ABSTRACT:
A pre-fabricated roofing and siding panel with simulated shingles or tiles has an exterior insulating layer composed of approximately 80% by volume hollow glass biosilicate beads suspended in a polyurethane foam. The exterior layer is bonded to a decking layer of a light honeycomb fiberglass sheet in a process where the decking layer is placed in the bottom of a mold and a mixture of the glass bubbles and a two component polyurethane foam is injected into the mold. To provide the panels strength and moisture integrity at their abutting edges, an improved dual interlocking construction is provided at the panel edges. An interlocking rib and groove are provided at the top and bottom edges of the decking layer to interlock the panel in a perpendicular plane, while a separate barrier ridge and groove are provided in the exterior layer to interlock the panel in the plane of the panel.
In a further aspect of the invention, nailess anchoring mechanisms for the panels include anchor plates molded into each panel and corresponding retaining brackets. Knurled retaining rods are used to anchor the panel to roof trusses or wall studs by forcing the knurled rod ends through opposing star fastener openings in the panel anchor plates and the retaining brackets when the retaining brackets are secured behind a structural member.
