International Classification:

B29C 49/04

US Classification:

264515, 264516, 264157, 264267, 264 466

Abstract:

A process of simultaneously molding either a plurality of composite shingles or double walled shingles or other substantially planar exterior building products is 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 according to the process. Ventilation and/or insulation can be provided to a hollow interior between spaced apart walls of a double walled shingle.

Abstract:

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.

International Classification:

B32B 7/02

US Classification:

428212

Abstract:

An exterior surface covering has a colored outer layer that transmits infrared radiation and an inner layer with a thermochromic pigment that absorbs heat at low temperature and reflects at high temperatures. The outer layer conceals the color change of the thermochromic pigment.

International Classification:

E04D 13/00
E04D 13/10

US Classification:

52 26, 527481

Abstract:

A roof structure and a method of installing a snow guard on the base of a roof is provided, wherein the roof structure includes a plurality of synthetic shingles of thermoplastic materials, and where a snow guard is provided having an outwardly projecting snow-engaging platform and an oppositely provided hook at an upper end, wherein the hook is adapted to engage over and upper edge of a butt portion of one or more shingles in an underlying course of shingles, and wherein a tab portion of a shingle in a next-overlying course of shingles is disposed over the upper end of the snow guard, substantially covering its base, and wherein the snow-engaging platform is adapted to receive snow and ice that may slide down the roof, to intercept the same or break the snow or ice up into small harmless particles. The synthetic shingles of thermoplastic materials allow for the upward bending of the overlying tab portions of shingles a substantial amount within their elastic limit, to permit insertion of snow guards under tab portions of overlying shingles, where such tab portions of overlying shingles are already-installed on a roof, followed by a relaxation of the upwardly bent tab portions of shingles back to a flattened condition overlying the butt portions of shingles in an underlying course of shingles, and overlying the base of the snow guard between the platform and hook, due to the inherent memory of the original flattened shape of the shingles that have their tab portions flexibly upwardly bent.
