Glass wool sandwich panel consists of glass fiber and 2 layers of steel sheets. Glass wool sandwich panels are excellent choice for heat insulated roof and wall cladding of industrial and commercial buildings. Material a) Surface/base plate material: Prepainted galvanized steel sheet Galvanized steel sheet Galvalume steel sheet b) Core material: Fiber Glass/Glass Wool Thickness a) Thickness of Surface/base plate: 0.12mm-3.0mm b) Thickness of Core: 50/75/100/125/150/200 mm Core Density 40-60kg/m2 Effective Width For Roof: 960mm, 980mm For Wall: 950mm Characteristics of Glass wool sandwich panel Heat insulation capability. The heat insulation capability of the Glass wool sandwich panel depends on the specifications of the filling material. Good fire performance. Glass wool sandwich panel is fire rating of non-combustible A grade. Its shape, strength and material are hard to be changed in the fire, it can protects your valuable life and properties. Sound insulation and Sound absorption capability. Sound insulation is a physical value what shows the rate of sound energy decrease on the one side of a surface (e.g. wall or roof cladding), while the noise source is on the other side. Sound absorption values of panels can be increased by applying perforated internal armouring and mineral wool insulation core.
