Noise insulation of walls in the apartment Modern materials. Sound insulation of the wall in the apartment. Soundproofing materials for walls and ceilings

The rhythm of the modern city, high concentration of the population, technical progress is accompanied by an abundance of loud sounds. The best sound insulation of the walls in the apartment provides a comfortable rest, restoration after a hard day's day. Architects and builders at the stage of erecting the building should ideally solve the issues of sound insulation. Due to the cost of construction, this is often not given due attention to this. On the other hand, it is possible to improve the comfort of the internal living space with the help of special soundproofing materials, which are highly effective against noise, resistance to moisture, fire. Due to their great variety, it is easy to get confused, since each species is intended for specific conditions and types of noise. The safety of use in residential premises, installation features also matter. Having understood all the subtleties, everyone will be able to make the right choice than to make the soundproofing of walls in a particular apartment.

Varieties of noise

Modern apartment buildings are filled with a huge variety of sounds. The soundproofing of walls in the apartment will provide modern materials. They should be selected, focusing on the nature of sounds.

All the noise inside an apartment building can be divided into three large groups:

• the air variety is characterized by the spread of sound waves by air without interaction with enclosing structures. This type includes loud music, children's crying, working TV, barking dogs;
• shock noise occurs due to mechanical interaction with ceilings, walls. For example, this is the sound of steps, the noise from the movement of furniture;
• the structural type of noise is distinguished by the direct intensive contact of the sound source and the structural elements of the building. In this case, the beats of the hammer, the sounds of a working perforator spread in large areas.

In residential buildings, office premises, an air variety of noise prevails, and production buildings are often filled with structural and shock sounds. For comfortable home conditions, it is necessary to provide protection against all types of noise influences, since psychological, physical fatigue leads to depletion of the human body and serious health problems.

Determining the front of sound insulation work

Which room is isolated from noise in the first place, it is necessary to solve it with a balanced. At the same time, it is important to take into account the need to protect against external noise or the desire to isolate the internal space, in which loud music often plays. In the first case, it is better to protect the bedroom, living room from external noise exposure, and in the second room with a home cinema or karaoke, a bathroom, a toilet.

In addition, it should be determined which structural fencing of the building should be isolated from noise in the first place: walls, floor or ceiling.

It should be borne in mind that the effectiveness of sound insulation depends on the thickness of the insulation materials.

At the stage of erecting the building, work is carried out to limit noise penetrating from the outside. To do this, in accordance with the building codes, noisy or quiet rooms are combined into separate zones. If the external sources of sound bring concern, then you should take care of additional protection against noise.

Types and functions of soundproofing premises

Materials for soundproofing walls in the apartment prevent the penetration of external sounds, and also protect neighbors from the noise that is produced indoors.

With their help, the following tasks are achieved:

• sound waves are absorbed and dissipated;
• the occurrence of the vibrations of the wave obstacle is not allowed.

The main appointment of soundproofing is a reflection of the sound, maximum preventing its penetration into the room. Dense surfaces made of concrete, brick, gypsum cardboard are effectively cope with this. Absorb the noise of the surface that have a cellular, fibrous structure. All materials are characterized by a noise absorption coefficient, the maximum value of which corresponds to one.

They are soft, hard or half -timed. It is best for the walls of private houses to use the sound insulation of a small weight, which is characterized by a high degree of absorption of sound waves.

To choose the right insulation material, it is necessary to take into account the nature of the sound itself.

Effective protection against sounds that spread through the air

The level of protection against air noise, characterizing different materials, is determined by the RW index. If it corresponds to at least 50 dB, then this is enough so as not to hear the sounds of voices, music behind the wall.

The most common method of basic insulation is the arrangement of walls from foam blocks, reinforced concrete, which, in a complex with a binder, create a monolith with increased tightness. In the presence of rigid compounds, even the use of various combinations is allowed.

In addition, effective sound insulation is achieved using many layers of various density and rigidity. The sound -absorbing function is perfectly performed by mineral wool, silica fibers that fill the interior of the wall of brick, aerated concrete and drywall. It is important that the thickness of the inner layer is at least 50 mm.

The sound insulation of the ceiling will also help effectively protect the apartment from noise.

Materials mitigating the effect of structural noise

To protect the joints of the supporting structures, special gaskets are used. To perform work efficiently, the following materials are perfect:

• silica fiber;
• fiberglass;
• elastomers;
• a sealant with vibro -acoustic properties.

To achieve a good result, it is important not only to choose high -quality materials, but also to design them in the right design. The comfortable atmosphere will be helped by professionals who specialize in acoustics.

Izolation protection against impact -like noise

Special porous materials should repel sound waves of this type, significantly weakening them. The level and efficiency of shock noise is determined by the LNW index. One of the options for protection against such sounds is a multi -layer floating floor. It is formed from porous protective material, which is poured with a concrete screed 6 cm thick. A substrate, laminate, parquet or other finish coating are laid on top.

Most often, these materials are used for these purposes:

• bitumen-proof coatings;
• composite materials;
• pressed cork baby;
• foam polystyrene.

Varieties of soundproofing constructions

Modern interior decoration uses frame and frameless technologies for the installation of facing systems to protect against noise of various origin. They are installed on dense surfaces of powerful load -bearing walls.

On the other hand, special thin materials are used for interior partitions with a thickness of not more than 100 mm.

Features of subtle sound insulation

Modern finishing technologies can significantly save the living space of the premises when achieving the desired effect. Thin soundproofing walls in the apartment was widely used when creating various interiors.

This is due to the following positive properties:

• light and relatively quick installation;
• significant savings of space;
• wide range of decorative materials;
• environmental safety.

All work on installing subtle sound insulation can do a person who does not have construction skills and skills.

Frame cladding

Such systems contain more elements, but they are characterized by greater versatility. The technology of their installation completely repeats the installation of gypsum cardboard, but the internally space between the surfaces is filled with insulating material. The established design simultaneously solves the problems of insulation, sound insulation and leveling of the walls.

Effective soundproofing facing system consists of the following elements:

• metal profiles 0.55 mm thick;
• acoustic insulating triplex with a thickness of 17 mm;
• facing sheet of gypsum cardboard 12.5 mm;
• sound -absorbing non -combustible slabs 50 mm thick;
• fasteners from special elastomer;
• 4 mm vibration -insulating gasket for installation in places of adjustment of the structural elements to the walls, ceiling;
• vibro -acoustic sealant for joints of design with surfaces.

These frame panels have a thickness of 90, 110, 140 mm. Depending on these indicators, the soundproofing index of air noise (RW) is different.

Protective facing systems that are mounted without a frame

A vivid representative of these cladding is a soundproof panel of a ZIPS. This design includes eight vibro -insulating points of fasteners, a soundproof system. The finish sheet of this multi -layer structure is a plasterboard of 12.5 mm thick.

This design is attached directly to the wall: first the panel itself, and it is already a drywall to it. The thickness of the ZIPS varies from 53 to 133 mm. Depending on these indicators, the level of air sound insulation from 50 dB, which is initially supported by the supporting wall, increases by 9-18 dB.

There are the following varieties of the system (table):

This panel over 17 years of use showed its effectiveness with the ease of materials and high speed installation.
