US Patent 10294668 Stiffened foam backed composite framed structure

A foam backed composite framed structure is substantially stiffened by reconfiguring some of the foam backing from a dropped section, between the frame members, to a continuous section above the frame members. The framed structure is comprised of a foam backed panel, which is a cladding with a foam backing, that is adhesively bonded to frame members. The thicker the continuous section of foam, the stiffer the framed structure. Since the frame is bonded to the cladding by the continuous section of foam, it eliminates the need for nails or other fasteners and thereby eliminates the thermal bridges caused by such fasteners. This results in a stronger structure with increased thermal insulation and fewer frame members.
