The Centrifugal Glass Wool Blanket/Felt/Roll and Board are excellent heat preservation and sound absorption material for steel structure, ceiling, outer wall, partition wall, train compartment, air duct, etc. It features:
1. Excellent for heat preservation, thermal insulation, sound absorption;
2. Non-combustible, nontoxic, and resistant to corrosion;
3. Low thermal conductivity, stable chemical property, low moisture rate and good hydrophobicity;
4. Low weight by volume, good rebound elasticity;
5. Low constructional cost, short cycle of works, non-stimulation to the skin.
Owing to glass wool's good performance, e.g., thin and long inner fiber, low thermal conductivity, it can stop air flowing and heat transforming. Meanwhile, it can quickly reduce the transportation of sound to make effects of insulation and sound absorption. Centrifugal glass wool is divided into glass wool boards and glass wool blanket.
It was the best material used for the insulation and sound absorption of steel structures. It mainly includes bare blanket with foil-clad covered. They are widely used in industrial plants, warehouse, public facilities, exhibition centre’s, shopping centers, cold shores and a variety of indoor playgrounds, sports grounds and other buildings.
Glass wool board is processed by putting the thermosetting binder into the glass wool, by pressing and heating, and then, by curing. They are used for insulation, ventilation and adjustment of air-conditioner in commercial industry and residential constructions. Meanwhile, they have effect of energy-saving insulation, sound-controlling and improving the indoor air quality.
