摘要:
A fire resistant roofing material includes a core sheet and a sheet of conductive material having a thermal conductivity greater than about 25 W/m-K. The sheet of conductive material is coextensively bonded with the core sheet, and coated with a polymer-modified bituminous material having fire-resistant properties.

The present invention relates generally to roofing products. 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 embodiment, a roofing product includes a flexible roofing substrate having a top surface, the top surface having one or more granule-coated zones thereon capable of acting as a receptor zone or an exposure zone, each zone being adapted to receive one or more photovoltaic elements; and an adhesive suitable for securing photovoltaic elements to one or more of the granule-coated zones, the adhesive capable of forming a bond to the granules and the top surface of the flexible roofing substrate and to the bottom surface of the photovoltaic elements.
摘要:
A roofing product having at least two separate zones, with one of the zones having one or more certain functional characteristics such as flame retardancy, solar reflectivity, weather resistance, selected coloring, heat stabilization, algae resistance, and/or solar collection for electrical generation, and another of the zones not having such functional feature(s). The different zones can be present in core or capstock material. The product can be made by any of various processes, such as co-extrusion, forming, molding, coinjection, shot injection moldings, multiple step injection moldings and/lamination.

The present invention relates generally to the photovoltaic generation of electrical energy. The present invention relates more particularly to photovoltaic roofing products for use in photovoltaically generating electrical energy. One aspect of the invention is a photovoltaic roofing element comprising: a flexible roofing substrate; a photovoltaic element disposed on the flexible roofing substrate; and an electrical connector operatively coupled to the photovoltaic element, wherein the flexible roofing substrate has formed therein a recess shaped to at least partially receive the electrical connector.
摘要:
A process of forming a building product can include providing a first layer having a first material, and providing a second layer having a second material that different from the first material, wherein the second layer has pores. The process can further include infiltrating a fluid into the pores of the second layer while the first layer is present and adjacent to the second layer, wherein the fluid includes a carbonate. The process can still further include reacting the carbonate with a metal compound within the second layer to form a metal carbonate within the second layer. In another aspect, a building product can include a first layer having a first material, and a second layer having a second material and a third material that includes a metal carbonate. The first material can be different from the second material, and the second and third materials can include the same metal element.
摘要:
A roofing product and method includes coating a substrate with bitumen to yield a bitumen coated substrate having an exposure zone. First granules are adhered to the exposure zone to yield a first granule coating. The first granules have a solar reflectance greater than 35. An adhesive is adhered to at least a portion of the first granule coating. An open portion of the first granule coating that is free of the adhesive is maintained. An overlay of non-white second granules is adhered to the adhesive, such that the overlay of second granules and the adhesive provide a raised structure above a plane of the first granule coating.
摘要:
A shingle layer of shingle is provided having an increased thickness adhesive coating on at least a portion of its rear surface, with granules embedded therein, with the granules being of a size range that is larger than the fine particles normally applied to the rear surface of a shingle layer.

The present invention relates generally to roofing or siding products. The present invention relates more particularly to roofing or siding products for use with photovoltaic elements, and to photovoltaic systems that include one or more photovoltaic elements joined to a roofing or siding substrate. In one embodiment, a roofing product includes a rigid roofing or siding substrate having a top surface, the top surface having one or more receptor zones thereon, each receptor zone being adapted to receive one or more photovoltaic elements, each receptor zone having a different surfacing than the area of the top surface adjacent to it.
摘要:
A roof covering of shingles or tiles is provided, with each shingle or tile being relatively rigid, having relatively flexible stress relief nail zones, that may comprise variations in thickness relative to the remainder of the shingle or tile, or variations in materials, such as will allow for relative movement of the shingles or tiles due to temperature variations resulting in expansion or contraction, or due to other forces, such that the movement will be between the shingles or the tiles and the nails or other fasteners that are used to secure the shingles or tiles to a roof or other surface, and is preferably within the elastic limits of the fastening zones of the shingles or tiles.
摘要:
A process for making 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.
