Abstract: The retention of roofing granules on bituminous roofing products is enhanced by providing an adherent material in the interstices between the exterior surface of the roofing granules and the exposed upper surface of the base sheet.

Abstract: Time-release algae-resistant roofing granules have a base particle including an algaecide and an outer coating layer including another algaecide. The at least two algaecides are released over different predetermined periods. The outer layer protects the base particle from exposure to the environment for a predetermined period, then fails catastrophically so that the interior algaecide can be released.

Abstract: An apparatus for making a shingle, together with the shingle made thereby, is provided, in which one or more thermoplastic materials are extruded or co-extruded to form an extrudate, with the extrudate being cut into a preliminary shingle shape, which is allowed to dissipate heat, and then is delivered to a compression mold, wherein the preliminary shingle shape is compression molded to substantially its final dimensions and is then discharged from the mold and allowed to cool.

Abstract: 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.

Abstract: A co-extrusion process enhances the durability of the ultimate product over previous systems which use relatively fragile paint coatings to limit heat absorption. By providing near-IR transmissive and reflective pigments within the co-extruded polymers, a highly durable finished product is obtained. The co-extruded layers are disclosed for use in fence and deck applications, but will also find application in a wide variety of building product applications, both exterior and interior.

Abstract: A synthetic roofing shingle or tile is provided, in which a core material is formed, of generally less expensive material, and with a skin material provided, disposed on a plurality of surfaces of the shingle or tile, with the skin material being generally of greater expense and having desirable weather-withstanding qualities.

Abstract: A co-extruded structural member is disclosed having first and second co-extruded layers. The first co-extruded substrate layer comprises a structural preform and is substantially reflective of near-infrared (near-IR) radiation. A co-extruded cap layer is substantially transparent to near-IR radiation. The cap layer can be provided in aesthetically pleasing dark colors, while heat absorption is minimized due to the reflective properties of the near-IR reflective substrate layer.
