Description
Qingdao Yunda metal-faced insulated roofing sandwich panels combine profiled metal facings with a high-performance insulation core to provide thermal insulation, sound reduction, weather protection and reliable roof strength in one prefabricated building component.
The panels are available with PU, PU + glass wool, or PU + rock wool composite cores, allowing the insulation and structural configuration to be selected according to different project requirements. Their multi-wave profiled exterior surface improves panel rigidity and roof drainage, while the overlapping joint incorporates an air-chamber waterproof structure to help reduce rainwater penetration.
With lightweight construction, prefabricated dimensions and efficient overlapping installation, the roofing system can shorten on-site construction time and reduce structural loading. Different panel thicknesses, effective widths, metal facings, coatings and colors are available for industrial buildings, warehouses, logistics facilities, commercial buildings and prefabricated steel structures.
Product Features
The metal-faced roofing sandwich panel integrates the external roof surface, insulation layer and internal finish into one factory-produced panel. Depending on the selected model, the system can use steel, aluminum or steel-and-aluminum-foil facings together with polyurethane and composite insulation materials. The reference product range reports thermal conductivity of 0.020–0.040 W/(m·K) and panel weight of approximately 15–30 kg/m²
