4, application
used for the heat insulation and sound absorption in building roofs, Movie theatres, TV Station, Broadcasting & Radio, testing laboratory, Sound absorption setting, cooling air conditioning pipes and insulating heat in cold storage and warehouse
Glass wool board is in rectangle with many choices of unit weight. The heat insulation materials are usually using "2b" centrifugal glass temperature keeping board, the average diameter of fibre is around 7 micron with the types of faced or no face for all. With the features of light, wear and tear resistance and tenacity, it satisfies the heat insulation requirements. It can save the energy, reduce heating wastage and cut the cost, if build it correctly, the transmission of sound wave can be reduced effectively. It is the unearthly sound absorbing and warm keeping material. It has been widely applied for heat insulation of house wall, compartment; Temperature keeping of computer rooms, refrigerator; Denoise of power plants and pump rooms; Adjustment of Hi-Fi etc.

Glass wool pipe shell is antisepsis, non moisture absorption, no smiley, no moldy with no germs propagation. The materials are suitable for temperature keeping of heat pipes, cooling pipes, hidden and outside pipes. It has passed the all the indexes of incombustible materials in standard GB/T5464-1999. Effectively prevent the cooling, pipe freezing and pipe noise controlling by using the thickness and surface materials with attention in the sealed processing between joints.
