摘要:
A variegated capstock for covering a substrate for a building product has polymeric streaks in a non-clear, non-opaque matrix. Rapid cooling of the matrix minimizes formation of crystallites, such that the polymeric streaks become visible through a surface of the non-opaque matrix. The streaks are visible by having a color or an index of refraction different from that of the matrix. The matrix is in one or more layers, and the polymeric streaks are in the layers. The substrate is visible through the non-clear, non-opaque matrix and can appear partially obscured by the non-clear, non-opaque matrix.

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.
