Building panels, assemblies of building panels, and associated methods are provided. A building panel includes a structural core, such as a set gypsum core, at least one filamentous scrim associated with the core, and a nonwoven mat facer.

A building system includes a plurality of shingles mounted adjacent one another relative to a building surface. Each of the plurality of shingles has a core formed from a compressed, shredded composite material, and each of the plurality of shingles includes a first end having a first thickness and a second end having a second thickness.

A construction board comprising a foam layer, an pressure-sensitive adhesive layer that is at least partially cured, and a release liner.

Exemplary systems and methods allow for enhanced energy performance of buildings, for example hybrid roof systems. The system may utilize a material having a porous water-retaining substrate and a high albedo coating. The high albedo coating may be disposed on the outer surface of the porous water-retaining substrate.

A blister resistant asphalt impregnating composition comprises asphalt, a linear styrene butadiene block copolymer, a radial styrene butadiene block copolymer, a reactive elastomeric polymer and a fire retardant.

A functional roof construction arrangement for a roof frame of a building, includes a plurality of functional roof modules being assembled together. Each of the functional roof modules includes a module housing and a roof functional unit which includes three different roof functional panel units selectively supported by the module housing at different levels thereof to provide different functions for the building. The roof functional panel units are selectively configured for selectively providing multiple functions of solar energy collection, thermal insulation, sound insulation, wireless network system, and the like.

Polyurethane foams having a NFPA 101 Class B rating (ASTM E-84) which pass the FM 4450 Calorimeter Test are produced by reacting: (a) an organic polyisocyanate, (b) at least one polyether polyol or polyester polyol with a nominal hydroxyl functionality of at least 2.0, (c) a blowing agent composition and (d) at least one halogen-free flame retardant. The blowing agent composition includes: (1) no more than 10% by weight, based on total weight of the foam-forming composition, of one or more hydrocarbons having an LEL less than 2% by volume in air, and/or (2) a hydrocarbon having an LEL greater than 2% by volume in air, and (3) up to 1% by weight, based on total weight of foam-forming composition, of water.
