Abstract
Insulation material includes a fibrous material and a low conductivity gas sealed within a casing made from one or more heat sealable laminate sheets. The fibrous material is partially secured to the inner surface of the casing with adhesive means. The laminate sheets each comprise at least two thermoplastic films reinforced longitudinally with glass fibers comprising at least 2% by volume of the thermoplastic films. The films are bonded together orthogonally so as to produce a biaxially reinforced sheet. One or more ductile low conductivity abrasion resistant thin metallic films are deposited over substantially all of one or both sides of the biaxially reinforced sheets.
