Abstract
Abstract An aesthetic roofing panel or other aesthetic panel and method of producing it, comprising a substantially rigid panel shaped foam body having an upper surface which aesthetically smiluates roofing configuration; and a weather resistant sheet of a shape conforming to said upper surface; said weather resistant sheet bonded to said upper surface of said body; a plurality of said roofing panels having edge portions adapted to overlap adjacent edges of adjacent ones of said panels to shed water thereover; connecting respective cooperable interlocking means of each panel and an interlocking strip on a roof structure, respectively, for readily and securely fixing said panels on said roof structure; the disclosure also including a novel method for producing said roofing panels, comprising the forming of a thin weather resistant sheet of material into an aesthetic roof or other surface simulating configuration and casting a substantially rigid foam body under pressure contiguous with and bonded to said formed weather-resistant sheet; further, the method includes the provision of an interlocking means on said foam body and the securing of an interlocking strip on a roof or other structure and the installation of said panels on said roof or other structure by interlocking said interlocking means with said panel or a plurality thereof.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
343 words
A roofing panel and associated connecting means comprising in combination: a substantially rigid plastic foam body having normally upper and lower surfaces; said upper surface having a thin, weather resistant sheet bonded thereon having a roof surface simulating configuration; said lower surface being substantially flat and adapted to conform generally to roof sheathing or the like; said panel having upper and lower longitudinal edges and first and second normally inclined edges disposed at opposite ends of said panel; said panel having said first inclined edge provided with a first ledge portion adapted to extend above and overlap the second inclined edge of an adjacent panel; the lower edge of said panel provided with a second ledge portion adapted to overlap and cover a respective upper edge of an adjacent panel; said panel at said first inclined edge and at said lower edge having a flange receiving groove, said groove being spaced from said lower surface of said panel so as to coincide with the bottoms of said first and second ledges, the thickness of said second inclined edge of an adjacent panel, and with the thickness of the upper edge of an adjacent panel; and means for joining a plurality of said panels comprising a plurality of identically shaped elongated connecting means, each having a base portion adapted to be fixed contiguous to roof sheathing or the like upon which said lower surface of said panels are disposed, and a web portion extending upwardly from said base portion, and opposed flanges extending outwardly from the said upper part of said web portion; first ones of said connecting means having one of said opposed flanges engaged in said flange receiving grooves in the first inclined edge of each panel, the other of said opposed flanges overlying said second inclined edge of an adjacent panel; second ones of said connecting means having one of said opposed flanges overlying an upper edge of each panel, the other one of said flanges being engaged in said flange receiving groove at said second ledge of an adjacent panel.
Claim 2
Dependent Claim
