Abstract: A layered composite construction material includes a pair of outer layers of material including essentially continuous strand fiberglass mat which are separated by a pair of intermediate sandwich layers of material each being adjacent to a respective outer layer of material and including essentially eighteen ounce woven roving fiberglass mat and which are further separated by at least one internal layer of material which essentially includes spun fiberglass blanket which has fiberglass strands longitudinally disposed perpendicular to the other layers of material for facilitating even dispersal of a foam throughout all the layers of material to effectively secure and bind the layers of material. The internal layer of material can also include multiple layers of spun fiberglass mat each of which are separated by a pair of layers of material.

Abstract: A floor structure for use on an ice surface includes sheets of rigid, lightweight material each having a topside and a bottom side which includes a margin and geometric recesses and recess dividers. Only the margins and recess dividers are in contact with the ice surface when this floor structure is laid upon the ice. The recess dividers effectively seal the geometric recesses creating sealed pockets which trap ambient air thus creating a thermal insulating effect which substantially prevents the coldness from the ice from penetrating the sheets to the topsides and prevents condensation from forming on the topsides making it safe for the users to move about upon this floor structure unlike other floor structures which are used on ice. In addition, this floor structure does not stick or freeze to the ice unlike the other floor structures, because it has a substantially smaller surface area which is in direct contact with the ice, making it much easier to remove and reuse.

Abstract: This invention relates to a mixed composition for making structural building materials or articles; wherein the composition comprises a prepared or reprocessed solid or sludge waste material such as impure lime obtained, in particular, from water treatment plants, and further comprises a reinforcing material such as fiberglass, metal material, sisal fiber, or plastics, and also comprises a polymeric material which preferably includes polyurethane foam. A coloring agent is added the composition to give a distinctive color to the structural building materials or articles such as shingles, panels, sidings, walls, and logs, all replicating products made especially from wood.
