Complete Glasswool insulation 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.
The materials can be cut at random according to the construction requirement. It is mainly used on the following aspects: rooms of buildings, sound reduction system, mean of communication, refrigeration equipments, and sound absorption and noise reduction of domestic electric appliance, which has a satisfactory effect.
