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.
Type:
Glass wool is divided into glass wool boards and glass wool blanket.
Application:
It was the best material used for the insulation and sound absorption of steel structures. 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.
Meanwhile, they have effect of energy-saving insulation, sound-controlling and improving the indoor air quality.
