How to make a partition soundproof. Soundproofing device for partitions

Soundproofing room partitions is very important. Sound waves travel through surfaces with different strengths. Extraneous noise makes it difficult to relax or concentrate on important work. Soundproofing partitions help reduce the strength and intensity of sound vibrations: let's look at which ones to install in an apartment and how to properly install such structures.

Sanitary and hygienic requirements require a certain sound insulation index in residential premises. The minimum value for partitions between rooms and between the kitchen and the room is 41–43 dB, and between the bathroom and the rest of the apartment is 47 dB. But not only this index is important. There is such a thing as low-frequency noise. It is created by working electrical appliances. This sound is not loud, but annoying. If we compare a monolithic partition structure and a lightweight partition, then even with equal index values, the first one will reflect low-frequency noise much better.

To achieve maximum protection from extraneous sounds when installing a lightweight structure, you will need to lay a sound-absorbing layer inside it.

It is important to remember that swinging or sliding elements, no matter how tightly they close, worsen sound insulation.

There are also special partition structures that can create the desired level of silence even in the noisiest family. These options include:

Element type	Design characteristics	Result
Frame partitions with a special layer.	They are made of building materials, the outer side of which reflects noise, and the inner layer absorbs it.	Reduce the degree of sound pressure, reduce its intensity to a safe level for nervous system level.
Sound-absorbing structures.	Made from materials that absorb sound wave energy.
Soundproof structures.	They are based on compounds that simultaneously insulate and absorb sound.	They completely remove noise, preventing it from penetrating either inside or outside the room.

Soundproof multilayer partitions performed well.

In them, sound is reflected by a hard plasterboard lining and absorbed by an internal soft layer made of special materials.

The more rigid the outer layer and the softer the inner layer, the quieter it will be behind such a wall.

It is believed that such plasterboard partitions are better than monolithic ones due to savings usable area, ease of installation and budget price.

IN panel houses sometimes load-bearing walls They do not have the best sound insulation, and there is nothing to say about internal ones. For example, monolithic partitions made of tongue-and-groove gypsum slabs perfectly relay sound. In this case, there are two options - replace them with multi-layer gypsum plasterboard structures with a layer of sound insulation or sheathe them with soundproofing boards, and on top - plasterboard sheets. The second option is simpler, but will “steal” precious centimeters of usable space.

You can improve sound insulation without constructing special structures using carpet, draped curtains, upholstered furniture and special acoustic screens. Such screens reduce noise levels, but cannot completely eliminate them.

Required Tools

Soundproofing partitions made of plasterboard are the easiest to construct. But for this you need to stock up not only on materials, but also on tools.

The minimum required for a beginning builder includes:

• spirit level, laser level or an ordinary construction device;
• screwdriver;
• plumb line;
• roulette;
• screwdriver set;
• metal scissors;
• drywall cutter;
• ruler and pencil.

Without this minimum, work cannot begin. But if there is additional tools, installation will be faster and easier. For example, you can trim drywall sections with a special plane, and use a grinder to cut metal profiles.

Soundproofing materials for partitions

Hard soundproofing material (concrete, metal, brick, plasterboard) in partitions will reflect sound, while soft, fibrous and porous material will absorb sound. But the last group, in turn, is divided into three subgroups with different qualitative characteristics:

Rigidity	Absorption coefficient	Base type	Qualities
The hardest of the soft	0,5	Suspended or granulated mineral wool, perlite, pumice, vermiculite, fireclay.	Resistant to fire and chemicals, low thermal conductivity, frost resistance.
Medium hardness	0,5 – 0,75	Mineral wool, polyurethane foam, fiberglass.	Light weight, high thermal insulation, wear resistance and adhesive strength, environmental friendliness.
The softest	0,7 – 0,95	Mineral wool, felt, fiberglass.	Fire resistance, elasticity, lightness, non-hygroscopicity, increased steam conductivity.

All these options relate to inorganic insulators. In interior decoration materials are used that have a noise absorption coefficient of at least 0.4. It must be indicated on the label or in accompanying documents.

Sometimes an organic type is used - fibreboards. They are used in the construction of temporary and technical structures. For residential construction Fibreboard cannot be used due to low fire resistance.

Made from really hard materials, volumetric partitions made of porous building materials reflect and dampen sound well: aerated concrete, ceramic blocks.

For ideal silence when laying, leave an air gap or cover such walls with plasterboard.

Sound insulation of frame plasterboard partitions cannot be done without special self-adhesive tape. It is applied to the metal profile, after which installation is carried out. And cracks and seams must be sealed with putty. Connoisseurs of strict silence will prefer soundproofing sealant.

Which soundproofing material to choose

Fillers for noise absorption differ not only in their soundproofing coefficient, which is important for soundproof partitions, but also in other qualities. They must be taken into account when choosing an insulator for residential premises. What are the main features of the most popular fillers:

In addition to internal filling, there are also external noise absorbers. These include spraying cellulose fibers.

Such a surface can be painted in any color; the base will not lose its valuable qualities.

The coating is capable of correcting acoustics, and looks like “fur coat” plaster. Most often used indoors for entertainment and commercial purposes - clubs, restaurants, banks. If a different decor is intended, foamed cellulose is applied to the plasterboard panels so that the layer is inside the structure.

Rolled or sheet cork is a good soundproofing option with the best environmental properties. It is also used for surface decoration of walls. Almost no dust settles on the cork and it looks decorative. The coating will fit perfectly into the interior of an apartment in a minimalist or eco-style.

This unusual building material from the famous brands Knauf and Aku-Line reduces the penetration of sound waves.

In this case, the plasterboard partition has maximum sound insulation.

Load-bearing walls can also be upholstered with acoustic material, because in many houses you can learn everything about the lives of your neighbors through them.

Noise insulation is achieved due to a large number of holes that reflect sound waves directed at the surface of the partition. And on the inside there is a sound-absorbing non-woven fabric.

Almost complete absence of noise in a room can be achieved by creating frame structure from acoustic plasterboard and fill the internal cavity with mineral or ecowool.

Soundproofing of interior partitions

Partitions between rooms are not load-bearing, so they are often made from plasterboard. This material is inexpensive, easy to process, its smooth surface gives room for imagination in decorative finishing. Soundproofing of plasterboard partitions is done during their installation and also does not involve any particular difficulty.

What you need to know for successful soundproofing of your home

The sound insulation of multilayer frame partitions depends on the rigidity and thickness of the frame cladding material, the distance between the cladding sheets, and the sound absorption coefficient of the insulation layer inside. Compared to thick monolithic ones, narrow structures made of several layers protect better from extraneous sounds and save useful space.

But before choosing a design solution for the partition and building materials, you should find out what kind of noise you need to escape from:

• from air - sounds propagated through the air (music, human speech);
• from shock - noise of working household appliances, the trampling of neighbors' feet;
• from structural - vibrating noise from construction tools, transmitted across all partitions of the building.

If you choose sound insulation carefully, you can protect yourself from fans of rock music behind the wall (more than 70 dB) and even from fans of working with a hammer drill (about 110 dB). Insulation materials there are many, and regarding their characteristics of each variety it is worth seeking advice from professionals.

But there are points that do not depend on the qualities of the partition material itself. Thus, when attaching the frame to the walls, ceiling and floor, the interface areas must be insulated with elastic gaskets. They will maintain the durability of the structure and reduce vibration.

If electrical communications are planned inside the partition, all wires must be hidden in corrugated pipes for fire safety purposes.

How is soundproofing plasterboard walls created?

Such structures are usually a kind of “sandwich” of plasterboard with insulating material inside.

The sound insulation of the partition will be better if you make several plasterboard and internal layers.

Fibrous materials in the form of slabs or rolls are most often used as insulating filler. Each type requires its own approach to installation:

If it is intended to enhance sound insulation due to a layer of air, it is necessary to use limiters. Additional internal frame strips will prevent the filler from falling out and skewing.

In structures where there are several insulating layers of different composition inside, the following installation rules must be observed:

1. A thermal insulation layer is placed closer to the potential noise source.
2. A protective plastic film is placed on it.
3. The next layer is soundproofing.

It is usually located on the other side of the frame, but it can also be installed between heat shields. In this case, additional fasteners will be required to hold the sound insulator.

Soundproofing of gypsum plasterboard partitions

Many people are interested in the question: in order to achieve ideal sound insulation, what should be the thickness of plasterboard partitions? It is impossible to give a single answer to it. The conditions in each living space are different; the specifics of the material and the level of potential sound “threat” must also be taken into account.

Type of plasterboard partition	Without separating layer	With one separating layer inside	With two separating layers	With additional insulation
Layer thickness	Two layers of plasterboard - 25 mm, single frame - 50 mm (double - 80 mm), insulator - 25 mm.	Two layers of plasterboard - 25 mm, double frame - 80 mm, insulator (two layers) - 50–100 mm, OSB separating board - 15 mm.	Two layers of plasterboard - 25 mm, double frame - 80 mm, insulator (three layers) - 75–150 mm, two OSB separating boards - 30 mm.	Two layers of plasterboard - 25 mm, double frame - 80 mm, insulator, sheet insulation and air gap (depending on the number of layers) - 140–190 mm.
Final width of the structure	100–180 mm	170–220 mm	210–285 mm	245–295 mm

The thickness of the soundproofing false wall is adjusted depending on the architectural and design features of the room and the selected material. For example, it is planned to install two layers of Knauf sheet (gypsum plasterboard for partitions) with a layer of sound insulation in a room in a brick house.

Thick load-bearing walls will smooth out the noise flow from the outside, so the sound insulation layer will depend specifically on internal sounds. If you decide to partition a room to separate the bedroom and living room, an insulator with a thickness of 25 to 50 mm is sufficient. The final wall width is 10–12.5 cm.

The higher the noise level, the stronger the sound insulation of plasterboard partitions should be, and the thicker the false wall itself will be.

When calculating the width of the wall, decorative finishing is also taken into account: how thick a layer of putty or plaster will be applied, whether it will be covered with plastic panels or other finishing materials.

Making a soundproof partition with your own hands

It is not difficult to arrange noise insulation of interior gypsum plasterboard partitions with your own hands. First of all, it is necessary to secure the partition frame. Its production is not much different from creating a simple partition element without insulation, but there are certain nuances. The difference is that soundproofing material is required between the supporting structures.

How to do this job correctly:

It is important that there are no voids left between the slabs or strips of insulator. In this case, communication connections (wires, pipes) must be laid inside the structure. Electrical wiring must be placed in special plastic casings or corrugated tubes.

To improve the soundproofing qualities of the partition element, you can cover it with sheets of plasterboard in two layers on each side.

It is not difficult to mount such a structure: another sheet is fixed on top of the sheet fixed to the frame. In this case, it is necessary to mix the seams so that the joints of the bottom layer in relation to the top ones are at a distance of at least 20 cm. Top layer They are also treated with sealant, and the seams are covered with fiberglass tape. The partition will reflect sound better, but its width will increase by 2.5 cm.

The finished wall needs to be puttied, and then proceed to decorative processing. This could be painting, wallpapering, covering decorative plaster. The walls in the bathroom can be covered with plastic panels or covered with ceramic tiles.

Covering with cork panels will give the room an interesting design and improve the soundproofing qualities of the structure.

Soundproofing interior partitions requires responsibility, care, and accuracy. It is necessary to strictly adhere to the technology installation work and choose quality materials. If everything is done correctly, the reward will be perfect silence and independence from noisy neighbors.

It is very important to properly soundproof partitions, because they are much thinner than load-bearing walls, and how people in the room will feel depends on them.

The partition performs the function of dividing space into different parts. The use of this design may be needed in premises of any type, both in residential buildings and in offices, country houses, etc.

Sound insulation consists of such components as: sound reflection, sound absorption, acoustic comfort. Each of them is important in its own way, and in the absence of at least one, it makes no sense to talk about complete and comfortable sound insulation.

Useful information:

Types of partitions

The partitions themselves can be multi-layered or single-layered.

Single-layer partitions created from self-supporting material. This material is very dense and contains a rigid binder. For example, plaster, brick, reinforced concrete. In these structures, sound insulation is achieved through thickness and mass. The main disadvantage of such partitions is their large thickness, which will “eat up” the room.

Multilayer or frame partitions is a system of several layers of different materials. It is important that the materials must have different densities, including both rigid and soft materials. In this design, hard layers are often used - gypsum or brick as a base, and soft layers (MDF) as sound absorbers. Due to the specific structure of lightweight materials, sound vibrations that pass through it become weaker due to air friction in the pores.

It is important to note that layers such as cork, polystyrene foam and polyurethane foam are not suitable for soundproofing structures. It's all about insufficient density and lack of ability to pass air through itself.

Soundproofing various types septations occur in different ways. So, in a single-layer wall, due to the initially thick wall, the thinness and efficiency of the materials is important, and in a multi-layer wall, the correct “pie” and the ratio of densities and mass are important.

A quick option is a method that was very popular in the past - hanging a rug on the wall. The soft layer and thick dense pile perfectly muffled sounds from neighboring rooms.

Soundproofing materials

The article discusses soundproofing structures made of the following materials:

Gyprock

Or, more correctly, plasterboard - gypsum sheet covered with construction cardboard. There are different types gypsum board; standard, reinforced and special flexible sheets are most suitable for partitions.

Isoplat

Soft fiberboard made from compressed shavings of coniferous trees. The line includes heat and sound insulating boards (especially for interior work), windproof and universal (have a tongue-and-groove fastening, suitable for both indoor and outdoor use).

Cotton insulation

Mineral wool, linen insulation. Such materials, in addition to their main function, have excellent sound absorption properties. They have in their structure many intertwined fibers through which air can pass. Another advantage is the sufficient thickness.

Isotex

Decorative finishing for walls and ceilings based on heat and sound insulating boards Izoplat. Essentially it is the stove itself, covered with washable wallpaper or fabric. Has a tongue-and-groove connection for easy installation, has excellent acoustic properties.

Soundproofing of a single-layer partition

Basically, the soundproofing capabilities of such walls directly depend on how much room you are willing to sacrifice. Taking into account the fact that such structures already have a large mass and thickness, it is recommended to use thin soundproofing boards to save space. Let's think about the carpet on the wall. Of course, now no one will use this method, but there is no need for this. The Isotex and Isoplat product lines have exactly the same property.

Option 1 - Isotex

This is the easiest way to soundproof. The partition is lined with decorative Isotex panels on both sides. The panels are only 12 mm thick, with an airborne noise insulation coefficient of 23 dB. You simply cannot find finer sound insulation with finishing. Isotex allows most of the acoustic energy to be converted into heat and the rest to be reflected. Using such panels you can also adjust the acoustics in the room.

Option 2 - Izoplat and Isotex

This method includes the installation of heat and sound insulating boards, and decorative finishing panels on top of them. In this case, the thickness of the soundproofing layer can be adjusted. Izoplat slabs are produced in thicknesses of 10 mm, 12 mm and 25 mm. This way you can easily select the required thickness. Isotex panels are easily attached to heat and sound insulation boards; installation of all materials can be easily done independently.

Sound insulation of multilayer partition

A soundproofing “pie” can be constructed in several ways, using a frame or, for example, a tongue-and-groove slab (from 80 mm) as a basis. In any case, the efficiency will also depend on the thickness of the materials, their mass and filling.

Option 1 - Adjacency

When using a tongue-and-groove slab, an elastic connection is installed between the partition and the load-bearing wall - a heat and sound insulating board Izoplat. This method will increase the sound insulation coefficient Rw of the entire structure to 41 dB.

Option 2 - Plate, Isoplat and gypsum board

The basis in this design is again a tongue-and-groove slab. First, Izoplat mdf is installed on both sides of it, and gypsum board is installed on top of it. In this case, gypsum board performs the function of sound reflection, and Izoplat - sound absorption. For the best effect, install several Isoplat slabs in front of the gypsum board.

Option 3 - Giprok, Isoplat and insulation

To use this option, you will need to install a frame, inside of which insulation (linen or mineral wool) is placed. In this case, the insulation should be as natural and “breathable” as possible, since others simply will not allow air to pass through and, therefore, absorb sound waves efficiently. Next, the insulation is covered with Isoplat plate, and then with gypsum board. Despite the fact that this design has a small total weight, thick, high-quality insulation has good sound insulation properties and will prevent noise from spreading into the adjacent room.

On any of the above soundproofing schemes of a multilayer structure, you can also install decorative panels Isotex. They will not be superfluous, because the gypsum board will have to be decorated in any case, and the panels will provide acoustic comfort. As a result, you will get a warm partition that will protect you from outside sounds.

Proper soundproofing of walls is the key to a comfortable pastime.

The partition is used to divide space into zones in private buildings, offices or public spaces. Soundproofing of interior partitions is important factor. Sound waves can travel through surfaces. To stop them, you need to reduce the sound pressure. For this purpose, various soundproofing materials are used. This article will look at how soundproofing of partitions is carried out and what is needed for this.

Sound propagation and absorption

Sound is the name given to mechanical vibrations propagated by a source in an elastic medium. By creating vibrations, the source generates pressure that spreads in different directions. The sound wave generated as a result of such processes penetrates the human hearing organs and transmits vibrations to the eardrum, which, when vibrating, is perceived by the brain as sound.

The characteristics of sound propagation directly depend on the density of the medium and can vary greatly. For example, if sound encounters any obstacle along its path, its waves are reflected or refracted.

If a porous material is placed in its path, it absorbs the wave by internal scattering. This characteristic of products is often used in construction for or other surfaces. The materials themselves, produced taking into account such features, are called sound-absorbing or sound-proofing. In the following table you can see a comparison of such materials.

Sound insulation of plasterboard structures

Products made from plasterboard sheets are becoming increasingly popular. When deciding to divide the space of a room into zones, sound insulation must be provided without fail. With proper planning, the costs will be small. The following video will help you become more familiar with this procedure.

She herself has high level soundproofing, but it can be increased by the following actions:

• use of soundproofing materials;
• sound insulation of walls using special technology;
• use of soundproofing fasteners when installing the frame;
• use of special profiles;
• increasing the interval between partitions;
• use of thick frames;
• increasing the thickness of the finish;
• the use of various fillers for the frame.

A plasterboard partition is constructed in two layers: the outer one is a shell made of a sheet of material, and the inner one involves the installation of a special filler.

Its cost is quite high, so fillers can be used. Porous slabs in soundproofing partitions are the main component providing sound insulation.

Soundproofing a partition is impossible without taking into account the metal frame, which is a good conductor for sound.

You will need to lay a sealing tape under the initial horizontal profiles, and metal fastenings mounted with polymer gaskets.

Soundproofing of frame partitions is carried out as follows:

• One side of the frame is covered with a sheet of plasterboard.
• Communications are laid, sockets and switches are installed and connected.
• In inner part The partitions are filled with sound-absorbing material. There should be no empty areas between the sheets.
• The layer is covered with a membrane or porous tape.
• On the other side, a plasterboard sheet is mounted.
• Cracks and empty spaces are filled with sealant.

A comparison of various soundproofing partitions can be seen in the following table.

Use of new developments

Great competition in the building materials market forces manufacturers to invent new soundproof materials. Work is being carried out in the following areas:

• production of acoustic plasterboard;
• use of special fillers with noise absorption function for partitions;
• plastic gaskets that are mounted under the frame and have the function of reducing the sound of an impact;
• filling partitions and installing false walls;
• spraying fibers inside structures.

Acoustic drywall

Various brands have begun producing similar drywall, which significantly reduces the noise level when finishing interior partitions or processing other surfaces. Good sound absorption is ensured by a large number of holes that reflect sound waves directed at the coating. In addition, a non-woven fabric with a sound absorption function is glued to the back side of the material.

Sound-absorbing filler

Soundproofing of partitions is possible by laying sound-absorbing filler inside. For such purposes, polystyrene foam is often used. In addition to sound insulation, the finishing can provide a good level of thermal insulation. By adding a fire retardant, the fire resistance of the filler significantly increases.

Mineral wool slabs also have good sound absorption properties. For sound insulation, acoustic slabs with a thickness of no more than 4 cm are usually used. Good sound insulation can only provide homogeneous slabs.

Fillers for partitions with improved sound insulation parameters are more expensive, but allow you to achieve complete sound insulation in your home. In addition, thinner filler can be used, which reduces the cost of work and loss of room space.

Membranes made of thin fabric coated with pile can provide high quality sound absorption. Their thickness can vary from 2.5 to 12 mm.

Panels made of polyester and polyurethane foam are used as internal fillers and when installing false walls. Some varieties may be a fire hazard because they contain flammable materials.

An inexpensive filler is. It reduces the noise level slightly, but has extremely low efficiency.

Spraying coatings

Spraying of products is often used due to the low cost and simplicity of the procedures. This method allows you to regulate acoustic parameters inside entertainment and public buildings. To implement it you will need the help of specialists.

Possibility of spraying foamed cellulose composition onto various surfaces allows you to avoid installing a frame, which is used to hold plasterboard partitions. The method is inexpensive and not highly labor intensive.

When using special tools, the sound insulation of partitions can be increased by applying cellulose from the inside.

Mistakes when creating sound insulation

Novice builders often make mistakes when trying to soundproof interior designs. The most common mistakes are:

• Cladding houses only with sound-absorbing components. In order to increase sound insulation, the material must be used together with special panels, and large fences with acoustic decoupling must be used in the junction areas.
• Placing noisy equipment in rooms with partitions. The effectiveness of noise reduction materials has limits. It is not always possible to create high-quality sound protection. Equipment that produces a large number of sounds is best located away from partitions.
• Soundproof the partition using three layers of plasterboard with filler. For high efficiency, you need to use special components and install gaskets between the frame and the partition, as well as fill the joints with special sealants.
• Soundproofing buildings with thin soundproofing screens. A soundproof partition can only be created using structures with a minimum thickness of 40 mm.

Soundproofing screens can be seen in the next photo.

As can be seen from the article, soundproofing partitions is possible in different ways. You just need to carefully select the material, since the level of sound protection will depend on it. The work is not too complicated, so even a beginner in the construction craft can handle it. Thanks to the photos and videos used in the article, it will be possible to see in practice how such a procedure is performed.

An important stage in arranging a quiet, full-fledged room is soundproofing interior partitions. If you have kids at home and you want to create a cozy corner for them, protected from loud sounds and neighbors, you must install a noise-absorbing structure.

Purpose of soundproofing systems

Interior partitions without appropriate fillers cannot guarantee noise protection. Housing structures with a noise-absorbing function are designed to:

• Stop loud sounds;
• Reduce vibration from noise;
• Minimize sound from household appliances.

Sound insulation is a range of measures to reduce the intensity of noise in an apartment, private household or entertainment venue.

Types of structures that protect against extraneous sounds

Revecon offers various interior systems, capable of providing excellent protection from neighbors and unwanted vibrations.

Types of partitions for apartments and cottages:

Types of systems	Characteristics
Frame soundproofing partitions and walls	Designs that reduce the level of noise pressure as waves pass 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 and reflect the energy of the wave when it interacts with the interior wall.
Soundproof systems	Their goal is to completely eliminate the penetration of extraneous noise and not let it pass outside or inside the room.

When installing sound-absorbing partitions, Revecon engineers use high-quality sound-absorbing and sound-insulating materials. This is the only way to ensure the appropriate level of protection from extraneous vibrations.

Selection of soundproofing materials

The use of plasterboard, which has special characteristics, will reduce the level of noise penetrating through interior structures.

What is better for soundproofing an interior partition:

• Membranes are thin sheets supplied in rolls;
• Sound-absorbing slabs.

The basis of the membrane is a polymer fabric protected by a layer of felt particles. The thickness of the material is 2.5-12 mm, which allows the use of certain types of raw materials when arranging thin structures. The plate acts as a sound barrier, blocking the passage of waves. Felt spraying enhances the effectiveness of protection.

As a complement or alternative to membranes, Revecon engineers use different materials with a porous structure that provides excellent sound absorption, thereby improving sound insulation performance.

Using the latest technology

Competition in the finishing and building materials market forces manufacturers to improve the quality of their products. For these purposes, work is carried out in the following directions:

• Installation of acoustic gypsum board;
• 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, use quality materials Revecon company produces partitions of any complexity with varying degrees of noise absorption.

Soundproofing interior panels: instructions

Assemble a high-quality partition that provides reliable protection from noise, having experience, qualification can be done without difficulty. To do this, you will need wooden blocks or an aluminum profile, mineral filler and a material that prevents the penetration of waves through the frame - gypsum plasterboard.

How to soundproof an interior partition:

• Apply markings of the future structure to the surface flooring, then the ceiling and walls.
• Fix the profiles with dowels (every 40 cm). Cover the guides with polyurethane tape. Install the skeleton stands.
• On the one hand, using self-tapping screws, fix the gypsum board in one or several layers. Cut noise-absorbing mats.
• Install the prepared membranes inside the system by surprise. Bring the edges into the U-shaped space aluminum profile on the one hand, on the other, focus.
• Place communications inside the partition - wires, sockets, cables. Fix the gypsum board on the other side.

At the final stage, Revecon engineers carry out 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 sound insulation

To ensure proper quality of sound absorption, Revecon experts do not recommend finishing the room exclusively with sound-absorbing boards, placing noisy equipment anywhere in the building, or constructing walls with 3-layer plasterboard 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 properly arrange soundproofing of interior partitions, contact Revecon. Our craftsmen will take measurements and prepare a design of any complexity, taking into account all your wishes.

Soundproofing walls in an apartment, modern materials for which can be found in hardware stores today, is becoming more and more relevant. This can be explained simply - fences in multi-storey buildings standard houses are not able to completely 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, preventing him from getting 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 soundproofing 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 improvements thanks to recent production technologies.

Today a very large number of new soundproofing materials, and it is simply impossible to cover the characteristics of everyone in one article. Therefore, attention will be focused on the most effective ones, which are used specifically in apartment conditions.

Thin sound insulation MaxForteSoundPRO

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 waste precious centimeters of living space?

In this case, innovative thin material for sound insulation MaxForte SoundPRO. It has a thickness of only 12 mm, while its characteristics can compete with sound insulation with a thickness of 5 and even 10 cm! MaxForte SoundPRO is the latest material created 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. During the production of MaxForte SoundPRO, all important points for the effective operation of the material were taken into account: it was selected optimal density(if the density is low, the sound will pass through, if the density 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 or any adhesives. Therefore, in addition to excellent noise insulation properties, MaxForte SoundPRO is safe for health.

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

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

MaxForte SoundPRO is mounted on the wall using ordinary plastic mushroom dowels, which can be purchased at any hardware store. It is hung on the wall using the “joint-to-joint” technology, after which it is covered with a layer of gypsum fiber board (gypsum fiber sheet). All sheet seams must be sealed with a special vibroacoustic non-hardening sealant. Afterwards, the sound insulation is sewn up with a layer of gypsum plasterboard (plasterboard sheet). The seams of the gypsum fiber board and gypsum board sheets should be staggered, that is, not coincide.

You can see the installation of thin sound insulation MaxForte SoundPRO in the video.

Thin wall soundproofing panelsSoundGuard EcoZvukoIzol

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

SoundGuard EcoZvukoIzol panels are made of durable multi-layer cardboard profiles 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 (cotton wool transmits sound very well, and for example brick wall or steel door much worse). In addition to its weight, quartz sand, due to its fine fraction, perfectly dampens and absorbs almost all frequencies of sound - from airborne to shock.

How to install panelsSoundGuard EcoZvukoIzol?

Installation of the panels is very simple and almost anyone can handle it. are attached to the wall using SoundGuard DAP acoustic anchors, which are driven into pre-drilled holes through the panel in the wall. After this, all seams and joints are coated with sealant and the entire wall is covered with plasterboard.

Mineral sound-absorbing material "Shumanet-BM"

This soundproofing The material, made from basalt fibers, is considered a premium mineral sound-absorbing board. One side of the mat is laminated with a layer of fiberglass, which helps maintain the integrity of the slab and hold 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 with perforated acoustic panels.

Packaging of soundproofing boards "Shumanet"

Plates " Schumanet BM" are manufactured in accordance with the requirements of SNiP 23 — 03-2003 “Noise protection”. They have the following technical and operational characteristics:

	Indicators
Standard slab size (mm)	1000×500 or 1000×600
Slab thickness (mm)	50
Material density (kg/m³)	45
Number of slabs per package (pcs.)	4
Area of ​​slabs in one package (m²)	2.0 or 2.4
Weight of one package (kg)	4.2÷5.5
Packaging volume (m³)	0.1 ÷ 0.12
Sound absorption coefficient (average)	0.95
Flammability (GOST 30244-94)	NG (non-flammable)
Water absorption when partially immersed in water for 24 hours, % of total volume	No 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 Russian Academy architecture and building sciences.

The basis of “Shumanet” is 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 excellent for soundproofing suspended and suspended ceilings, and, of course, walls and multilayer partitions made in the form of a sandwich of plasterboard, plywood, fiberboard and other sheet materials.

Soundproofing walls using Schumanet BM

Installation of the slabs of this sound insulator follows 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 additional insulation.

The work is carried out in the following sequence:

• On the prepared surface, markings are made to secure the sheathing elements. Since the width of the mats is 500 mm, and they must stand apart between the bars, 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.
• Next, the sheathing elements themselves are fixed, but at the same time, in order not to weaken the basic qualities of the soundproofing material, experienced craftsmen advise performing a series of simple recommendations:

— For lathing, it is best to use wooden beams rather than metal profiles, since metal is a good conductor of sound and can resonate, and wood tends to dampen sound waves.

— Additionally, in order not to create bridges for the passage of sound, it is recommended to make gaskets made of thin sound-proofing material, for example, felt or strips of basalt wool 8 ÷ 10 mm thick, between the wall and the sheathing bars.

— If, after all, a metal profile is chosen for the sheathing, then it is better to move it away from the wall with a soundproofing pad by 12 ÷ 15 mm.

- In the case that the area soundproof the room is large enough, and it is possible to move the sheathing for sound-absorbing material and cladding 100 mm from the wall, then special ones can be used to attach the bars 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 that effectively dampens vibrations without transferring them to the frame guides.

Special suspension used for soundproofing work

If guide bars secured in the manner indicated above, then the soundproofing mats are mounted in two layers. The first of them is installed behind the sheathing elements, close to the wall, and the second is installed between the guides.

Double-layer placement of “Shumanet” panels

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

Next, on top of the mats soundproofing material is fixed vapor permeable diffuse membrane. Then they proceed to the installation of plasterboard or plywood sheets, which, in turn, will become the basis for the execution finishing works. However, it is quite possible to replace this multi-layering by fastening directly onto the guide lathing of wooden decorative lining.

Next, the wall is covered with a diffuse membrane and covered with plasterboard 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.

"Texound" - a new direction in sound insulation technology

"Texound" is not yet as popular as mineral wool or expanded polystyrene, since it is a relatively new sound insulator. The most important advantage of Texound over others soundproofing materials is that it practically does not “steal” the usable area of ​​the room, since it is small in thickness.

The main advantage of Texound 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 combination only increases the effectiveness of its use. But, unfortunately, the rooms in apartments most often do not have extra space that can be given over to a “powerful” multi-layer sound and heat insulating structure. In this regard, a material was developed that is able to protect rooms from excess noise without reducing the room in size.

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 be impossible to achieve the desired result.

Texaund was developed in Spain by specialists from the well-known company TEXSA, and its mass industrial production began 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 basic component is calcium carbonate (CaCO³). Aragonite is very rich in this compound. In addition, calcium carbonate is the main component of many calcareous rocks, including chalk, marble and others.

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

Soundproofing rooms with this material is very effective even if canvases of very small thickness are used. “Texound” is capable of absorbing and scattering even high-intensity sound waves that come not only from the outside, but are also created indoors, for example, during very loud music.

Texaunda canvas covered with protective film

“Texound” is produced in sheets (membranes) and goes on sale in rolls packaged in polyethylene. It has the following technical and operational characteristics:

Name of material parameters	Indicators
Material density (kg/m³)	1900
Average specific gravity canvas (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:

• "Texaund" is resistant to temperature changes. Its elasticity does not decrease at all even with negative temperatures up to - 20 °C .
• The material has pronounced flexibility and ductility, and in this way “Texound” is somewhat reminiscent of rubber.

"Texound" with its plasticity resembles dense rubber

• The material is resistant to moisture and will never become an area for mold or mildew to spread, as it has antiseptic properties.
• The operating time of the Texound is not limited.
• Texound combines well with other materials and can be used in a complex system.

“Texound” is divided according to its thickness, size and release form, and may have additional layers that improve its characteristics. The main brands are presented in the table:

Name	Sound insulator release form	Linear parameters of the material, mm

Installation of "texound"

Almost any base is suitable for installation of this material - concrete, plasterboard, 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 high-quality 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 carried out 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. To install the Texaund, a special mounting adhesive is used, which is sold in ready-to-use liquid form in canisters. After coating, you must wait 15-20 minutes until the glue sets.

Marking and cutting of Texound canvases

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

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

• If you purchase self-adhesive material, then installation will be much easier, since adhesive will not be needed, and you will just need to remove protective film and attach the material to the wall.
• Next, the texaund sheet needs to be pressed as tightly as possible to the surface, and then additionally walked over it with a roller. This must be done to achieve better adhesion to the wall surface over the entire area, without leaving air bubbles.

Welding Texound joints using a gas torch

• Texound canvases must be overlapped by approximately 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 - adjacent sheets are welded. If even small gaps are left between the panels during installation, the effectiveness of sound insulation will be significantly reduced.

Doorway completely finished with Texound

• If Texound is installed 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 single sheet from wall to wall.
• After gluing the canvas, if necessary, it is additionally fixed to the wall with fastenings - “fungi”, the same ones that are most often used for installing polystyrene foam or mineral wool.

The second option is using 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:

• The sheathing frame is attached to the primed wall along the edges.

Texound frame around the perimeter of the wall

• The next step is to immediately glue Texound onto the entire wall in one version, and in the other, heat-insulating material is pre-laid. However, the first method shows more high efficiency specifically for sound insulation.
• If thermal insulation is adjacent to the wall, the “texaund” is first secured with “fungi”, and then additionally pressed with strips of metal hangers.

Fixing Texound panels with mushroom dowels

• To achieve the required space for installing the insulating material, the metal profile of the frame is fixed into hangers at a distance of 40÷50 mm from the wall. In this case, it is necessary to set each of the profiles according to construction level, otherwise the frame skin will not be smooth.

Installation of a metal frame on top of soundproofing panels

• The next stage is the installation of insulation. The most environmentally safe of suitable insulation materials that can be installed independently is considered to be basalt-based mineral wool. If financial allow funds, then you can use the above-described “Shumanet BM”, which is not only sound-absorbing, but a good thermal insulation material.

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

• It is advisable to tighten the insulation vapor permeable diffuse membrane.
• The next stage is . In some cases Plywood or OSB sheets are used for cladding.
• The sheets are fastened to the sheathing posts using 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 screw heads are sealed with putty.
• Next, the surface is primed and puttied completely, and after that you can decorate the walls with decorative material.

Drywall is the most convenient material for leveling walls

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

Existing texound installation schemes

Masters apply various schemes installation of this sound insulator. Depending on the ease of performing the work, the area of ​​the room and the required efficiency of insulating the walls from external noise, you can choose any of them. The only disadvantage 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 install it by covering the prepared metal profiles on the side of their contact with the wall with self-adhesive tape “Texound 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.
• Next, 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 to the plasterboard sheets on the inside. In this case, Texound 70 is suitable.
• After that. drywall is fixed to the frame posts, and its seams are sealed with putty.

Second option

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

• In this case, first a thin heat insulator is attached to the wall. You can use foil insulation, installing it with the reflective surface towards the room. The insulation should cover the joints of the wall with the floor and ceiling, that is, extend to them by 150÷200 mm.
• On top of it is produced installation of a metal frame, which just like in the first design option, it is attached to the wall.
• Next, insulation mats are laid into the frame, which are covered with plasterboard with Texound 70 glued to it.

It should be noted here that the thermal insulation material attached to the wall can be replaced with Texound FT 75, which has an additional layer of felt.

Third option

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

• The first layer of thermal insulation material is installed on the wall.
• The second layer is the Texound sound-absorbing membrane.
• A sheathing is mounted on top of it.
• Then the insulation mats are installed.
• The last layer on the structure is sandwich panels, consisting of two sheets of plasterboard, 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. A sales consultant will help you make the right choice by determining the thickness and best form of Texound release.

Using foam mats as sound insulation

The most effective affordable material for soundproofing walls in an apartment can be called acoustic foam rubber. Due to its porous structure, this material perfectly absorbs and dissipates sound vibrations.

Acoustic foam rubber is capable of neutralizing two types of noise - sound and vibration waves, that is, it muffles sound and dissipates low frequencies arising from vibrations of surfaces, for example, knocking or “bass” of music.

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

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

Types of material relief

The types of relief patterns of acoustic foam rubber can be different. Both the total thickness of the material and its sound-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 sound insulation 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, most often used in large halls.
"Pyramid"
	For moderate protection of walls against penetration of high and medium frequencies.	Protection against standing waves in small spaces. In combination with traps for low frequencies, they can completely soundproof a room.	Suitable for rooms of any size and used in conjunction with additional elements soundproofing such as sound traps.	Same characteristics as wedge material type

There are other, less commonly used elements made of acoustic foam.

Name of relief type	Characteristics
"Peak"	This mat relief 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"	Low-frequency waves are more difficult to dampen because they are longer. For this purpose, bass traps are installed in each corner of the room, which are designed for rooms of any size.
"Treble and Mid Frequency Traps"	These elements are installed in large halls. They are designed to capture mid and high frequencies, and create a low frequency diffusion effect. They are installed in a vertical position, but if the blocks are cut in half and installed in the corners, they will become low frequency traps.
"Corner block"	Corner blocks are produced in the form of a triangular beam. They are installed in the corners of the room and at the junctions of two surfaces, and also serve to dissipate low frequencies.
Decorative ceiling tiles	They are produced with or without a relief pattern. They are designed to change the relief and shape of the ceiling, thereby achieving an additional soundproofing effect.
Insulating wedges	Used to reduce vibrations from studio equipment and used as a substrate for 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 are choosing foam rubber to reduce the sound conductivity of the walls. Thanks to its high sound-absorbing and dissipating properties, this material can make a room almost completely soundproof, provided it is installed 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 any of its soundproofing qualities when it is covered with plasterboard. The main condition in creating such a structure is that the foam mats themselves must be glued directly to the base of the wall, without any lining.

Soundproofing walls with acoustic foam

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

Installation work is carried out in the following sequence:

• To make the foam stick easily, it is best to prime the wall surface and dry it well.
• Next, the mats need to be fixed to the wall. They must fit tightly to its surface, otherwise the sound insulation effect will be partially lost.

• You can glue foam mats using 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 frame sheathing from metal profiles or wooden beam. The frame guides are mounted at a distance of 50÷60 mm from the wall.
• The racks are mounted in the recesses of the relief pattern directly to the wall. Holes for fastenings are drilled directly through the foam.
• After fixing the frame of the sheathing, sheets of plasterboard, plywood, PVC panels or others are fixed to the guides finishing materials. This will not in any way reduce the sound absorption efficiency of the foam layer, since it will be the first to receive all sound waves coming from outside, absorb them and dissipate them.
• In the same way, the foam rubber is mounted on the lathing. The lathing is installed directly on it, and then one of the types of suspended ceilings is fixed.
• On the floor, logs are laid on top of acoustic foam rubber, on which a plank or plywood floor is laid. Further, if desired, laminate, linoleum, carpeting or other decorative covering can be laid on the plywood.

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

The exposed material will require frequent cleaning with a powerful vacuum cleaner to prevent large amounts of dust from accumulating within the porous material. If one of the panels comes away from the wall for some reason, it can be quickly and without special preparation glued into place.

In addition to the considered soundproofing materials, the range includes construction stores others are presented. But today, acoustic foam rubber, Texaund membranes, Schumanet slabs and similar sound insulators can be called the most effective and safest for installation in an apartment.
