Abstract
Abstract An insulated building has an inner structure forming the interior walls and roof of the building. Elongated wood spacer members are mounted on the exterior of the inner structure preferably with insulated fasteners. The spacer members are spaced from the exterior of the inner structure. Foam insulation covers the exterior of the inner structure to a depth generally flush with the spacer members. Sheeting is applied over the foam to cover the exterior of the building. The building is characterized by an absence of panel joints typically found in buildings of this type. Such joints permit detrimental heat transfer through the insulation.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
162 words
An insulated building comprising: an inner structure forming the interior walls and roof of the building; spacer means mounted on the exterior of said inner structure, said spacer means extending at intervals along the walls and roof of said inner structure and comprising elongated members, said elongated members being located at a distance from the exterior of said inner structure, said elongated members being mounted on said inner structure by fasteners, so constructed as to avoid a heat transfer path through the insulation, said fasteners being applied at intervals along said elongated members; insulating foam covering the entire exterior of said inner structure except for the areas occupied by said fasteners, said insulating foam covering to a depth generally flush with the outer edges of said spacer means, said foam embedding said spacer means and forming a seamless, integral insulation for the building; and sheeting applied over said foam and spacer means to cover the foam on the exterior of the building.
Claim 2
Dependent Claim
