Abstract
Abstract Heat or cold and sound and condensation insulation for mounting on planar surfaces such as, for example, the roof of a trailer home, comprises a series of abutting blocks of closed cell polystyrene which have their lower surfaces cemented to a polyvinyl-chloride base. The upper exposed surfaces of such blocks are grooved to accept flexible fastening belts or straps which have their ends releasably secured to rails mounted on the roof.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
90 words
A heat or cold and sound and condensation insulating structure including a flexible base sheet, insulating material secured to said base sheet and having an outer surface, open ended grooved portions in said surface comprising a first series of parallel spaced grooved portions and a second series of parallel spaced grooved portions extending perpendicular to the grooved portions of said first series and intersecting the same, fastening straps extending through each of said first and second series of grooved portions, an means securing the ends of said straps under tension.
Claim 2
Dependent Claim
90 words
A heat or cold and sound and condensation insulating structure including a flexible base sheet, insulating material secured to said base sheet and having an outer surface, open ended grooved portions in said surface comprising a first series of parallel spaced grooved portions and a second series of parallel spaced grooved portions extending perpendicular to the grooved portions of said first series and intersecting the same, fastening straps extending through each of said first and second series of grooved portions, an means securing the ends of said straps under tension.
Claim 3
Dependent Claim
31 words
The combination as set forth in claim 1 in which said means includes a rail member having a pocket portion, and a strap clamping element releasably secured in said pocket portion.
Claim 4
Dependent Claim
114 words
The combination as set forth in claim 1 in which said strap clamping element is wire material bent in the form of a U-shape to define the parallel extending leg portions of said U-shape and the ends of said wire are extended and bent to provide a pair of open ended leg portions which extend parallel to each other and also parallel to the first-mentioned leg portions with a corresponding one of said pair of leg portions being spaced from a corresponding adjacent one of the first-mentioned leg portions a distance substantially equal to the thickness of one of said fastening straps to allow such strap to be wrapped around said adjacent leg portions.
Claim 5
Dependent Claim
90 words
The combination as set forth in claim 3 including a building structure having a generally planar surface, said rail member and said insulating structure being mounted on said planar surface, said pocket portion having an internal ledge portion which is spaced from said planar surface a distance substantially less than the spacing between said planar surface and the bottom of said grooved portions, and said ledge portion being contacted by said one of said leg portions which is spaced away from those leg portions around which the strap is wound.
Claim 6
Dependent Claim
23 words
The combination as set forth in claim 4 in which said planar surface is the roof of a mobile home or the like.
