A convertible floor panel assembly incorporates a metal wire mesh subfloor and a polymer deck overlying the wire mesh subfloor. A plurality of alignment heads project from an underside of the polymer deck, and are designed to extend through respective mesh openings defined by the wire mesh subfloor. A plurality of panel retainers engage respective alignment heads, and are adapted for removably attaching the wire mesh subfloor and the polymer deck together. The floor panel assembly is thereby convertible between a substantially open-surface sound permeable safety structure and a continuous solid-surface structure for increased floor load capacity.

Disclosed is an improved facer mat for use as a cover sheet for gypsum board. Also disclosed are gypsum boards containing such mat facers on one or both major surfaces of the board (face and back sides when installed), a method of manufacturing such board, and a method of making the mat. The mat can comprise glass, thermoplastic, and/or thermoset fiber. In preferred embodiments, binder is included with the fiber. The mat has outer and inner surfaces. The mat comprises a first region adjacent to the outer surface defined along a horizontal plane of the mat, the first region having a first substantial thickness, and a second region adjacent to the inner surface defined along a horizontal plane of the mat, the second region having a second substantial thickness. The first region has (a) more hydrophilicity than the second region, (b) more wettability than the second region, and/or (c) less density than the second region.

Embodiments of the invention provide composite roofing strips that may be attached to a roofing membrane for aesthetic and/or functional purposes and method of attaching the same. According to one embodiment, a composite roofing strip may include a longitudinally extending body having a base and a lateral member extending from the base, and may also include an insert extending partially or fully along the body and coupled therewith. The insert may be formable so as to allow the composite roofing strip to be adjusted to have a desired profile and to maintain the desired profile of the composite roofing strip post adjustment.

A roof system and related methods for installing the roof system. The roof system includes a roof diaphragm including a nail board and an insulating panel connected to the nail board, wherein the insulating panel is adapted to be positioned between the nail board and a roof frame so that the insulating panel engages the roof frame. In several exemplary embodiments, the nail board comprises one or both of: oriented strand board (OSB) and plywood. In several exemplary embodiments, the insulating panel comprises one or both of: a closed-cell rigid polyisocyanurate (polyiso) foam core and a polystyrene foam core. In several exemplary embodiments, the roof system further includes a plurality of nail board fasteners connecting the roof diaphragm to the roof frame, the nail board fasteners each extending through the nail board, through the insulating panel, and into the roof frame to a depth.

A weather resistive barrier (WRB) for the exterior protection of building substrates can have a water vapor permeability that decreases with increasing temperature. In an embodiment, the WRB includes a coating comprising a LCST polymer, and may further include a second polymer. The WRB can be part of a building assembly, part of a sheet, or a sheet itself, the sheet having an air permeability of less than 0.02 L/(s m.sup.2) at a pressure of 75 Pa. Furthermore a liquid coating composition can include a LCST polymer and a second polymer, wherein the liquid coating composition can be adapted that a solid coating formed by the liquid coating composition has an air permeability of less than 0.02 L/(s m.sup.2) at a pressure of 75 Pa and a water vapor permeability that decreases with increasing temperature.

A building panel is provided. The building panel includes an exterior wall portion, an interior wall portion, a pair of opposing sidewalls, a first end portion and an opposite second end portion. The pair of opposing sidewalls spacing apart the interior wall portion from the exterior wall portion to define a cavity therebetween. The exterior wall portion, the interior wall portion and the pair of opposing sidewalls are arcuate in shape to define the building panel. The first end portion has a slip lock slot extending between the pair of opposing sidewalls. The second end portion has a slip lock tab member extending between the pair of opposing sidewalls. The slip lock slot of the building panel is configured to receive the slip lock tab member of a second building panel to adjoin the first and second building panels in a continuous fashion.

The present invention relates to a novel process for the production of novel fiber-reinforced profile materials comprising a rigid foam core, in particular a PMI foam core. In particular, the present invention relates to a novel process which can be carried out in two variants, a short Pul-press process and a Pul-shape process. One step here produces a fiber-reinforced profile material and simultaneously inserts the rigid foam core into same. The same step moreover ensures very good binding of the rigid foam core to the fiber-reinforced profile material.

The roof system includes a roof diaphragm including a nail board and an insulating panel connected to the nail board, wherein the insulating panel is adapted to be positioned between the nail board and a roof frame so that the insulating panel engages the roof frame. In several exemplary embodiments, the nail board comprises one or both of: oriented strand board (OSB) and plywood. In several exemplary embodiments, the insulating panel comprises one or both of: a closed-cell rigid polyisocyanurate (polyiso) foam core and a polystyrene foam core. In several exemplary embodiments, the roof system further includes a plurality of nail board fasteners connecting the roof diaphragm to the roof frame, the nail board fasteners each extending through the nail board, through the insulating panel, and into the roof frame to a depth.

A fire resistant building panel comprising: a first major face; a second major face; and a fire resistant body comprising a binder, at least one additive, and at least one fiber material, wherein the binder comprises a calcareous material and a siliceous material; and wherein the fire resistant body is disposed between the first major face and the second major face. The fire resistant body provides a fire rating of at least 45 minutes as tested in accordance with Australian Standard AS1530.4-2005.

The present disclosure provides for a subfloor panel comprising a lignocellulosic material suitable for use as a subfloor and an integrated vapor retarder coextensive to at least one surface of the lignocellulosic material, wherein the lignocellulosic material comprises a first resin and the vapor retarder comprises a second resin. Further provided herein is a floor assembly comprising one or more subfloor panels as disclosed herein and a flooring material.
