Heat insulating laminate

Patent ·
OSTI ID:5926958
The disclosure concerns a heat insulating laminate which is comprised of a contractile thin film, a first noncontractile metal reflecting thin film at at least one side of the contractile film and at least a second noncontractile metal reflecting thin film beyond the first one of those films. Adjacent films are bonded together at scattered areas. In one version, the density of the bonding areas between the contractile film and the first noncontractile film is greater and the density of the bonding areas between successive noncontractile layers away from the contractile layer decreases stepwise. Shrinking of the contractile film causes wrinkles in the noncontractile films. An additional protective film may be laminated to the contractile film.
