摘要:
A method of forming a roofing product can include providing a ceramic base material having an open structure. The method can also include filling the open structure of the ceramic base material with a bituminous material, wherein the bituminous material has no greater than approximately 5 weight % of abrasive particles. The method can further include applying a recycled roofing material adjacent to the ceramic base material after filling the open structure of the ceramic base material with the bituminous material. In a particular embodiment, an open structure of the ceramic base material is filled with a bituminous material that has no greater than approximately 2 weight % of abrasive particles or 0.1 weight % metal content. The recycled roofing material can be applied along one or both sides of the ceramic base material. The bituminous material may have a characteristic particle size that is smaller than a characteristic particle size of the recycled roofing material. In another embodiment, the roofing product having the recycled roofing material can have tear strength characteristics as compared to a different roofing product having a substantially the same construction but having abrasive particles embedded within the ceramic base material.

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.

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.

The present invention relates particularly to photovoltaic roofing systems in which photovoltaic elements are integrated on a roof deck with conventional roofing materials. In one aspect, a photovoltaic roofing system includes a two-part tee element disposed on a roof deck, the two-part tee element comprising a base piece including a central portion; two opposed horizontally-extending first and second flanges extending from the central portion, and a top piece attachment feature formed in the central portion, and a top piece including a base piece attachment feature mated with the top piece attachment feature of the base piece; and a vertically extending portion extending from the base piece attachment feature. A first photovoltaic element can be disposed on the roof adjacent the base piece with its edge disposed on the horizontally-extending first flange of the base piece of the two-part tee element.

Synthetic polymer based roofing elements of the shingle or tile type are provided whereby adjacent roofing elements have projecting tabs or nibs that are adapted to engage against side edges of adjacent shingles or tiles when laid up in courses on a roof, and wherein there are relatively flexible stress relief zones in the shingle or tile adjacent the tab or nib projections, adapted to be deformed within their elastic limit when the shingles or tiles are subjected to stresses due to thermal expansion and contraction, with the stress relief zones also being adapted to return to their original non-deformed condition when such thermal expansion and contraction forces are relieved.

摘要:
Roofing elements of the shingle, tile or panel types are applied for mounting onto a roof of a building, as well as a roof covering comprised of such elements. The roofing elements include at least one heat-sensitive weatherproof, protective layer for protecting the building from weather-related intrusions. The roofing elements have one or more continuous venting channels disposed below the heat-sensitive weatherproof, protective layers to form one or more airflow channels beneath the protective layers, with the airflow channels disposed between a lower roof deck of a building and upper heat-sensitive, weatherproof, protective layers of the roofing elements in the installed condition on a roof.
