Today, during renovations, many people prefer to make partitions from plasterboard. Such designs are gradually replacing other technologies for arranging non-load-bearing partitions. It should be noted that when creating plasterboard partitions You also need to worry about sound insulation. This will maximize the protection of the room from the penetration of extraneous noise from the outside.
This material itself has a certain soundproofness, but it can be significantly increased by:
- soundproofing materials, which the company produces in a large assortment Knauf;
- soundproofing option for wall cladding;
- mounting the structure with special elastic soundproofing fasteners;
- fastening of special profiles;
- increasing the distance between rack profiles;
- increasing the thickness of the frame;
- increasing the thickness of the facing layer;
- filling the frame with special materials.
Soundproofed plasterboard partitions
Thanks to the use of these possibilities, the sound insulation of a plasterboard wall will be of the highest possible quality.
In order for the sound insulation of a partition made of plasterboard to be maximum, you need to select special sheets for installation. The Knauf soundproofing sheet has proven itself to be excellent in this regard. You can also use Aku-Line plasterboard sheets from Giprok. These sheets perfectly reduce the level of noise penetration when used for finishing internal partitions, as well as wall and ceiling cladding. These two manufacturers are the most popular in the soundproofing market. It will cost a little more to buy sheets from the Knauf company, which will cost about $12 per piece.
In its structure, acoustic plasterboard is a sheet with frequent holes. Due to this, the volume is reduced when sounds directed at the surface of the walls are reflected.
In addition to the holes, such drywall contains a non-woven fabric, which is glued to the underside of the panel. It prevents sound from spreading inside the partition.
Besides plasterboard sheets The following materials are used to dampen noise:
- expanded polystyrene. It is widely used in Knauf TIGI systems. It has the appearance of a foamed hard thermoplastic, which consists of fused granules. These granules have cavities filled with air. Thanks to this, the material has excellent properties in terms of sound and heat insulation. Today, expanded polystyrene is made in two ways - with or without the addition of a fire retardant. The presence of a fire retardant in the composition makes it possible to increase the material’s resistance to high temperatures;
- mineral wool slabs. This material also has high noise insulation. The Knauf company makes excellent products. They can also be used in the company's TIGI systems.
Knauf soundproofing boards are produced in a wide variety of lengths (from 90 to 500 cm) and widths (from 50 to 130 cm). In this case, the thickness of the layer can be from 2 to 50 cm. Most often, slabs 4 cm thick are used for soundproofing walls.
Thanks to these materials, the sound insulation of plasterboard partitions will be excellent. Using Knauf systems you can easily achieve complete sound insulation.
Materials used to fill partitions
Once you have decided on the choice of soundproofing sheets, you need to think about the internal filling of the partitions. Properly selected materials in this case will increase soundproof layer.
To create a noise-absorbing layer, you can use the following materials:
- special membranes. They have the appearance of a thin polymer fabric, which is covered with a layer of felt fibers. The layer thickness can range from 2.5 to 12 mm. This allows the use of such material even in the thinnest partitions, while maintaining high sound insulation properties. The most popular membranes today are Texound brand membranes;
- sound-absorbing boards;
- various porous materials. Thanks to their pores, they can effectively absorb sound.
Soundproofing plasterboard walls is possible using the following materials:
- acoustic mats. They are panels made from stone wool. The homogeneity of the slab helps dissipate sound waves. Are environmentally friendly pure material. The most popular mats are from the Rockwool company;
- slabs made from fiberglass. The most popular products today are those of the Knauf company (Insulation). It is worth noting that the price for such a stove will be slightly more expensive than other manufacturers. But the material does not rot, does not get wet and is practically not subject to combustion;
- elastic materials that are placed between load-bearing structures. They allow you to reduce the sound of impacts;
- polyurethane foam and polyester panels. This material can be used both for internal filling of partitions and for constructing false walls. But be careful, they may contain substances that cannot be used in a residential area, as they are flammable.
Note! To achieve good soundproofing of a plasterboard wall, you can use most materials made on the basis of mineral wool. However, it is recommended to choose only those materials that are specifically designed for sound absorption.
Sometimes it is recommended to use foam plastic as the internal filling of plasterboard walls. But it copes very poorly with sound insulation. Foam can reduce the volume of noise, but does not eliminate it. Therefore, in this situation it will be ineffective.
Soundproofing drywall is also possible using special sprayers. The basis for spraying is cellulose fibers, which are impregnated with a special adhesive composition. A soundproofing coating is formed due to the spraying of this composition specialized installations. Here it is possible to control the thickness of the applied layer, making it thinner or thicker, depending on need. The most popular composition, which today is used to improve the soundproofing characteristics of a structure, are mixtures of the Sonasprey brand. With their help, you can process not only the walls outside, but also the inside, as well as ceilings and niches.
Carrying out installation work
Soundproofing drywall during the construction of partitions is easy to do with your own hands. Installation work When installing plasterboard walls, we always start with fastening metal frame.
Installation of the frame in in this case practically no different from the construction of an ordinary false wall. But still there are certain nuances in the work:
- We start by creating markings on the ceiling, wall and floor. Here you need to use a laser level. This way you will be able to create an impeccably even structure;
- We cut profile guides for the base of the frame. To increase sound insulation you can use wooden beams;
Frame base
- the starting profile must be fixed to the ceiling and floor. Self-tapping screws are used for fastening;
Note! It is best to use specialized polymer fastening units rather than standard dowels.
- different from standard design is that it is necessary to place cut strips of elastic material between the supporting structures. The most commonly used is “Vibrostack”; its analogues are also allowed;
- if necessary, hangers should be used. The most commonly used hangers are the Vibrostek-KS models. Such models or their analogues contain polymer inserts and contribute to better sound insulation;
- Next we make vertical fastenings. The larger the step between them, the higher the sound insulation will be;
- all fastening points, as well as holes, must be processed silicone sealants. This treatment will help reduce vibration noise. Can't be used here polyurethane foam, since it does not help reduce sound transmission, but is very flammable.
Filling the frame and covering it
When the frame is completely ready, you can start filling it. To make this more convenient, one side can be immediately covered with plasterboard, which will prevent the soundproofing material from falling out.
Section of frame covered with plasterboard
Filling the frame involves:
- carrying out all communications: wires, pipes, electrical wiring, etc.;
- All wiring is placed in special plastic casings. Pipes should be wrapped in polyurethane covers;
- Next we lay the noise-absorbing material. It should be laid in such a way that there are no voids left;
Laying soundproofing material
- If necessary, install a sound-absorbing membrane on top of the material. Instead, you can use porous tape from Vibrostek.
After everything inner space The partitions will be filled with soundproofing material; the remaining side can be covered with plasterboard.
To achieve greater insulation of the structure from noise, it is necessary to use a double layer of plasterboard sheets. This is very easy to do - we attach a second one on top of the plate attached to the frame. Remember, the seams on the second layer should be offset in relation to the first by at least 20 cm. The entire sheathing will also need to be treated with sealant. Seams can be sealed with reinforcing tape.
Sealant treatment
On finished wall Fugenfüller putty is applied. If reinforcing tape was not used, Uniflot putty will do. Both putties have proven themselves equally well.
As you can see, you can make a partition from plasterboard with increased sound insulation with your own hands. The main thing is to strictly adhere to the technology.
Do you sleep poorly and feel discomfort? Have you become irritated for any reason? Best materials for noise insulation for an apartment will help you cope with your problems and create conditions for good rest.
The reasons for poor sound insulation are:
- inadequacy of the construction of the house to the norms and standards;
- faulty fences. Voids and cracks reduce sound insulation;
- noise beyond measure in neighbors' apartments or from the street outside.
Every owner of an apartment or house makes every effort to solve the inconveniences of everyday life and protect themselves from unnecessary noise. Sound insulation is required to create comfortable living conditions, both in your home, and to avoid conflicts. Active children's games, home cinema, musical instruments - a partial list of objects and related activities for scandals.
To decide on the choice of raw materials, it is necessary to determine the type of noise.
There are:
- Air. Sounds transmitted from outside by air: busy traffic, deafening music, industrial plants.
- Shock. Drilling walls, driving nails during repairs. However, specially designed insulation is necessary when carrying out systematic work using a jackhammer.
- Structural. The road transmits vibration to the walls of the apartment, converting it into decibels.
Attention! The noise from the highway reaches 70 dB.
Soundproofing materials absorb sounds from outside or prevent them from spreading from the apartment. You need to find a suitable material for the interior of the room.
What to look for when choosing sound-absorbing material for your home?
When carrying out noise insulation work, the following should be taken into account:
- Room dimensions.
For small rooms - a children's room or bedroom - a plasterboard sheet is suitable, which will not reduce the usable area. In spacious rooms, sound-absorbing multilayer structures are installed in a special frame, occupying a lot of space. Styrene, mineral wool or kraft cardboard.
- Purpose of the room.
Materials suitable for bedrooms should not be used in the kitchen, which is characterized by high humidity and temperature fluctuations. Select sustainable insulating materials.
- Invoice.
Its use in houses made of monolithic concrete different from frame buildings. The quality of sound insulators depends on the price.
- Invoice quote.
It is necessary not only to correctly combine sound insulators and soundproofing materials, but also to take into account their quality properties. The purpose of the invoice is interior decoration premises, therefore substances harmful to health are excluded from the composition: bitumen and lead, mercury and formaldehyde, volatile resins, EPDM compounds and volatile resins.
- Sealing joints and cracks.
Integrity and solidity are required in structures. Therefore, all unnecessary holes and holes are eliminated. Unsealed connections, uninsulated air pipes, risers and sockets reduce sound insulation. Sealing joints with soft mastic or sealant.
- Qualified installation.
To achieve an effective result, proper installation is required. Qualified sound insulation, repair and finishing workers will come to the rescue. It is important that sound insulation based on design ideas matches the interior of the apartment or house and does not interfere with utility lines.

Sound insulation of walls
Before work, inspect the wall and seal cracks and cracks. The fastest and convenient way- rub it with cement. Pull out electrical outlets and check for voids. If necessary, fill with mineral wool and seal the hole with putty or cement before putting the socket in place.
Soundproofing material and installation methods are selected based on price, efficiency and quality of sound insulators, as well as the amount of usable space consumed.
A variety of textures are used for decorative sound insulation of walls. The construction services market provides a wide range of products. Particularly popular among consumers:
- drywall;
- soundproofing panels;
- roll material.
Video instructions for working with ZIPS panels when soundproofing walls:
Drywall installation
Assembling the frame. If the walls are thin, attach the profile to a rubber lining. Mineral wool or other material as a sound absorber is placed in the prepared sheathing. The structure is covered with plasterboard sheets. They putty and finish.
Assembling the soundproofing panel
With a perfectly even coating, the panel is installed directly on the wall. Fastening with a notch-protrusion lock or with construction adhesive. The problem of leveling the wall covering is solved in two ways: by assembling the frame, as is the case with mounting drywall or putty.
Installing the panel is quite simple. No finishing is required as the surface coating is available. A variety of materials and colors: paper trellises, fabric, wood or stone lamination.

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 interior partitions is an 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.
It itself has a high level of 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 sound from 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 to this, with reverse side A non-woven fabric with a sound absorption function is glued onto 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 can 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.
The ability to spray cellulose foam on various surfaces eliminates the need to install a frame that 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 structures. 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 also use large fences with acoustic decoupling in the junction areas.
- Placing noisy equipment in rooms with partitions. The effectiveness of noise reduction materials has limits. It's not always possible to create high-quality protection from sounds. 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, and also fill the joints with special sealants.
- Soundproofing buildings with thin soundproofing screens. A soundproofing 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 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.
Modern ideas about the ergonomics of working and living space, current trends in interior design require the most open layout of premises, good levels of lighting, ventilation and sound insulation.
The problem of reducing noise levels in buildings has become particularly relevant in last years. In large cities there are a huge number of noise sources: transport, machinery, equipment create an uncomfortable environment and interfere normal operation and people's recreation. Traditional walls and partitions installed in rooms do not meet modern requirements for comfort: they take up a lot of usable space, have high sound permeability, degrade illumination, and interfere with ventilation.

When starting a renovation, owners sometimes plan to divide a room that has large area. In the newly formed room you can arrange a study, a nursery or a bedroom. At the same time, you need to think about protecting the resulting premises from noise, because peace and quiet is one of the factors for comfortable relaxation or productive creative work. Choice optimal option Soundproofing interior partitions will give the desired effect and increase the comfort of family living.
As you know, the thicker the wall structure, the greater the sound insulation value it is characterized by. However, a rational approach is to design a structure that will provide maximum level sound insulation with the smallest parameters of thickness and mass of the partition. Thus, there are three ways to reduce the noise level:
- increase the massiveness of interior partitions;
- use sound-absorbing materials in the design;
- seal the intended penetration paths of sound waves.
Interior partitions: designs and materials
Partition structures are divided into two groups:
- single-layer;
- multilayer.
Single-layer walls dividing the interior space of the house are made of various dense, homogeneous building materials, which are rigidly bonded together with mortar. It could be bricks, blocks, tongue-and-groove slabs, expanded clay concrete. The sound insulation parameters of each material depend primarily on the mass, and to ensure the desired level of this indicator, the thickness of the wall can be increased. However, this approach increases the load on the floor and foundation and reduces, albeit slightly, the area of the room.
If we recall physics, then sound waves, while propagating, encounter an obstacle (partition) on their way and are reflected or refracted. Porous structures are capable of absorbing waves that are scattered in the depths of the material. Therefore, preference is often given to multilayer partitions consisting of at least two or three layers.
In this design, materials of different structures alternate: dense and light. They differ significantly in characteristics and are not strictly connected to each other. The former, for example, represented by brick or plasterboard, have a high reflection coefficient and perform a soundproofing function, the latter - soft (mineral wool) carry out sound absorption. Such a union is effective and creates optimal conditions to protect premises from noise, since one layer of the structure reflects the sound wave, the other absorbs it.
To compare the characteristics of different materials, an indicator such as the sound insulation index of partitions is used. SNiP regulates the soundproofing of interior partitions in one apartment. This parameter is at least 43 dB.
However, as practice shows, recently the number of powerful noise sources has increased significantly: home theaters, air conditioners, hoods, etc. Appliances. Increased background noise does not contribute to comfortable living and it is advisable to arrange interior partitions, bringing the sound insulation index of the structure to at least 50 dB.
How to soundproof a plasterboard partition
Drywall is a material that conducts sound well, so the thickness of sound insulation is recommended to be at least 15 cm and multi-layered. Work begins with installing a frame under a partition made of metal profile: vertical posts, guides, stiffeners and sheathed with sheets of plasterboard. On the other side of the casing, a similar frame is mounted; their independent installation, which does not provide for a constructive connection, will prevent the formation of sound bridges with the opposite surfaces of the partitions.
Next, soundproofing material is laid. These can be insulating membranes, the popular Izover or the usual mineral wool. And the sheathing is done again sheet material. When soundproofing plasterboard walls, anti-vibration tape is used; its use will contribute to the protective function of the structure from noise.
Treating drywall with antiseptic agents and primer is an important step in the process of making partitions; it will ensure the reliability and longevity of the newly constructed interior wall. Further work involves filling, grouting and decorative finishing designs.
When performing soundproofing of frame partitions, other materials have also been used. A striking example is the acoustic triplex Soundline-dB. It consists of two gypsum fiber sheets, they are weighted and have high moisture resistance. Each of them is 8 mm thick, they are connected using a layer of special sealant characterized by elasticity. The material is used for soundproofing frame-type partitions.
Choosing a material for soundproofing partitions of a wooden house
Wood is a traditional and favorite material of Russian developers. Therefore a huge number country houses It is built from logs and beams. As for partitions inside a building, they are extremely rarely made from logs, since such a wall not only weighs down the structure of the entire house, but also takes up part of the usable area.
They are most often made from frame panels, timber, or boards. Wood conducts sounds well, so if you don’t worry about soundproofing wooden partitions, then every sound will be clearly audible in the next room, and even a quiet creaking will disturb you.
The most common and effective option It is considered a frame structure of partitions, consisting of several layers, like a pie. Used for cladding wooden lining, panels, fiberboard, plasterboard, and as an internal soundproofing layer - fiberglass, mineral wool and other materials.
How to soundproof tongue-and-groove partitions
Tongue-and-groove slabs are another building material that is often used in the installation of interior interior walls. The panels are produced on a gypsum basis; they themselves have a good noise insulation coefficient - 42 dB (with an 8-mm thickness of the product). But still this is not enough.
Additional sound insulation is performed using materials with a noise-absorbing effect. These are special membranes that are glued to the surface of the slab, securely fixing it. Any construction sealant can be used as an adhesive. To increase the level of protection of the room from noise, the membrane is attached to both sides of the partition. Thus, they achieve an increase in the sound insulation coefficient by almost 30 dB.
In ensuring sound insulation of premises, the primary role is played by the choice of material and the competent implementation of the appropriate set of works. But do not forget that only sound insulation of plasterboard or wooden partition will not give the desired effect. It is advisable to take measures for sound-absorbing treatment of external walls; if the room has a window facing the street, take care double-glazed window, good adjustment of fittings.
