Composition of a radiation reflecting breather membrane

Abstract

Composition of a radiation reflecting breather membrane, characterized in that it consists of two composed layer packages, respectively an outer layer package and an inner layer package, which are fused, whereby the outer layer package comprises a monolithic polyethylene (PE) layer and a metallic or metalized radiation reflecting layer on the outside and a substrate layer on the inside, whereby this outer layer package is perforated, and whereby the inner layer package comprises a monolithic layer with a thickness (A) of less than 100 micrometer of extruded thermoplastic polyurethane (TPU) or thermoplastic polyester-ether (TPEE) fused to the substrate layer of the aforementioned perforated outer layer package.

Dependencies are inferred from the claim text.
