Introduction
Type I AAS glass wool insulation and sound insulation board is a high-density glass wool board made of ultra-long interwoven special fibers. The fiber structure interwoven inside the board effectively absorbs the vibration and sound energy transmitted to the material. The ultra-high-density glass wool structure can provide the load required for residential floor applications. Type II AAS glass wool insulation and sound insulation board: It is a plate-shaped material composed of high-density glass wool molded from ultra-long interwoven special fibers and a waterproof breathable membrane. This composite material is used as an elastic cushion for floating floors, combining the functions of waterproofing, vibration reduction, sound insulation and heat insulation required in floating systems.
