Abstract

Abstract An improved prefabricated modular building panel includes a three-dimensional lattice fabricated of a plurality of rod-like slender elongated metal elements. The lattice elements are arranged to define a pair of substantially parallel spaced major lattice surfaces, and side and end lattice edge surfaces. A plurality of strut members traverse the interior of the lattice and interconnect the major surfaces to define a plurality of passages within the lattice. The passages are open at at least one end thereof to one of the lattice edge surfaces. Thermal insulating filler material is disposed within the lattice and extends from side to side and from end to end of the lattice. The filler material includes a plurality of insulative elements positioned in the passages through the passage open ends to be disposed wholly within the lattice. A bonding agent is used to secure the insulative elements in position within the lattice, and the bonding preferably is a layer of foam material applied over the insulative elements within the lattice to foam at least partially in situ and to bond to the insulative elements and to the metal elements of the lattice, particularly the lattice strut members.
