Other benefits of this technology include:

High degree of strength, so the material will not tear quickly.
Substrates are made from environmentally friendly materials.
Prevents formation of condensate and fungi.
Creating a comfortable atmosphere in the room.
Long operating time.

Thus, the range of application of substrates is diverse. The use of the material allows you to solve several problems at once, which are typical for modern apartments and houses.

Types of substrates

The interior decoration of the rooms depends on the type of selected substrate. It is chosen based on the following factors:

The number of people in the apartment or house.
Housing location.
Influence temperature regime, nature and weather conditions.
The level of humidity and dampness.

There are several types of wallpaper substrates, which are most often used for interior decoration premises:

Foamed polyethylene, which is characterized by a porous structure, lightness, low thermal conductivity. This type of substrate is used to create heat in the apartment. This material allows you to create sound insulation, retains its qualities at temperatures from +60 to +90. It is possible to glue polyethylene foam on concrete walls reducing heating costs. This mat is sold in rolls.
Cork backing is made of natural material, therefore it is safe, environmentally friendly, has an excellent level of sound insulation and adhesion. Recommended for use in areas where thin walls if the "effect" of street noise is constantly present in the house. This will protect the apartment or private house from the barking of dogs, the voices of neighbors, the signals of cars, the sounds of repairs from neighboring apartments. Cork is wonderful heat-insulating material, but she is afraid of moisture and water. Therefore, for regions or for apartments with a humid climate, this type of substrate is not recommended.
Non-woven substrate - made from modified cellulose, which allows the material to remain resistant to steam. Thanks to this, the normal process of airing and ventilation of the walls, drawing moisture out of the living quarters takes place. Interlining is elastic, which allows it to be used on walls with irregularities.
Drywall is a hard type of substrate for wallpaper, it is used less often than other materials, because it is afraid of dampness and moisture. When using drywall, you must leave a gap between the wall and the material.

acoustic wallpaper

In the market of finishing materials you can meet and special kind wallpaper - acoustic. They are sold in rolls or slabs, so they are convenient to use for pasting the ceiling and walls. Acoustic wallpapers have a high level of sound absorption. Surfaces perfectly reflect sound, resulting in a reverberation effect - the sound creates an echo. To obtain such an effect, the structure of acoustic materials is made from the following materials:

Cellulose, i.e. paper. Sometimes it is replaced with non-woven fabric. These materials play the role of the basis of the wallpaper.
The outer layer (top) is covered with acrylic fabric or other fibrous materials consisting of fibers. Due to this, the villi absorb sound.

There are acoustic wallpapers made of cork, wood-based finishing materials. In particular, from veneer, from bamboo, from grass. The thickness of the wallpaper is 3-4 mm, depending on the material.

Soundproof acoustic wallpaper can be used to decorate the following rooms:

Houses where the level of sound insulation is low.
cinemas.
Canteens.
Bedrooms.
Meeting rooms.
Cabinets.

Advantages and disadvantages

Acoustic wallpaper is used for wallpaper substrates, which allows you to create a high-quality level of noise protection in apartments and houses. Other advantages of the material include:

It is very easy and simple to work with the substrate, which allows you to cut it into pieces without much effort, as well as stick it on the walls.
When gluing, workers will not suffer from dust and odor.
Environmental friendliness of the material.
Long service life.
Moisture resistance.
Excellent fire performance.
Impact resistance.

Also a high level of practical use, since the wallpaper is relatively inexpensive. Anyone can purchase material to create a substrate for wallpaper. Fasteners are not used during repairs. It is also important that soundproof wallpaper do not eat up the space of the premises, like other substrates.

The disadvantages of using acoustic wallpaper include the following factors:

Due to the small thickness, the material is not always suitable for wall decoration - they can be translucent.
It is not always possible to obtain a high level of noise protection for an apartment.

Selection criteria and acoustic wallpaper manufacturers

In order to choose the right substrate designed to isolate a room from extraneous noise and sounds, it is necessary to adhere to the following criteria:

Special purpose.
The size of a room or apartment.
Prices per roll or package of wallpaper.
Interior interiors.
The condition of the walls - whether they need to be corrected, primed, eliminate irregularities.

The main brands of acoustic wallpaper that can be found on the market of finishing materials include:

German brand AMF, which produces wallpaper in the form of plates. They are made from clay, starch, water, perlin and mineral fiber. The surface can be different - smooth, perforated, structural.
, Denmark. Also available as slabs mineral wool, fiberglass, glue and coated with white acrylic paint.
Rockfon, which are produced in Holland, France, Denmark. Panels are created on the basis of basalt fiber and stone wool which allows excellent sound absorption.

Soundproof materials, which are used to create comfort in the apartment, differ in cost and the material from which they are made.

Before buying, you need to check with the experts for which room such wallpapers are suitable, whether they can be used for the substrate.

Pasting process

The substrate is very easy to use, so you won’t have to work hard with it during work. You only need to do the following:

Completely clear the wall of wallpaper or other material.
Large cracks and gaps are leveled by plastering over.
The wall must be leveled so that there are no large differences from irregularities on it. If such a need arises, then the wall should be re-primed.
The wall must be clean and dry.
The backing roll is cut into webs of the length required for gluing. It is worth remembering that for non-woven fabric they buy a special glue for non-woven wallpaper, which is applied only to the wall. For polyethylene foam and cork, it is necessary to lubricate the substrate and wall with glue. Having smeared glue, we wait from 3 to 5 minutes so that it dries slightly. This will make it easier to place sheets of material in the right place on the wall.
The strips of the substrate must be glued joint to joint, and then the seams are strengthened with paper tape.

The substrate dries within 72 hours, after which you can begin to glue the wallpaper. You should not do this before, otherwise they will not stick well and “wrinkle”.

It is better to wait a few days until the substrate under the wallpaper is completely dry. To ensure that the pasting of the room does not suffer from the poor quality of the work performed, it is not recommended to carry out work at high temperatures. The ideal temperature is +10, so repairs should be done either in spring or autumn. In the room where they plan to work with the wallpaper substrate, there should be no drafts.

The lining provides thermal insulation. It also provides sound insulation, noise insulation, vapor barrier. It is easy to work with the material, even a non-professional can cope with gluing. The advantages of using a substrate for wallpaper include the following: it levels the surface before wallpapering, it is also easy to glue, which makes it possible to do repairs yourself. The material protects against condensation and fungal infections of the walls, is not afraid of dampness and does not absorb moisture, there is no need to do top coat, you can re-paste the wallpaper several times.

If a person wants to protect his home from extraneous noise, then you need to buy a special substrate. Soundproofing and soundproofing materials are used for protection.

Soft porous material absorbs sound, and soundproof materials repel it.

The best effect is obtained when several types of soundproofing material are used at once. For example, a great effect can be achieved by using drywall and gypsum fiber. Recently, films and plates made of polyethylene or polyethylene foam have gained relevance. The substrate is usually 5 mm thick and the boards are 40 mm thick.

Gluing process

It is not difficult to arrange a substrate, the process is as follows:

The polyethylene foam substrate is cut into pieces of a suitable size;
You must first apply glue to the wall, a composition for heavy wallpaper is suitable;
Glue the backing and when it dries, seal the joints with tape;
Then you can glue the wallpaper.

Plates 40 mm in the apartment should be fixed with special screws. Drywall is “planted” on top of the glue, after which the wallpaper can be glued after a rough finish.

Super thin soundproofing of walls in an apartment under wallpaper: advantages and characteristics

The thin substrate is popular with the consumer due to its performance characteristics.

Wallpaper underlay has the following advantages:

High strength;
Environmental friendliness;
Protection against moisture and fungus;
High sound insulation.

This rolled surface is an ideal material for a finishing coating in the form of wallpaper.

The soundproofing surface is durable, so you can re-glue the wallpaper several times.

Most wanted and different good performance brand materials are considered:

Ecoheat;
Penolon;
Polyph (Trocellen).

These manufacturers are better than others have proven themselves in the market. The Ecohit substrate consists of foamed polyethylene and looks like paper. The structure of the fabric is uniform and dense. Penolon is most relevant for craftsmen, the material looks like a cross-linked polyethylene foam. Polyfoam has undeniable advantages, it is easy to use, it is clean and durable.

High-quality insulation - a substrate for wallpaper

The most effective use of the material in the apartment, country house where individual heating systems are installed.

Soundproofing, insulation Izolon from Ecohit is suitable for people who want to solve the problem with soundproofing.

For example:

Noisy neighbors;
Noise in the street;
Isolation from neighbors (so that they do not hear).

The material has closed pores, due to which the effect of isolation is achieved. It is impossible not to mention the environmental friendliness of the insulation from Ecohit. This product is clean and safe as no toxic additives are used in its production.

Soundproofing, wallpaper substrate: reviews of masters and characteristics of the material

Repair masters always carefully select the material for implementation repair work. And this is not surprising, because the final result and the durability of the repair depend on the materials.

Based on the reviews of professional repairmen, it was possible to highlight the advantages and disadvantages of the substrate under the wallpaper with the soundproofing effect:

The substrate is not recommended for use in rooms with high humidity.
Before installing on the wall, the surface must be treated from the fungus.
Wallpaper for the finish coat must be chosen dense, otherwise the substrate may shine through.
The underlay alone cannot create complete sound insulation, so it is recommended to use at least 2 materials together.
The material is easy to cut, glue, it is a pleasure to work with it.
Wallpaper backing is safe and environmentally friendly, it can be arranged even in a children's room.
Perfectly retains heat in the room, thanks to which it received mass positive feedback both from the consumer and from the repairmen.

Whichever substrate the consumer chooses, he will appreciate its stable structure. Thanks to the material, you can create not only sound and heat insulation, but also level the walls before finishing the room.

Noise isolation in the apartment: how to glue the substrate under the wallpaper correctly

Many will be interested in how to properly stick a well-chosen substrate. The first thing the masters recommend is to prepare the surface well for gluing.

It is necessary to remove all the old coating from the wall surface, paint, wallpaper. You should also cover the cracks and cracks.

Then you need to treat the walls with a primer. It is equally important to prepare the substrate itself, for this it is pre-cut into pieces and placed under the press. Next, brush inner surface backing adhesive and can be glued on the wall. The process resembles the traditional pasting of walls, but only in this case it is necessary to stick the canvases end-to-end.

Important! Do not apply glue to the joints, as this will cause the material to stick together. It is also necessary to ensure that all air bubbles come out from under the canvas. You can expel air with a special rubber roller. The joints after gluing and drying the canvas can be sealed with paper tape.

Experts talk about special conditions when sticking the substrate:

It is necessary to glue the substrate at an air temperature of no more than 10 degrees, otherwise the quality of work will not please. The best time for repairs spring or autumn.
It is imperative to prime the walls.
There should be no drafts in the room.
It is important to wait a few minutes after lubricating the canvas with glue, then the substrate will be easier to stick.

Following simple rules, you can equip the walls with high quality and create good sound insulation in room. Despite the mixed reviews about the substrate under the wallpaper, the material remains relevant and in demand.

When describing and applying various kinds substrates opinions among consumers and craftsmen were divided. The buyers attributed the advantages of the material to the convenience of working with the substrate, the acceptable cost of the material and the durability of the repair. A relative disadvantage is not the possibility of creating ideal sound insulation; for a better result, several types of material must be used at the same time.

Substrate for wallpaper how to glue (video)

The substrate is usually purchased by residents apartment buildings who want to isolate themselves from neighboring sounds. Due to the fact that there are many times more positive reviews, the wallpaper substrate is popular and in demand among professional builders, and for people who make repairs with their own hands.

Manufacturers Elitis (France) and Omexco (Belgium) produce special wallpapers that are distinguished by low sound absorption. They do a good job of this task, so they are often used in cases where you need to provide maximum sound insulation in a room, in a kitchen or in non-residential premises. It is worth noting not only the excellent performance properties of wallpaper, but also their appearance. Sound-absorbing wallpapers produced by Elitis and Omexco differ in texture and look expensive. These are premium products that are used to create luxurious interiors, implementation of unique design projects.

Most of the world's population lives in different cities, some people live in millionaires, some in the provinces. It is undoubtedly convenient to live in cities, since the infrastructure here is highest level, but there are enough problems in such living.

Wallpaper is able to extinguish sound vibrations

People in cities get very tired of all kinds of noise, it is difficult to find a quiet, secluded place, even in their own apartment, because neighbors or sounds from the street will be heard.

Soundproofing

Knowing this problem, engineers are trying in every possible way to increase the sound insulation of a residential building by producing specialized building materials. First of all, they developed double-glazed windows that allow you to tightly close windows, getting rid of excess noise on the streets.

But what if the noise comes from inside the house, for example from neighbors. For this, wallpaper experts have developed special, soundproof wallpapers. Of course, soundproof wallpapers are not a panacea for all annoying sounds, but if you use them in a complex way, along with good double-glazed windows, special materials for floor and ceiling, you can achieve good results.

Only an integrated approach in the fight against sound gives results

Installing soundproof wallpaper will be the first, sure step towards achieving a more peaceful and quiet atmosphere in your home. Let's look at the main types of such material.

Varieties

Soundproof wallpaper is considered to be all those canvases that can successfully drown out loud sounds. In most cases, this is a feature of the material from which the wallpaper is created. Ability to suppress sound waves the following types of wallpaper are available: cork, vinyl, velor, tufting. Let's start in order.

Cork

Cork wallpaper will help create a cozy room with a pleasant aura. Cork wallpapers are considered soundproof, since they are able to reduce sound vibrations several times, and therefore dampen the sound. It is enough to dress the room in cork wallpaper so that you feel the atmosphere of comfort and warmth.

In addition, cork is a natural material, which means that the interior in our room will be not only soundproof, but also safe.

Most often, cork wallpapers are multi-layered, consisting of several durable layers of material. These cork wallpapers are glued with safe adhesives. The multi-layered wallpaper allows you to increase the suppression of noise and extraneous sounds.

Use in the interior of the bedroom cork wallpaper

Hypoallergenic wallpaper from natural materials in addition to their soundproofing qualities, they also have good thermal insulation properties. These qualities will help you keep warm in cold weather, and, conversely, get rid of excess heat on a hot summer day. Cork is very similar in properties to wood, since in principle it is a tree bark extracted from the corresponding tree.

Vinyl

Modern vinyl wallpapers of hot stamping, created on a non-woven base using special technologies, also have good soundproofing qualities. A durable and rigid material with a certain relief is able to block some of the noise penetrating into the apartment from the outside. In addition, a high-quality non-woven backing helps the vinyl material in this.

Vinyl wallpapers are distinguished by increased strength characteristics. Unlike cork counterparts, they will last you much longer, although they have a slightly lower noise reduction level.

High quality and thick vinyl

Positive traits vinyl wallpaper we won’t especially describe them, they are already known to everyone, but we’ll go through more little-known materials. Even less noise reduction for wallpaper made of artificial velor.

Velours

Remember in childhood such soft and rough colored sheets of paper, that's exactly what velor looks like. However, unlike this children's paper, which resembles velvet, artificial velor is more durable and strong.

Such wallpapers have an average level of noise reduction, perhaps even their quality is slightly above average, but certainly not the strongest. But despite this, there should be no problems in working with such wallpapers and in their choice.

Any person can apply noise-canceling velor wallpaper on the wall, and he can do it quite well, without unnecessary difficulties. However, it is not recommended to use velor canvases in wet rooms, since the material has obvious problems with moisture resistance.

Bright, velvet wallpaper in the bedroom

For use in a living room, study or bedroom, this drawback is not critical, but in rooms where it is best to use moisture-resistant or washable wallpaper, artificial velor is categorically contraindicated. Although if you think about it, we need silence in the bedroom, sometimes in the living room or study, but in the kitchen or in the hallway, the noise level is not so important.

In terms of colors and assortment, such wallpapers are quite diverse. You can always find a couple of options for your interior. Continuing to consider strange finishing materials, we move on to tufted wallpaper.

tufting

Tufted wallpaper is a modern two-layer material created from thick fabric and pile. The pile is applied to the fabric using special machines. By and large, these wallpapers resemble an ordinary carpet. However, unlike natural carpets, tufted wallpapers are created exclusively from artificial materials.

Tufted wallpapers have excellent thermal insulation, despite the fact that the porous structure of the canvases is able to pass air through itself. Since the pile is not natural, it is not afraid of moisture and can be easily washed. And if washing seems a little, then it is permissible to use an ordinary vacuum cleaner for cleaning.

Carpet wallpaper in a small bedroom

Such wallpapers are simply glued to the wall; standard techniques are used to work with the canvas. As in the case of velor, you can paste such wallpapers yourself. Glue is used wallpaper, designed for heavy wallpaper. If you doubt such glue, then take construction PVA, you will not lose.

As you probably already noticed, all of the above soundproof wallpapers have both advantages and disadvantages. Let's try to combine them, and see what all the same has more pluses or minuses.

Quality Criteria

Suppose you decide to use the noise-reducing wallpaper from our list, what pleasant and unpleasant moments await us.

Wallpaper with interesting monograms in a large room

An increased level of noise suppression, sound insulation is inherent in all of the above types of canvases.

Full natural naturalness of the material, the absence harmful substances. Cork wallpapers are completely natural, but the rest of the options are all artificial, but not one type of soundproof wallpaper brings harm to a person.

Moisture resistant. We can note this quality in vinyl, taffeta, but proc and velor are very afraid of water and quickly come into a terrible look from it.

Versatile in terms of colors and patterns. Here, only cork, which has limited variability, is in bad shape, but other types of canvases have a wide range.

Enlarged strength characteristics. Only vinyl can boast of great strength, all other types of wallpaper: cork, velor, taffeta do not have outstanding strength properties.

Ease of installation. The cork is the most difficult to mount on the walls, the process must be approached very seriously. It is best to entrust the work of sticking cork wallpaper on the wall to professionals. You can handle the rest of the wallpapers yourself.

Price. The price for all these types of finishing materials is decent, since the production process of each type of wallpaper is complex and multi-level.

Wide selection vinyl wallpaper for walls

The use of soundproof wallpaper in conjunction with other similar materials will allow you to create a cozy and quiet interior in which you will be happy to relax. However, it is worth remembering that wallpaper alone will not cope with this task.

On the other hand, such wallpapers can become an unusual interior solution that will advantageously distinguish your room from the mass of others. Apply modern technological noise-reducing wallpapers with taste, then they will not only help you solve noise problems, but also decorate the room.

The quality of secondary housing and most new buildings still leaves much to be desired. Irregularities in the ceiling and walls are the least that homeowners face. One can generally compose sad songs about the noise from neighbors or from the street, penetrating through cracks and walls, as through a sheet of paper. But demand always provokes supply - a multifunctional wallpaper substrate has appeared on the building materials market, the installation of which, according to manufacturers, solves these problems at once.

The construction axiom - the surface must be carefully prepared before finishing - is not always feasible in practice. Either the lack of money or the unwillingness to get into dirty work becomes an obstacle, but be that as it may, pasting over an unfinished wall is a waste of work. Any defect such as an indelible stain or crack can appear under the wallpaper, especially if they are thin, and utterly distort their appearance.

Roll of insulation pad

This is where the backing for wallpaper comes in handy - reviews indicate that it really contributes to a slight leveling of the surface and its color. There are several types of such substrates, and they all have their advantages and disadvantages:

paper - a thick paper base is especially useful when it is impossible to remove old finish, but it is fragile and does not hide obvious surface flaws;
non-woven - similar to ordinary non-woven wallpaper, they have the same advantages (strength and ease of gluing), and their disadvantages include the high cost of double finishing;
cork - not used as a repair base decorative cork, but technical, so it is cheaper finishing material, absorbs sounds well, but requires installation skills and the purchase of special types of glue;
polyethylene - they are polyethylene foam, on which two layers of paper are applied on both sides, in addition to masking surface imperfections, they serve as heat and sound insulation.

Since the idea of installing thin soundproofing walls in an apartment under wallpaper seems tempting to many, it is worth considering in more detail the pros and cons using the most popular building materials and reviews as an example.

Roll underlay 5 mm thick

Overview of popular heat and sound insulating substrates

The idea of using PE foam as a cheap thermal insulation pad is not new: PE is the most common plastic in the world and, when foamed, effectively prevents heat transfer between two spaces. Naturally, this property was not ignored by manufacturers of thermal insulation, and in construction stores roll materials such as EcoHeat and Penolon are now common. What are their characteristics?

Properties and scope of EcoHeat

"EcoHit" is a soundproof wallpaper for walls in an apartment, Russian-made (LLC " Izhevsk plant plastics"), made from physically crosslinked Isolon 500 polyethylene foam and paper welded on both sides of it. Sandwich of paper layers ensures adhesion of the substrate to the wall and subsequent decorative trim. The manufacturer offers two sizes finished products:

Ecoheat wallpaper underlay 3 mm thick, roll length 14 m and width 0.75 m;
Ecoheat 5 mm thick - with a roll length of 14 m and a width of 0.5 m.

Leveling underlays of other formats or laminated with foil are intended for laying under parquet, laminated board or under the "warm floor" system. The main purpose of sticking rough wallpaper for walls is a soundproofing and insulating effect, which is ensured by the physical and mechanical properties of foamed polyethylene:

almost zero vapor permeability;
low (within 0.031–0.034 W/m °K) coefficient of thermal conductivity;
high rate noise reduction (specific value not specified).

Polyethylene foam properties

As additional benefits the manufacturer indicates the use of the material:

hygienic safety and environmental friendliness - polyethylene is indeed non-toxic and does not cause allergies;
simplicity and low cost of installation - "EcoHit" can be glued with a special glue for heavy wallpaper, and with the help of ordinary construction PVA;
versatility - the product fits under all types of wallpaper and is suitable for improving the heat, noise and vapor barrier of apartments, private houses and administrative buildings both under construction and renovation projects.

Externally, EcoHeat is a light, elastic, rolled material. white color. Its cost varies depending on the place of delivery and the volume of the order from 1100 to 1950 rubles per roll.

Penolon - characteristics and purpose

The manufacturer of soundproof wallpaper called "Penolon" offers a chemically cross-linked polymer, which has the following properties:

hygiene, elasticity and lightness;
resistance to aggressive environments - acid, alkali, alcohol, gasoline;
minimal residual deformation;
low vapor permeability and thermal conductivity.

Scope of Penolon

Purposes of application:

leveling of wall surfaces;
increase the level of noise reduction;
elimination of cold radiation from walls;
facilitation of gluing the finish;
solution to the problem of weeping walls.

In stores you can also see the Penofol building material - this is an analogue of the substrate for the Penolon wallpaper, reviews of which indicate that this is the same material. You can buy a standard roll for about 990 rubles.

Products of other brands

The range of soundproof wallpaper underlays is not limited to two brands. Other brands make similar products. To determine the differences, it is worth understanding the classification of polyethylene foam in general. So, there are three classes of this polymer:

gas-foamed non-crosslinked ("Teploflex", "Vilaterm", "Porilex", etc.);
chemically cross-linked ("Penolon", PoliFoam);
physically crosslinked (EtaFoam, HitFoum).

Non-crosslinked polyethylene foam is the cheapest material of the whole trio, since it is made using the simplest technology. Its strength and heat-insulating properties are 25% worse than those of polyethylene of a higher class. Therefore, do not be surprised by negative reviews - wallpaper for wallpaper made of non-crosslinked gas-foamed polyethylene does not give a clear result and does not last long.

Cross-linked polyethylene differs from non-crosslinked polyethylene by closed pores

Physically and chemically crosslinked materials, despite different technology production, almost identical in properties. When deciding which brand to give preference to, it is recommended to pay attention to the visible characteristics of the roll: color (should be uniformly white or light gray), strength of the paper to the base, no smell, elasticity (correctly, if after pressing with a finger the surface quickly restores its shape).

Advertising VS customer reviews

Manufacturers confidently declare that the sound and heat insulating effect of installing insulation for walls made of polyethylene foam under wallpaper in an apartment is comparable to the effect of laying bricks with a thickness of 125 mm (“half-brick”). Is this really so, you can find out by examining the reviews of real buyers:

Olga L., Saratov:

“My husband and I thought about warming the apartment in a cold panel house. Everything was decided external walls from the inside, glue the soundproofing substrate under the wallpaper. The sticker process was expectedly simple, but it took speed - the glue's response time was only 10 minutes (we took a repair and assembly acrylic compound). The result is not 100% satisfied, as it had to be replaced paper wallpaper non-woven (strange gaps formed between the paper ones). The rooms are a little warmer."

The material is well cut with a construction knife

Maria V., Moscow region, Ivanovo:

“I will share my impressions about the method of soundproofing in the apartment: I pasted a special substrate under the wallpaper, the inscription on which promised a significant reduction in the noise level. I bought and carried the material home myself, fortunately, the rolls have a convenient handle, and they weigh very little. I read the reviews and decided to glue the insulation on the PVA emulsion, strengthening the joints with masking tape - this is so that they do not diverge. From above, using ordinary wallpaper glue, I attached colored wallpaper. Now about the result: the substrate lived up to expectations - the neighbor's clatter behind the wall became quieter.

Oleg K., Ufa:

“In general, I recommend products like EcoHit or Penolon - the sound insulation from them is minimal, but they keep the heat and smooth the walls. I didn’t want to isolate my Khrushchev box with specialized methods and ended up sticking a polyethylene foam backing under the wallpaper. I was pleasantly pleased with the price and material consumption: for a room of 17.2 sq. m. took 2 rolls. After installation, it became more pleasant to be in the room, although the noise from the entrance (one wall borders it) is still distinguishable.

Competent installation of the substrate under the wallpaper

As can be seen from the reviews, the effectiveness of the heat and sound insulation of the wall in the apartment under the wallpaper largely depends on whether the substrate was glued correctly. This is echoed by the instructions that manufacturers usually attach to each roll. The installation algorithm for them consists of several steps:

Cleaning the wall from the old coating and removing loose plaster.
Repair of deep potholes and cracks.
Marking and cutting rolls into pieces desired length.
Applying wallpaper paste base surface and a substrate.
Sticking the substrate on the wall strictly vertically.
Complete drying of the base within 72 hours.
Gluing the lining according to the instructions for it.

Deep cracks and chips must be repaired

In addition to the sequence of actions, the microclimate conditions that must be maintained during the process are also specified: the air temperature is not lower than 10 ° C, the humidity is not more than 70% and the maximum absence of drafts. If you follow these rules, the manufacturer guarantees the service life of the insulation for 20-40 years, and it is allowed to remove the old wallpaper with plain water and stick new ones on the same substrate.

In many reviews, there is a complaint that, when dried, the joints of the wallpaper diverge and form unattractive seams. In order to prevent such an incident and to alleviate installation work, experienced craftsmen offer their own, "folk" instruction:

to stabilize the canvases and prevent the appearance of cold bridges, the joints can be glued with paper tape;
when gluing wallpaper on top of the substrate, it is better not to allow the joints of one and the other material to overlap each other;
do not wrap the backing sheets at the corners, but install them with a cut close to them;
at the slightest suspicion of a fungus, it is necessary to carry out appropriate processing.

It's time to draw final conclusions: it will not be possible to completely protect housing from noise pollution with the help of only a thin substrate. Acoustic engineers for this purpose develop soundproof structures with a thickness of at least 40–50 mm. On the other hand, few of the buyers for the sake of silence are ready to sacrifice the space that full-fledged soundproofing takes away.

As for heat retention, draft wallpapers do a good job with this function - at least it stops blowing cold from the walls. And finally, the last argument in favor of universal substrates is the quick and problem-free alignment of walls that have, however, small defects. So, if you want to get a predictable and long-term result after finishing the walls, it is still better to install a universal substrate for wallpaper.
