Glass wool and mineral (rock) Cotton belong inorganic insulation materials. The molten glass wool is treated with flame, centrifugation, pressure gas method can set other technical fiber Dimension of from. The mineral (rock) is based on iron slag cotton as the main raw material, melting, cooling with high-pressure steam injection is made. Meanwhile both, also has absolutely Excellent noise performance. Glass wool and mineral (rock) Cotton core except for the normal activities of structural insulation from the outside, they are more widely used in a variety of fire insulation should be places such as office partitions, dance halls, shopping malls, stadiums and other places decoration well as the studio, recording studio soundproofing, drying room and so on.
