Laminated insulation is provided that is of increased efficiency without any great increase in the total thickness of insulation used which has an internal reflector which reflects back both hot and cold air from the internal reflector. The structure includes a plurality of plastic skins with air bubbles trapped therebetween which structure is laminated to other types of insulation and may have internal provisions to increase its strength.
A laminated thermal insulation comprising a central impervious thermal insulating and reflecting layer comprising a synthetic plastic sheet formed and shaped to provide rows of air bubbles secured to at least one planar synthetic plastic sheet so as to enclose said air bubbles, panels on each side of said central layer of porous thermal insulating materials which permit air circulation therethrough, said panels being selected from the group consisting of glass fibers and foamed synthetic plastic, and an outer cover in engagement with the outer faces of s...
