Noise isolation of apartment walls. How to Make Your Own Hands

The level of sound insulation of modern apartments, and in particular in new buildings, leaves much to be desired. To correct this situation at will is quite possible and independently. It will not be too expensive and will not take much time. In this article, we will consider the question of how the noise insulation of walls is carried out correctly.

Varieties of soundproof materials

The modern market offers the consumer a wide variety of soundproof materials. You can classify them into three main groups.

1. Tough. Absorption of sound by these materials is due to the fact that one of their constituents is a porous filler (pumice, expanded clay, cork, perlite, etc.).
2. Semi-rigid. They are made of materials based on polyurethane. This group includes foam plastic, expanded polystyrene, etc.
3. Soft. Manufacture of such sound insulation based on mineral wool or fiberglass. Soundproofing of apartment walls using this kind (along with semirigid) is performed most often.

How to choose the right material

There are only two types of noise - air and shock. In the first case - it can be music, loud voices, distributed behind the wall, etc. Shock noises occur, for example, when a drill or perforator is operating. Usually, sound insulation of walls implies protection from air noise, and floor and ceiling - from shock. Noise insulation of walls with their own hands can be performed using:

• Mineral wool. This is a very inexpensive material with excellent performance. Great for protection against air noise. Its only drawback is a rather large thickness. Therefore, it is expedient to use it in large areas.
• Cork soundproof material. It perfectly protects both from air, and from shock noises. With success can be used to insulate the walls of both a large and a small apartment.
• Soundproof panels ZIPS. Noise insulation of walls using this material is most effective. The main disadvantage of such panels is their rather significant weight, hence, the complexity of the installation.

Preparatory work

Before proceeding with the installation of sound insulation material, the walls must be carefully prepared. All cracks and possible holes must be found and sealed. Also it is necessary to make soundproofing of jacks of sockets. Of course, before starting this work, electricity in the apartment must be disconnected (in the shield). The rosettes are dismantled and removed from the nests. The holes can be insulated with foam rubber, foam or fiberglass. At the final stage, all the crevices are covered with gypsum. Sealing is also necessary for the exit of all pipes in the apartment (water, heating, gas). Further, the walls are thoroughly cleaned of dust and dirt.

Sound insulation using mineral wool

Mineral wool - a material for noise insulation of walls, of which we spoke above. Its installation is as follows:

• The metal profile is pasted with a special polystyrene tape absorbing noise;
• Guide rails are mounted;
• Rack profiles are installed;
• Between them are mounted pre-cut mineral wool plates;
• Installation of an additional profile 2-3 cm thick (it is necessary in order for a small ventilation gap to remain between the plates of the noise isolator and the gypsum board);
• Gypsum boards are installed.

Sound insulation of walls with cork panels

In this case, a special quick-setting adhesive is used. The wall is carefully etched, after which the element is pressed tightly against it. Installation is carried out with a shift to half-plates. Cork laying should be done as tightly as possible. The presence of any gaps between the elements is not allowed. Cork panels are aesthetic in themselves. Therefore, it is not absolutely necessary to perform additional finishing in this case. The exception is the walls of the bathrooms. In this room, the slab should be covered with a special lacquer-sealant.

How to perform soundproofing with panels ЗИПС

Further on, let us examine in detail the question of how to make noise insulation of walls using sandwich panels. Preliminary on the perimeter of the wall on the floor, adjacent walls and ceiling are glued special tape-spacers, the width of which is equal to the thickness of the sandwich panels. Instead of the adhesive, a special acoustic sealant is used.

Plates are mounted on the wall using special dowels. The installation should be performed from left to right and from bottom to top. Panels of the first row are cut along the short and long side, and all subsequent ones are only long. The element is attached to the wall and through the vibration isolation units already existing in it, holes are drilled with a depth of 6 cm. Then dowels are inserted and clogged in them. Also all the subsequent plates are mounted (the run-off of joints is not less than 25 cm). Pazogrebnevye joints of panels are additionally fastened by screws (a step - 15 sm). At the final stage, the joints of the panels are treated with a grinding handle. After that, all the seams are filled with sealant.

Wallpaper gluing

The noise insulation of the walls will be even more effective if you use vinyl foamed wallpaper as the final finishing. Wall gluing should be started from the window. Using the level, a vertical line is preliminarily drawn on the wall. It will serve as a guide for gluing the first band.

Cloths are smoothed over the surface of the wall by a soft roller with medium-length fur. Air bubbles are removed with a special wallpaper brush. Get on the surface of the adhesive, remove the adhesive with a clean rag. Since foamed wallpaper - the material is not too strong, pasting should be done as carefully as possible.

As you can see, the noise insulation of walls by oneself is not a complicated process. With a little effort, you can make living in an apartment or house much more comfortable. The most important thing is to do everything without haste, lay all the elements as tightly as possible to each other and carefully seal all joints.
