Silence in the apartment is the key to healthy sleep and not frayed nerves. But achieving complete silence in a modern apartment building is very difficult. To get rid of noise, you need to carry out a set of works to partially or completely soundproof your apartment, and this requires significant financial costs and time. But if the desire to live in silence is more important to you, then we advise you to read our article, from which you will learn how to isolate your apartment from extraneous noise and what materials to use.

Before we begin soundproofing an apartment, let's understand the types and sources of annoying noise. After all, to get rid of noise, sometimes it is enough to isolate a certain element of the apartment’s structure and not spend money on complete sound insulation.

There are two types of noise:

• Wave noise - transmitted through the air, from the source to the eardrums, using sound waves. Wave noise includes loud music, loud conversations, barking dogs, and so on.
• Vibration noise– transmitted by vibrations along the walls emanating from the source. Vibration noise includes a sledgehammer hitting a wall, the operation of a hammer drill or a washing machine.

Now let's look at the sources of noise:

• Noise from the street comes mainly through the windows. The sound of squealing brakes, the voices of screaming children and grandmothers, the hum of a flying airplane - all this is noise coming from the street. You can get rid of street noise by installing high-quality windows with triple glazing. Curtains made of thick material can serve as an additional soundproofing element.
• The noise from the entrance comes through the front door. In order not to hear the sounds of a working elevator or neighbors arguing on the landing, it is enough to soundproof the front door. In addition to covering the door with sound-absorbing materials, it is necessary to install seals between the door leaf and the frame, otherwise noise insulation will be ineffective.
• Noise from adjacent apartments– enters through walls, through sockets and cracks between floor slabs. Noise from neighbors is the most common reason for wanting to soundproof an apartment. If there is only one source of constant annoying noise, then it is enough to soundproof the walls adjacent to the source. If you are unlucky and noisy neighbors surround you on all sides, then in this case you will have to completely soundproof the apartment.
• Noise from your apartment– approaches neighbors in the ways listed above and annoys them. If you often have noisy groups, if you are a musician rehearsing at home, if you have children who love to jump and have fun loudly, then for the sake of maintaining good relations with your neighbors, it is better for you to soundproof the walls, ceiling and floor without waiting for the visit of the local police officer.

Soundproofing methods

Soundproofing walls, ceilings and floors is done in three ways:

• • Frame - this method involves installing guides on the wall for installing cladding panels. Sound-absorbing material is placed between the guides, after which sound-reflecting panels are installed. In some cases, for example in recording studios, panels have a surface that absorbs sound rather than reflecting it.
    The advantage of this method is the high quality of sound insulation, but the disadvantages are the high cost of work and the reduction of usable space in the room.

• • Installation of slabs and membranes– in this method, soundproofing material is installed or glued directly to the wall, floor or ceiling. After which the slabs and membranes are plastered or covered with thin panels.
    If the technology for installing slabs or membranes is correctly followed, the quality of sound insulation is not inferior to the frame method, and the financial costs are significantly lower.

• “Floating” - this method is used only for soundproofing the floor. The insulating material is spread on the floor and covered with a waterproofing layer. A reinforced screed is made on top and a floor covering is installed. The advantage of this method is the absence of rigid fastenings, which helps to significantly reduce vibration noise.

Soundproofing materials

Soundproofing materials come in the following types:

Soft insulation

Soft sound insulation includes materials made from different types of fibers sold in rolls:

• • Soundproofing membranes– there are self-adhesive and regular ones, made from synthetic and natural fibers. Used for walls, ceilings and floors. Separately, for floor insulation, membranes are produced from bitumen polymers with a layer of polyester felt.

• • Needle Punched Fiberglass Material– Used for finishing walls and ceilings. Insulation is well suited for frame structures.

• • Polyester fabric backing– made specifically for “floating” floors, excellent as a substrate for laminate flooring.

• Mineral wool- a simple and affordable heat and sound insulation material used in the frame insulation method.

MaxForte SoundPro

A new generation material, created taking into account theoretical developments in the field of building acoustics and practical experience in installation work. With a minimum thickness of 12 mm, the material provides maximum protection against airborne and impact noise and is indispensable in small apartments, where every centimeter counts! Completely environmentally friendly: does not contain adhesives or other chemicals. MaxForte-SoundPRO - ideal for any premises: apartments, kindergartens, schools. The material also acts as fire protection (completely non-flammable) and thermal insulation!

MaxForte EcoPlate 60

The material MaxForte-ECOslab is made of 100% volcanic rock (without impurities, slag and blast furnace waste). MaxForte-ECOslab has excellent acoustic properties, which allows this product to be successfully used for soundproofing the most acoustically complex objects: multiplex cinemas, recording studios, listening rooms, home theaters, etc.

The material is produced on modern equipment from SIMA (Italy); exclusively primary raw materials are used in production. EcoAcoustic is completely safe for human health: the slabs do not emit or contain harmful substances!

Sealant MaxForte

MaxForte sealant is intended for sealing seams, joints, holes in soundproofing walls and ceilings, as well as in the construction of “floating” floors and floors on joists. Due to its low modulus of elasticity, the sealant has excellent vibroacoustic properties and provides a significant reduction in the vibration load between building structures, acting as a damping layer.

VibroStop Pro

Vibration-isolating mount designed to combat impact noise penetrating floor slabs and walls. The use of VibroStop PRO can significantly reduce the vibration load on the profile and provide additional sound insulation of the ceiling and walls at a level of 21 dB.

MaxForte Shumoizol

The rolls are spread with the soft side on the floor, the edges are placed on the walls. After work, all excess can be easily cut off. The joints between the rolls are coated with MaxForte Hydrostop liquid rubber.

Advantages:

1. Impact noise level reduction 27 dB.
2. The material does not tear or crack during installation, due to the addition of imported plasticizers to the composition.
3. Can be used as waterproofing, the material is waterproof.
4. The material can be used for dry screed and under laminate.

MaxForte SoundPro

Installation is carried out by analogy with Shumoizol, the edges are placed on the walls, the rolls themselves are overlapped by 5 cm, and the joints between them are coated with MaxForte Hydrostop liquid rubber. Next, a construction film is laid, this is done so that the screed solution does not penetrate into the sound insulation layer.

Advantages:

1. Impact noise level reduction 34 dB.
2. Reduction of airborne noise level 10 dB.
3. Rolls are resistant to moisture. Not subject to rotting.
4. Belongs to sound absorption class “A” out of five possible.
5. The material does not attract rodents.

MaxForte EcoPlate 110 kg/m 3

To begin with, MaxForte tape is laid around the perimeter in two layers. The slabs are placed on the floor close to each other and covered with construction film.

Advantages:

1. Belongs to sound absorption class “A” out of five possible.
2. Completely non-flammable material.
3. Does not contain phenol resins.
4. Due to the optimally selected density of 110 kg/m3, the screed does not spring and will not burst over time.
5. Sound insulation at 36-38 dB.

If it turns out that the apartment already has a screed, or it is an old housing stock where the ceiling simply cannot withstand the heavy weight of the screed, an effective option is a floor on joists.

Solid insulation

The type of solid sound insulation includes simple slabs and combined panels made of sound-absorbing materials:

• • Combined panels– represent a structure of two sheets and a layer. Sheets are made from particle board, cork or synthetic materials. Quartz sand and mineral wool are often used as a layer.

• • Basalt slabs– made from basalt fiber. Additionally, the boards can be treated with a water-repellent composition.

• • Polyester fiber boards– synthetic sound insulation, easily cut to required sizes, widely used in frame construction.

• • Staple Woven Fiberglass Boards– designed for filling interprofile spaces, insulating suspended ceilings and frames installed on walls.

• • Cork slabs are made from the fibers of the cork tree. Wall panels and cork laminate can be installed without additional soundproofing materials.

• Foam boards- the cheapest and most widely known material for sound insulation. Foam boards are inferior in sound insulation quality to more modern materials, but due to their affordable price, they remain a popular option for budget renovations.

Handy sound insulation

Few people know that some interior items can serve as good sound absorbers and reduce noise levels by 20-30 percent:

• • A large rug - placed on the floor or hung on a wall - can significantly reduce the level of incoming or outgoing noise.

• • Furniture wall– installed along a wall shared with your neighbors, will relieve you of loud noise, turning it into a soft hum.

• Curtains made of thick material– are able to muffle sounds coming from the street.

Soundproofing walls, ceilings and floors

Technologies for soundproofing floors, walls and ceilings differ from each other, therefore, we will consider each process separately.

Soundproofing the floor

Floor soundproofing is done to block noise coming from the apartment located on the floor below, or vice versa, so that the noise produced in your apartment does not annoy neighbors from below. To insulate the floor, you can use the “floating” floor method, or make a frame from logs.

In the first option, you need to spread soundproofing material over the entire surface of the floor, then make a concrete screed. After this, a laminate or other type of flooring is laid on the screed. In the frame method, it is necessary to make a sheathing from wooden blocks (lags). Insulating material is laid between the joists, the field of this sheathing is covered with chipboard or boards. To reduce vibration noise, it is recommended to place special vibration-damping pads under the joists.
Detailed article.

Soundproofing walls

You can block sounds coming from the apartments of your neighbors on the floor by soundproofing the walls adjacent to them. Please note that it makes no sense to insulate all the walls in the apartment, including internal partitions.
To insulate walls, you can use self-adhesive soundproofing membranes, combined panels or slabs installed in a special frame. Keep in mind that the thicker the soundproofing layer, the less usable area of ​​your apartment will remain.
Another important factor in soundproofing walls is pass-through sockets. In order to block sounds coming through them, you need to fill the empty space between yours and your neighbor's socket with soundproofing material, such as polyurethane foam.
Detailed.

Ceiling soundproofing

To soundproof the ceiling, it is better to choose lightweight materials that will not peel off due to their own weight or heavily load the ceiling frame.
If you already have a suspended ceiling installed, then you simply need to remove the panels and install insulation on the main ceiling, then install the panels in place.

Remember the “golden” rule - soundproofing is much easier and cheaper to do before finishing work than after the renovation is completed!

Do you sleep poorly and feel discomfort? Have you become irritated for any reason? The best soundproofing materials for your 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 differs 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 texture is interior decoration, 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.

Soundproofing for ceilings

Often gluing a roll of insulation is not enough. Cork wallpaper or tiles will help solve simple problems. To soundproof the ceiling, you will have to sacrifice the height of the apartment. The most effective technique is to build a ceiling structure.
There are:

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

Practical video tips on installing ceiling sound insulation with your own hands:

Sound insulation of walls

Before work, inspect the wall and seal cracks and cracks. The fastest and most convenient way is to grout 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.

Pasting of roll sound insulators

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

Sound insulation for partitions

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

Soundproofing for a summer residence

Which company is better to choose? Will the purchase affect the family budget? Will it completely solve the problems of sound insulation? Consumers are looking for answers to these questions before choosing a quality texture for a country house. It is impossible to answer unequivocally, since each material has its own quality characteristics, advantages and disadvantages, and cost.

To avoid mistakes when choosing a product, you should take into account the suitability of the material for the intended purpose: absorption of airborne or impact noise. The first type corresponds to materials with a fibrous or granular base.

Advantages:

• inexpensive;
• light weight;
• easy to install.

Soundproofing structures prevent extraneous noise from entering the apartment.

carrying out work

When furnishing their apartment, the owners try to ensure maximum living comfort. Many modern buildings do not have good sound insulation (however, houses from the 80s and 90s cannot boast of this either). Therefore, certain measures are being taken to soundproof the home. At the same time, you need to pay attention not only to the walls, because sound insulation for the ceiling is also very important.

From theory to practice

The main indicator in this case will be the efficiency of sound absorption.

Note that all noise and extraneous sounds are divided into:

1. air;
2. drums.

Impact sounds - those arising from mechanical action, air sounds - everything that is emitted: screams, loud music, barking dogs. Therefore, when choosing, you should pay attention to the above first.

Common Methods

Undoubtedly, the most popular method is over which materials are laid.

The material in this case becomes:

• polyurethane foam– block or sprayed onto the surface (the second option is considered one of the most effective;

• cork;

• coir;

• mineral wool;

• All kinds of panels made of mineral and organic fiber.

Such a device is associated with additional work - in particular, with the installation of an auxiliary system. Systems can be in different formats:

• Hemmed(the metal frame is installed on the ceiling; the frame is sheathed with sheets of plasterboard);

• (film or fabric coverings are stretched onto special brackets);

Above the cassette ceiling

• (soundproofing panels for the ceiling are laid on a metal frame).

Cork

There are many fans of cork materials today. This material provides excellent sound insulation from impact noise.

• In terms of level, only 2.5-3 cm of cork material replaces 10-15 cm of reinforced concrete slab and 10 cm of pine timber. The noise level with a thickness of 3 cm of balsa wood is reduced by approximately 20-45 dB. Therefore, a single-layer soundproofing flooring with a thickness of 10 mm is not enough.
• It is assumed that a layer of technical cork approximately 3-4 cm will be created, which will be covered with insulation on top (if required) and sheathed with decorative trim. In this case, the quality increases several times.

Professional sound insulators

The name speaks for itself - these materials are created to successfully absorb any noise coming from the room located above.

Mineral wool boards

Excellent soundproofing characteristics are shown by ceilings made using mineral wool slabs. In this case, the sound absorption coefficient is about 85%.

The technology here is quite simple:

• The necessary frame structure is fixed to the rough ceiling, which is clogged with mineral wool slabs;
• Next, the frame is sheathed with plasterboard sheets;
• Finally, soundproof ceilings are finished with any desired material (applying putty, paint, wallpaper).

Advice! The method is quite effective, but has one very serious drawback: in total, the thickness of the entire structure will reach 15 cm (maybe more). It cannot be said that this is the best soundproofing of the ceiling, but installation of this type is the right decision, and the price is affordable.

Soundproofing sheets

At a professional level, soundproofing ceilings are made with special fabrics. What advantages does a branded foreign gasket have over traditional mineral insulation materials that are used everywhere?

• Most materials belong to the class of slightly flammable and completely non-toxic, so they are used not only in residential premises, but also in public places: restaurants, bars, clubs, cinemas;

• Such materials are very easy to install. It is enough to remove the protective layer and glue it to the prepared base;
• According to the European classification for noise absorption, such soundproofing ceiling panels correspond to the BFT class (the highest);
• The canvas is a membrane in which the sound “gets stuck”. It can be made from various materials: high-quality rubbers, felt and others.
• To produce the membrane, felt is used, which is a good sound absorber;

• When the wave reaches the ceiling, the polymer will reflect the sound. But the felt will absorb the remnants of the shock wave without reaching the room;
• Soundproofing materials for this type of ceiling have a thickness of 2.5 to 14 mm, so they will not conceal the ceiling space.

Shumanet BM slabs

In many construction and repair companies, sound-absorbing ceilings are installed using Schumanet BM acoustic slabs. In the modern construction market, these slabs are one of the best and highest quality materials for sound insulation.

Plates are widely used for finishing suspended ceilings in apartments, cottages and country houses.

• The manufacturer's instructions note that the material is absolutely non-flammable (a very important factor for many types of premises);
• Standard noise absorption coefficient – ​​0.9 NRC;
• The slabs are subject to quality control by installation companies.

Schumanet BM slabs are fixed to the ceiling tiles using plastic “mushrooms”. This ensures high-quality fastening of the slabs in any conditions. After this, soundproofing suspended ceilings or other types of products (suspended, suspended) are mounted on the slabs.

Complex systems

In the Russian construction market, many companies offer clients the installation of a comprehensive soundproofing system, which includes 2-3-4 different materials.

• In addition, many people install the material themselves. In this case, people resort to a combination system, i.e. A sound-absorbing membrane is mounted on top of the sound-absorbing slabs. Such a system will have an extremely high sound absorption coefficient.
• Not so long ago, special slabs began to appear in stores that can be installed on top of the existing ceiling system. Such soundproofing materials for the ceiling have a serious advantage: they absorb sound from the noise coming from the owners’ premises. Thus, the owners of this solution eliminate unnecessary noise and neighbors.

Dropped ceilings

Drywall installation

Soundproofing a suspended ceiling involves attaching a hollow slatted structure to the rough surface, which is subsequently filled with sound-absorbing material. After this, cladding is carried out with a decorative coating. Sometimes soundproofing grilles or perforated drywall are attached to the ceiling.

A frame of this type is mounted from a standard metal profile for plasterboard ceilings.

But there are some features here:

• The effect of sound absorption will be directly related to the size of the internal cavity of the ceiling, which is filled with the material. Therefore, it is necessary to calculate the distance from the floor slab to the external cladding, taking into account the thickness of the sound-absorbing materials used. You need to understand that the installation of such a system will certainly lead to a significant reduction in the overall height of the room, which will be very noticeable in ordinary apartments;
• The outer part of the structure is a diffuser, a membrane that relays sound vibrations, especially impact noise when it is rigidly attached through a supporting frame to the walls and ceiling. To avoid this, during the installation process it is necessary to prevent extreme hard contact of the metal frame with the walls (a gap is left) and the rough ceiling (soundproofing fasteners and linings are used). This ensures sound insulation of the ceiling from impact noise;

Suspensions "Vibrofix P"

• During the installation of a soundproofing structure, care must be taken to ensure that the system is completely sealed. Even small, barely noticeable cracks and holes will allow sound to pass through.

Conclusion

If you plan to get the highest quality result, then it is recommended to pay attention to the cork and complex systems. But you need to keep in mind that such a device will be quite expensive financially.

To obtain a high-quality result at minimal cost, you can use mineral wool or glass wool, which is placed in the space between the rough and suspended ceiling.

Soundproofing the ceiling - videos and photos of this process can be found in large quantities on the Internet. Installation of this type can be done either with your own hands or with the assistance of specialists.

Ecology of consumption. House: The “cardboardness” of many domestic buildings has long become the talk of the town. To prevent neighbors from above from bothering you with the details of their everyday life, it is recommended to arrange at least basic sound and noise insulation of the ceiling. And how to do this correctly for tension systems - we will tell you in today's instructions.

The “cardboard quality” of many domestic buildings has long been the talk of the town. To prevent neighbors from above from bothering you with the details of their everyday life, it is recommended to arrange at least basic sound and noise insulation of the ceiling. And how to do this correctly for tension systems - we will tell you in today's instructions.

Types of noise and methods for eliminating them

In the context of construction and renovation, noise is divided into two main categories: structural and airborne, the name corresponding to the path of its propagation. The sources of each type of noise also usually differ. Airborne - this is music, the human voice, the sounds of animals and working household appliances. Such noise is neutralized by damping air vibrations in a layer of porous, easily compressible material.

Structural noise, otherwise called impact or structural noise, occurs when there is intense impact on various parts of the building structure. Examples of such noise include the rattling of a washing machine, the clicking of heels, although the most notorious is still the noise from an impact drill or hammer drill. The spread of noise of a structural nature is eliminated with the help of damper inserts at the junctions of one part of the structure with another, for example, between the ceiling and the reinforced belt of the wall.

In addition, in fact, even structural noise is perceived by humans as airborne, that is, at some point the building transmits vibrations to the air. A secondary way of sound insulation can be to dampen this vibration over the entire area of ​​communication between the walls and ceilings and the space inside the apartment, however, this method is considered more expensive in terms of material consumption.

One must come to terms with the fact that it will not be possible to completely eliminate the penetration of noise into the apartment from the outside, just as it will not be possible to achieve complete absorption of sounds arising inside the room. However, it is quite possible to bring the noise absorption of walls to the standards specified in SP 51.13330.2011. Thus, the optimal degree of sound insulation of walls is about 80–90 dBA for low-frequency noise (walking, impacts) and half as much for high-frequency noise (music, voice).

Does a suspended ceiling provide any advantages?

When working with a stretch ceiling, we are faced with a flat canvas enclosed in a frame of a baguette profile. Unlike suspended ceiling structures, the only way to transmit structural vibration is through the connection of the fastening profile to the walls.

The propagation of low-frequency structural noise through the ceiling is prevented by gluing damper tape under the mounting profile. If you don't do this, you can end up with some kind of speaker the size of the entire room. Note that not all frequency ranges will be amplified through the ceiling; for example, high-frequency noise is damped due to the elasticity of the film.

With air noise and structural vibration of the ceiling, the situation is somewhat worse: the tension canvas practically does not interfere with their spread and even enhances it. At the same time, the plane of the rough ceiling remains completely free for installing any kind of sound insulation of any thickness.

Dependence on the type of building

Work to eliminate construction noise must be planned in accordance with the structure of the building. In frequent cases, the most attention is required to the junctions between walls and floors and the specifics of sealing joints and technological cavities. In some cases, you can even come to the conclusion that surface installation of sound insulation will not give the desired effect.

A classic example of this is a panel house with a single-layer ceiling with hollow slabs. In such buildings, acoustic resonance often occurs due to the rigid connection of the slabs to the wall panels. The optimal solution is not soundproofing the ceiling, but cooperation with neighbors above to install their floor using floating technology.

Frame floors without filler can be modified by adding polystyrene chips or sawdust, which will have a good effect on their sound absorption. In some cases, it is useful to re-seal the load-bearing beams in the walls or technological seams. For example, you can install damper pads and inserts made of porous incompressible material.

Selection of sound-absorbing material

In ordinary cases, installing slab or roll materials on the rough ceiling that dissipate air vibrations until white noise forms at an acceptable intensity helps get rid of the noise from neighbors above. In this case, both special composite materials and conventional insulation materials such as mineral wool are used.

Soundproofing the ceiling with mineral wool

The advantages of special materials include their high efficiency, while the disadvantages include their equally high cost. The best damping of air vibrations occurs at the boundary of two dissimilar media, for example, cardboard and mineral wool. A secondary role is played by the shape and size of the cells, the density of the materials and the order in which the layers are applied.

All these principles can be used when making your own noise insulation cake. However, you should avoid the advice of amateurs and understand that materials such as polyurethane foam, EPS, egg trays, cork and other “innovative” noise absorbers do not have any positive effect, and in some cases even worsen the situation.

The most suitable are felt, mineral wool with a density of 40–60 kg/m3, acoustic mineral wool, wool and coconut fiber. Among specialized materials, rolled Tecsound and AcousticWool mats can be cited as the most effective for soundproofing ceilings.

Features of installation of sound insulation

By soundproofing the ceiling when finishing it with tension fabric, you avoid the need to install a frame suspension system that prevents the spread of structural noise. All that is necessary is to attach one or more layers of sound-absorbing material to the rough surface.

The separation of air media should first be ensured, since the direct transmission of airborne noise occurs most intensively. In general, covering the ceiling with cellophane helps, but such actions require caution so as not to disturb the climate in the room. If the ventilation and insulation system requires free gas exchange through the interfloor ceiling, it is necessary to use vapor-permeable membranes.

In general, sound insulation is attached to the ceiling using disc dowels used in a wet façade system. Their length and installation pitch depend on the thickness of the material, its density and ability to retain its shape. It is most difficult to install multilayer insulation, where temporary fixation of the applied layers is required. For these purposes, you can use point gluing or a structure that supports the cake until it is finally fixed.

In one of the most effective ways to absorb noise, a concrete ceiling is covered with two layers of corrugated cardboard with silicate glue, then a temporary support system is assembled from a ceiling profile for gypsum boards. Acoustic wool is laid in rows on the slats in mats of 60–70 mm each, and a felt carpet about 10 mm thick is placed under it. Denser material in the bottom layer allows for better noise absorption and the use of fewer fasteners.

Pairing with soundproofing walls

When installing ceiling sound insulation, it is important not only to tightly join the elements of the insulator itself, but also to achieve minimal interaction with the sound insulation of the walls. A suspended ceiling allows you to build false wall cladding not right up to the ceiling, and you need to take advantage of this advantage.

To be sure that at the corner junction of the wall and the ceiling there will be no space left for the free propagation of airborne noise, the edges of the ceiling sound insulation must be wrapped and brought into a hidden plane just below the level of the tension covering.

If there is a filler behind the false wall that helps absorb sound, you should make sure that its upper open edge is smooth and the ceiling insulator will fit snugly against the wall insulator. No special fastening is required in this place, you just need to achieve a tight laying without air gaps and make sure that the rigid surface of the sheathing is at some distance from the horizontally located insulation layer, that is, does not rest against it. published

Soundproofing the ceiling from neighbors above

From above, through the interfloor ceiling, two types of noise reach us - airborne noise and impact noise.

Airborne noise- These are sounds traveling through the air, sound from a TV, etc.

Impact noise occurs when there is a direct impact on the ceiling - adults’ heels are clicking, children are running, chairs are moving, etc. From the ceiling, sound is transmitted to the walls and radiated into the room below both from the ceiling and from the walls.

The ceiling must have soundproofing properties to protect from noise the rooms located both below, under the ceiling, and above, above it. To protect the rooms below from noise, building regulations establish sound insulation standards for airborne and impact noise for floors. When transmitting sounds from bottom to top, only sound insulation from airborne noise is regulated.

The Code of Practice, SP 51.13330.2011 “Protection from Noise”, establishes the following sound insulation standards for residential floors:

where R w is the index of airborne noise insulation by enclosing structures, dB (decibel);
L nw is the index of the reduced impact noise level, dB.

The actual airborne noise insulation index of the ceiling must be greater than the norm, and Impact noise level index is the opposite, the lower the better.

It should be taken into account that the values ​​of standard sound insulation indices indicated in the table are This is a compromise between the level of sound comfort and construction costs. Obviously, comfort is sacrificed to the construction budget.

I recommend focusing on higher values ​​of sound insulation indices of enclosing structures - 3-7 dB higher than standard values. This solution will provide better sound comfort compared to apartments in standard houses.

It should be noted that all types of floors usually used in construction practice cannot meet regulatory requirements for noise protection without additional sound insulation. This especially applies to protecting the rooms below from impact noise.

For additional protection of the rooms located below, under the ceiling, from impact and airborne noise, it is necessary to ensure that sound from the floor is not transmitted to the ceiling. To do this, place soundproofing gasket between the floor and the ceiling. This principle of sound insulation is used in the construction of a “floating floor”.

Unfortunately, floating floors are very rare in our apartments. For this reason, in order to protect from noisy neighbors above, it is necessary to install sound insulation on the ceiling of the apartment from below the ceiling.

In addition, if you are a fan of loud music and often have musical instruments playing in your apartment or powerful audio equipment, then To save the nerves of yours and your neighbors above, sound insulation on the ceiling is also necessary. Noise protection is most effective if placed closer to the sound source.

Soundproofing the ceiling in an apartment

It should be taken into account that sound insulation on the ceiling best reduces airborne noise. Sound insulation on the ceiling protects less effectively from impact noise from above. The sounds of impacts that reach the slab or floor beams easily transfer to the walls and are transmitted to the room below.

Soundproofing the ceiling most often has to be done in apartments when it is not possible to insulate the ceiling from above.

Suspended ceiling - effective sound insulation of the floor from below

Soundproofing a floor using a suspended ceiling is especially effective when transmitting sound from bottom to top

Placing a special film (membrane) between the sheets of cladding significantly increases the noise-proof properties of the ceiling. Viscoelastic membrane mm kg/m2

kg/m2 with a thickness of 2.5 mm. In the Russian Federation, one of the companies sells material under the brand name Shumoblok TM. The material is sold in rolls 120 wide cm and length 5 m.

On the construction market you can find another soundproofing elastic membrane of the Tecsound brand. The Texaund 70 roll has dimensions (5 m x 1.22 m x 3.7 mm) and area 6.1 m 2.

Universal soundproofing mounts Vibrofix Protector for suspended ceiling frame profiles.

For attaching a suspended ceiling frame to the ceiling It is recommended to use special soundproofing mounts— pendants. A distinctive feature of such suspensions is the presence of an elastic element in their design.

The number of suspensions is calculated so that each suspension carries a certain load, at which the resonant frequency of the suspended ceiling system would be sufficiently low.

Sound-absorbing material in suspended ceilings is usually acoustic mineral wool mats or slabs. Soundproofing materials in the ceiling are laid tightly without gaps.

Sound insulation under suspended ceilings

Sound insulation under a suspended ceiling on a frame. Minimum thickness of structure 110 mm. Additional airborne noise insulation index: ΔRw = 14 – 16 dB.

The most effective sound insulation under a suspended ceiling is a device on the ceiling of a noise-proof suspended ceiling. The suspended ceiling structure contains all the elements (layers) necessary to reflect, dissipate and absorb sound energy over a wide range of frequencies.

For noise protection of ceilings under a suspended ceiling, there are no special requirements for leveling and finishing the surface. For this reason, some changes can be made to the design of the suspended ceiling.

For example, for cladding the ceiling, both for the outer and inner layers, gypsum fiber sheets are used. This material is denser than gypsum plasterboard, which improves sound insulation.

If it is not planned to lay a viscoelastic membrane between the sheathing sheets, then the sheathing is done in one layer with sheets of increased thickness. True, such a solution will worsen the sound insulation.

For cladding along the frame, you can also use acoustic panels made of Fonstar corrugated cardboard (PhoneStar) in one layer.

Noise-proof suspended ceiling of minimum height

In order not to greatly reduce the height of the room, they often try to make the thickness of the noise protection under the suspended ceiling in the apartment smaller.

For sound insulation under a suspended ceiling, it is advantageous to install a suspended ceiling with a minimum thickness of 55 mm.

An elastic substrate is laid on the ceiling over the entire area, for example, an acoustic sheet or soundproofing mats with a thickness of 10-20 mm. The substrate is fixed to the ceiling using mushroom dowels 70 long mm(2-3 mushrooms per 1 m2). The panels are overlapped by 4-5 cm. The joints of the panels are sealed with mounting tape with reinforcement.

Metal frame profiles PP 60/27 mm. fixed without vibration suspensions, directly to the ceiling through the substrate. To fasten profiles, special acoustic dowels - nails - are used. The absence of vibration suspensions, of course, reduces the noise-proof properties of the coating.

At the points where the frame is attached to the ceiling, the substrate is compressed and acts as a damper, reducing the transmission of vibration. Over the rest of the ceiling area, the material works to absorb sound waves due to its fibrous structure.

The gaps between the profiles can be additionally filled with sound-absorbing material - thin acoustic mineral wool slabs or mats.

The ceiling system must be vibration-isolated from the walls. It is necessary to lay a damping tape in two layers under the guide profiles.

Soundproof ceiling on a self-supporting frame

The self-supporting frame made of metal profiles has no connections with the ceiling. The frame is secured to the walls through an elastic damping gasket.

For soundproofing small rooms up to 3 m.(span) it can be advantageous to make a self-supporting frame from metal profiles. Such the frame has no connection with the ceiling, which has a positive effect on the noise-proof properties of the ceiling.

Holes with a diameter of 10-14 are drilled in the PN guide profiles mm., into which elastic vibration-decoupling mounting elements are inserted.

PN guide profiles are installed on the opposite long walls of the room, under the ceiling. A damper tape is laid between the profile and the wall over the entire height of the ceiling.

The profile is secured to the wall with dowels through elastic elements inserted into the profile. On sale you can find PN profiles with vibration mounting units already installed at the factory.

Elastic vibration decoupling mounting fasteners for guide profiles

Otherwise, vibration mounts for profiles are purchased and inserted into the profile yourself.

PS rack profiles are fixed into the guide profiles in increments of 0.6 m. When flying more than 2 m. rack profiles must be double. Acoustic slabs or mats are fixed to the ceiling or laid on top of the frame. You can additionally lay sound insulation slabs between the profiles.

Frameless sound insulation for suspended ceilings

If the ceiling does not have sharp differences in height (steps more than 10 mm high), then it is convenient to use frameless structures for sound insulation.

Frameless sound insulation with ZIPS panels

Noise and sound insulation under a suspended ceiling. The top layer is ZIPS panels; bottom layer - sheets of gypsum fiber board or gypsum board

Frameless sound insulation system with soundproofing panels ZIPS-Vector for additional sound insulation of ceilings under a suspended ceiling. Total thickness of sound insulation layer 55 mm. Additional airborne noise insulation index: ΔRw = 11 – 13 dB.(read more for more details).

The panels are fixed to the ceiling only through the existing fastening points. They are separated from all walls by two layers of elastic tape. Sheets of plasterboard or gypsum fiber boards are secured to the panels with self-tapping screws.

Frameless sound insulation with FonStar panels

The acoustic panel PhoneStar (similar products are also produced and sold under other trade names: Ticho; SoundGuard, etc.) has excellent soundproofing abilities. Read more about the materials below.

If there are no large and sharp differences (steps) on the ceiling, then FonStar panels can be attached under the suspended ceiling without lathing, directly to the ceiling. The panels are fixed to the ceiling using plastic acoustic dowels and nails.

In all cases, plasterboard sheets are attached to the acoustic panel with self-tapping screws 20 mm long.

Soundproofing of suspended ceiling Economy

The installation of suspended plus suspended ceilings under the ceiling is quite an expensive undertaking. In an economical option, only a layer of soft and light acoustic mineral wool slabs is often placed on the ceiling under a suspended ceiling.

Acoustic mineral wool slabs with a thickness of 3 - 5 can be used as a sound-absorbing layer. cm. The ceiling under the suspended ceiling is covered with sound insulation over the entire area. The materials are fastened to the ceiling using plastic dowels. The noise reduction level is up to 6 dB (2 times), this is noticeably less than the option with a suspended ceiling.

Do-it-yourself sound and noise insulation of the ceiling in an apartment

Ceiling metal profile PP 60/27. Gypsum fiber sheet GVL thickness 10 mm. GKL plasterboard thickness 12.5 mm. Sound insulation slabs made of stone wool with a density of at least 60-80 kg/m 3., thickness 30-50 mm. Vibration suspensions based on Sylomer material. Sealing self-adhesive tape made of chemically cross-linked polyethylene foam, 3 mm thick. in two layers.

The suspended ceiling is hemmed using lathing attached to the slab or floor beams using elastic hangers.

To reduce the resonant frequency of the oscillatory system, the elastic suspension is the casing, it is recommended to increase the mass of the casing sheets. The use of a multilayer structure, in which each layer has its own structure and elasticity of the material, different densities and other differences, allows you to effectively reflect, absorb and dissipate sound energy.

Ready-made parts for suspended ceilings on elastic hangers can be found on the construction market.

Installation procedure for ceiling soundproofing

Before starting work on soundproofing the ceiling, carefully inspect the ceiling for cracks. The cracks must be expanded and sealed with cement-sand mortar.

Look at where the floor slabs meet the walls. If cracks are found, they must also be eliminated.

The design of a suspended ceiling using elastic elements based on the material Sylomer (Austria) has proven itself very well in practice.

Install vibration suspensions on the ceiling to secure the metal profile of the suspended ceiling. The number of vibration suspensions is calculated based on the total weight of the structure. Usually we accept a suspension pitch of 600x800 mm. The outermost vibrating suspensions in the rows are located no closer than 150 mm from the wall. Recommended fastener – universal self-tapping screw 6x70 mm and plastic dowel 8x60 mm or metal wedge anchor 6x60 mm.

Attach guide profiles PN 27/28 to the walls mm. Under the guide profiles you need to put a damping tape in two layers. For fastening use dowels 6x40 mm. based on 2 PC. per 1 linear meter of profile.

Secure soundproofing boards over the entire ceiling area. For fastening, the slabs are pinned onto vibration suspensions installed on the ceiling. Additionally, plastic mushroom dowels with a length of 70-100 are used. mm. You can also use polyurethane foam adhesive. Installation of slabs before installation of the ceiling profile, allows you to cover the entire surface of the ceiling with sound insulation without any gaps.

Install the suspended ceiling frame using vibration suspensions using elements of the PP 60/27 ceiling profile mm. Bearing and transverse profiles are mounted on one level in a standard way. The position of the profiles on the ceiling should be such that All joints of the sheathing slabs must fall on the profile.

After installing the frame structure from the guide profile PN 27/28 mm. the temporary dowel-nails securing it to the wall are removed. The ceiling frame should remain hanging only on vibration suspensions.

The first layer of sheathing made of gypsum fiber sheets GVL with a thickness of 10 is installed on the frame. mm. The sheets are attached to the profile using 3.5x20 self-tapping screws mm with a pitch between screws of 20 cm. The sheets on the ceiling are placed offset (in a staggered manner) so that the joints do not merge into one line along the entire ceiling. Along the edges of the ceiling, gypsum fiber sheets rest against a damping tape. The joints of the sheets are sealed with vibration-resistant silicone sealant. Instead of gypsum plasterboard sheets, plasterboard gypsum boards can be used for the first layer of cladding, which will lead to some deterioration in sound insulation parameters.

Then a second layer of sheathing made of gypsum board sheets with a thickness of 12.5 is attached to the frame. mm. The sheets are laid offset relative to the first layer, so that the joints of the sheets in the first and second layers do not coincide. To attach the second layer, use 3.5x40 self-tapping screws mm.

The joints between the gypsum board sheets are sealed as usual, using putty and sizing with tape.

After installing the suspended ceiling sheathing, it is necessary to cut off the protruding parts of the damping tape. Seams along the perimeter of the sheathing, in places where they adjoin the walls, if necessary, are sealed with silicone vibroacoustic sealant. The use of polyurethane foam is unacceptable!

Materials for sound and noise insulation of ceilings

Soundproofing slabs made of mineral wool

In mineral wool slabs, fibrous particles are held together by an adhesive.

Special slabs made of acoustic mineral wool are used as a sound-absorbing filling for a suspended ceiling or under a suspended ceiling. Acoustic mineral wool is distinguished by a special arrangement of fibers. Due to this, it has low dynamic stiffness and better noise absorption compared to ordinary wool. At the same time, this material remains a good heat insulator.

The ability to absorb sound is highly dependent on the density of the slab material ( kg/m 3). The higher the density of mineral wool slabs, the better the sound is muffled.

Since slabs made of acoustic mineral wool are used indoors in residential premises, I advise you to pay attention to the indicators of the release of harmful substances from them. Often, sellers will tell you about the environmental friendliness of the material, about the absence of phenol emissions, phenol-formaldehyde, but are silent about other emissions.

Various manufacturers market acoustic mineral wool products under their own trade names. For example, acoustic mineral wool AcoustCWool Concept (54 kg/m 3±10%, NG).

Most often on sale you can find noise protection boards measuring 1-1.2x0.6 m. and thickness 20 - 50 mm., with a bulk density of 45-110 kg/m 3.

Soundproofing mats

A soundproofing mat (acoustic fabric) is similar to a quilt. In it, compressed fibrous material is enclosed in a shell of fabric or film. Noise-proof mats can have a length of up to 10 m., width 1-2 m. and thickness 10-20 mm.

The material can be cut, bent, folded, squeezed. When squeezed, it has elasticity.

For example, the SoundGuard COVER heat and sound insulating mat contains fiberglass canvas, mechanically compressed and sealed in a protective spunbond shell. Serves as a vibration-damping pad under the floor screed and as a noise-absorbing layer in wall and ceiling structures. The dimensions of the SoundGuard CARPET heat and sound insulating mat are 1500x5000x15 mm. Bulk density – 136 kg/m3. Surface density – 1.46 kg/m2.

Sound insulation of ceiling sandwich panels

Recently, sandwich panels have begun to gain great popularity in the market of soundproofing materials. They are a multilayer slab made of materials with different properties - different densities and structures in each layer. Alternating layers with different densities and structures helps dissipate sound energy.

The advantages of using panels include the absence of the need to install a metal frame - they are attached directly to the ceiling. In addition, it is often possible to reduce the overall thickness of the sound insulation layer, which reduces the loss of room height. The disadvantage is that To install sandwich panels, the ceiling surface must be leveled with plaster.

The panels are mounted using vibration-isolating fasteners through special units manufactured by the manufacturer. The thickness of such panels can be from 8 to 150 mm, and is selected based on the requirements for ceiling sound insulation. The panels can be joined to each other using a tongue-and-groove connection.

A finishing layer of plasterboard with a thickness of 12.5 is attached directly to the sandwich panel. mm. If a layer of viscoelastic membrane is placed between the panels and the drywall, the level of sound protection will increase noticeably. The increase in the sound insulation index of a wall with sandwich panels can be from 9 to 20 dB.

Sandwich panel made of corrugated cardboard

Soundproofing the ceiling using acoustic panels 15 thick mm., total thickness including the finishing layer of drywall 32 mm., increases the airborne noise index by 9-10 dB.

For example, the Ticho acoustic panel (similar products are also produced and sold under other trade names: Fonstar (PhoneStar); SoundGuard, Sonoplat (Sonoplat), etc.) is made of durable cellulose multilayer corrugated cardboard.

Inside the panel there are several chambers filled with sand, feldspar-quartz composition of different fractions using vibration compaction.

The panel has excellent soundproofing properties. This result is achieved by increasing the specific gravity of the panel, increasing the number of alternations of dissimilar layers and an integrated, elastic, vibration-damping layer, as well as free, unconnected filler particles.

The panels are intended for use in dry and heated rooms. Panel dimensions 1200 x 800 mm., thickness 8-17 mm. and weight 10.5 - 21 kg. The panels can be easily sawed with a hand saw or power tool. When sawing, slight spillage of filler may occur. The edge of the cut is covered with construction tape.

Acoustic panels made of corrugated cardboard can have a profiled edge for convenient and high-quality installation of soundproofing coating

The panels are attached so that their smooth side with the label remains on the outside. The panels are fixed directly to the ceiling using plastic acoustic dowels and nails. When marking holes, the distance from the edge of the panel is 50 mm, step 200-250 mm. The dowel head must be recessed by 2 mm deep into the panel and coat the top with soundproofing sealant. This is done to avoid contact between the dowel and the gypsum board sheet, which is sewn over the panels.

The panels are attached to the ceiling profile using GM 3.5x30 self-tapping screws. One panel requires at least 21 screws. The rows of panels are arranged staggered (with a slight offset of the joints so that they do not coincide with each other).

Acoustic sealant is applied to the panel joints. The sealant is also applied to the fastening points, and the holes in the panels for the passage of pipes and other communications are sealed. After installation, the joints of the panels are taped with adhesive tape.

Drywall sheets are secured to the panels with self-tapping screws in increments of 400 mm. To avoid creating sound bridges, the drywall is fastened with self-tapping screws 20 mm long. mm. to the panels, and not to the sheathing profiles.

The edge of the gypsum board, which runs along the perimeter of the ceiling, should not come into contact with the walls, as this can become a sound-conducting bridge. There is a gap of 3-5 mm, which is also treated with soundproofing sealant.

Finishing work (puttying, painting, whitewashing, priming, etc.) directly on soundproofing panels, without covering with gypsum board sheets, leads to deformation of the surface of soundproofing panels and the impossibility of their operation.

Sandwich panel made of ZIPS mineral wool

And here is another example of a soundproofing sandwich panel. A layer of acoustic mineral wool is factory-installed on a gypsum fiber board and vibration-isolating sockets are made for attaching the panel to the wall. Watch a video about such a wall soundproofing system sandwich panels ZIPS:

Index of additional airborne noise insulation of the ZIPS-III-Ultra panel system: ΔRw = 11 – 13 dB. Sandwich panel thickness: 42.5 mm.
Total thickness of the system with the finishing layer of gypsum board: 55 mm.

Depending on the thickness of the mineral wool layer, ZIPS panels can have a total thickness of 40 - 120 mm.

In addition to the panels, do not forget to purchase a mounting kit for them.

Sandwich panels made of polystyrene foam and polystyrene foam

On the construction market you can find sandwich panels that use foamed polymers as a sound-absorbing layer: polystyrene foam, extruded polystyrene foam, polyethylene foam, polyurethane foam. The soundproofing properties of such panels, especially for protection against airborne noise, are significantly lower than those described above. Sellers often mislead buyers by claiming the opposite.

Viscoelastic soundproofing membranes

Viscoelastic membrane is a synthetic soundproofing material based on a polymer base. The most important difference between the material is its elasticity combined with high density. With a thickness of 1.8–5.3 mm the surface density of the membranes is 3.5–10 kg/m2. The combination of materials with different properties in the skin creates conditions for multiple reflection, dispersion and absorption of sound wave energy in each layer.

Soundproofing systems using plasterboard sheets and viscoelastic membranes are used not only for soundproofing ceilings, but also for walls and acoustic screens. The membrane is glued directly to the surface of the plasterboard sheets from the inside, from the side of the supporting frame. The most effective use of the membrane is as a clamped layer between two sheets of drywall.

For example, a soundproofing elastic membrane made of Mass Loaded Vinyl, which contains the mineral Baryte or Argonite. Acousticblok, a well-known brand of material abroad, has a surface density of 5 kg/m2 with a thickness of 2.5 mm.

In the Russian Federation, one of the companies sells material under the brand name Shumoblok TM. The material is sold in rolls 120 wide cm and length 5 m.

You can find another one on the construction market soundproofing elastic membrane of the Tecsound brand. The Texaund 70 roll has dimensions (5 m x 1.22 m x 3.7 mm) and area 6.1 m 2. Sound insulation Texound is an ultra-thin elastic heavy membrane, the basis of which is the natural mineral aragonite, which has a high specific gravity, and binding polymers. This composition provides the Texaund 70 membrane with elasticity with a record surface density (6.9 kg/m²) with a thickness of less than 4 mm.

Gluing gypsum board sheets with Texound70 membrane. The sheets are placed on a horizontal surface. Make sure that they do not get dirty or small debris. Glue is applied evenly onto the gypsum board sheet using a roller. Baurger glue consumption 0.2 l/sq.m. It is possible to use a self-adhesive membrane Tecsound 70SY. The Texaund 70 membrane is evenly laid out on top of the drywall. The edges of the membrane should protrude beyond the edge of the gypsum board by 1 cm from each side. The smooth surface of the membrane is glued to the gypsum board, the side glued with the fabric remains clean, it will be adjacent to the first layer of plasterboard on the suspended ceiling. The edges of the Texound70 membrane protruding beyond the edge of the gypsum board sheet are trimmed as smoothly as possible. GKL sheets glued with a membrane are mounted on the first layer of GKL with 3.5x45 self-tapping screws mm.

Noise-Insulating Canvas (PSHI)– this is a heavy membrane, of small thickness (2-4 mm), which is a composite of high-quality rubbers. This material has good elasticity and can be used in various soundproofing structures. High sound insulation properties with small thickness are achieved due to mass. Material weight is 7.6 kg/m2, with a thickness of 4 mm. Membranes are made with or without adhesive.
