摘要:
A roof product has a thermal heat storage layer, a vent layer with channels for transferring excess heat through a length of the roof product, and a flame retardant to suppress fire through the vent layer. These three materials form a unitary structure. The roof product may have a radiant layer, the thermal heat storage layer and the vent layer to form the unitary structure. The roof products are assembled in an abutting configuration on the roof of a building. The vent layer vents excess heat from an eave of the roof up to a ridge of the roof and out to atmosphere. The roof products manage thermal energy in the roof by storing thermal heat with the unitary roof product during a heating cycle; venting excess heat through the unitary product; and releasing the stored thermal heat from the unitary product into or out of the building during a cooling cycle.

Roofing granule mixtures include multiple classes of algae-resistant granules, with each class of algae-resistant granules including at least one algaecide. One class of granules provides immediate algae resistance, while release of algaecide from other granules is delayed.

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.

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.

Photovoltaic wiring arrays and photovoltaic wiring systems suitable for use in rooftop photovoltaic power generation systems are provided. Accordingly, one aspect of the invention provides a photovoltaic roofing wiring array for use with a plurality of photovoltaic roofing elements, the photovoltaic roofing wiring system including: a positive parallel wiring run comprising a main line and one or more connection branches pendant from the main line, each connection branch being terminated in a positive connector; and a negative parallel wiring run comprising a main line and one or more connection branches pendant from the main line, each connection branch being terminated in a negative connector. In some embodiments of the invention, the photovoltaic roofing wiring arrays are substantially prefabricated.
摘要:
A shingle having butt and tab portions is provided, wherein the tab portions are exposed when applied to a roof, and wherein active photovoltaic element(s) appear on portions only of the tab portions of the shingles, wherein adjacent zones of the tab portions of the shingles to which the photovoltaic element(s) are applied are free of active photovoltaic elements. The shingles are applied to a roof or a major portion of a roof, laid up in courses so that exposed tab portions of next-overlying courses cover unexposed butt portions of next-underlying courses, leaving photovoltaic elements exposed. In an array of shingles on a roof, the photovoltaic elements are distributed substantially uniformally. The surface ornamentation of the exposed surfaces of the photovoltaic elements may be either complementary to the exposed surfaces of the shingles not having photovoltaic elements thereon, or may blend with such zones not having photovoltaic elements thereon.

A hip, ridge or rake shingle is provided, in which a pair of substantially rigid panel portions are connected by a hinge portion, and wherein the shingle is pre-assembled, but can conform to a variety of different angles to accommodate different angular relationships between surfaces of a hip, ridge or rake of a roof. The substantially rigid panel portions are connected by a hinge and may or may not have a reinforcement member, and all of the panels, hinges and reinforcement members are of synthetic thermoplastic polymeric construction and are welded together by ultrasonic or vibratory welding techniques.
