Abstract: A modular wall panel for manufacturing an exterior wall is made from a substantially flat rectangular insulating foam core having two opposite surfaces, two opposite side edges, a width defined by the opposite side edges, opposite top and bottom edges, and a length defined by the top and bottom edges. The panel also has at least one elongated longitudinal support stud and at least one elongated transverse stud, each mounted to the foam core. The first side edge of the panel has a first face extending between the opposite surfaces and the second side edge has a second face extending between the opposite surfaces. Each face defines an elongated first channel when the first face of one panel is abutted against the second face of an adjacent panel and the first channel has an elongated first cavity and an opening extending to the first surface of the panels.

Abstract: A modular wall panel for manufacturing an exterior wall by abutting a plurality of said wall panels in side to side alignment is disclosed. Each of said wall panels consists of a substantially flat rectangular insulating foam core having first and second opposite surfaces, first and second opposite side edges, a width defined by the opposite side edges, opposite top and bottom edges, and a length defined by the top and bottom edges. The panel also has at least one elongated longitudinal support stud mounted to the foam core between the first and second side edges. The longitudinal stud extends substantially the length of the foam core between the top and bottom edges, and extends parallel to the side edges. The panel also has at least one elongated transverse support stud mounted to the foam core substantially perpendicularly relative to the longitudinal support stud, said transverse support stud extending between the opposite side edges.
