Everyone who lives in a multi-storey building knows how late the noise coming from the apartment is from the top. Therefore, I do not want to be in an awkward situation, delivering similar inconveniences to neighbors from below. And in order to feel comfortable in your own apartment, during the overhaul, noise insulation of the floor under the screed is made .
Good noise insulation of the screed is achieved by arranging the "floating" floor. Its feature is the lack of connection of the flooring with inter-floor overlapping and walls, which provides the necessary effect.
Sound insulation for screed - materials
To achieve maximum noise protection, a sound-absorbing material is placed in the multi-layer construction of the floating floor. To do this, the soundproofing located between the logs is poured from above with a concrete floor screed.
The most common and effective materials for soundproofing are:
- Soft board ISOPLAAT is characterized by an index of sound insulation in 26 dB. This material is a wood-fiber soft board with a thickness of 25 mm;
- ISOPLAAT floorboard is made from sawdust of coniferous trees and is recommended for noise insulation of a floor screed with a finish coating of laminate or parquet. With the help of such boards the level of sound insulation of air noise in 21 dB is reached;
- SHUMANET is made of basalt fibers in the form of elastic plates with a thickness of 20 mm and an acoustic insulation index of 23 dB;
- SHUMOSTOP has very high soundproof characteristics. It is able to isolate air noise in 39 dB. And make it in the form of elastic glass-fiber plates with a thickness of 20 mm.
With the right selection of materials and the organization of a "floating" floor, the maximum sound insulation from neighbors from the bottom will be guaranteed.
