1. Introduction
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.
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.
2.Characteristics and Advantages
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.
High Strength: special formula and base materials to meet high-strength requirement.
Rich varieties: diverse holes and rich combinations to be chosen according to the sound absorption and decoration requirements.
Dry construction: short period, convenient construction, and high efficiency.
Easy decoration: simple finish procedures, and suitable for roller painting.
