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.

摘要:
A roofing granule can include a base particle having a base material and a layer covering the base particle of the roofing granule. The layer can has a first material and a second material that includes a metal carbonate, wherein the first and second materials include a same metal element, and the base material is different from the first material. In a process of forming the roofing granule, the layer can have pores. The process can include infiltrating a fluid into the pores of the layer while the base particle is present and adjacent to the layer, wherein the fluid includes a carbonate. The process can further include reacting the carbonate with a metal compound within the layer to form a metal carbonate within the layer. The roofing granules can be used in roofing products.
摘要:
Roofing granules are prepared by coating granule cores with a coating material including composite nanoparticles and curing the coating layer to dissolve the aggregate binder and disperse the nanoparticles in the coating.

A roofing product can include a base material and a first coating including a bituminous material. In one embodiment, the first coating can include recycled roofing material adjacent to the base material. The recycled roofing material has a first recycled roofing content of less than 40 weight %. In another embodiment, the roofing product can include a base material and a first coating including a bituminous material. The first coating is adjacent to the base material. The roofing product can also include particles along a first exposed surface of the roofing product, wherein the particles include recycled roofing material particles. Methods of forming such roofing products are also disclosed.
摘要:
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:
Algae-resistant roofing granules include a mineral core and an exterior coating including clay, colloidal silica, phosphate, a metal oxide, and a photocatalytic particulate having an average size under 100 nm. By varying the proportions of the components to the binder for the exterior coating, improved control of the pot life of the coating composition can be achieved, and the binder can be formulated to accommodate different manufacturing conditions.
摘要:
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.
