  • System, method and apparatus for thermal energy management in a roof
    Patent number: 9840846
    Abstract: 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.

  • MULTILAYER ARTICLE WITH VARIEGATED APPEARANCE
    Publication number: 20170138047
    Abstract: 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.
