In life, one of the sources of constant stress is various noise. Therefore, within the walls of your home, you really want to be in silence. To reduce noise, soundproofing of the floor, ceiling, walls is used. Next, let's figure out how to protect yourself from extraneous sounds.

General information

2 types of sounds reach people living in an apartment building through the interfloor ceiling - air and percussion. The first should be understood as noise propagating through the air. For example, TV sound or music. The shock one appears from the direct mechanical impact on the floor. It arises from heels, the running of children, is heard when rearranging furniture. From the ceiling, the noise spreads to the surface of the walls and is transmitted to the room below. In addition, the sound often interferes not only from above. In this case, properly arranged floor soundproofing in the apartment will relieve constant irritation and stress.

Properties of protective materials

First of all, it should be said that many finishing and building materials that are used in the construction ofenclosing structures. Moreover, the construction of the building itself implies one or another level of noise protection. For example, floor screed. Soundproofing, however, is not sufficient in this case. As a result, additional materials have to be used. To start protecting the home from the penetration of extraneous sounds, one should close up various cracks, holes, cracks. Further, in many cases, the thickening of the flooring is carried out. Here you should not overdo it with the thickness. First, the area will be lost. And secondly, such soundproofing of the floor in the house will make the entire structure of the building heavier. This, in turn, can lead to the destruction of the foundation. Therefore, many experts recommend combining soft and hard materials. Solid products include, for example, drywall, fiberboard, gypsum fiber. They do a good job of blocking out noise. Soft materials include stone or mineral wool. It perfectly dampens sound waves. With the skillful combination of different materials, you can create a quiet and cozy atmosphere in the room.

Installation of material: choice of technology

Floor soundproofing can be done in a variety of ways. The choice of one or another technology will depend on the condition of the base and the type of protective material. According to experts, the best option would be a floating floor device. The base is leveled first. For this, a screed is used (i.e., the surface is poured with a cement-sand mortar). Vibrodecoupling materials are laid on top. To theminclude, in particular, mineral wool, foamed polymer coatings.

Stages of work

Soundproofing the floor, as mentioned above, begins with sealing the cracks. As a rule, mounting foam or putty is used for this. Next, the material is laid on the prepared, clean and dry base. In this case, it is necessary to carefully glue the joints. This is especially important if the wooden floor is soundproofed using mineral wool. If gaps remain, then steam from the lower rooms will seep through them. This, in turn, will lead to rotting of the material and deterioration of its qualities. After that, along the perimeter of the walls at the junction with the floor, the material is installed vertically. It needs to be laid a little higher than the screed (subsequently, the excess is cut off). To prevent the ingress of cement milk on the material, a polyethylene film is preliminarily laid. It will provide the necessary protection against moisture. Next, beacons are installed and the solution is poured. As a rule, a mixture of cement and sand is used for screed in a ratio of 1: 3. The solution must be allowed to dry. At the end, the top coat is laid. Leave gaps around the walls. They will then hide under the plinth.

Advantages of "floating" cover

By using the technology described above, the floor is very well soundproofed.
During operation, no mechanical fasteners are used that are capable of transmitting noise.
No floating floor devicespecial equipment required. And the installation itself takes a fairly short period of time.
On such a surface, the load is evenly distributed.

Soundproofing wooden floors

To protect against noise in this case, a set of measures is used. It is also possible to build a floating floor on a wooden floor. However, the work should be carried out using a slightly different technology. When arranging sound insulation, it is necessary to create conditions in which wooden elements will not form "bridges" for noise transmission. In other words, the structures should not come into contact with each other. For this, soundproofing material must also be laid between the beams and floor joists. It should fill all free space. Another material is laid on top of the lag. It can be a cork roll coating or polyethylene foam.

Synthetic felt provides very effective noise protection. But its cost is quite high. OSB boards are laid on top of all insulation. To fix them to the lags, self-tapping screws or screws are used. During installation, it is necessary to ensure that a gap is maintained between the flooring and the walls. To do this, a damper tape or other materials that also have soundproofing properties should be laid around the perimeter. Subsequently, these areas will be covered with skirting boards. The finish coat is laid on the flooring. Very popular today is the laminate. Although it is quite possible to use other materials.

In conclusion

Systemfloating floor provides the most effective protection against the penetration of various kinds of sounds. The undoubted advantages of this coating include the absence of the need to use heavy elements and materials.
