20120085053 | LIGHTWEIGHT TILE WITH TAPERED SUPPORT - The present invention is directed to a lighweight the with a tapered support angle reverse, to the angle of the roof, a tile having uniform contact with the roof surface that does not require battens and can be walked on without the fear of breaking. This the can be fabricated in several materials including concrete, ceramic, porcelain or clay. By increasing the surface area of the underside of this tile with numerous cavities and ribs, the capability for dissipating heat is greatly increased. The lightweight tile has the option of incorporating a breathable, underlying cushioning/insulating With this system of interlocking and overlapping tiles, when the top tile overlaps the tile below the top tile cantilevers and lays flat on the tile below it, greatly reducing the vulnerability to stress fracture because of the reverse angle and supporting ribs structure of the tile. | 04-12-2012 |
