The walls of large industrial and refrigeration buildings, cold stores, warehouses, exhibitions and sports halls, schools and other large buildings are best built on the components that provide thermal insulation while also meeting other technical requirements such as stability , free assembly, freedom from maintenance and ease of disassembly and reconstruction.Isometal has found the optimal solution for these applications with its sandwich panels with polyurethane with metals. On prefabricated exterior walls and lightweight components, a hard foam zone joins the metal panels together in a shock-resistant manner, as the rigid polyurethane foam bonds strongly to the surface during the foaming process.
