Abstract
A prefabricated panel system which can be erected to form a watertight surface suitable for use as the roof or wall of a building is disclosed. Each panel of the system includes a structural portion having a flexible membrane covering, a foam center member, a corrugated metal panel extending beyond the foam center and the surface of the panel assembly, and elongated, flexible fastener halves disposed along each edge of the flexible membrane. The panels are assembled together in edge-to-edge relationship with the fastener halves engaged to provide a continuous waterproof membrane extending across the joint between adjacent panels. Interstitial regions defined by the junction of adjoining panels are sealed to complete the waterproof membrane. This seal is provided by a viscous adhesive sealing material which is caused to flow into the interstitial regions by compressive means.
