摘要:
A shingle having butt and tab portions is provided, wherein the tab portions are exposed when applied to a roof, and wherein active photovoltaic element(s) appear on portions only of the tab portions of the shingles, wherein adjacent zones of the tab portions of the shingles to which the photovoltaic element(s) are applied are free of active photovoltaic elements. The shingles are applied to a roof or a major portion of a roof, laid up in courses so that exposed tab portions of next-overlying courses cover unexposed butt portions of next-underlying courses, leaving photovoltaic elements exposed. In an array of shingles on a roof, the photovoltaic elements are distributed substantially uniformally. The surface ornamentation of the exposed surfaces of the photovoltaic elements may be either complementary to the exposed surfaces of the shingles not having photovoltaic elements thereon, or may blend with such zones not having photovoltaic elements thereon.
摘要:
A process of simultaneously molding either a plurality of shingles or double walled shingles or other substantially planar exterior building products is provided, such that a blow moldable thermoplastic material is provided, of a composite parison that is then blow molded in a hollow mold, to produce novel shingles according to the process. Ventilation and/or insulation can be provided to a hollow interior between spaced apart walls of a double walled shingle.

A roofing membrane with high solar heat reflectance includes a bituminous base sheet, a tie-layer with a reinforcement material, and a solar heat-reflective upper layer.
摘要:
A simultaneously molded plurality of composite shingles or double walled shingles or other substantially planar exterior building products are provided, each being comprised of two or more layers of thermoplastic shingle material, such that a weatherable capstock material is provided outside a core material, in the form of a composite parison that is then blow molded in a hollow mold, to produce novel shingles. Ventilation and/or insulation can be provided to a hollow interior between spaced apart walls of a double walled shingle.

摘要:
An infrared-reflective material is applied directly to the bituminous surface of a roofing product to increase the solar heat reflectance of the product, even when deep-tone roofing granules are used to color the product. The infrared-reflective material can be applied as a powder or in a carrier fluid or film, and can be applied along with infrared-reflective roofing granules.
摘要:
An impact resistant shingle is provided, wherein the base mat is impregnated with an asphaltic material, with an asphaltic material on the upper surface of the shingle, and wherein another asphaltic material is disposed on the rear surface of the shingle, which other asphaltic material is softer with greater elongation than the asphaltic material used elsewhere in the shingle, such that crack resistance is afforded because energy from impact on the shingle is dissipated.

A roofing membrane with high solar heat reflectance includes a bituminous base sheet, a tie-layer with a reinforcement material, and a solar heat-reflective upper layer formed from a powder coating filled with a solar heat-reflective pigment.
摘要:
A synthetic roofing material for a roofing tile and a method of extruding a resinous polymeric precursor of an exterior polymeric sheet for one or more roofing tiles; and applying a weather durable coloring matter on a surface of the precursor, wherein the cooling matter comprises one or more pigment colors in a variegated surface coloration pattern, which simulates a distinctive coloration of a natural material. The precursor is impressed with surface topography features and a surface roughness that simulate the surface features of the natural material.
