Product Details
Perforated Gypsum Board adopts special high-strength paper-faced gypsum board as basic material. Special intensifying materials are added into the core board to ensure the intensity. The raw board is made into perforated gypsum board through the processes of perforating, cutting, fiber film coating, which is the ideal product for the sound absorption of wall and ceiling. Remarkable effect on sound absorption: the perforated board can absorb the sound wave energy, and effectively adjust the indoor reverberation time through the combination of different apertures, dimension, perforation rate and cavity, especially for the low frequency sound wave. It is suitable for all the industrial and civil buildings with the requirements of adjusting the reverberation time, improving the indoor acoustic effect, and reducing the noise, such as cinemas, theaters, concert halls, auditoriums, conference rooms, multi-function rooms, home theaters, music rooms, studios, etc.
