Overview

Composite perforated sound-absorbing panel:

The materials meet the national environmental protection standards, and the composite perforated sound-absorbing panels have the highest fire rating A1. Has been tested by the national authority. The composite perforated sound-absorbing panel is a structural sound-absorbing material with round holes on the front of the fiberboard. Commonly used in ceiling wall decoration and sound absorption and noise reduction. According to the principle of acoustics, the science and technology industry cooperates reasonably and has excellent noise reduction and sound absorption performance, especially for medium and low frequency sound absorption. the
