摘要：
Method for producing a reflective, waterproof, water-vapor permeable membrane, comprising the following steps,Provision of a waterproof, water-vapor permeable membrane,Provision of a carrier foil,Application of the membrane onto the carrier foil,Application of a metal surface onto the membrane's free surface via a vacuum sputtering process,Application of a waterproof, water-vapor permeable cover layer,Removal of the carrier foil.Reflective, waterproof, water-vapor permeable membrane with a metal coating, which is provided with a continuous cover layer, characterized in that at least 80% of the surface of the active metal coating is retained on the membrane after 3 washings according to DIN EN ISO 6330:2000.
