Abstract: An integral energy efficient load-bearing exterior wall fabricated of light-weight foam surrounding plastic load-bearing columns. The invention relates to pre-fabricated modular wall panels as individual building elements and as part of an integrated building system. In a preferred embodiment, a prefabricated modular wall panel is made from a foamed material that is molded around a plurality of vertically disposed hollow support columns. Each of the columns contains a pair of opposed and vertically disposed T-shaped fastening supports which are arranged to form part of the interior and exterior surfaces of the foamed wall. The hollow columns are set onto locking base plates which are mounted on a wood or concrete deck system. Locking top plates are also mounted on wood and are then placed on top of the columns. The tubular columns are made of a plastic material and are shaped in cross-section in the form of a rectangle, square, diamond, oval or circle.
