摘要:
A laminated roofing product can include a first sheet including a first coating that is substantially free of recycled roofing material, and a second sheet adjacent to the first sheet. The second sheet can include a second coating having a second sheet recycled roofing material. In another embodiment, the laminated roofing product can include a first sheet including a first sheet recycled roofing material, and a second sheet adjacent to the first sheet. The second sheet can include a second sheet recycled roofing material, wherein the second sheet has a higher recycled roofing content as compared to the first sheet. In another embodiment, a method of forming a laminated roofing product includes laminating a first sheet and a second sheet together. The second sheet has a higher recycled roofing content as compared to the first sheet.

A roof covering material is provided, as well as its method of manufacture, wherein a substrate, preferably of a fibrous material is provided, with a bituminous material, preferably asphalt coating, on opposite surfaces thereof, with granules being applied to an upper surface thereof and at least partially embedded in the bituminous material, and with a discontinuous top layer applied to the granule/bituminous material. The discontinuous top layer is preferably a polymeric material, and openings are provided therein, for passage of fluids therethrough, to avoid moisture, volatiles, and other fluid materials from being trapped beneath the top layer. Various techniques for application of the various materials, and for chemical treatment, are likewise provided.
摘要:
A roll roofing material is provided in the form of a cylindrical roll that may or may not have an exterior covering thereon, and with transverse members being provided, carried by the cylindrical roll, and which protrude generally outwardly of an exterior cylindrical surface of the roll. The transverse members inhibit rolling of the roll roofing either off a pitched roof. One or more inserts may be provided in a hollow core of the roll, and connectors may attach a strap to these inserts for transporting the same from ground to a rooftop, or otherwise. Protective covers may be provided at opposite ends of the roll roofing, and the protective covers may comprise the transverse members, as may be desired.
摘要:
The present invention relates more particularly to roofing products for use with photovoltaic elements, and to photovoltaic systems that include one or more photovoltaic elements joined to a roofing substrate. In one aspect, the invention provides a roofing product including: a bituminous roofing substrate having a top surface; and roofing granules embedded in the top surface of the roofing substrate, wherein in at least one over-pressed zone of the roofing product, the roofing granules are embedded so that (a) the over-pressed zone exhibits a 0.20 gram loss or less in a rub test as described in ASTM D-4977; or (b) in the over-pressed zone the average granule embed volume fraction is at least 0.5; or (c) in the over-pressed zone, the average distance between the top of the roofing granules and the top surface of the bituminous roofing substrate is 1.0 mm or less.

摘要:
A plurality of hip, ridge or rake shingles, and the shingles produced thereby and stacks and packages of such shingles are provided.An adhesive impregnated mat is moved longitudinally, and granules are provided onto adhesive, in predetermined bands. An overlay band of adhesive, continuous or discontinuous is provided, with granules thereon, increasing the thickness of the shingle material being made, in predetermined bands, relative to the remainder of the shingle material. The shingle material is slit longitudinally, and one portion can be laminated to another portion, preferably creating a multiple-ply laminated shingle material with thickened overlay portions and optionally with shadow line portions. The material is then slit longitudinally, and cut transversely into a plurality of hip, ridge or rake shingles, which may be individually separated from each other, or which may comprise a plurality of connected together shingles. The shingles are then stacked and wrapped.

The present invention relates generally to the photovoltaic generation of electrical energy. The present invention relates more particularly to photovoltaic arrays for use in photovoltaically generating electrical energy. Aspects of the present invention provide a variety of photovoltaic roofing elements and systems that include, for example, interlocking geometries to provide for water handling and integration with conventional roofing materials; and wire management features that can protect wiring and associated electrical components from physical and/or environmental damage.
摘要:
A method of forming a roofing product can include providing a ceramic base material having an open structure, and filling the open structure of the ceramic base material with a bituminous material. In a particular embodiment, the bituminous material has no greater than approximately 5 weight % of abrasive particles or has a first particle size distribution. The method can further include applying a recycled roofing material. In an embodiment, the recycled roofing material is applied along a principal surface of the ceramic base material or adjacent to the ceramic base material. In a particular embodiment, the recycled roofing material has at least 2 weight % acid-insoluble solids or has a second particle size distribution that is narrower than the first particle size distribution.

The present invention relates generally to photovoltaic devices. The present invention relates more particularly to photovoltaic roofing products in which a photovoltaic element is joined to a roofing substrate. In one embodiment, the present invention provides a photovoltaic roofing element comprising: an encapsulated photovoltaic element having a top surface and a bottom surface, a top layer material at its top surface and a bottom layer material at its bottom surface; a roofing substrate having a top surface; and a tie layer system disposed between the encapsulated photovoltaic element and the roofing substrate and joining the bottom surface of the encapsulated photovoltaic element to the top surface of the roofing substrate.
