Soundproof floor. Sound insulation of wooden floor: materials

In life, one of the sources of constant stress is a different noise. Therefore, in the walls of their homes, I really want to stay in silence. To reduce noise, soundproofing of the floor, ceiling, walls is used. Next, we'll figure out how to protect ourselves from extraneous sounds.

General information

Up to people living in a block of flats, through the interfloor overlapping comes 2 types of sounds - air and percussion. The first to be understood is noise propagating through the air. For example, the sound of a TV or music. The shock appears from direct mechanical action on the overlap. It arises from the heels, the running of children, is heard when the furniture is rearranged. From overlapping noise spreads to the surface of walls and is transmitted to the room below. In addition, it is often disturbed by sound not only from above. In this case, properly arranged sound insulation of the floor in the apartment will save you from constant irritation and stress.

Properties of protective materials

First of all, it should be said that many finishing and building materials are used for soundproofing, which are used in the construction of enclosing structures. Moreover, the very construction of the building itself assumes one or another level of protection against noise. For example, floor screed. Sound insulation, however, in this case is not enough. In this connection it is necessary to use additional materials. To begin to protect the home from the penetration of the built-up sounds follows from the sealing of various cracks, holes, cracks. Further, in many cases, thickening of the flooring is carried out. You should not overdo it with thickness. First, the area will be lost. And secondly, this sound insulation of the floor in the house will weight the entire structure of the building. 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, plasterboard, fiberboard, gypsum fiber. They are well protected against the penetration of noise. Soft materials include stone or mineral wool. It perfectly suppresses sound waves. With the skillful combination of different materials, you can create a quiet and cozy atmosphere in the room.

Most popular products

• TEKSOUND is a heavy soundproof membrane. It is made on the basis of aragonite (mineral). The material is produced in the form of a film, the thickness of which is 3.7 mm. The product has excellent sound-absorbing properties.
• The ISOPLAAT softboard is a wood - fiber board. It is allowed to mount the material under the concrete screed. The thickness of the sheet is 25 mm.
• ISOPLAAT is an underground slab made of coniferous chopped wood. The sheet has a thickness of 5 or 7 millimeters. With the help of such boards, soundproofing of the floor under the laminate, parquet is created.
• "Shumanet" is a roll material. The product is characterized by elasticity and high soundproof performance. The coating has a thickness of 3 mm and provides protection against impact noise.
• "Vibrostek-V300" is also available in rolls. Its thickness is 4 mm. The product is applied with the device "floating screed".
• "Noisy" is produced in the form of plates. This resilient material has a thickness of up to 20 mm. It is also used in the construction of a floating floor. Plates perfectly protect from impact noise.
• ISOVER is a material based on fiberglass. Its thickness is from 50 to 100 mm. The product is used for arranging the "lag floor".

The popularity of ISOVER is very popular. He proved himself well in various conditions.

Material installation: choice of technology

Sound insulation of the floor can be carried out in various ways. The choice of this or that technology will depend on the state of the substrate and the type of protective material. According to experts, the most optimal option would be the installation of a floating floor. The base is leveled beforehand. For this, a screed (ie, the surface is poured with a cement-sand mortar) is used. Vibration-releasing materials are placed on top. They include, in particular, mineral wool, foamed polymer coatings.

Stages of work

Sound insulation of the floor, as mentioned above, begins with the closure of the slots. As a rule, for this purpose, mounting foam or putty is used. Further on the prepared, clean and dry basis is laid the material. Thus it is necessary to glue the joints carefully. This is especially important if sound insulation of a wooden floor is made using mineral wool. If cracks remain, then steam from the lower rooms will leak through them. This, in turn, will lead to the banning of material and the deterioration of its qualities. After that, on the perimeter of the walls at the junction with the floor the material is installed vertically. It needs to be laid slightly higher than the screed (afterwards the excess is cut off). To prevent the ingress of cement milk on the material, a plastic film is preliminarily laid. It will provide the necessary protection against moisture. Further, beacons are installed and the solution is poured. As a rule, for a screed a mix of cement and sand in a proportion 1: 3 is applied. The solution must be allowed to dry. In the end, the finishing coat is laid. It is necessary to leave gaps near the walls. They will then hide under the baseboard.

Advantages of a "floating" coating

• Thanks to the technology described above, very good sound insulation of the floor is provided.
• In the course of work, mechanical fasteners that are capable of transmitting noise are not used.
• For the device of a floating floor it is not required the special equipment. And the installation itself takes quite a short period of time.
• On such a coating, the load is evenly distributed.

Sound insulation of wooden floors

To protect against noise in this case, a set of measures is used. On the wooden floor, you can also build a floating covering. 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" of noise transmission. In other words, the constructions should not contact each other. To do this, soundproof material must be laid between the beams and the lag bars. It must fill all the free space. On top of the log lay another material. They can become cork rolls or foamed polyethylene. A very effective protection against noise is provided by synthetic felt. But its cost is quite high. The OSB boards are laid on top of all insulation. To fix them to the logs, self-tapping screws or screws are used. At installation it is necessary to watch, that between a flooring and walls the backlash remained. To do this, along the perimeter should be laid damping tape or other materials that also have soundproofing properties. Subsequently, these plots will be covered with skirting boards. On the flooring is laid the finish coat. Very popular today is laminate. Although it is possible to use other materials.

Finally

The floating floor system 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-weight elements and materials.
