Centrifugal glass wool blanket is roll-format material made especially for laying large area. It can be tailored into various shapes as required. As this product performs well in thermal insulation and acoustic absorption, it is applicable for places that need acoustic absorption such as theatres, TV stations, and labs, it also works well in making refrigerated warehouse and pipes of air conditioner for heat insulation. Because centrifugal glass wool has the traits of soft, minute fiber, good heat insulation, acoustic absorption, cheap cost, and short building periods, it has become the first choice of heat preservation and heat insulation.
