Now many school places, such as classrooms, gymnasiums, auditoriums, large conference rooms, etc., require acoustic decorative materials to pass fire-fighting inspections and have fire-proof inspection reports, which involves the flame-retardant performance of sound-absorbing panels. Fire-resistant wooden sound-absorbing panels can be divided into two types, A and B1, of which B is self-extinguishing away from the fire, and A is non-combustible. In order to attract customers, many manufacturers of flame-retardant sound-absorbing panels do not hesitate to fight a price war. The price of flame-retardant sound-absorbing panels is generally divided into three levels, namely A, B1, and B2. Because the core material and the wood used are different, the fireproof grade is also divided into different levels. When we choose the fireproof sound-absorbing board, we must have a clearer concept of its fireproof grade. .
Classification of fire-proof sound-absorbing panels Fire-proof sound-absorbing panels can be divided into grades A1 and B1 according to different grades. Class A1 fireproof sound-absorbing panels are mostly used in public places. It has high fireproof level, good sound-absorbing effect, and has no poisonous gas and no peculiar smell when burned.
