Abstract: The insulation panel (26) includes a corrugated sheet (28) having a fibrous blanket of insulation (32) secured thereto and an end cap (41) secured to an upper portion of the corrugated sheet (28). The end cap (41) provides a means by which an upper portion of the panel (26) may be anchored to a vertical structural wall (11) to be insulated and a means by which a panel (26) in a next upper row may be supported. After installation, fastening means (43) between the end cap (41) and the corrugated sheet (28) is removed to allow the upper portion of the corrugated sheet (28) to float in the end cap (41) and compensate for thermal expansion and contraction. In another embodiment of the panel (26a), the fastening means (43a) between the end cap (41) and the corrugated sheet (28) is frangible and shears in two upon expansion and contraction of the corrugated sheet (28).

Abstract: This invention relates to a novel bitumen mixture and a high performance prefabricated waterproofing membrane useful for roofing which is obtained by impregnating different layers of reinforcing material with the bitumen mixture. More particularly, the invention relates to a novel bitumen mixture and a waterproofing membrane comprising a series of reinforcing layers including a polyester mat, a mat of fiberglass and a fiberglass net. Each reinforcing layer is impregnated with bitumen mixed with a thermoplastic polymer wherein the polymer is selected from the group consisting of an amorphous copolymer of ethylene/propylene, atactic polypropylene, polyisobutylene and styrene-butadiene-styrene block copolymer. The mixture has a ring and ball softening point of at least 105.degree. C. and preferably about 155.degree. C.
