A building panel of the roofing or siding type is disclosed, as well as a building structure having such roofing or siding panels, in which the panels are comprised of two different types of building materials. The composite panel includes at least one layer of synthetic polymeric building material, having adhesively secured thereto at least one layer of asphalt based building material, with outer, upper surfaces of the panel, that would be weather-exposed in the installed condition on a building structure being comprised of the asphalt based building material, and with the synthetic polymeric layer(s) of polymeric building material being weather-protected in the installed condition on a building structure.

A roofing system comprises layered construction panels, each having a bottom structural layer to provide strength and support. A performance layer overlies the structural layer and provides performance or functional characteristics such as water proofing, water shedding and/or impact resistance. An upper or decorative layer overlies the performance layer and provides aesthetic features or a decorative appearance for the roofing system. The decorative layer of the construction panels can be removed without damaging or affecting the performance layer. The appearance of a roof can thereby be changed at will without requiring that the entire roofing system be removed and replaced.

Roofing panels with water shedding features may be installed on the roof of a house or other structure in lieu of or as an underlayment for traditional roofing materials. The water shedding features can be built into a base of the roofing panels, as part of a frame for the roofing panels, or formed as part of a waterproofing layer applied to the base of the roofing panels, or which can be configured as a roofing panel. The roofing panels also can be installed in overlapping courses along a roof with water shedding features applied thereto or incorporated along one or more peripheral edges. The water shedding features of adjacent roofing panels will collect and divert water away from the upper surfaces and/or away from headlap and/or sidelap joints defined between the roofing panels.

A roof system includes a roof deck, a weighted cover board disposed upwardly adjacent the roof deck and a plurality of fasteners coupling the weighted cover board to the roof deck.

A shingle assembly for installation on a roof structure is provided. The shingle assembly can include an insulative substrate, a surface sheet coupled to and extending across a substantial portion of the insulative substrate, and a hook-and-loop fastening system comprising a hook portion and a loop portion. The hook portion or the loop portion can be coupled to and extend along the insulative substrate adjacent the surface sheet. The other of the hook portion or the loop portion can be coupled to and extend along the surface sheet. The hook portion can be configured to mate with a loop portion of a first adjoining shingle assembly and the loop portion can be configured to mate with a hook portion of a second adjoining shingle assembly.

Self-adhering construction panels are methods for their manufacture and installation are provided. A construction panel includes a rigid panel core that includes gypsum or foam, and an adhesive or a precursor of an adhesive disposed on at least a portion of a first surface of the panel in an inactivated or unexposed form, wherein, upon activation or exposure of the adhesive or precursor, the adhesive is configured to secure the panel to a construction assembly.

A structural panel system formed from a substrate (such as cement board or paper) and structural metal studs (such as lightweight galvanized steel members), where the metal studs are embedded within an insulating core that is formed onto the substrate, where the metal studs are gapped from the inner surface of the substrate to prevent thermal energy from transferring from the substrate to the metal stud or vice versa. In addition, parallel assembly slots may be formed in the gap at the top and bottom ends of each panel assembly to provide connective access to the top and bottom ends of the metal studs for structural connection to the foundation at the bottom or other overhead structure at the top via connective components. The connective components include a bottom U-channel member and a top U-channel member that are configured to fit into the parallel assembly slots.

A polyisocyanurate foam insulation product includes polyisocyanurate foam produced from reacting an isocyanate and a polyol blend having a functionality of at least 2.2. The isocyanate and the polyol blend are reacted so that the polyisocyanurate foam has an isocyanate index equivalent with or greater than 300. The polyisocyanurate foam includes a fire retardant and includes between 0.02 and 0.45 weight percent of a zinc salt compound. The foam insulation board exhibits a flame spread of no greater than 25 and a smoke index of no greater than 50 when exposed to flame conditions in accordance with an ASTM E-84 test.

One subject of the present invention is a roofing device (1) comprising an area support (2) made up of panels of wood particles on which a vapor barrier first layer (3), an insulating second layer (4) and a third layer (5) that is impermeable to liquid water are laid. Said device (1) is one wherein the second layer (4) is a composite layer formed by the superposition of two distinct homogeneous elementary layers (6 and 6), namely a lower elementary layer (6) of wood fiber and an upper elementary layer (6) made up of a material that is at least partially bio-sourced, that has hygroscopic, antifungal and thermal-insulation properties and that has a low resistance to the diffusion of water vapor.
