Abstract
Abstract A flexible multilayer jacketing material for covering bare pipes or thermal insulation on pipes, etc., is a composite of an interior surface film of a metalized polyethylene terephthalate with its aluminum coated internal face bonded to one face of a central layer of glass fiber-reinforced asbestos paper which has its other face bonded to an exterior surface film of polyvinyl fluoride.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
126 words
A flexible composite laminated insulation jacket, which consists essentially of: a. a vapor barrier layer consisting essentially of a first polymeric film having deposited on the interior face thereof a thin coating of a reflective metal, said polymeric film being selected from the group consisting of polyester and halocarbon polymeric film; b. a fibrous insulating layer consisting essentially of asbestos fiber reinforced with an open mesh scrim cloth; and c. an exterior layer consisting essentially of a second polymeric film selected from the group consisting of halocarbon and acrylic polymeric films; the metal coated face of said first polymeric film being adhered to one face of said fibrous insulating layer, and the other face of said fibrous insulation layer being adhered to said second polymeric film.
Claim 2
