Glass fiber composite air duct is a new type of air duct developed for the application of new technologies and new materials. It is based on ultra-fine fiberboard and specially processed and compounded. It integrates many functions such as thermal insulation, noise elimination, moisture-proof and fire prevention, anti-corrosion, beautiful (suitable for open installation), high strength of the outer layer, mildew and antibacterial of the inner surface. It has the advantages of light weight, small air leakage, fast manufacturing device, small occupied space, good ventilation, reasonable function quotation, etc. In particular, its excellent thermal insulation and silencing function is biased by a wide range of users. Compared with the traditional process air duct, it can also save 20% of the investment of the pipeline system for users.

The glass fiber composite air duct is made of composite glass wool board, which is cut, bonded, sealed and reinforced with sealing tape. The double protective layer of the composite glass wool board is glass fiber cloth composite aluminum foil or the inner protective layer is glass wool board. The glass wool board is made of glass fiber and resin glue formed by centrifugal method through hot pressing and curing. Common standard of plate: density 70 ~ 75kg \ m2, thickness 25mm. Because the sandwich of composite glass wool board is porous light material, low heat seeking coefficient and large sound absorption coefficient, the glass fiber composite air duct has excellent heat preservation and noise elimination function; Together, the air duct has the characteristics of light material, short construction period, fire prevention, moisture-proof, no harmful volatiles, beautiful appearance, long service life and low cost. Compared with the galvanized steel sheet air duct with thermal insulation, the composite glass fiber air duct can save more than 30% of the engineering cost, not including the saved cost of field dissipation equipment. It is the most economical and applicable ventilation duct for low and medium pressure air conditioning and ventilation system.
