Abstract
Abstract The disclosure relates to a building formed of a plurality of modular units, a modular unit, and methods of constructing said module. Each building module comprises two portions, a first inner portion, which coacts with identical first portions of a plurality of other modules to form a common open area for said building, and a second portion which comprises a wing of the finally assembled building. Two methods of forming the modules are disclosed. Each module is a molded construction with an inner and outer shell and a foamed insulating material therebetween. In one method the insulating material is foamed in place. In the second method, a mat of fiberglass and foam blocks is formed wherein the fiberglass matting forms a truss for the wall structure.
