Abstract
Abstract A thermally and sonically insulating and weatherproofing cover for the roofs of mobile homes or like buildings comprises preformed or molded-in-situ slabs of expanded polystyrene bonded to the original roof surface, and a Neoprene-impregnated-fabric lamina stretched over the slabs and having downturned margins fastened to the upper side surfaces of the side walls of the building. The lamina margins are preferably provided with reinforced selvages having grommets to receive screws to fasten the lamina in place. An obtuse-angled trim strip desirably is employed to cover the grommets and screw heads. A gutter channel may be provided and be positioned to receive the lower edges of the lamina and the trim strip.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
104 words
A laminated cover for thermally and sonically insulating and weather-proofing the roof of a mobile home or like building, said cover comprising: an at least one-inch-thick flexible blanket of hail-shock-absorbing and thermally and sonically non-metallic material for covering the original roof surface to be protected, and a relatively thin lamina of flexible water-proof non-metallic material overlying said blanket, at least the upper surface of said lamina being highly reflective of radiant energy, the margins of said lamina being underfolded and adhered to provide a reinforced selvage for fastening to the upper surface of a building, said selvage having screw-receiving grommets at spaced points therealong.
Claim 2
Dependent Claim
104 words
