ABSTRACT:
Roofing systems are herein disclosed which lend themselves to simplified installation techniques and provide enhanced energy conservation over conventional roofing systems of comparable appearance. The system of this invention is based, in substantial part, upon the use of a large (typically 4'.times.8') panel of cellular structural foam as a replacement for ceramic and/or cast concrete roofing tiles ("Barrel" and "Bermuda" style tiles). In the preferred embodiments of this invention, a closed cell structural formed panel is molded or cut to simulate an array of roofing tiles. The simulated foam tile panel is further provided with a refractory (fireproofing) finish, such as stucco, or its equivalent. A finish coating is, thereafter, applied to the refractory coating to enhance water repellency and, thus, serve to further weatherproof the roofing panel. The finishing coating can be applied prior to or subsequent to installation of the foam tile panels. In one of the preferred embodiments of this invention the foam tile panel is laminated to a 4'.times.8' sheet of plywood or an "OSB" board; or, alternatively, internally structurally enforced. A reinforcing mesh is also preferably provided on the exposed surface of the panel and bonded thereto upon application of the refractory coating or finish. Structural inserts integral with the foam tile not only enhance its physical integrity and strength but also provide a means for attachment of the foam tile panel to the roof trusses.
