Abstract: A tilt-up wall panel formed on a horizontal support surface within a form comprises an outer foam layer having a top surface, and an outer surface with an outer finish layer applied thereto. An intermediate concrete layer having a bottom surface and a top surface is applied, at the bottom surface thereof, to the top surface of the outer foam layer. An intermediate foam layer having a bottom surface and a top surface is applied, at the bottom surface thereof, to the top surface of the intermediate concrete layer. A concrete inner layer having a bottom surface and a top surface is applied, at the bottom surface thereof, to the top surface of the intermediate foam layer. The tilt-up wall panel is then raised to a vertical position to form part of a wall of a building. Methods of forming the tilt-up wall panel are disclosed.

Abstract: A roofing system for protecting a building comprises a plurality of side-interlocking and front-to-back interlocking roof panels. A top side includes a front flange projecting forward at a front end. One or more gutter panels may be included, each having a top side open to a U-shaped gutter. An interior of each roof panel and gutter panel includes an insulating foam material, and an outer surface includes a rigid shell. The gutter panel is adapted for fixing along an edge of the roof at least partially under the flange of any of the roof panels that are disposed along an edge of the roof. Preferably the roofing system further includes gable cap panels, soffit fascia panels, valley cap panels, and wind breakers for holding the roof panels down to the roof in wind.

Abstract: The present device is a cutting table for supporting a workpiece above a support surface while cutting the workpiece with a tool. The cutting table is comprised of at least one foam table piece that includes a top side, a bottom side, and at least one peripheral edge. Two or more foam standoffs project upwardly from the top side of the foam table piece a common height and each terminate at a top surface adapted for contacting and supporting the workpiece. The two or more standoffs allow the workpiece, when supported by the foam table piece, to be cut with the tool even if some of the standoffs are damaged by the tool. Preferably a portion of the area of the top surfaces of the standoffs to an area of the top side of the foam table pieces is less than 50%, preferably being between either 20-30% or 45-50%.
