Abstract: A modular panel formed by solidifying a composite mixture of material within a frame. The panel is suited for use as a structural component and multiple panels are joined together to form structural components such as foundations, floors, walls and roofs. The panels are fixedly joined as by welding the frames of adjacent panels together. The structural components are similarly joined together as by welding to form a building. The material is primarily wood products and has cement, starch and other materials as a binding agent. The material provides a surface that is suited for conventional finishing material. In addition to providing structural integrity, the panels are relatively light in weight, are not subject to deterioration and provide insulating quality.
