Common glass felt and sheet
Gerui centrifugal glass wool product is a kind of heat preservation material with long and thin fiber and low thermal conductivity. Its special structure determines that it can well imprison the air, make it unable to flow, put an end to the convective heat transfer of the air, and at the same time, it can quickly reduce the transmission of sound, so as to play a role in maintaining the temperature and sound absorption. Grey centrifugal glass wool includes two series of glass wool felt and glass wool board.
Gerui centrifugal glass felt is mainly divided into two categories: non facing felt and composite facing felt. The products are widely used in factories, warehouses, freezers, gymnasiums, exhibition centers, breeding and planting heat preservation sheds, steel structure buildings and various indoor amusement parks.
Gerui centrifugal glass wool board can also be divided into two categories: non stick panel and composite stick panel. Glass wool is added to thermosetting adhesive, through pressure treatment, heating curing plate. Compared with glass wool felt, the board has more excellent and stable sound absorption and noise reduction performance. It is widely used in industrial, residential building external wall insulation system, as well as air conditioning and other fields.
