The main function of partitions is to divide the internal space of the house into separate rooms that differ in their purpose: a living room, an office, bedrooms, a library, a kitchen, a bathroom, a toilet, etc. When constructing them, it is necessary to take into account the ability of structures to reduce the intensity of sound waves.
In rooms with a high level of noise, the installation of additional partitions is designed to create a comfortable acoustic environment in the interior by capturing external sounds. Soundproof partition enclosures are designed in such a way that they can:
- to reduce the noise, the source of which is the working equipment;
- absorb extraneous sounds;
- separate noise.
Types of soundproof partitions
The concept of "soundproofing" includes a whole range of measures, the purpose of which is to reduce the noise level in an apartment (house).
The main types of partitions to protect against extraneous sounds are:
Materials required for work
The device of a frame partition with soundproofing qualities is a fairly easy task. With certain knowledge, it is quite possible to cope with it on your own.
For work you need:
- frame materials: aluminum-based profiles or wooden blocks;
- material with soundproofing properties (mineral wool is quite suitable);
- drywall used to hold the insulation inside the frame.
Independent soundproofing device
To obtain a high-quality soundproofing structure, it is necessary to sequentially perform the following steps:
- Mark the exact location of the planned partition. The first step is to mark the position of the details on the floor: profiles, doorway, racks. After that, the indicated dimensions can be transferred to the surface of the ceiling and walls.
- With the help of dowels, guide profiles are attached to the ceiling, floor, walls. The size of the fastening step of the dowels should be approximately 40 cm. A polyurethane tape is glued to the lower part of the surface of the guide profile, after which the racks of the partition frame are installed.
- Pre-prepared drywall sheets are attached to one of the sides. Fastening is carried out in one or two layers using self-tapping screws. Produce cutting of soundproof mats.
- Fragments of mats are suddenly installed into the space of the partition, then the edges of the cut mats, on the one hand, are brought into the inner part of the U-shaped profile, and on the other hand, an elastic stop moment is created.
- Communication elements (wires, sockets, cables) are placed inside the structure, after which drywall sheets are installed on the other side.
- The final stage is the finishing work.
Soundproof materials
In accordance with the function performed, the materials used for soundproofing are divided into sound-reflecting and sound-absorbing.
Solid materials have the ability to reflect sound: brick, concrete, metal sheets, drywall.
Materials that have a cellular, granular or fibrous structure are capable of absorbing sound waves. They are made on the basis of mineral wool or glass wool. Specialized stores sell materials for sound insulation and sound reflection. Today's construction market offers them in the form of rolls and plates. All of them differ in terms of reflection or absorption of sound waves. Many samples may include special components to improve sound insulation properties. You can also purchase mats that have a multilayer structure: in them sheets of foil are located between the layers of mineral wool.
Before buying, you must familiarize yourself with the parameters specified by the manufacturer.
How to calculate the level of sound insulation
The basis of the calculations is the norms of sound insulation of the room. The following formula can be used to determine the level of sound insulation of a partition in the case of a particular material:
IB (sound insulation index) = 32 (logM) + 2 (logD) - 17 dB.
The letter M indicates the surface density of the material from which the wall is made, and the letter D indicates the thickness of the air gap.
There is an easier way: use the calculator programs posted on thematic sites. In this case, the calculations are made automatically and will be more accurate.
Features of soundproofing interior partitions
Drywall constructions
In this case, the main necessary condition for sound insulation is filling the internal space of the partition with a special material. Before starting installation, it is necessary to calculate the number of drywall layers that need to be fixed on each side. With the device of a double layer, a significant improvement in sound-reflecting properties can be achieved. If aluminum-based guides are used, a gasket must be placed between the metal surface and the wall to prevent the transmission of sound vibrations. As fillers for interior partitions, fillers with soundproofing properties are used: mineral wool or glass wool.
Interroom partitions
To increase the soundproofing properties of such partitions, it is necessary to install additional structures. An air chamber should be arranged in the space between the walls and the structure. The gap remaining between the floor and the structure is filled with elastic soundproofing pads.
Sliding partitions
The main task in their isolation is to reduce the gaps between the sections of the structure, the ceiling and the floor to the minimum. For this purpose, a special method of fastening the sections from the top is used. The lower end must be carefully rubbed to the floor without forming a gap. Soundproofing material is placed in the inner part of the partition. As a result of shifting the sections to obtain a single whole, a tight adhesion of the edges of the individual sections to each other should be ensured.
In this instruction, we will describe in detail how to make soundproofing of an interior partition and what materials are needed for this.
When remodeling offices or apartments, homeowners often need reliable soundproofing of interior partitions. In the case of offices, when it is assumed that it is necessary to separate meeting rooms, or offices of departments, managers. In the renovation of apartments, if you need to distinguish between noisy rooms (living room, kitchen) from the bedroom or nursery. Most often today, soundproof partitions are made in two ways:
- install a wall of massive building materials (tongue-and-groove blocks, foam concrete, bricks) and then sheathe it with sound insulation;
- immediately mount the frame structure, sheathed with drywall, filled with mineral fiber boards.
The second method is preferable because it allows you to complete the work faster and at a lower cost.
Choosing the type and characteristics of an interior partition with sound insulation
The ability of building structures made of various materials to withstand noise is determined by the sound insulation index Rw, measured in dB. It shows how much the noise will weaken when passing a particular obstacle. Which interior partitions are better for sound insulation can be determined from the table:
As you can see, the best sound insulation for interior partitions, made of a metal profile frame filled with fibrous mineral slabs and sheathed with drywall. At the same time, Rw of such structures can be increased to 70 dB or more by increasing the thickness of the noise-absorbing layer and using additional high-density materials (membranes, quartz panels) in the skin.
Calculation of the design of a soundproof interior partition
The noise level in the apartment can reach the following values:
- loud conversation - about 60 dB;
- dog barking, human cry - up to 75 dB;
- audio or video equipment turned on at maximum volume - up to 100 dB.
Obviously, interior walls made of bricks, foam concrete or gypsum blocks by themselves cannot serve as a reliable protection against noise. Even if you make them twice as thick as indicated in the table, this will not save the situation, because, according to the law of doubling the mass, the increase in the noise insulation index in this case will be only 6 dB. Thus, if you already have such a partition, then in order to increase its Rw, you will need to install an additional soundproof frame system on it.
The specific parameters of a soundproof partition should be determined based on the level of noise from which it must protect. If it does not exceed 75 dB, then a standard “pie” will suffice, consisting of two layers of plasterboard and 50 mm of mineral wool with a density of 40 kg / m3 between them.
Those who want to ensure maximum protection of the adjacent room from noise should stop at a reinforced structure. As a rule, the layer of mineral filler in them increases by 50 or even 100%. In addition, the cladding on each side can be a sandwich (quartz panel + GKL) or even triplex (GKL + membrane + GKL). With such soundproofing of the partitions in the apartment, you can safely turn on the home theater in the living room at full volume and be sure that the child’s sleep in the next room will not be disturbed.
Installation of soundproof partitions in the apartment
Partition frame installation
The best material for the frame of soundproof partitions is galvanized metal profile. It is not affected by moisture changes, like a wooden beam, and its strength remains stable throughout its entire service life.
The frame is mounted in the following sequence:
Fibrous filling
This stage requires special attention. To achieve maximum sound insulation of the partition, the material must be laid evenly, tightly, without voids, cracks and gaps.
Installation of massive cladding
The noise-absorbing layer is not able to completely dissipate sound waves at a time. To prevent their penetration through the interior soundproof partitions, it is necessary to sheath the structure with massive high-density materials. The task of the cladding is to reflect the remnants of the sound wave back deep into the layer of fibrous filler for its complete absorption.
The following table will help you make a choice, which contains the characteristics of the most commonly used materials.
Installation sequence:
The level of sound insulation of frame partitions directly depends on the quality of the massive cladding. Any crack or loose joint is a sound bridge that significantly reduces the Rw index. As a rule, the material with the maximum density (GVL or sand panel) is mounted as the first layer of massive soundproofing of the partition. The exception is constructions in which a membrane is used to enhance the sound-reflecting properties, located between the sheets of GV and GK.
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 specifically 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 thin soundproofing material MaxForte SoundPRO 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"
Installation of plates of this noise 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 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 compounds 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 high 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:
| Name | Noise isolator release form | Linear parameters of the material, mm |
|---|---|---|
| Texound 35 | rolled | 1220×8000×1.8 |
| Texound 50 | rolled | 1220×8000×1.8 |

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.
Marking and cutting canvases "Teksounda" - 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 hanger 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.
- Thereafter. 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.

| "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 base of the wall, 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.
In addition to significant loads on interfloor floors, laying brick walls is associated with serious time costs and requires professional skills.
If you want to create, then an imitation of a brick niche can be created by finishing a block or frame structure with brick tiles. Corner elements of artificial stone will allow you to achieve a complete illusion of the thickness of brickwork or natural stone.
Concrete
Suitable for construction with a density of 600–800 kg / m³, a thickness of 80–100 mm. A smaller thickness is insufficient in terms of sound insulation and resistance to cantilever loads. However, the walls of foam blocks require plastering. For this reason, it will be difficult to create a small decorative niche, since you will have to saw off blocks to size, plaster surfaces.
Expanded clay concrete partition blocks are moisture resistant and durable, but they do not differ in the stability of geometric dimensions. Such masonry is done only by professionals, and in any case, the surfaces will have to be leveled with rather thick plaster layers.
From tongue-and-groove gypsum boards
Plasterboard tongue-and-groove slabs are larger than foam blocks, but you can create decorative niches with them. Thanks to the tongue-and-groove connection, the structures are stable. They do not require reinforcement, only anchoring to the walls and reinforcing the corners with plaster corners made of galvanized steel. The disadvantage of the material is that it is difficult to saw. Therefore, when sizing, it is necessary to remove the grooves and ridges, and then reinforce the masonry with reinforcing bars or plates. But the walls of foam blocks let steam through, that is, they breathe. Moreover, gypsum contains water and acts as a humidity regulator in rooms with normal humidity.
Tongue-and-groove gypsum boards weigh significantly more than concrete blocks, so they are only suitable for houses whose floors are designed for a distributed load of more than 800 kg / m2.
Another disadvantage is high elasticity. Because of it, a drum effect appears - a relatively low level of sound insulation at frequencies of 100–200 Hz.
Partitions with a pocket for a sliding door, as a rule, are made of drywall. It can be based on a factory case made of profiles of a special section. The design provides the possibility of adjusting the canvas in height.
Porous ceramic
Porous ceramic blocks are 2–2.5 times lighter than bricks and at the same time hold fasteners well. If you use chemical anchors, then even suspended plumbing can be mounted on a 130 mm thick wall.
The large format of the blocks speeds up the laying, the grooves and ridges on the side ends strengthen the partition, and the ribbed surface ensures reliable adhesion to the plaster layer.
The disadvantages of porous blocks include a relatively high water absorption. This problem can be solved with the help of a water-repellent primer and cement plaster.
Plasterboard
Practically does not load the ceiling, does not require laborious work and allows you to lay wires and pipes hidden without problems.
In recent years, instead of the usual fastening with self-tapping screws, a notch is more often used: a hole with bent edges is made with a special tool resembling pliers in two contacting walls of the profiles. Fixing with a cutter speeds up installation, in addition, there are no protruding screw heads on the frame, and the drywall sheet lies perfectly evenly on it. However, when fastening with a cutter, it is more difficult to correct errors, and besides, it is less durable, so it is important to observe the required screw pitch - 250 mm.
Legal notice of redevelopment
with housing authorities. If the design calculation shows an increase in the load on the floor, then it will be difficult to obtain permission, since a technical opinion from the house designer will be required.
- Redevelopment that affects load-bearing walls or unloading non-bearing partitions can only be started after obtaining permission from the housing inspection authorities.
- When redevelopment, it is impossible to increase the load on the floors in excess of the allowable for the project (calculation for bearing capacity, for deformations).
- It is difficult to agree on the replacement of the partition with a heavier one.
- They will not allow redevelopment, in which your bathroom will be above the kitchen or living room of the apartment below. This rule also works for the arrangement of apartments in monolithic new buildings, where new walls of wet zones are erected according to the floor plan.
How to avoid installation errors
A common mistake when arranging interior partitions is their incorrect location. The owner of the apartment may incorrectly estimate the dimensions of the room (for example, a dressing room), the architect may not understand the wishes of the customer, the foreman may read the plan incorrectly, the workers may see the “wrong mark”. The wall has to be dismantled and rebuilt, time wasted and costs increased. Therefore, it is highly desirable for the owner of the apartment, together with the architect (designer), armed with a plan and a tape measure, to come to the site in order to control the laying of the first rows.

Purpose of soundproofing systems
Room dividers without appropriate fillers cannot guarantee noise protection. Housing structures with noise reduction function are designed to:
- Delay loud sounds;
- Reduce vibration from noise;
- Minimize the sound from household appliances.
Soundproofing - a range of measures to reduce the intensity of noise in the premises of an apartment, private household or entertainment venue.
Types of structures that protect against extraneous sounds
Revecon offers a variety of interior systems that can provide excellent protection from neighbors and unwanted vibrations.
Types of partitions for apartments and cottages:
| System types | Specifications |
| Frame soundproof partitions and walls | Structures that reduce the level of noise pressure during the passage of waves through them. The main task of such partitions is to reflect sound, creating an obstacle when vibration does not pass through the system. |
| Noise-absorbing structures | When arranging them, materials are used that absorb sound, reflect the energy of the wave, when it interacts with the interior wall. |
| Soundproof systems | Their goal is to completely exclude the penetration of extraneous noise, not to let it out or into the room. |
When arranging sound-absorbing partitions, Revecon engineers use high-quality sound-absorbing and sound-insulating materials. Only in this way can an adequate level of protection against extraneous vibrations be ensured.
Choice of soundproofing materials
The use of drywall, which has special characteristics, will reduce the level of noise penetrating through interior structures.
What is better for soundproofing an interior partition:
- Membrane - thin sheets supplied in rolls;
- Noise dampening boards.
The base of the membrane is a polymer sheet protected by a layer of felt particles. The thickness of the material is 2.5-12 mm, which allows the use of some types of raw materials in the arrangement of thin structures. The plate acts as a sound barrier, blocking the passage of waves. Felt coating enhances the effectiveness of protection.
As a complement to membranes or as an alternative, Revecon engineers use different materials with a porous structure that provides excellent sound absorption, due to which sound insulation performance is improved.
Using the latest technology
Competition in the market of finishing and building materials forces manufacturers to improve the quality of their goods. To this end, work is carried out in the following areas:
- Arrangement of acoustic GKL;
- The use of special filler with sound-absorbing properties;
- Elastic materials under the frame, reducing sounds from mechanical impact;
- Filling structures and arranging false panels;
- Cellulose fillers inside the system.
Thanks to modern technologies and the use of high-quality materials, Revecon produces partitions of any complexity with varying degrees of noise reduction.
Sound insulation of interior panels: instructions
It is easy to assemble a high-quality partition that provides reliable noise protection with experience and qualifications. This will require wood bars or an aluminum profile, a mineral filler and a material that prevents the penetration of waves through the frame - GKL.
How to soundproof an interior partition:
- Apply the markup of the future structure to the surface of the floor covering, then the ceiling and walls.
- Fix the profiles with dowels (every 40 cm). Cover the guides with polyurethane tape. Install the skeleton racks.
- On the one hand, using self-tapping screws, fix the GCR in one or more layers. Cut sound absorbing mats.
- Install the prepared membranes inside the system by surprise. Bring the edges into the space of the U-shaped aluminum profile on one side, on the other, make an emphasis.
- Place communications inside the partition - wires, sockets, cables. Fix the GKL on the other side.
At the final stage, Revecon engineers perform finishing work, taking into account the characteristics of the interior panel, the characteristics of the room and the wishes of the customer.
Possible mistakes when creating soundproofing
To ensure the proper quality of noise reduction, Revecon masters do not recommend finishing the room exclusively with sound-absorbing boards, placing noisy equipment anywhere in the building, or constructing walls with 3-layer gypsum board with filler.
Sound insulation can only be created using the "mass-elasticity-mass" system, with a minimum thickness of 40-50 mm.
If you need to competently equip the soundproofing of interior partitions, contact Revecon. Masters will take measurements and prepare a design of any complexity, taking into account all your wishes.
