Centrifugal Glass Wool Board is made by adopting unique centrifugal technology and adding environmental adhesives of thermosetting resins-based into molten glass fibrosis. It is a kind of elastic glass fiber product made of glass fiber with diameter of only a few microns, and we can also choose moisture-proof facing on-line compound according to customers' requirements. Because of a large number of tiny air interspaces, it has the functions of heat insulation, sound absorption, safe guarding and etc, so it is the best materials of heat insulation and sound absorption in construction. Distinctive advantages: • Sound absorption and noise reduction; it can effectively prevent sound from spreading. • Easy for construction; cutting at will. • Antisepsis, ageing resistance, and anticorrosion, ensuring a healthy environment. • Grade A1 fireproof; incombustible permanently. • Low moisture absorption; stable physical properties. • Strong vibration resistance and high durability. Scope of application: It is widely used for heat insulation and sound absorption in heat supply, ventilation, tank, and air-conditioning regulation of a variety of commercial, industrial and residential constructions.
