Glass Wool with Stable Quality for Insulation Properties
Glass wool is made from borosilicate glass whose principal constituents are sand, soda ash dolomite, limestone, ulexite and anhydrite. They are melted in a furnace at about 1400°C and then fed along a channel to a forehearth, where the glass flows through bushings into spinners.
lass wool products have a limiting temperature of 540°C but are mostly used in buildings and H & V applications where a limiting working temperature of 230°C is recommended.
Acoustic absorption in duct lining and splitters. Decorative facings for ceiling and lining panels. Tensile strength for good draping qualities. Loft insulation up to 200 mm thick, cavity wall insulation. Fire stopping and small-cavity fire barriers.
