Abstract: A prefabricated asphalt-based waterproof roofing membrane for use in a multi-ply asphalt-based commercial roofing system, e.g. a cap sheet that forms the exposed layer of a multi-ply built-up roofing system, is manufactured at a factory to have a highly reflective non-asphalt based elastomeric top coating layer with an upper surface that meets current EPA Energy Star requirements. Preferably, a polymer primer layer is interposed between the highly reflective coating layer and an asphalt saturated and coated reinforcing substrate to keep oils and other colored components in the asphalt from exuding into the highly reflective coating layer.

Abstract: A perlite-based insulation board includes, by dry weight, between about 50% and about 76% expanded perlite; between about 15% and about 45% fibers; between about 1% and about 5% starch; between about 2% and about 9% bituminous material; and about 0% to about 3% alum. The fibers are between about 50% and about 95% by dry weight recycled newsprint fibers and between about 5% and about 50% by dry weight virgin cellulose fibers, such as flax and/or peanut hull fibers. In one embodiment, the virgin cellulose fibers are, by dry weight, between about 10% and 40% flax fibers and about 60% and 90% peanut hull fibers.

Abstract: A floor covering material with enhanced chemical, particularly acid, resistance containing refractory oxide, asphaltite, high oil asphalt, asphalt with a softening point in the range of about 210.degree.-230.degree. F., reinforcing fiber, crystalline polyolefin polymer and optionally, non-crystalline polyolefin polymer. The disclosed floor covering material is single-layered.
