Types of sound-absorbing materials. Which material is best for soundproofing

Sleep badly and feel uncomfortable? Have you become annoyed for any reason? The best soundproofing materials for an apartment will help you cope with your problems and create the conditions for a good rest.

The reasons for poor sound insulation are:

• inadequacy of the construction of the house to the norms-standards;
• fencing failures. Voids and gaps reduce sound insulation;
• noise beyond measure in the apartments of neighbors or from the street from the outside.

Every owner of an apartment or house makes every effort to solve the inconvenience of everyday life and protect himself from unnecessary noise. Soundproofing is required to create comfortable living conditions, both in your home and to avoid conflicts. Active games for children, home theater, musical instruments - a partial list of objects and related activities for scandals.

To determine the choice of raw materials, it is necessary to establish the type of noise.

Distinguish:

• Air. Sounds transmitted from the outside by air: busy traffic, deafening music, industrial enterprises.
• Shock. Drilling walls, driving nails during repairs. However, specially designed insulation is necessary when carrying out systematic work using a jackhammer.
• Structural. The road transmits vibration to the walls of the apartment, converting it into decibels.

Attention! Noise from the motorway reaches 70 dB.
Soundproofing materials absorb sounds from the outside or prevent the spread from the apartment. It is required to find a suitable material for the interior of the room.

What to look for when choosing sound-absorbing material for your home?

When performing soundproofing work, the following should be taken into account:

• Room dimensions.

For small rooms - a children's room or a bedroom - a drywall sheet is suitable, which will not reduce the usable area. In spacious rooms, sound-absorbing multi-layer structures are installed in a special frame, which occupy a lot of space. Styrene, mineral wool or kraft cardboard.

• The purpose of the room.

Materials suitable for the bedroom should not be used in the kitchen, which is characterized by high humidity and temperature fluctuations. Select stable insulating materials.

• Invoice.

Its use in monolithic concrete houses differs from frame buildings. The quality of sound insulators depends on the price.

• Invoice quote.

It is required not only to correctly combine sound insulators and soundproofing materials, but also to take into account their qualitative properties. The purpose of the texture is the interior decoration of premises, therefore substances harmful to health are excluded from the composition: bitumen and lead, mercury and formaldehydes, volatile resins, EPDM compounds and volatile resins.

• Sealing joints and cracks.

The structures require integrity and solidity. Therefore, eliminate all unnecessary holes and holes. Unsealed connection, uninsulated air pipes, risers and sockets reduce sound insulation. Sealing joints with soft mastic or sealant.

• Qualified installation.

To achieve an effective result, competent mounting is required. Qualified workers in soundproofing, repair and decoration will come to the rescue. It is important that soundproofing based on design ideas matches the interior inside the apartment or house and does not interfere with engineering communications.

Distinguish:

• stretch ceiling made of film or fabric, which is installed on pre-fortified brackets;
• false plasterboard ceiling. Mineral wool or other soundproofing material is placed in a metal frame attached to the ceiling;
• suspended ceiling. When installing the frame, soundproof fillers are used: cork, polyurethane foam blocks, coconut fibers, basalt wool cork. Closed with panels.

Practical video tips on installing ceiling soundproofing with your own hands:

Wall soundproofing

Before work, they inspect the wall and close up cracks and cracks. The fastest and most convenient way is to rub with cement. Pull out electrical outlets and check for voids. If necessary, lay with mineral wool, seal the hole with putty or cement before putting the outlet in place.

Soundproofing material and installation methods are selected according to the price, efficiency and quality of sound insulators, as well as the footage of the “eaten up” usable space.

A variety of textures are used for decorative soundproofing of walls. The construction services market provides a wide range of products. Are especially popular with consumers:

• drywall;
• soundproof panels;
• roll material.

Video instruction for working with spare parts panels for soundproofing walls:

Drywall installation

Assemble the frame. If the walls are thin, fix the profile on a rubber lining. Mineral wool or other material as a noise absorber is embedded in the prepared crate. The structure is covered with plasterboard sheets. Shpatlyuyut, finishing.

Assembling the soundproofing panel

With a perfectly even coating, the panel is installed immediately on the wall. Fastening thanks to the notch-protrusion lock or using construction adhesive. The problem of leveling the wall covering is solved in two ways: by assembling the frame, as is the case with mounting drywall or putty.

The panel installation is quite simple. No finishing required as surface coating is available. A variety of materials and colors: paper tapestries, fabric, wood or stone lamination.

Pasting of roll noise insulators

Save money and time. Convenient to use. Glue is used for dense vinyl or non-woven wallpaper. The work is not very difficult, the result is good for an inexpensive material. Rolled sound insulators cope with 60% of noise.

Sound insulation for partitions

As a rule, sheathing is used in two or three layers. Installation is carried out in various variations: drywall, plywood, glass-magnesite or gypsum-fiber sheet. The construction of 2 layers of plasterboard sheets with a sheet of gypsum fiber has not only massiveness, but also positive resonant properties. Vertical fastening of sheets with screws at a distance of 25 cm, so that the layers are connected with a shift. The joining of the plates is sealed with putty or silicone sealant.

Peace and quiet - every resident of an apartment building or a house located near a noisy highway dreams of this. Fortunately, soundproofing materials, combined with their proper use, will help get rid of all kinds of noise. This will be discussed - how to properly apply soundproofing.

Often, by noise, many people mean only one type of sound - air. These are the sounds that come to us from the outside: passing cars, screams of children in the yard, barking dogs, a construction site nearby. However, there is also an impact type of noise (hammering nails into the wall, the notorious drilling in the neighborhood, rearranging furniture) and structural noise - in this case, the sounds are transmitted directly through the building structure, the elements of which are joined rigidly and without the use of soundproofing pads.

A person feels comfortable with sound vibrations within the limit of 25 decibels., although sanitary standards somewhat overestimate this rate - up to 30 dB at night and up to 40 dB during the day. Of course, each person has his own standards of perception - someone calmly endures all 60 dB, but more decibels can make you seriously nervous.

For this, soundproofing was invented - its task is to reflect noise, not to allow them to pass through walls and other obstacles into your environment. Good for those who have thick walls - by themselves they perfectly reflect sound vibrations. However, this hardly applies to most panel houses and new buildings. In addition to sound insulation, there is also sound absorption - the ability of materials to absorb sound waves. Most granular, fibrous or cellular materials just have this ability.

Among such materials, soft, semi-rigid and hard are distinguished. Soft sound absorbers are made of fiberglass or mineral wool, as well as felt and ordinary wool. These include pumice and vermiculite - the so-called porous aggregates. Semi-rigid materials include plates made of the same fiberglass or mineral wool, as well as materials with a cellular structure, for example, polyurethane foam. By the way, their sound absorption coefficient is slightly higher than that of soft ones, but their specific gravity is greater.

Airborne noise is the easiest to deal with - porous and fibrous materials that can be mounted both outside and inside the building are saved from it. In addition, they have another property - thermal insulation, so their use is doubly beneficial. Impact noise can also be "plugged" with closed-cell materials by laying them around the perimeter of walls and ceilings. But structural noise is a more significant problem, because the materials must be laid at the construction stage.

For noise insulation of structural noise, it is recommended to use soundproof panels as the main element in the construction of structures. The panels are produced under different brands, such as FonStar, Sonoplat, Tycho, SoundGuard and others. The choice is yours. We can only recommend Ticho Group products in terms of price-quality ratio. .

Vibroacoustic sealant is used when filling joints in the construction of floating floors, cladding and frame partitions. The material provides a high degree of vibration isolation, does not cause metal corrosion, has good adhesion to most building materials such as brick, concrete, ceramics, wood. The cured sealant is odorless, but when working with it, ensure good ventilation of the premises and avoid contact with skin and eyes.

Silica fiber gaskets are a lesser known material used for soundproofing rooms with high fire safety requirements. This material is safe for humans and non-flammable. It is important to note that the presence of one type of sound insulation does not guarantee peace and quiet in your house or apartment - you need to skillfully arrange these materials in order to achieve a really significant effect.

For protective materials of this kind, such an indicator as the sound insulation index, measured in dB, is characteristic. The second indicator is the degree of sound absorption, which is measured from 0 to 1. The closer this degree is to one, the better the material. As already mentioned, thick walls themselves protect the comfort of our home from extraneous sounds. However, to increase the massiveness of walls and ceilings is a task too difficult for the layman, and inefficient.

The most acceptable way of soundproofing in this case is to create a multilayer structure from hard, cellular and soft materials, which can be done with your own hands from popular building materials.

In most cases, drywall acts as a rigid material - its thickness is optimal for interior work, when it is important to preserve as much living space as possible. Drywall acts as a soundproofing material, while a layer of soft material takes on sound absorption. As already mentioned, these include glass wool, mineral wool, polyurethane foam and other cellular formations. For effective sound absorption, the layer of material in a multilayer structure must be at least 50 mm and make up at least half of the entire structure.

The task of soundproofing floors, as well as in the house, is performed by an acoustic ceiling - also a multilayer structure that reduces the energy of sound vibrations and absorbs them. This requires the formation of an air space between the floor and the ceiling area - it is filled with pressed mineral or fiberglass boards.

After all, there is a cheaper polyethylene foam! Quite often, laminate flooring manufacturers offer it along with their products. Polyethylene foam is used both for soundproofing floor coverings and floating floors, and for sealing joints. It is resistant to almost all solvents, it is in good contact with cement and other finishing materials. However, when wetting the space filled with polyethylene foam, good conditions are created for mold colonies. In addition, prolonged loads lead to a loss of material thickness (up to ¾ of the original value), which in turn leads to a loss of soundproofing properties.

The composite material, consisting of two layers of polyethylene film and expanded polystyrene beads, is an improved version of the use of polyethylene. The top layer provides protection against moisture penetration into the structure. The lower film lets air and steam into the space between the films, but from there they are removed through the seams. Such ventilation prevents the accumulation of moisture and mold. The composite material does not deform and serves for a long time - from 20 years. When laying, the use of adhesives is not required.

The cork-rubber backing consists of cork and rubber granules. This material perfectly dampens the vibration of household appliances and other appliances. It is effective to lay such a substrate both under elastic and hard floor coverings: linoleum, parquet, laminate, tile. However, the cork-rubber coating needs additional protection from moisture, since it serves as a medium for the emergence and development of mold.

Constant noise is an obligatory companion of residents of large cities. Some people get used to banging doors, overhead steps and working TVs behind the bedroom wall, but most citizens try to protect themselves from too aggressive acoustics by installing a soundproofing system in their apartments. Modern soundproofing materials for houses and apartments allow you to counteract almost all types of noise: airborne, shock and structural.

Peculiarities

It is not the presence of noise as such that brings discomfort to a person, but the excess of permissible sound power values. With a noise of 25-30 dB, the human body feels most comfortable, as sound stimuli increase, the attitude towards noise changes to tolerant, which it remains until the power reaches 60 dB. When this index is exceeded, noise becomes an aggressive irritant that can significantly affect the state of the psyche.

In modern cities, noise can have a different nature:

• Airborne noise includes barking dogs, voices, medium and high frequencies of music, the noise of cars, etc.
• Impact noise includes low frequencies of music (subwoofer), furniture rearrangement, indoor walking, hammer drills and other construction tools.
• Structural noise is a mix of the above noises, which is the transmission of vibrations from all types of sound effects through the structures of buildings.
• Acoustic noise occurs in half-empty rooms, this is a familiar echo for everyone.

Accordingly, for protection against each type of noise, soundproofing materials with certain physical characteristics are required: sound absorption and sound insulation.

One of the most important is the sound absorption coefficient, which is determined on the basis of acoustic tests carried out for each building material. The maximum is 100% sound absorption, which is characterized by a coefficient value of 1. This indicator is directly related to the degree of density and allows us to distinguish the following categories:

• Solid materials, which include granulated or suspended mineral wool, as well as vermiculite, perlite or pumice. These materials have an average absorption coefficient of 0.5 and a fairly high bulk density of approximately 400 kg/m3.
• Semi-rigid: mineral or glass wool boards, as well as materials with a cellular structure, such as polyurethane foam, etc. The sound absorption coefficient varies between 0.5-0.75, the mass can be from 80 to 130 kg / m3, depending from variety.
• Felt, fiberglass and mineral wools, not pressed in the form of plates, are considered soft. They have a high absorption coefficient - 0.7-0.95 with a bulk density within 70 kg/m3.

In order to successfully deal with noise, it is also necessary to take into account such an indicator as the sound insulation index of the material. It is measured in the same value as noise - in decibels (db) and calculated for each type of building materials: concrete, plasterboard, brick, foam blocks, mineral wool, etc. A monolithic floor slab, which has a thickness of at least 200 mm, has a sound insulation index 74 db. For a new brick wall with a thickness of half a brick (150 mm), the maximum index is 47 dB, which decreases over time due to the appearance of cracks and cracks.

To prevent the audibility of human speech, the wall must have a sound insulation index of at least 50 dB. Accordingly, thin walls in panel houses that do not satisfy this indicator must be further strengthened.

You can do this in several ways:

• build additional dense and massive walls or ceilings, for example, from foam blocks, while maintaining maximum tightness;
• create a multi-layer structure from several soundproofing materials, alternating soft and hard types for maximum suppression of all types of noise and observing the rules of tightness;
• use ready-made soundproof panels made of materials of various densities and structures and designed for a wide frequency range of sound waves.

Due to the fact that the arrangement of powerful walls / partitions made of brick or concrete requires a corresponding foundation capacity, these indicators must be included in architectural calculations at the stage of drawing up construction and design documentation.

In cases where it is necessary to enhance the soundproofing qualities of an already built wall or to erect soundproofing partitions in an apartment, either ready-made soundproofing panels are used, or prefabricated structures made of various modern materials are mounted directly on site.

Varieties

Modern varieties of materials for sound insulation are usually considered in terms of resistance to a particular type of noise.

Materials that successfully resist impact noise are called sound repellent because they do not absorb but repel sound waves. Most often, such materials are used in the construction of "floating floors" as a substrate.

Modern industry provides a huge selection of insulating substrates:

• Staple fiberglass. The material belongs to the class of durable, has a high impact noise reduction index - 42 dB, non-flammable. This category includes such material as "Shumostop - C2".
• The membrane is polymer-bitumen. The base is a soundproofing layer made of non-woven polyethylene, on the surface of which a coating of bitumen with plasticizers-polymers, reinforced with glass fiber, is applied. The material is resistant to decomposition and rotting, vapor-permeable, has an impact noise reduction index of 26-39 dB (depending on thickness). Combustibility group - G2. FonoStop Duo and Izolonteip can serve as a striking example.
• Fiberglass canvas with one-sided bituminous impregnation. Designed for long service life, waterproof and fire resistant material. Noise reduction index - within 23-29 dB. This variety includes fiberglass brand "Shumanet", as well as "Isofon-super".

• Extruded polystyrene foam. This is a durable material (designed for 50 years), which has a noise reduction index of 25 dB, is characterized by low water absorption and high compressive strength, a minus can be called a high fire hazard index - G1. These are brands such as Fombord, Penoplex, TISplex plates, etc.
• Composite. This material consists of three layers: between the layers of polyethylene or aluminum film there are polystyrene foam granules. The peculiarity of the composite is that the lower film has the ability to pass moisture into the interior, from where it is removed through expansion joints. Thus, the space is ventilated. The service life is 20 years, the noise reduction index is in the range of 18-20 dB, the material is not combustible. These are such brands as Tuplex, TermoZvukoIzol, Vibrofilter.
• Cork rubber backing. These are mats made of rubber granulate and cork chips. The material has an average fire safety (combustion class B2), however, it can contribute to the appearance of mold in structures, and therefore requires additional waterproofing. Noise reduction index - from 18 to 21 dB. These are materials such as UZIN RR 188, Utsin RR 188, Ibola.

• Cork underlay. The material, which is produced from pressed cork chips, is not subject to rotting and fungus, the service life reaches 40 years. Reduces impact noise by 12 dB. An example is Cork Roll, Corksribas, Ipocork, etc.
• Polyester foam. Synthetic fiber material, impregnated on both sides with a reinforcing fiberglass composition, has a high vapor permeability, allowing the surfaces to "breathe", the sound insulation index is 8-10 dB. Flammable (class G2).
• Polyethylene foam ( foam polyethylene). There are non-crosslinked polyethylene foam, which has the least soundproofing effect; physically cross-linked and chemically cross-linked, the soundproofing quality of the latter variety is the highest. The material has a high flammability class - G2, is destroyed when exposed to ultraviolet radiation, sags under prolonged loads, and is resistant to mold. The sound insulation index varies from 12 to 15 dB. These are brands such as Isopenol, Pleneks, Izolon and many others.
• Tecsound. Thin synthetic material on an elastic polymer base, used to isolate two types of noise: air and vibration (shock). It is a self-extinguishing and moisture-resistant material, has a sound insulation index in the range of 25-30 dB. Effective in suppressing noise from a metal roof.

Separately, it is worth considering materials that dampen impact noise and are used for the installation of acoustic ceilings:

• Perforated sound-absorbing Knauf plates. This is a drywall-based material, on one side having a synthetic fabric backing with resonator holes. Thickness 8.5 mm, fire hazard class - NG. As test tests show, these plates are designed to extinguish low-frequency waves.
• Plates "Ecofon", which are a "sandwich" of high strength fiberglass, additionally reinforced with a mesh of textiles. Available in thicknesses from 15 to 40 mm, non-flammable.

In the event that airborne noise is primarily a concern, it is worthwhile to identify gaps and cracks in the wall structure and eliminate them. If, having ensured the maximum possible tightness of the existing wall, it is not possible to achieve the desired effect, it is necessary to create additional sound insulation.

Modern sound-absorbing materials:

• Mineral (basalt) wool. This material is the result of the remelting of rocks of the basalt group, metallurgical slags, as well as their mixtures. Produced in the form of plates (mats). Having a fibrous structure and a short fiber length (15 mm), mineral wool provides a high absorption coefficient of sound waves - from 0.87 to 0.95; It has good vapor permeability and belongs to non-combustible, inert and biologically passive building materials. The following brands are most popular: Rockwool "Acoustic Butts", "Shumanet", "Izolight", "Basaltin", "TermozvukoIzol".

• Glass wool. Material based on glass fiber (average fiber size is 50 mm), having a sound absorption coefficient of 0.85 to 1 (for the Knauf "Insulation" acoustic partition, which is distinguished by a special combination of fiber lengths). It is produced in the form of plates, non-combustible, vapor-permeable, biologically and chemically inert. Compared to mineral wool, glass wool is lighter in weight. In the Russian Federation, such varieties as "Knauf Insulation", Ursa "Pureone 34 PN", Isover, etc. are presented.

• ZIPS(soundproof sandwich panels). These are frameless systems that can be purchased ready-made, effective against all types of noise. The composition is usually the same: GVL + fiberglass (mineral wool) + attachment points to the wall. These systems have a high sound insulation index, which largely depends on the thickness of the structure (ZIPS can be from 40 to 130 mm in size). When using a panel with a thickness of 70 mm, this is 10 dB. At the same time, the panel also has a high sound absorption coefficient due to the presence of mineral wool or glass wool inside. The disadvantage can be called a significant weight, requiring partitions with high bearing capacity.

The next type of soundproofing materials are those that "work" against the spread of structural noise. They are gaskets or compounds used during the installation of adjacent structures: ZIPS systems, wooden or "floating floors", frame partitions and claddings. Among them:

• Fiberglass. Produced from superfine fiber in the form of tape strips of various widths. It has a high impact noise reduction index - 29 dB. An example is such material as "Vibrostek M" or "Vibrostek V300", as well as stitched fiberglass mats "MTP-AS-30/50".
• Vibroacoustic sealant. Most often it has a silicone base, it can be both non-hardening and hardening. It has excellent adhesion to all types of building materials; when filling joints, it reduces the spread of structural noise. The following brands are most familiar to the domestic buyer: Green Glue, Vibrosil, Bostik 3070, Silomer, as well as vibration-absorbing mastic.

• Self-adhesive elastomeric gaskets for doors and windows. They are produced from porous rubber, microporous polyurethane, etc. in the form of plates or tapes, they are installed between structural elements and along the perimeter of openings to reduce vibration, they have a noise reduction index within 23 dB. As an example, we can name such brands as Varnamo, ArmaSound. Recently, similar materials have been actively produced by Russian enterprises, for example, Obninsgazpolimer LLC.
• Silica fibre. This material is the most fireproof, while having a high noise insulation index - 27 dB. Available in mats and rolls. The following brands are most popular: Vibrosil-K, Supersil, Ekowoo.

Scope of application

The properties of soundproofing materials have the widest range of applications. Most of them are used not only for their intended purpose, but also as a heater. Basically, this applies to all types of mineral wool, glass wool, fiberglass, polyester foam, sandwich panels and cork substrates.

How exactly to use this or that soundproofing material so that it “works” as fully as possible should be decided by a professional who is able to correctly assess the acoustic features and problems of a particular room. Perhaps the room needs sound-absorbing flooring to avoid conflicts with downstairs neighbors, or the walls need to be completely insulated when setting up a home theater. It may be necessary to shield the bedroom from the noise coming from the street.

Therefore, it is recommended to seek advice from a construction and repair company dealing with soundproofing issues at a professional level, because it is easier to pay for the services of a competent expert assessment than to invest in repairs without being sure of the final result.

The greatest effect can be obtained by integrating one or another material into building structures directly during the construction of buildings, the construction of floors, walls and partitions:

• when laying mineral wool slabs in the cavity of partitions;
• by installing plates or tape gaskets between elements of building structures to absorb structural noise;
• when installing soundproof panels on the surface of the walls with their subsequent plastering;
• when arranging "floating floors", at the base of which there is a soundproofing material, followed by the installation of a reinforced cement-sand screed.

To improve sound insulation in already constructed premises, the following methods are used:

• Creation of a sound-proof layer on the surface of interfloor ceilings by placing mineral wool mats (glass wool) covered with either cement or prefabricated screed.
• Installation of soundproof frame structures, which is an alternation of plasterboard, mineral wool or glass wool slabs, as well as a superdiffusion membrane (if necessary), damper tape and vibroacoustic sealant.

• Placing soundproof sandwich panels on the walls. These are frameless systems that are sold ready-made. They usually consist of GVL sheets, between which there is fiberglass (mineral wool) and mounted nodes for attachment to load-bearing walls. The sealing of the structure is carried out by means of damper gaskets and sealant.
• Arrangement of "acoustic ceilings", which are mounted on a frame made of galvanized metal profiles. The structure consists of drywall sheets and mineral wool slabs and is fixed on vibration-isolating hangers. For sealing, gaskets are used in combination with vibrosealant. It is also worth considering the possibility of installing stretch ceilings with soundproofing effect.
• Installation of a “ventilated facade”, which is carried out on the outer wall of the building and additionally performs a heat-saving function.

How to choose?

The choice of any building material must be approached rationally. This fully applies to noise-absorbing materials, the properties of which should correspond as much as possible to the tasks that need to be solved. At the same time, it is desirable that the cost of the work does not "strain" the owner's wallet unnecessarily.

When arranging soundproofing, you should either trust a time-tested (and reviews of friends) repair company, or study the issue yourself or follow the recommendations of sales consultants. You can save money with each of these options.

Advantages of contacting a construction and repair company:

• an assessment of the problem and ways to eliminate it is carried out by a repairman (foreman), who recommends certain soundproofing materials;
• serious repair companies give a guarantee for the work performed (usually 3 years), therefore they offer materials and technologies that they are confident in;
• when contacting the company at that time of the year, which is not considered the construction season (late autumn, winter, early spring), the customer is offered a discount on the cost of work;
• large firms usually have trusted suppliers who often sell materials to customers at a discount.

Advantages of self-selection of materials and work:

• in the process of studying the issue, useful knowledge is acquired that may be useful in the future;
• the buyer saves a significant amount on the payment of workers;
• you can spend the money saved on the use of more expensive soundproofing materials.

Analyzing the problem of noise on your own, it is worth finding out what its nature is and whether it is airborne or impact noise.

These types of noise can be eliminated in almost any room and at any stage of repair / construction, in contrast to structural noise, which must be isolated from at the stage of building construction.

Most often in residential premises there are noises of both types. For example, in the apartment below there is an office, whose visitors are constantly slamming doors and talking. In this case, we can talk about the totality of all three types of noise, which can be extinguished with the help of soundproofing the floor, including the use of two types of material - noise-absorbing and noise-repellent, with the obligatory use of damper pads, which can partially extinguish structural noise. This provides for the installation of acoustic "floating floors" with a layer of mineral wool at the base of at least 100 mm and a mandatory powerful screed on the surface.

Soundproofing "cardboard" walls is usually required to protect against airborne noise. This issue is solved through the use of frame or frameless systems made of plasterboard and mineral wool, the thickness of which is the greater, the stronger the sounds disturbing the residents. In the event that music is heard from behind the walls, noise-repellent material, such as extruded polystyrene foam or staple fiberglass, should also be added to the structure.

You can also enhance the effect by increasing the layers of GCR. In the case of using factory-made ZIPS, it is necessary to select a brand with high noise-repellent characteristics. Such structures have significant weight, so you need to make sure in advance that the walls are able to withstand such a load.

For a wooden house, materials are used that have the lowest flammability class (NG), resist the appearance of mold and fungus, are resistant to rodent attacks and, of course, vapor-permeable.

How to do it yourself?

It must be understood that the acquisition of even the best soundproofing materials in itself will not ensure silence in the room if the technology of their installation is violated. Achieving this goal will require proper installation, which acoustic professionals can provide. In the event that for some reason it is impossible to contact a construction company, you should carefully study the recommendations in order to carry out soundproofing work with your own hands. The use of improvised means as an insulating material, most likely, will not give the desired result.

For the correct installation of soundproof cladding, exactly those materials are needed that are provided by the technology.

Necessary materials:

• guide and rack galvanized profile, which can replace wooden bars;
• suspensions (preferably the use of vibration suspensions);
• self-tapping screws, which for better soundproofing of structural noise should be equipped with rubber washers;
• damper pads in the form of a tape;
• vibroacoustic sealant;
• GKL or GVL sheets 12.5 mm thick;
• fiber boards: mineral wool, glass wool, having a thickness of 50 mm.

The soundproofing of walls "at a distance" will take from 50 to 120 mm of free space, which will have to be sacrificed in order to obtain acoustic comfort.

The sequence of work on the installation of structures of soundproof frame-sheathing partitions:

• Installation of a cushioning (damper) tape with a thickness of at least 4 mm along the contour of the mounted partitions. Gaskets are glued to the walls, floor and ceiling with a sealant.
• The frame is mounted according to the level, the guide profiles are set at a distance of at least 10 mm from the surface of the insulated walls.
• Rack profiles are mounted in increments of 600 mm, their length should be 10 mm less than the height of the room.
• Vertical posts intended for a doorway must be strengthened by locking two elements of the rack profile; it is possible to use wooden bars for these purposes.

• The internal space in the rack profiles is filled with mineral wool or glass wool slabs, while the slabs must be inserted as tightly as possible to avoid gaps.
• The frame is sheathed with GKL sheets with a step of 500 mm. In the case when 2 or 3 layers of sheathing are mounted, it is recommended to choose a GVL sheet that is more resistant to loads for the primary layer. Finishing facing is mounted with a step of 200-250 mm.
• A technological gap is left between the sheathing sheets and the ceiling / floor, which is filled with vibrosealant.
• Excess damper tape is trimmed flush with the finish layer of GKL sheets.
• When installing the door, the joints between the frame and the door frame are filled with sealant, a sealing tape must be installed on the surface of the frame at the points of contact with the door leaf.

The implementation of soundproofing the ceiling requires sufficient height in the room, since the structure occupies approximately 120 mm from the height of the room. Stages of work:

• A damper tape is glued to the surface of the walls adjacent to the ceiling.
• A guide profile is temporarily fixed along the perimeter of the walls with dowel-nails.
• Vibration-isolating suspensions are attached to the ceiling surface, the pitch is 800-900 mm. From the wall to the first suspension should be no more than 150 mm.
• Supporting profiles of the frame are fixed to the suspensions, the distance between which should not exceed 600 mm.
• Secondary profiles are mounted on the profiles of the first level, providing an air gap between the floor slabs and the insulating material.
• The dowel-nails holding the guide profile are removed (this is done to avoid the appearance of noise bridges).

• Sound-absorbing plates are installed in the frame.
• The first layer of ceiling sheathing is being carried out, while GVL sheets 10 mm thick are used.
• Seams between sheets are filled with vibroacoustic sealant.
• A second layer of sheathing is installed using GKL, which is mounted with a gap in the joints.
• Excess damper tape is cut with a construction knife, the seams are filled with sealant.

When installing floor soundproofing, several different technologies can be applied, depending on the materials used. The most popular technologies are "floating floors" Rockwool and the method of the company "Acoustic Group", based on the use of "Shumostop" plates.

Noise isolation of the floor (according to the Noise Stop system):

• The surface of the floors is being prepared: irregularities are smoothed out, construction debris is removed, adjacent communications are isolated using elastic gaskets or tape.
• Slab soundproofing material of the Shumostop brand is laid along the perimeter of the walls to prevent contact between the leveling screed and the building envelope. The height of the edge should slightly exceed the thickness of the screed. It is acceptable to use a damper tape to minimize the thickness of the seam between the screed and the wall.
• A layer of denser material is laid out around the perimeter of the room - this is Noise Stop K2.
• The floor surface is covered with the main working material - "Shumostop C2". Laying is done as tightly as possible, without cracks and gaps.

• The surface is covered with a reinforced polyethylene film, which is also lifted along the wall to the height of the edge. The joints are overlapped and glued with tape.
• A solution of a sand-concrete mixture of grade not lower than M-300 is laid out on the film, which is then reinforced with a reinforcing mesh (fragments of the mesh are necessarily fixed to each other).
• A concrete solution is poured over the grid, which is leveled using a plaster rule.
• After the screed has gained strength (on average, it takes 28 days to dry), the edge layer of the film and the damper strip are cut to the level of the screed.
• The resulting seam between the wall and the screed is filled with a vibroacoustic sealant.

It makes no sense to take a word for such statements, all the more unreasonable to check fashionable innovations on your own experience, since the cost of such soundproofing materials is usually quite high.

• If the dimensions of the room allow, then it is better to use a frame soundproofing system as having the largest number of positive reviews.
• In the case when frame-sheathed partitions are being built in the room, you can also worry about soundproofing equipment in advance: in this case, mineral wool slabs are mounted inside the partition and do not take up additional space.
• In cases where it is required to save the area or height of the room as much as possible, it is worth using ultra-thin materials from trusted manufacturers, for example, Rockwoll "Acoustic Butts Ultra-thin" or ZIPS ultra-thin sandwich panels.

• When carrying out work, it is necessary to achieve maximum tightness of structures, which will prevent both the appearance of sound bridges and the ingress of the smallest dust particles of mineral wool or fiberglass into the respiratory system.
• To fix vibration suspensions to the ceiling, it is desirable to use a special type of fastener - an anchor wedge with a plastic nozzle.
• When connecting communications, they must be tied with a sealing tape in order to avoid the preservation of the so-called "sound bridges".
• In wooden buildings, it is not recommended to erect soundproof partitions earlier than a year after the construction of the building. This is due to the process of primary shrinkage at home, during which it is not advisable to carry out work.

When purchasing materials through online stores, you should not start from the rating, it is better to compare the characteristics given in the tables that are present on the pages of all major trading platforms.

Soundproofing residential premises is becoming more and more important every year. And every homeowner wants to choose the best soundproofing material that protects from outside noise. Although it is difficult to choose them according to the “bad-good” principle, since many of them have a specific purpose and, to one degree or another, perform the assigned tasks.

So what is soundproofing? As a rule, noise and sound insulation is a complex multilayer structure, which includes dense layers that reflect sound waves and soft layers that absorb extraneous sounds.

In this regard, neither mineral wool, nor membrane, nor panel materials should be used as independent sound insulation.

At the same time, it is a mistake to assume that heat insulators (cork, PPS, PPE, etc.) are able to fully fulfill the role of noise protection. They are not able to stop creating a barrier against the penetration of structure-borne noise.

Even worse, if you stick sheets of polyurethane foam or polystyrene on the wall under the plaster, then this design will increase the resonance of the incoming noise.

Overview of the best soundproofing materials

Rock Wool Acoustic Butts

Rockwool Acoustic Butts, a group of companies that have been producing basalt fiber boards for eighty years, can be put in first place.

Stone wool pressed into panels has found its application both in residential and industrial construction as a heat and sound insulator.

Benefits of Rockwool Acoustic Butts:

• High sound absorption class (A / B depending on the thickness), excellent sound absorption ability: air vibrations up to 60 dB, shock - from 38.
• Low thermal conductivity and complete fire safety.
• Vapor permeability, moisture resistance, biostability, durability.
• Certification according to the norms of the Russian Federation and the EU.
• Ease of installation.

Disadvantages:

There is a risk of acquiring a fake.

High cost, to a large extent caused by the need to use additional components and waste accounting.

Soundproof

These are bitumen-polymer sound-insulating membrane-type materials based on modified resins, which have sound, heat and waterproofing qualities.

Applicable for walls, ceilings and floors, including for "warm" on the floating system. Included in category G1 - low flammable.

Positive properties:

• Versatility, durability, affordable price.
• Water-, bio- and temperature resistance (-40/+80°С).
• Low degree of thermal conductivity in accordance with SNiP 23-02-2003.
• Sound protection for airborne noise up to 28 dB, for shock - up to 23.

Negative:

• A small dealer network in the Russian Federation.
• The elements have considerable weight, and therefore they cannot be called the best option for weak load-bearing bases.
• Only one mounting method is allowed - adhesive.

Tecsound

The company is engaged in the production of polymer-mineral membrane soundproofing materials. These are flexible elastic roll products, very dense, for which they were classified as heavy.

• Versatility due to stretch property.
• Certification according to Russian and European standards.
• Environmental safety due to the absence of phenol-containing substances.
• Airborne noise reduction up to 28 dB.

Disadvantages:

• Possibility of installation - only glue.
• It is not applicable as an independent material for soundproofing.

The cost is above average.

Shumanet

Mineral wool boards of the Shumanet series are designed for wall and ceiling frame soundproofing systems for subsequent finishing with facing materials (plywood, plasterboard or fiber sheets, chipboard).

• Resistance to moisture, the formation of mold and fungus, durability.
• Excellent vapor permeability and minimal thermal conductivity.
• Full fire safety and incombustibility - classes KM0 and NG.
• Compliance with high sound absorption classes - A / B at any frequency, reduction of noise waves of structural and air type from 35 dB.
• RF certification.
• Ease of installation, due to the property of elasticity.

Disadvantages:

An increased degree of phenol emission (slightly exceeds the permissible), that is, environmental friendliness is in question.

The high cost caused by the need to purchase many additional. elements, the need to strictly follow the installation instructions.

ZIPS panels

The panel system from the manufacturer "Acoustic Group" appeared at the very end of the last century. This is a multi-layer structure, whose composition varies depending on the purpose.

For ceiling and wall surfaces, tongue-and-groove gypsum plasterboard sheets are used as the base, for floor surfaces - gypsum fiber ones. They are supplemented with fiberglass or basalt slabs.

To a large extent, vibrating units made of polymer and silicone prevent the transmission of vibration and noise waves. Degree of combustibility G1 (low combustible).

Advantages:

• Durability, efficiency and biostability.
• Little thermal conductivity.
• The absence of inter-plate gaps during installation, provided by the tongue-and-groove type of connection.
• No need to use adapters when fixing plates.
• Compliance with GOST requirements.

Disadvantages:

When wall mounted, the plates can resonate by 2-3 dB with incoming-outgoing low-frequency noise up to 100 Hz.

During installation, many components are required, which significantly increases the final cost of installation.

Plates SoundGuard (SoundGuard)

A fairly effective product, attractive at a democratic cost, produced by an alliance of experienced manufacturers, known on the Russian market for several years. Prefabricated noise protection structure includes:

• Drywall Volma,
• Profiled SoundGuard board (consists of mineral-quartz-filled gypsum board and cardboard cellulose panel),
• frame profile.

According to the degree of flammability, they belong to the group G2 (moderately flammable), toxicity T1 (low). Among the advantages of the SaunGuard panels are:

Compliance with all safety requirements and certification of the Russian Federation.

Versatility - the plates are applicable to any wall and floor bases.

Minimum thermal conductivity.

Good sound insulation performance (airborne noise - up to 60 dB, shock - up to 36).

Ease of installation, the ability to choose the installation method (adhesive, frame, using plastic dowels).

Of the shortcomings:

• Lack of moisture resistance property.
• Few sales representatives in Russia.
• High prices.
• In the process of cutting, shedding of the mineral filler occurs. This makes it necessary to process the edges of all plates with tape or tape.

In addition, if the panels are used as an independent sound insulator, then the degree of obstruction to impact and air-type noise does not exceed 7 dB. Like ZIPS, panels can resonate with low frequency noise.

Noise insulation of walls in an apartment, modern materials for which today can be found in hardware stores, is becoming more and more relevant. This is explained simply - fences in multi-storey typical houses are not able to fully protect the home from external street noise and from sounds coming from neighboring apartments.

medical scientists It has long been noted that the presence of constant noise has an extremely negative effect on the human psyche, not allowing him to get complete relaxation and rest. That is why, unable to withstand the constant sound pressure, many city residents, especially those who live in panel houses, begin an active search for a suitable soundproof material that will meet all the requirements for its use in apartments.

Almost all modern acoustic materials are made on the same basic principles as traditional ones. However, they have undergone significant improvement due to recent production technologies.

To date, a very large number of new soundproof materials are being produced, and it is simply impossible to cover the characteristics of all on the scale of one article. Therefore, attention will be focused on the most effective ones, which are used in an apartment.

Thin soundproofing MaxForteSound PRO

When the area of ​​​​an apartment or room does not limit the choice of materials, and you can install sound insulation of any thickness, this is convenient. But what if you can't afford to spend precious inches of living space?

In this case, the innovative MaxForte SoundPRO thin soundproofing material will suit you. It has a thickness of only 12 mm, while in terms of its characteristics it is able to compete with sound insulation with a thickness of 5 and even 10 cm! MaxForte SoundPRO is the latest material designed specifically for soundproofing residential and industrial premises.

Specialists from the Research Institute of Building Physics and the Department of Acoustics of the Faculty of Physics of Moscow State University took part in the development of the material. In the manufacture of MaxForte SoundPRO, all the important points for the effective operation of the material were taken into account: the optimal density was selected (with a low density, the sound will pass through, if it is too high - along the "skeleton"), the length of the fibers, their thickness. The sound-absorbing layer is calibrated and uniform over the entire area. The material is completely non-flammable. The composition does not contain harmful phenol-formaldehyde resins and any adhesives. Therefore, in addition to excellent soundproofing properties, MaxForte SoundPRO is safe for health.

MaxForte SoundPRO gives an increase in sound insulation from both air (loud TV, a crying child, screams of neighbors) and impact noise (noise from trampling, grinding furniture, falling objects). It can be used for soundproofing ceilings, walls and floors, which will give a significant increase of up to 64 dB!

Installation of thin noise insulation is very simple, and not only professionals can handle it, but anyone who has ever held a hammer drill and a screwdriver in their hand.

MaxForte SoundPRO is mounted on the wall using ordinary plastic dowel mushrooms, which can be purchased at any hardware store. It is hung on the wall using the butt-to-butt technology, after which it is covered with a layer of GVL (gypsum fiber sheet). All seams of the sheets must be glued with a special vibroacoustic non-hardening sealant. After the soundproofing is sewn up with a layer of GKL (gypsum plasterboard). The seams of the GVL and GKL sheets should be in a run, that is, they should not match.

Visually about the installation of thin sound insulation MaxForte SoundPRO you can see in the video.

Thin wall soundproofing with panelsSoundGuard EcoSoundIsol

EcoZvukoIzol SoundGuard panels are a unique material for soundproofing walls and ceilings, which allows you to achieve silence in the apartment and not lose usable space.

SoundGuard EcoZvukoIzol panels are made of a durable multi-layer cardboard profile based on the honeycomb principle, which are filled with thermally treated mineral quartz sand. The quartz filler used is very fine, exactly the same as an hourglass. It is this filler that makes it possible to achieve an impressive weight of the panel - more than 18 kg per m2, and according to the laws of sound insulation, the heavier the material, the worse it transmits sound (wool transmits sound very well, but for example, a brick wall or a steel door is much worse). In addition to weight, quartz sand, due to its fine fraction, perfectly dampens and absorbs almost all sound frequencies - from air to shock.

How to mount panelsSoundGuard EcoSoundIsol?

Installation of panels is very simple and almost anyone can handle it. are attached to the wall using SoundGuard DAP acoustic dowels, which are hammered into holes pre-drilled through the panel in the wall. After that, all seams and joints are smeared with sealant and the entire wall is sewn up with drywall.

Mineral noise absorbing material "Shumanet-BM"

This soundproof the material made from basalt fibers is considered to be premium grade mineral sound absorbing board. One side of the mat is laminated with a fiberglass layer, which helps to maintain the integrity of the slab and keep the internal basalt fibers in one position to prevent their small particles from entering the room. This is especially important in cases where the sound-absorbing material will be covered by perforated acoustic panels.

Packing of soundproof boards "Shumanet"

Plates « Shumanet BM" are produced in accordance with the requirements of SNiP 23 — 03-2003 Noise protection. They have the following technical and operational characteristics:

	Indicators
Standard plate size (mm)	1000x500 or 1000x600
Plate thickness (mm)	50
Material density (kg/m³)	45
Number of boards in a package (pcs.)	4
Area of ​​boards in one package (m²)	2.0 or 2.4
Weight of one package (kg)	4.2÷5.5
Packing volume (m³)	0.1 ÷ 0.12
Sound absorption coefficient (average)	0.95
Flammability (GOST 30244-94)	NG (non-flammable)
Water absorption at partial immersion in water for 24 hours, in% of the total volume	Not more than 1÷3%

Acoustic tests to determine the sound absorption coefficient were carried out in the measurement laboratory of the Moscow Research Institute of Building Physics at the Russian Academy of Architecture and Building Sciences.

The basis of "shumanet" are basalt fibers

Having a low degree moisture absorption, this soundproofing material can be used not only in rooms with normal humidity, but also, for example, in the bathroom. In addition, it is great for soundproofing stretch and suspended ceilings, and, of course, walls and multilayer partitions made in the form of a sandwich of drywall, plywood, fiberboard and other sheet materials.

Soundproofing walls using "Shumanet BM"

The installation of the plates of this sound insulator takes place according to the same principle as all types of mineral wool. However, one must take into account the fact that the material will be used primarily as sound absorber, and only then is considered as an additional insulation.

Work is carried out in the following sequence:

• On the prepared one, markings are made to secure the elements of the crate. Since the width of the mats is 500 mm, and they should stand between the bars by surprise, the distance between the guides should be 450 ÷ 480 mm. If mats 600 mm wide are purchased, then, accordingly, the distance between the bars should be 550 ÷ 580 mm.
• Further, the elements of the crate themselves are fixed, but at the same time, in order not to weaken the basic qualities of the soundproofing material, experienced craftsmen advise you to follow a number of simple recommendations:

- For lathing, it is best to use a wooden beam, and not metal profiles, since metal is a good conductor of sound, it can resonate, and wood tends to dampen sound waves.

- In addition, in order not to create bridges for the passage of sound, it is recommended to make spacers between the wall and the lathing bars from a thin soundproof material, for example, felt or strips of basalt wool 8 ÷ 10 mm thick.

- If, nevertheless, a metal profile is chosen for the crate, then it is better to move it away from the wall with a soundproof gasket by 12 ÷ 15 mm.

- In the event that the area soundproof the room is large enough, and it is possible to take out the crate for sound-absorbing material and cladding 100 mm from the wall, then you can use special details - hangers. They are screwed to the wall through wooden spacers, and the bars are already fixed in them.

Another option is the use of special suspensions, which are designed specifically for noise-absorbing structures. Structurally, such a product already has a special damper layer, which effectively dampens vibrations without transferring them to the frame guides.

Special suspension used for soundproofing work

If a guide bars fixed in the above way, then the sound insulator mats are mounted in two layers. The first of them is installed behind the elements of the crate, close to the wall, and the second - between the guides.

Two-layer placement of shumanet panels

• Ultimately, upon completion of the installation of the Shumanet BM panels, the walls should look like this:

Next, over the mats soundproof material is fixed vapor-permeable diffuse membrane. Then they proceed to the installation of drywall or plywood sheets, which, in turn, will become the basis for finishing work. However, it is quite possible to replace this layering by fastening directly to the guide rails of a wooden decorative lining.

Next - the wall is tightened with a diffuse membrane and sewn up with drywall or plywood

It should be noted that all sound and heat insulating materials made in mats or rolls are mounted on walls according to the same principle.

"Teksound" - a new direction in sound insulation technology

Texound is not yet as popular as mineral wool or polystyrene foam, as it is a relatively new sound insulator. The most important advantage of "texound" over others soundproof materials is that it practically does not “steal” the useful area of ​​\u200b\u200bthe room, since it has a small thickness.

The main advantage of "Teksound" is the highest efficiency of sound insulation with a small thickness of the material itself.

This sound insulator is used for all surfaces of the room - it is fixed to the ceiling and walls, and also laid on the floor.

It should be noted that some craftsmen use "texound" in combination with thermal insulation materials, and such a bundle only increases the effectiveness of its use. But, unfortunately, the premises in apartments most often do not have extra space that can be given over to a “powerful” multi-layered sound and heat-insulating structure. In this regard, a material was developed that is able to protect rooms from excessive noise and not reduce the size of the room.

To achieve the desired effect and protect the room from outside sounds, it is necessary to cover all surfaces of the room with soundproofing material, otherwise it will not be possible to achieve the desired result.

Texaund was developed in Spain by specialists from the well-known company TEXSA, and its mass industrial production was also started there. It is in this country that the largest deposit of the mineral aragonite, which is the main raw material, is located.

To be more precise, the base component is calcium carbonate (CaCO³). Aragonite is very rich in this compound. In addition, calcium carbonate is the main constituent of many calcareous rocks, including chalk, marble, and others.

Harmless polymer compositions are used as binding components, and as a result, high-density membranes are obtained, but at the same time very flexible and elastic, with pronounced viscoelastic qualities, which is extremely important for sound insulation of complex building structures.

Sound insulation of rooms with this material is very effective even if canvases with a very small thickness are used. "Teksound"Able to absorb and scatter even sound waves of great intensity, which come not only from the outside, but are also created inside the room, for example, with very loud music.

Texounda canvas covered with a protective film

"Teksound" is produced in canvases (membranes) and goes on sale in rolls packed in polyethylene. It has the following technical and operational characteristics:

Name of material parameters	Indicators
Material density (kg/m³)	1900
Average web weight (kg/m²)	6.9
Area covered by one package (m²)	6.1
Weight of one package (kg)	42
Sound insulation coefficient Rw (average)	28
Flammability (GOST 30244-94)	G2
Elongation at break (%)	300
Manufacturing materials	mineral aragonite, plasticizers, polyolefins, spunbond

In addition, the material has the following advantages:

• "Texound" is resistant to temperature extremes. Its elasticity does not decrease at all even at negative temperatures up to -20 ° C .
• The material has a pronounced flexibility and plasticity, and this "Teksound" is somewhat reminiscent of rubber.

"Texound" with its plasticity resembles dense rubber

• The material is resistant to moisture and will never become a zone of mold or fungus, as it has antiseptic properties.
• The operating time of the “texound” is not limited.
• "Teksound" is perfectly combined with other materials, and can be applied in a complex system.

"Teksound"Subdivided by its thickness, size and shape of release, may have additional layers that improve its characteristics. The main brands are presented in the table:

Installation of "texound"

Almost any base is suitable for mounting this material - concrete, drywall, plastic, wood, metal and others. The main thing is that the surface is well prepared - leveled, cleaned of old coatings, primed and dried.

If there is a qualitatively applied layer of plaster on the wall, then it must be primed, and then installation can be carried out directly on it.

The work can be done in two ways. In the first of them, only soundproofing material is used, and in the second, it is used in combination with a heat insulator.

The first option - without additional insulation

• Glue is applied to the prepared surface. For mounting " texound"A special mounting adhesive is used, which is sold in liquid form, ready for use, in canisters. After lubrication, it is necessary to wait 15÷20 minutes until the glue sets.

• Further, the soundproofing material itself is mounted on the glued wall, which must be measured and cut off in advance, and also pre-lubricated with glue.

Special glue is applied both to the surface of the wall and to the Texounda canvas itself.

• If self-adhesive material is purchased, then installation will be much easier, since it will not be needed for laying, and you will just need to remove the protective film and attach the material to the wall.
• Next, the “texound” sheet must be pressed as tightly as possible to the surface, and then additionally walk over it with a roller. This must be done in order to achieve its best adhesion to the wall surface over the entire area, without leaving air bubbles.

Welding the Texound joints with a gas burner

• Cloths "Teksounda"Be sure to overlap, by about 50 mm. The sheets are glued together hermetically. This process is carried out using "liquid nails" glue or by heating the material with hot air or a gas burner - while adjacent sheets are welded. If at least small gaps are left between the canvases during installation, then the effectiveness of sound insulation will be significantly reduced.

Fully texounded doorway

• If the installation of "Teksound" is carried out on the ceiling, then it is glued in small sheets, since the material is quite heavy, and it will simply be impossible to hold a solid sheet from wall to wall.
• After gluing the canvas, if necessary, it is additionally fixed on the wall with fasteners - “fungi”, the very ones that are most often used for mounting polystyrene foam or mineral wool.

The second option - with the use of thermal insulation

Complex installation is carried out if the wall needs not only soundproof but also insulate. If there is such a task, then the work is carried out as follows:

• On the primed wall along the edges, the crate frame is fixed.

Frame for "Texound" along the perimeter of the wall

• The next step is to immediately glue Texound on the entire wall in one version, and in the other, heat-insulating material is preliminarily laid. However, the first method shows a higher efficiency for sound insulation.
• If thermal insulation is adjacent to the wall, then "texound" is first fixed with "fungi", and then additionally pressed with metal suspension strips.

Fixing the "Texounda" canvases with "fungi" dowels

• To achieve the required place for installing the insulation material, the metal profile of the frame is fixed in suspensions at a distance of 40 ÷ 50 mm from the wall. In this case, it is necessary to set each of the profiles according to the building level, otherwise the frame sheathing will not be even.

Installation of a metal frame on top of the soundproofing sheets

• The next step is the installation of insulation. The most environmentally friendly of suitable insulation materials that can be installed independently is basalt-based mineral wool. If financial facilities, then you can use the above-described "Shumanet BM", which is not only noise absorbing but good thermal insulation material.

• It fits tightly between the racks of the crate and is pressed against the Texound, mounted on the wall.
• Upon completion of the installation of insulation, the wall should look like this:

• It is advisable to tighten the heater vapor permeable diffuse membrane.
• The next step is . In some cases plywood or OSB sheets are used for sheathing.
• The sheets are fastened to the racks of the crate by self-tapping screws, the heads of which are recessed into the sheathing material by 1.5 ÷ 2 mm.

• Then the joints and holes from the caps of the self-tapping screws are sealed with putty.
• Further, the surface is primed and puttied completely, and after that you can decorate the walls with decorative material.

Drywall - the most convenient material for leveling walls

The wall that received soundproofing and insulating protection, it is necessary to prepare for further work - to achieve a flat surface, which will become the basis for finishing materials. As well as - in special publications of our portal.

Existing schemes for mounting "texound"

Masters use various installation schemes for this sound insulator. Depending on the convenience of performing work, the area of ​​\u200b\u200bthe room and the required efficiency of wall insulation from external noise, you can choose any of them. The only drawback of these structures is their thickness, which even in the best case will be at least 50 mm.

First option

This design will have a thickness of 50 mm.

• They begin to mount it with the fact that the prepared metal profiles from the side of their contact with the wall are pasted over with self-adhesive tape "Teksound S BAND 50". This must be done in order to avoid the transmission of sound and vibrations from the wall through the metal frame into the room.
• Further, the frame elements are fixed to the wall with dowels, and heat-insulating, sound-absorbing mats are mounted between them.
• Then, soundproofing material is glued onto the sheets of drywall, on their inner side. In this case, Texound 70 is well suited.
• After that. drywall is fixed on the racks of the frame, and its seams are sealed with putty.

Second option

The thickness of the structure with this option will be 60 mm.

• In this case, a thin heat insulator is first fixed to the wall. You can use foil insulation by setting it with a reflective surface towards the room. The insulation should cover the joints of the wall with the floor and ceiling, that is, go to them by 150 ÷ ​​200 mm.
• On top of it is made installation of a metal frame, which in the same way as in the first version of the design, it is attached to the wall.
• Further, insulation mats are placed in the frame, which are covered with drywall with Texound 70 glued to it.

It should be noted here that the heat-insulating material attached to the wall can be replaced with "Teksound FT 75", which has an additional layer of felt.

Third option

The thickness of the third design option is 70 ÷ 80 mm, as it consists of more layers.

• The first layer to the wall is installed heat-insulating material.
• The second layer is the Texound sound-absorbing membrane.
• A crate is mounted on top of it.
• Then the insulation mats are installed.
• Sandwich panels are fixed to the structure with the last layer, consisting of two sheets of drywall, between which Texound is laid.

When purchasing soundproofing material of this type, it is recommended to provide the consultant of the selling company with the characteristics of the material from which the house is built. The sales assistant will help you make the right choice by determining the thickness and the best form of the Texound release.

Use of foam rubber mats as soundproofing

Acoustic foam can be called the most effective affordable material for soundproofing walls in an apartment. Due to its porous structure, this material perfectly absorbs and scatters sound vibrations.

Acoustic foam rubber is able to neutralize two types of noise - sound and vibration waves, that is, it muffles the sound and scatters low frequencies arising from surface vibrations, for example, knocking or "bass" of music.

The material is quite durable and can be mounted both as an independent soundproofing material and in combination with drywall. Foam mats are available in a wide range of sizes and can be embossed or have a flat surface.

Foam rubber is made by pressing polyurethane foam, after which cutting into standard blocks of 1000 × 2000 mm is carried out. The thickness of the mats varies from 10 to 120 mm. Domestic material is produced in two or three colors, while imported options have a more diverse range of colors, including 10÷12 colors.

Material relief types

Types of relief pattern of acoustic foam can be different. The depth of the relief determines both the total thickness of the material and its noise-absorbing properties.

The main types of reliefs used for the purpose of soundproofing rooms are presented in the tables below:

Material relief height (mm)	25	50	70	100
"Wedge"
	For moderate soundproofing of walls and ceilings.	Effective for absorbing standing sound waves and echoes in medium to small rooms.	For effective soundproofing of rooms of any size.	To absorb low frequencies, it is most often used in large halls.
"Pyramid"
	For moderate wall protection against the penetration of high and medium frequencies.	Standing wave protection in small spaces. In combination with traps for low frequencies, they can completely soundproof the room.	It is used for rooms of any size and is used in conjunction with additional soundproofing elements, such as sound traps.	Same features as wedge material type

There are other, less frequently used acoustic foam elements.

Name of relief type	Characteristics
"Peak"	This relief of mats is less popular and has an unusual pattern. Its lack of demand is explained by lower soundproofing qualities than those of the materials mentioned above.
"Bass Trap"	Waves that have a low frequency are harder to dampen because they are longer. For this, bass traps are installed in each corner of the room, which are designed for rooms of any size.
"Traps of high and medium frequencies"	These elements are installed in large halls. They are designed to capture mid and high frequencies, and create the effect of scattering low frequencies. They are installed in a vertical position, but if the blocks are cut in two and placed at the corners, they will become traps for low frequencies.
"Corner Block"	Corner blocks are made in the form of a triangular beam. They are installed at the corners of the room and at the junctions of two surfaces, and also serve to dissipate low frequencies.
Decorative ceiling tiles	Available with and without embossed pattern. They are designed to change the relief and shape of the ceiling, with the help of which an additional soundproofing effect is achieved.
Insulating wedges	They are used to reduce vibrations from studio equipment and are used as a substrate under it.

Until recently, acoustic foam rubber was rarely used in apartments, since the material tends to accumulate dust. But in recent years, more and more residents of panel houses choose foam rubber to reduce the sound transmission of walls. Due to its high sound-absorbing and scattering qualities, this material is able to make the room almost completely soundproof, provided that it is mounted not only on walls, but also on the surface of the ceiling and floor.

It is very important to note that acoustic foam rubber does not lose its soundproofing qualities at all when it is closed with drywall. The main condition in creating such a design is that the foam mats themselves must be glued directly to the wall base, without any lining.

Soundproofing acoustic foam walls

Installing foam rubber on the walls is not too complicated, so you can easily do it yourself. In this case, it is worth considering the most acceptable method of soundproofing for the conditions of the apartment, but it should be noted right away that the area of ​​​​the room will decrease somewhat.

Installation work is carried out in the following sequence:

• In order for the foam rubber to stick easily, it is best to prime the wall surface and dry it well.
• Next, the mats need to be fixed on the wall. They must fit snugly against its surface, otherwise the sound insulation effect will be partially lost.

• Foam mats can be glued on a wide double-sided mounting tape, liquid nails or heated silicone.
• When all the walls are covered with foam mats, you can proceed to the installation of a frame crate made of metal profiles or wooden beams. Frame guides are fixed at a distance of 50÷60 mm from the wall.
• Racks are mounted in the recesses of the relief pattern directly to the wall. Mounting holes are drilled straight through the foam.
• After fixing the frame of the crate, drywall sheets, plywood, PVC panels or other finishing materials are fixed on the rails. This will in no way reduce the efficiency of the sound absorption of the foam rubber layer, since it will be the first to receive all sound waves coming from outside, absorb them and scatter them.
• In the same way, the foam rubber is mounted on a crate, and then one of the types of suspended ceilings is fixed on it.
• Logs are laid on the floor over acoustic foam rubber, on which a plank or plywood floor is laid. Further, if desired, laminate, linoleum, carpet or other decorative coating can be laid on plywood.

It should be noted that the installation of acoustic mats does not require serious preparatory repair work, and if it is decided to leave the foam panels in the open, then their installation will generally take no more than one day.

Exposed material will require frequent cleaning with a powerful vacuum cleaner to keep a large amount of dust from accumulating inside this porous material. In the event that one of the panels for some reason has moved away from the wall, it can be quickly glued into place without any special preparations.

In addition to the considered soundproof materials, others are also presented in the assortment of building stores. But today, acoustic foam rubber, texound membranes, shumanet plates and similar sound insulators can be called the most effective and safest for installation in an apartment.
