Everyone dreams that his house is the most comfortable and comfortable for him. But, unfortunately, sometimes such dreams are broken against the harsh reality. In it, the neighbors can arrange a party at home with music and dance until the morning, start repairing and endlessly work as a perforator, and from the street you can hear traffic of cars, trams and trains. Therefore, the question of how to make noise insulation of walls in an apartment is set by almost every second resident of a multi-storey building. This can be done with a variety of materials . And what they are, and how they differ from each other, you will learn in our article.
Materials for noise insulation of walls
Sound absorbing materials are considered to have an absorption coefficient of at least 0.2. For example, brick and concrete are very dense and have the lowest absorption coefficient from 0.01 to 0.05. In order to ensure good noise insulation of walls in the apartment, it is necessary to use a homogeneous porous structure material that has a certain thickness and is attached to the surface tightly to each other friend.
One of the most popular sound absorbers to date is mineral wool , which has a soft air-cellular structure, so that rolls and slabs of mineral wool muffle sound waves, preventing them from spreading around the house. The sound absorption coefficient of such a soundproofing device is the largest and amounts to 0.7-0.85 (200-1000 Hz).
Also, one of the no less effective materials for noise insulation of walls in the apartment are semi-rigid slabs and rolls of glass wool . This material is made from waste glass industry, but according to the characteristics, it is almost inferior to mineral wool. The coefficient of sound absorption of glass wool is - 0,65-0,75. It should be remembered that the laying of fiberglass requires compliance with safety regulations, because microscopic glass fibers can cause great harm to your body. Therefore, during work with such material, you should always wear protective goggles, a mask and gloves.
More budget option for noise insulation of walls in the apartment is the use of fibreboard. Their noise absorption coefficient is the same as glass fiber. At the same time, super-hard fibreboards are made from wood shavings, and it is considered a rather profitable and affordable alternative to all other sound absorbers.
Such a natural material as cork allows you to rid the house of the effect of "fluttering echoes" of booming, reduces the level of impact noise. However, using this material to noise-proof the walls do not need to wait for significant changes and silence in the house. After a cork can absorb sound only next to its source. That is, if you turn your cinema to full volume, then it will not hurt neighbors. But the noise, heard at the entrance from the working elevator to you still come. So if you decide to make a cork soundproofing at home, it's worth considering this issue together with a specialist.
And, of course, the most common material for noise insulation of walls in the apartment are polyurethane, polyvinylchloride, polyester, foam , having a cellular structure. Such noise isolators are produced in the form of slabs with a thickness of 5-30 mm, which are fairly easily fixed on the surface with the help of adhesive-containing building materials. The sound absorption coefficient of these synthetic materials is - 0,65-0,75, and this is a fairly good indicator. In addition, all these materials, in addition to noise insulation, provide heat retention in the room.
