Patent attributes
A framing system comprises an exterior siding and structural frame elements. The structural frame elements are arranged against a first side of the exterior siding, and are evenly spaced along the exterior siding thereby creating a plurality of structural element cavities. A radiant barrier with an emissivity of less than 0.50 is disposed between the exterior siding and the elements, and includes a plurality of indented portions, each indented into a corresponding cavity thereby creating a respective first sealed air space between the exterior siding and the radiant barrier in each structural element cavity. Each cavity comprises a polyurethane foam overlaying the indented portion of the radiant barrier bounded by the respective cavity. An interior siding covers the barrier and is attached to the elements thereby creating a respective second sealed space between the barrier and the interior siding in each structural element cavity.
