  • Patent number: 6869661
    Abstract: The present invention provides a flexible heat reflective radiant barrier that may be conveniently installed on a structure without the need to simultaneously replace rigid construction decking panels. The flexible heat reflective radiant barrier is for use as part of the outer-protective water-shedding materials of a structure or building, such as underneath shingles, tiles, or siding. At least one heat reflective layer is adhered to at least one layer of a felt roofing material. The flexible heat reflective radiant barrier may be disposed in rolls for case of storage and handling. The rolls are easily applied to rigid construction decking panel substrates, such as plywood or oriented strand board construction sheets of structural 2×4, 2×6 side walls or the like, as a part of the exterior water-shedding material.
