Glass wool has four levels of fire protection, namely level A non-flammability, level B1 flame retardancy, level B2 flammability, and level B3 flammability.
Glass wool is made of centrifugal glass wool felt, which is processed using Owens Corning's unique patented centrifugal technology to fiberize molten glass and add an environmentally friendly formula binder based on thermosetting resin. products. It is an elastic felt-like body made of glass fibers with a diameter of only a few microns. Different moisture-proof veneers can be selected for online lamination according to usage requirements.
It has a large number of tiny air pores, which makes it play the role of thermal insulation, sound absorption and noise reduction, and safety protection. It is the best material for thermal insulation, sound absorption and noise reduction of steel structure buildings. . It belongs to a category of glass fiber and is a man-made inorganic fiber.
Main features of glass wool
1. The sound absorption characteristics of centrifugal glass wool are not only related to thickness and bulk density, but also related to factors such as covering material and structural structure. In construction applications, it is also necessary to take into account many aspects such as cost, aesthetics, fire protection, moisture resistance, dust, and aging resistance.
2. Cut at will, anti-bacterial and mildew-proof, resistant to aging and corrosion to ensure a healthy environment, and can be cut and shaped at will.
3. Passed the Australian and New Zealand AS, NSZ4859.1 certification, SGS certification, MSDS certification EU, CE certification, CE fire protection grade certification national standard GB, T13350-2000 applicable scope used in industrial plants, warehouses, companies Thermal insulation, sound absorption and noise reduction of government facilities, exhibition centers, shopping malls, various indoor playgrounds, sports venues and other buildings.
4. The internal fibers are fluffy and intertwined, and there are a large number of tiny pores. It is a typical porous sound-absorbing material and has good sound-absorbing properties.
