1. An improved prefabricated sidewall panel for the construction of an energy efficient modular building, said panel defining a perimeter and first and further substantially planar surfaces spaced apart a first selected distance, said panel comprising:

  • a primary frame fabricated of members to define said panel perimeter and further define first and further substantially planar surfaces spaced apart at a distance less than said first selected distance, said primary frame including a top member, a bottom member, and a pair of vertical support members each joined at their extremities to said top and bottom members proximate opposite ends of said top and bottom members;

    a secondary frame of furring strips attached to said primary frame at selected locations with suitable fasteners, said secondary frame defining said first planar surface of said panel; and

    foam insulation formed in place throughout interstices of said primary and secondary frames of said panel to further define said first and further planar surfaces of said panel and so as to integrally fill said primary and secondary frames between said first and further planar surfaces of said panel and thereby prevent thermal bridging between said first and further planar surfaces.
