Patent ID: 8607520

Claim:
A thermally-reflective panel assembly for use in a structure, the panel assembly comprising: an exterior panel having opposing outer and inner surfaces separated by exterior panel edge surfaces; an interior panel having opposing outer and inner surfaces separated by interior panel edge surfaces that are aligned with the exterior panel edge surfaces, the outer surface having an outer surface area and the inner surface having an inner surface area; an intermediate framework made from a thermally insulative material, said intermediate framework fixed to the inner surfaces of the exterior panel and the interior panel to define a plurality of closed compartments between the exterior an interior panels, said intermediate framework comprising: an outer flame having first and second sets of opposing ends and flame surface edges; a plurality of elongate first members extending between the first set of opposing ends, wherein each first member is spaced a distance from every other first member of said plurality of elongate first members and from the second set of opposing ends; a plurality of elongate second members extending between the second set of opposing ends and intersecting said plurality of elongate first members, wherein each second member is spaced a distance from every other second member of said plurality of elongate second members and from the first set of opposing ends; and wherein the pluralities of elongate members partially define the plurality of compartments; and wherein the frame edge surfaces are misaligned with the exterior panel edges and interior panel edges to define a tongue extending laterally from at least one side of the assembly and a corresponding groove in at least one opposing side of the assembly; a first layer of metallic material fixed to the inner surface of the interior panel; a second layer of metallic material fixed to the outer surface of the interior panel; and wherein the inner surface of the exterior panel and the inner surface of the interior panel partially define the plurality of closed compartments.
