Product details
Youshi brand glass magnesium compositeair duct
Youshi brand glass magnesium composite air duct is a new type of high-tech composite board. The product is made of high-quality magnesium oxide, magnesium chloride, alkali resistant glass fiber cloth and inorganic adhesive rolled by modern technology. It has the characteristics of light weight, high strength, non combustion, sound insulation, heat insulation, moisture resistance, water resistance, and long service life. It is a new generation of energy-saving and environmentally friendly green products.
Youshi brand glass magnesium composite air ducts are mainly used in construction, decoration, fire protection and other fields, especially suitable for the decoration of crowded places such as restaurants, hotels, shopping malls, as well as projects in damp environments such as basements, civil defense and mines. Glass magnesium fireproof board is an updated product that replaces various plywood, density board, particleboard, paper faced gypsum board and other boards. It is a green and environmentally friendly building material recommended by the National Decoration Association. The glass magnesium composite air duct has been tested by the National Building Materials Testing Center and the National Quality Supervision and Testing Center for Fixed Fire Extinguishing Systems and Refractory Components. Its physical properties meet the technical requirements of qualified products in JC/T646-2006 standard, and its combustion performance reaches GB8624A level.
