Described herein is an stain and sag resistant acoustic building panel comprising a porous body formed from building material and latex binder, wherein the building material may include fibers and filler and at one of the building materials has been pre-treated with a charge-modifying component, thereby enhancing the sag-resistance of the building panel.

The present disclosure relates generally to an insulation-retaining sheet, e.g., for blown-in insulation, that includes an integral vapor-retarding membrane. In one aspect, the disclosure provides an insulation-retaining sheet including a sheet of mesh having an air permeability of at least 200 cfm per square foot; and one or more strips of vapor-retarding membrane, the one or more strips of vapor-retarding membrane being laminated to the sheet of mesh, the first side edge each of the strips of vapor-retarding membrane extending to the first side edge of the sheet of mesh, the second side edge each of the strips of vapor-retarding membrane extending to the second side edge of the sheet of mesh, wherein the insulation-retaining sheet has a plurality of open zones extending laterally from the first side edge of the sheet of mesh to the second side edge of the sheet of mesh in which no vapor-retarding membrane is laminated to the mesh.

An enclosure for use as a walk-in freezer or refrigerator includes a first panel and a second panel connected to the first panel. Each of the first and second panels includes a body having a frame coupled to the body. The frame includes a beam of a first material and a jacket of a second material at least partially enclosing the beam. An interior edge of the frame is adjacent to the body. An exterior edge is defined by the jacket and defines a joint member. The joint member of the first panel defines a groove, and the joint member of the second panel defines a protrusion adapted to engage the groove of the joint member of the first panel. At least one joint member includes a deformable portion that compresses when the joint member of the first panel engages with the joint member of the second panel.

A safety component for a skating rink. The safety component comprises a body portion connectable to a transparent barrier located above dasher boards of the skating rink, wherein upon impact the body portion is capable of at least partially absorbing impact forces. The safety component further comprises a curved rink-facing surface that provides a substantially convex curved surface facing the skating rink. The curved rink-facing surface has a radius of curvature suitable for redirecting the impact forces away from the convex curved surface.

Disclosed herein are modular enclosures for temperature-sensitive components that include a modular wall section some of which include a vertical support panel, a vertical strut channel connected to the vertical support panel, and a temperature-sensitive component connected to the vertical strut channel.

A reinforced water-resistant board includes a cover board with a reinforced water-resistant membrane applied to a surface of the cover board. The reinforced water-resistant membrane includes a primer layer, a reinforced membrane, a traffic coat, and a sealing layer. The primer layer is applied over the surface of the cover board. The reinforced membrane includes fleece soaked in a liquid resin and is applied over the primer layer. The traffic coat is boned to the reinforced member. The sealing layer is applied over the traffic coat.

A building component has first and second parallel and spaced apart edges, a first panel portion and first and second members. The first and second members are located on the same side of the first panel portion. The members extend along the first and second edges. A second panel portion is demountably connected to the first panel portion in a face to face relationship. This creates a plurality of cavities within the building component. A plurality of holes is formed in the component to enable passage of services such as electricity, gas and water through the component.

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.

Foam wall structures and methods for making them are described. The wall structures include a frame, a foam panel overlying a front surface of the frame, and a polyurethane foam layer disposed in a cavity of the wall structure. The polyurethane foam layer has a density, as determined by ASTM D1622-14, of at least 44 kg/m.sup.3(2.75 lb/ft.sup.3) and exhibits ASTM E84-16 Class A flame spread and smoke development characteristics. The polyurethane foam layer is the cured reaction product of a polyurethane foam-forming composition that includes a polyisocyanate, an aromatic polyester polyol having a functionality of greater than 2.5 and an OH number of at least 300 mg KOH/g, which is present in an amount of at least 50% by weight, based on the total weight of the polyurethane foam-forming composition less the weight of the polyisocyanate, a catalyst, and a blowing agent composition. The blowing agent composition includes water and a hydrofluoroolefin.

An exterior wall cladding system for application to an exterior wall surface comprises a sealed and laminated waterproof wrap applied to the exterior wall surface, a fully-sealed insulating panel without a drainage plane disposed over the sealed and laminated waterproof wrap. The cladding system and method provide a waterproof wall structure for a multi-layer stucco coating applied over the insulating panel. Sealing materials are applied to all openings through and edges of the wall structure.
