Abstract
A curved roofing tile which is formed of strong materials so that it may be fabricated in an extra-width configuration. Strengthening ridges and connector ridges are compression molded so the roofing tile forms a one-piece unit. To help the ecology, recycled materials such as rubbers and plastics are combined into a novel formula of high strength, Class A flame retardancy and economy of manufacture.
Claims5
A roofing tile (10) having top and bottom edges (15,16), a left side edge (11) and a right side edge (12),
- at least two peaks (21,22) running from said top edge (15) to said bottom edge (16),
- said tile having a central valley portion (31) and right and left partial valley portions (32,33),
- wherein said tile left side edge (11) has a pair of connecting ridges (51,52) formed thereon for providing a joining function,
- wherein said tile right side edge (12) has a pair of connecting ridges (53,54) formed on a bottom portion thereof,
- wherein strengthening ridges (41,42) are formed at a top portion (15) of said tile,
- wherein said tile (10) includes further strengthening ridges (43,44) at a central portion thereof and further strengthening ridges (45,46) at a lower edge (16) thereof.
3 more elements
A method of forming a curved roofing tile of high strength and economical manufacture comprising the steps of:
- A) mixing a compound comprising the materials EDPM, SBR, EVA and ULDPE, ATH and zinc oxide, and HDPE and a coloring agent,
- B) extruding said compound into a mass of a particular volume and weight,
- C) compression molding said compound into a one-piece roofing tile (10) having lateral connecting ridges (51-54) and strengthening ridges (41-46) running substantially across the width of said roofing tile.
