Construction: Fiber glass wool is thermosetting resin is sprayed over the glass fibers to bind them together to form glass wool. The glass wool is formed into products with various thickness and densities. When the glass wool is pressed together and the volumetric weight then increases, the properties of the material gradually change. ApplicationsGlass wool blanket broadly used on Metal Building, Compartment, Ventiduct, Vent-Pipe, Industrial Building etc as soundproof, fireproof meterials and heat insulation. Product Benefits Keep room warm in winter and cool in summer, save your bills and offer you comfort,It does not contain any corrosive agent like many cellulose fibers that may corrode the metallic parts of a building. Non hygroscopic, glass wool can be used to completely fill cavity walls. Fire Safety: Glass Wool can be used with total safety in walls, roofs and air ducts. Glass wool provides both acoustic and thermal insulation unlike rigid foams which are only thermal insulators. Glass Wool does not age, does not distort and keeps its insulation capacity though the years of building life ..Roll Width: 1.1M, 1.2M Roll Length: Up to 30M Density: 10Kg/M3, 12Kg/M3, 16Kg/M3, 24Kg/M3, 32Kg/M3, 40kg/M3,48Kg/M3 Bare Glass Wool Insulation and Faced Glass Wool Insulation are available. Facing includes FSK facing,aluminum foil glass cloth, polypropylene facing etc.
