How to make a sound insulation in an apartment

Sound insulation problems are more puzzled by residents of apartment buildings. One of the neighbors plays a musical instrument, someone has repairs in full swing, from the ceiling there is a clatter of small legs and such rubbish all day, and sometimes you really want to relax in complete silence. But it happens on the contrary, you want a noisy party, but there is no desire to spoil relations with neighbors.

As a rule, new houses do not differ in good sound insulation: voids in the walls, openings of sockets and switches, inputs of heating and water pipes, as well as the structural elements themselves perfectly convey any sounds. Therefore, sound insulation in the apartment is the work of the inhabitants themselves.

Sound insulation of walls and partitions

The main conductor of extraneous noise in any room are walls and partitions. The walls bordering on the street do not need to be isolated. From the noise that penetrates outside, you can get rid of just by installing double -glazed windows on the windows. If this is not possible, then you can replace the glass with thicker ones or provide them with a thicker connection to the frame. To do this, it is enough to walk around the perimeter of glass with a silicone sealant.

But the internal walls and partitions do not differ in a special thickness and remarkably convey sound vibrations of any frequency from the next room. The easiest way to reduce the level of noise penetration into the room through the walls is the sound insulation of sockets, mounting boxes and joints, which we will talk about below.

For sound insulation of very thin walls and partitions, it is better to use a multilayer structure, which differs in alternating layers of various densities. This method differs in high cost and gives a good result only when using high -quality materials. The fiberglass, basalt, spatling or silica fiber, as well as already ready sandwich panels are most effective for this purpose. Soft layers are faced with drywall panels.

Having decided on multilayer sound insulation, keep in mind that the area of \u200b\u200bthe room will be significantly reduced. Each faced wall reduces the linear dimensions of the room by more than 15 cm.

Technology of multilayer sound insulation of the walls:

1. A wooden or metal frame is being built to fix the soft insulating material. Metal, of course, will be stronger, but it will reduce the soundproofing properties, so it is preferable to use a tree. During the construction of the frame for all its areas, in contact with the wall, it is necessary to put rubber or polyurethane gaskets.
2. The empty space formed by the frame is filled with soundproofing material.
3. The resulting design is faced with drywall sheets or any other selected panels. After that, the joints are glued with a painting ribbon and plunged. Next, another layer of the hard insulator is applied, but at the same time the seams are overlapped to the previous ones.
4. The second layer is putty and now it can be safely painted or poured with wallpaper.

For example, we present to your attention a video that shows the process of soundproofing the room using the ISOVER material.

Sound insulation of sockets and installation boxes

During construction for outlets and mounting boxes, through holes are arranged, allowing to simultaneously install electrical equipment and accessories at once for two rooms. Therefore, they serve as excellent wires of noise from the neighboring room.

Before proceeding with isolation, it is necessary to de -energize them. After that, we completely remove the entire electrician from the hole, and inward we place a cork cut from any sound -absorbing material, for example, basalt fiber, and carefully cement it.

Installation boxes are isolated in the same way, only they differ in the presence of a plastic plug, which must be pulled out. By the way, if you do not know, you can find the location of these boxes by tapping the wall.

Sound insulation of joints

If the house is panel, then as a result of natural precipitation of the building, deformations of structural elements and poor -quality work of builders, in places of joints of neighboring walls, as well as walls and ceiling or floor, cracks are formed, which also miss the sound very well. It is not difficult to get rid of them. It is necessary to expand all cracks with a screwdriver or any other sharp tool to 30-40 mm, thoroughly clean their cavity, completely primed it and cover the putty with a layer of putty. After complete drying, the joints should be covered with sealant, better acrylic.

If the floor is already on the floor, then it can not be disassembled. For good isolation, it is enough to fill in the gap between the wall and the flooring with silicone and cover it with a baseboard. As a rule, this helps to significantly reduce the level of oscillations transmitted through the floor.

Sound insulation of the entrance doors

A large number of sounds penetrate the apartment due to the front door. Conversations of the neighbors, clapping doors, the sounds of the elevator, steps on the stairs - you can also get rid of them. The main requirement for the entrance doors, which provides a high level of sound permeability, is the absence of cracks. Therefore, it is enough to attach rubber seals in the places of contact of the door leaf with a jamb and equip the door frame with at least a small threshold. If there are cracks between the box and the doorway, then they must be filled with cement mortar.

A good soundproofing effect gives the use of two doors, and the second can be a thin decorative partition. The main thing here is a small vestibule, which extinguishes oscillations.

Sound insulation of the floor

You need to take care of the sound insulation of the floor before laying the flooring. Otherwise, it will need to be disassembled. To isolate the floor from the penetration of extraneous noise and protect neighbors living from below, from sounds penetrating from your apartment, you need to place special insulation material under the flooring or, even better, under the floor screed. Such materials for soundproofing are a thin layer of fiberglass, polymer or other substance, which has high plasticity and elasticity. It is necessary to lay such isolation so that its edges go to the walls, in this case, sound vibrations will not spread beyond the surface of the floor.

Sound insulation of the ceiling

The best way to insulate the room from the penetration of extraneous noise from the ceiling is the installation of suspended or suspended ceilings. It is better to entrust such work to real professionals. It independently is almost impossible to pull the canvas without wrinkles and distortions. Especially if you have never done this work before.

If funds do not allow you to invite specialists, then you can try to isolate the ceiling with a multilayer structure. The technology of this work is not very complicated and accessible even to a novice repairman:

1. The ceiling is thoroughly cleaned of the entire coating.
2. A special acoustic material is glued over the entire surface, often felt. To prevent a lag, it must be attached with dowels-gribs.
3. At a distance of 60 cm from each other, suspensions of profiles are attached, and on them a profile for drywall.
4. Sound -insulating material slabs are laid on the ledges, while a small air layer should remain between them and the acoustic gasket. Usually enough 50-100 mm.
5. The whole structure is faced with drywall.

Having decided to independently isolate the apartment from the penetration of noise, keep in mind that for a good result it is important to use high -quality materials with high soundproofing properties. All costs on them are quickly compensated by the calmness of your family and good relationships with neighbors.
