Glass fiber absorbing noise panels, high-density fiberboard for the glass substrate, the choice of surface paint. fiberglass lining and the thin glass product with a built-in a unique appearance quality.
Fluent appearance : According to high-quality ceiling and indoor designed to cover different surface treatment, can be applied to different forms of suspension system. Their music hall, offices, sports stadium or in hotels, industrial plants can achieve the best results.
Sound absorption properties : Glass fiber is the
best one of the absorbing material. It can reduce the indoor Echo (to shorten response time)and reduce noise relative index, This is a comfortable environment of the important factors.
Fire Performance : Architectural Decoration Material properties for the fire to ensure the safety of the building, is extremely crucial, products are under strict GB8624 test for Grade A combustion materials.
Safe and convenient : a high-quality decorative glass ceilings in the installation of sound-absorbing panels will be very convenient, no indentation, cutting convenience. In the ceiling structure, can be arbitrarily open to the ceiling in the replacement of electrical equipment maintenance.
Moisture resistance properties : Glass fiber absorbing noise panels will not absorb moisture the air can not produce capillary action, Allow ceiling surface water cleans. Excellent moisture resistance properties of the product can Natatorium higher humidity and other places used in the premise.
Technical parameters : The absorption coefficient (GBJ47-83) = 0.90 NRC fire rating (GB8624-1997) Grade A (combustion materials)
absorption coefficient test : (385 mm cavity)
