Abstract: The present disclosure relates generally to roofing elements and methods for making them. In one embodiment, the disclosure provides a roofing element in the form of a roofing shingle that includes a body of a foamed cured cross-linked polymer, the body having a top surface and a bottom surface, the body extending substantially in a plane and having a thickness in the range of 0.5 mm to 35 mm; and a layer of weather-resistant roofing granules disposed on and adhered at the top surface of roofing element. The roofing element can be made by providing a body of wet foamed curable composition, and allowing the curable composition to cure to provide the body of foamed cured cross-linked polymer.

Abstract: The present disclosure relates generally to polyurethane matrix composite materials, for example, suitable for making an exterior cladding product for houses and other buildings. The present disclosure relates more particularly to a polymer matrix composite material including a polyurethane matrix and an inorganic filler in a range from 45% to 85% by weight of the composite material. The inorganic filler includes a first substance from the group consisting of calcium carbonate, sand, talc, kaolin clay, dolomite, feldspar and mica and any mixture thereof, and fly ash, and/or an iron oxide in a range from 0.5% to 7% by weight of the inorganic filler.

Abstract: Provided are photo-curable foam-forming compositions, methods of making and using them, and a dispenser for injecting the foam-forming composition for the insulation of buildings. In one aspect, the present disclosure provides for a method of insulating a surface, such as that of a building cavity with an insulating foam, the method comprising: irradiating a foam-forming composition with light, the foam-forming composition comprising: a polymerizable component (e.g., based on epoxy or acrylate); an effective amount of a photoinitiator; and a blowing agent; and injecting the irradiated foam-forming composition adjacent the surface.

Abstract: The present disclosure relates generally to methods, devices and systems for insulation, e.g., of cavities associated with walls, ceilings, floors and other building structures, with foam insulation. In one aspect, the disclosure provides a method for providing a cavity of a building with an expanded foam insulation. The method includes dispensing an amount of an expanding foam insulation into the cavity, the expanding foam insulation being dispensable and expandable to provide the expanded foam insulation material, the expanding foam insulation material formed from a premix comprising at least one polyol, at least one polyisocyanate, a blowing agent, and an encapsulated catalyst, the encapsulated catalyst comprising a plurality of catalyst capsules, each comprising an amount of catalyst and a capsule shell encapsulating the catalyst, wherein the dispensing is performed to apply a force to the encapsulated catalyst sufficient to break capsules and release catalyst, the released catalyst initiating reaction between the at least one polyol and the at least one isocyanate; and then allowing the dispensed amount of expanding foam insulation to substantially finish expanding after it is dispensed in the cavity, thereby forming the expanded foam insulation in the cavity.

Abstract: Provided are roofing membranes comprising pressure-sensitive adhesives particularly adapted for use at cold temperature, and methods for using same. In one aspect, the disclosure provides a roofing membrane comprising: a bituminous sheet having a lower bituminous surface and an upper bituminous surface; and a non-bituminous cold-temperature pressure-sensitive adhesive disposed on the lower bituminous surface, the upper bituminous surface, or both, wherein the cold-temperature pressure-sensitive adhesive has an average adhesion of at least 10 lbs/ft (146 N/m) at 2° C. as measured by a two hour T-peel test.
