Product advantage
Inorganic glass fiber ducts are primarily used in construction, decoration, and fire protection fields, particularly suitable for renovations in crowded places like restaurants, hotels, and shopping malls, as well as for projects in damp environments such as basements, civil air defense facilities, and mines. Magnesia board fireproof panels are the updated and improved products replacing various materials like plywood, particleboard, MDF, and paper-faced gypsum board, and are highly recommended by the National Decoration Association as green and environmentally friendly building materials.
