Abstract
A flexible insulating laminate including a heat insulating flameproof, soft, resilient and compressible polyester blanket bonded directly at one surface to a polymer surface of a vapor barrier formed by a metallized moisture impermeable, polymer film. The bond is formed by fusion of a heat softened surface of the polymer film and a heat softened surface of the blanket. There is a stiff, high tensile strength bonding layer between the blanket and the barrier. The preferred blanket is composed of heat fused polyester fibres.
