CAS-AP high performance fireproof damping sound insulation felt adopts multi-layer composite structure. Its upper and lower layers are flexible and fluffy high performance aluminum magnesium fiber sound insulation layer,the middle layer is fire resistance mud insulation layer. Through the combination of sound absorption and sound insulation, it can effectively convert the acoustic mechanical energy into the low level of friction heat energy, thus greatly reducing the noise decibel, and giving you a quiet and comfortable living and working space.(1.Contains no harmful substances such as asphalt and benzene 2.Contains no substances such as formaidehyde or halogen that generate harmful gases at high temperatures 3.It can simultaneously dampen sound insulation and heat insulation 4.Effectively combine the sound absorption and sound insulation )
