US Patent 9957715 Structural insulated panel framing system with a radiant barrier

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