In most cases, the presence of a low noise level is a pledge of a comfortable pastime in the residential room. But not always during the repair work this factor is given due attention. This is radically incorrect, especially when the device is interior partitions. In this article, we will also tell about how to make sound insulation of the plasterboard partition.

Methods of efficient sound insulation

It is possible to achieve a maximum result when conducting sound insulation of drywall partitions can only be compliance with the requirements that do not have a direct relationship to the design itself. In particular, in indispensable conditions for creating favorable conditions in the room are:

• installing a window equipped with a minimum double-chamber glass;
• wall finish with noise absorbing materials (plaster mixes, gyrors or pr.)

This will reduce the level of noise, which is coming from the street or from the next apartment.

As for the plasterboard partitions, reliable soundproofing it is created by alternating hard building materials with soft goods. The only way the drywall will not miss the noise and sound insulating materials become a barrier to neutralize the different sounds. Good sound insulation is obtained when the following conditions hold:

• it carried out the installation of two separate frames, which serve as the basis for gypsum boards;
• fixing all elements and fasteners produced using sound-absorbing pads;
• absolute tightness ensured partitions (there should be no cracks, holes or other strain).

In order to meet the design criteria of the latter, all the joints are subject to amortization spackling using grid. When installing electrical wiring and other communications, the joints are treated with silicone sealant.

Materials for filling the walls of plasterboard

Of particular importance for the creation of an ideal comfort in the room have soundproofing materials. They should have the technical characteristics:

• sound absorption coefficient of 0.8 or more;
• thickness of more than 10 cm;
• their proportion in the area created by the design must exceed 50%;
• different easy installation on the wall;
• have a minimum water absorption;
• have sufficient strength and maximum service life.

In most cases, sound insulating materials plasterboard sold in rolls or plates. they are classified by the degree of hardness:

• solid;
• semi-solid;
• soft.

Immediately should mention the acoustic drywall. His sheets composed of a plurality of holes. Due to the perforated surface area increases muffler and noise reduction occurs upon reflection of sound waves. The reverse side of gypsum board covered with non-woven fabric. Thanks to it significantly reduced the number of sound waves passing into the interior of the partition. For this reason, the scope of the use of acoustic material is not limited to the lining of ceilings and walls. It can be used inside the walls. The most popular products is an acoustic plasterboard Knauf Gyptone and acoustics. Materials that can be used for soundproofing drywall partitions inside include:

• acoustic diaphragm;
• fiberglass plate;
• kamennovatnye panel;
• polystyrene;
• polyurethane and polyester plate;
• mineral wool products;
• sprayed coatings.

Membranes that reduce the noise level are a subtle polymer web. It is covered with a layer of villi from felt. The membrane thickness ranges in the range of 3-12 mm. This size allows you to use this sound insulation material in the most subtle partitions. The principle of action of membranes is similar to a sound barrier that prevents the propagation of sound waves. Felt patches on the surface of the material absorb part of the sound. TECSOUND sound insulation membranes use the greatest demand. Pretty in demand and plates of Knauf Insulation made from fiberglass. Although the plates have a high cost, they are one of the leaders in the parameters of the isolation of sound waves. Moreover, this material is obsessed:

• wet;
• rotten;
• burning.

Rockwool sound-absorbing mats are made of stone wool. Due to the homogeneous structure of the panels, there is excellent dispersion of air. Chained plates are non-combustible and environmentally friendly material. A good option for sound insulation of plasterboard partitions will be the use of polystyrene foam. He also does not miss moisture. The only nuance is the correct sealing of the joints between the plates. But this gap is already resolved by many manufacturers. There are sheets of polystyrene foam, which have a stepped docking edges. As a sound-absorbing material for plasterboard structures have proven themselves polyurethane foam and polyester plates. But they have a significant "minus" - some of the components of these materials burn. And this is unacceptable in the regeneration of the partitions in a residential building. Mineral wool is often used for insulation constructions. But her you can use for sound insulation purposes. On the one hand, mineralnovatnye materials have a low weight, non-susceptibility to burning and decay, long life. On the other hand, the mineral wool "breathes", which may lead to the accumulation of moisture. For this reason, for the effective noise reduction is necessary to additionally use a polyethylene film.

Among the latest developments in the field of sound insulation should be allocated sprayed coatings. This material consists of cellulose fibers, which are impregnated with a special adhesive. Application of the material by means of the spraying process. This makes it possible to create an acoustic desired layer thickness. To create a reliable soundproofing drywall is fine Sprayable mixture Sonaspray.

Mounting work

At the initial stage, the surface markup occurs. It is recommended to use the laser level. With it, it is possible to most accurately projection the surface to place the erected partition. After conducting marking works, you can proceed to the framework of the framework. To do this, you can use wooden bars. But the best option is metal profiles. There is a mounting of a rack profile around the perimeter of the walls, gender and ceiling. As a result of these actions, a single vertical plane should be obtained. To reduce the indicator of the shock sound wave, use the elastic material of vibrastek. It is located between metal elements and supporting structures. If necessary, suspensions with polymer inserts are used. The fixation of the guide profiles is carried out with the help of self-"bugs" screwed into 40 cm increments. In places of contact of the guide and rack profiles, polymer gaskets are laid. To reduce the effects of vibration waves, all existing cracks are sealed with silicone sealant. Near door openings, the installation of wooden bars, which are attached with the help of self-tapping screws.

Frame ready. It is possible to fill it with sound insulation material, which is placed between the elements of the crate. The design will have maximum sound insulation properties subject to the following conditions:

• creating a septum of plasterboard sheets is made from two sides;
• plasterboard must have a thickness of 12.5 mm;
• the gasket of communications inside the partition is carried out using polyurethane covers (for pipes) and plastic housings (for wiring);
• the fastening of sound insulation mats occurs with the lack of space between them;
• the displacement of the seams between two parallel walls in the partition should be at the level of 20-30 cm;
• a noise absorbing membrane is used, placed on top of mats.

In the absence of membrane materials, a porous tape is mounted between plasterboard sheets and profiles. After final fixation of the casing material, the slots are seal between the floor and the bottom of the sheet. This uses silicone sealant. The final stage of working with plasterboard provides:

• shavi extender;
• their shlatovy;
• priming surface;
• finishing its finishing coating.

As a result of the use of drywall for the partition, you can "kill two hares at once." First, we will get perfectly smooth walls. Secondly, the design with increased sound insulation will enjoy the absolute silence in the room. Video on sound insulation of the plasterboard partition:
