PIR Sandwich Panel
PU sandwich panels with rigid polyurethane foam core for steel building walls and roofs. Good thermal insulation, light weight and fast installation, factory-direct from China with global delivery.
PU (polyurethane) sandwich panels are composite building panels made of two pre-painted galvanized steel facings bonded to a rigid polyurethane foam core. They are widely used as wall and roof cladding for steel structure warehouses, workshops, cold storage rooms and prefabricated buildings.Key advantages: excellent thermal insulation with thermal conductivity as low as 0.022 W/(m.K), light weight that reduces steel structure load, high strength-to-weight ratio, and fast installation with tongue-and-groove joints that seal against water and dust.Standard specifications: total thickness 50 mm, 75 mm and 100 mm; effective width 950 mm or 1000 mm; steel facing thickness 0.4-0.6 mm color-coated galvanized steel; foam density 38-42 kg/m3; fire performance B1 grade; panel length customized per project up to 12 m.Typical applications: industrial warehouses, logistics centers, cold chain storage, clean rooms, workshop partitions and prefab site buildings. Panels can be combined with steel structure systems designed and fabricated in our own factory.Contact our engineering team for free design, panel layout drawings and a detailed quotation.
