Abstract: A radon gas and/or moisture abatement system (or method) is located under the concrete slab of a building. The system (or method) includes a multilayered mat having a first layer, a second layer, and a third layer sandwiched between the first layer and the second layer. The first layer is non-permeable and faces the concrete slab. The third (or sandwiched) layer is an entangled net. The second layer is permeable layer. The layers are bonded together. Whereby radon gas and/or moisture are inhibited from entering the building by passing through and collecting in the multilayer product.

Abstract: A method for reducing sound transmission through a building wall includes placing a sound-deadening and/or thermally insulative drainage mat between an exterior wall cladding and an interior framing system. The sound-deadening and/or thermally insulative drainage mat including: a water or moisture permeable filter layer, an entangled net adjacent and joined to the filter layer, and a sound-deadening and/or thermally insulative layer adjacent and joined to the entangled net opposite the filter layer. The filter layer is placed adjacent the exterior wall cladding and the sound-deadening and/or thermally insulative layer is placed adjacent the framing system. The sound-deadening and/or thermally insulative layer is a fabric. Water or moisture within the wall is drained out of the wall via the entangled net and sound penetrating the exterior wall cladding is reduced or eliminated by the sound-deadening and/or thermally insulative layer.

Abstract: A drainage/ventilation product is placed in a budding structure. The product includes: a weather barrier membrane faces away from the building structure; a drainage structure affixed to and co-extensive with the weather barrier membrane; a moisture resistant layer affixed to and co-extensive with the drainage structure; an adhesive layer, the adhesive layer is a plurality of adhesive strips and/or scatter coated over and co-extensive with the moisture resistant layer, the adhesive is a pressure sensitive adhesive (PSA) and has a pull adhesion in a range of about 10-21 psi, and covers about 40-95% of a surface of the moisture resistant layer; and a release layer releasably covers and is co-extensive with the adhesive layer. Whereby the moisture/ventilation product is placed on the building structure without mechanical fasteners. A method is also disclosed.

Abstract: A wall (or roof) system includes: an exterior sheathing covers a frame, a plurality of spaced apart battens are affixed on the sheathing, and a siding in contact with the battens. Each batten includes: a backweb having two sides and a length, a plurality of elongated piers upstanding on each side of the backweb, each pier running the length of the backweb, and each pier having a distal surface, and a first air flow channel defined between adjacent piers and a horizontal pier cutting through adjacent piers. Air flows between airspaces created between the exterior sheathing and the siding by the batten. Air also flows through the first air flow channel and this air flow may reduce moisture entrapment between the batten and the siding or the exterior sheathing. The batten may also have a second air flow channel at an angle to the first air flow channel.

Abstract: A method for facilitating ventilation and/or drainage in a building wall, floor, and/or roof by the step of: placing a foam insulation board with an interior board face and an exterior board face, at least one board face having ventilation and/or drainage grooves and/or protrusions into the building wall, floor, and/or roof; providing vents in the building wall, floor, and/or roof adjacent end portions of the insulation board, whereby ventilation is facilitated within the wall, floor, and/or roof of the building by air moving through the vents, along the grooves and/or protrusions of the foam insulation board, and out of the vents, drainage of water is facilitated within the wall or the roof of the building by a pathway created by the grooves and/or protrusions, and moisture removal is facilitated by the passage of air during ventilation.
