ABSTRACT:
As a flexible composite insulation, a layer of mass type of insulating material of low heat conductivity is bonded to a multilayer protective jacket. The mass insulation layer is flexible in at least one direction for fitting pipes, etc., and it is preferably a series of parallel contiguous strips of fiber glass or mineral wool batt insulation cemented to the vapor barrier layer of the jacket with their fibers substantially oriented in parallel planes aligned perpendicularly to the jacket. The jacketing material is preferably a combination of vapor barrier film of a metallized polyethylene terephthalate with its aluminum coated face bonded to one face of a layer of glass fiber-reinforced asbestos paper which has its other face bonded to an exterior surface film of polyvinyl fluoride.
