Multilayer insulating complex for inner face of building roof, has several layers assembled by welding lines which alternate with non welding zones in which layers are free, where each line is near to longitudinal edge of complex
Multilayer insulating complex for inner face of building roof, has several layers assembled by welding lines which alternate with non welding zones in which layers are free, where each line is near to longitudinal edge of complex
The complex has thirteen layers split into two external metal-coated polyester layers that confines a core constituted of six cotton layers between which five aluminized polypropylene layers are intercalated. The layers are assembled between them by welding lines (7) which alternate with non welding zones in which the layers are free between them. Each welding line is formed at proximity of a longitudinal edge of the complex.
