Все про звукоизоляцию квартиры. Монтаж межкомнатных перегородок. Часть 2

In this video, the second variant of a partition with a high air‑noise isolation index (Rw = 54 dB) is demonstrated, using a standard solution from TECHNOSONUS in collaboration with KNAUF. The partition is built with sound‑absorbing panels made of polyester fiber, a thin heavy sound‑isolation membrane TECSOUND, and a vibroacoustic sealant. The presenter explains how to choose appropriate materials for sound isolation, covering the sequence of work from floor to walls and finally the ceiling, and discusses the three main types of noise that disturb residents in multi‑unit buildings: airborne, impact, and structural. Alexander Smolin, who has more than 17 years of experience in renovation, offers practical guidance for DIY home improvement projects.
