ABSTRACT:
A modular building panel and a method for constructing the same provides a framework composed of structural members, typically formed of metal, and a backer board typically formed of a cementacious composite for receiving an exterior wall coating surface. The backer board and the framework are separated from, and insulated from, each other by a layer of foam that is applied in liquid form and that expands and cures into a solid form. Substantially no fasteners extend between the backer board and the metal framework to reduce conduction of heat therebetween. The foam serves as an adhesive to hold the backer board rigidly in place at a predetermined spacing from the framework and to anchor the backer board to the structural members. The structural members can comprise U-shaped and C-shaped channel beams for further rigidity and enhanced anchoring. Upon assembly, the backer board and the framework are overlaid upon each other, typically using spacers of a predetermined spacing thickness. Spacers can be formed from pieces of foam having adhesive or double-sided tape to maintain them in alignment with the framework and backer board. Liquid foam is applied from the interior side of the framework and expands toward the interior side of the framework.
