The problem of soundproofing is especially relevant in block or panel multi -storey buildings built in the second half of the last century. In the apartments of these buildings, the architects managed to achieve unique acoustics – the slightest knock, loud voices, and even more so music easily overcome interior partitions and walls. The rapid development of the building materials industry gave rise to many ways of soundproofing walls. Many use polystyrene or polyurethane foam plates, as well as cork materials. However, when using these materials with a thickness of less than 50 mm, the soundproof effect is practically not felt. The creation of a coating of several layers of foam of the room is simply impossible, since this reduces the already not very large useful area of the room. To preserve square meters, you will need to resort to the creation of a special design and buy thermosuroisol. This is a roll material, which is a fiberglass canvas with a polypropylene coating applied on both sides and having a thickness of 8-14 mm. In addition to noise absorption, thermosuroisole prevents heat transfer and does not absorb moisture. Installation of thermosuroisol or TZI is carried out in several stages. At first, several layers of thermosuroisol are attached to the insulated wall with the help of fungal dowels. Then, a horizontal metal profile with vertical guides is installed on the sound -absorbing material. It is this frame that provides the necessary thickness of the air gap and serves as the basis for fastening drywall sheets. In cases where the area of the room is sufficient, a layer of polystyrene or polyurethane foam is added to the design with TZI. The sound insulation of the walls performed in this way will provide almost absolute silence in the room, especially if plastic windows are already installed. Among other things, thermosuroisole is one of the materials that do not threaten human health. Glass particles are securely hidden under the polypropylene shell, and toxic substances do not participate in the process of production of TZI. It should be noted that the price of thermosuroisol has long become quite affordable for a wide variety of categories of the population.
