Abstract: Provided herein are rafter vents including a ventilated mat extending along a roof structure, the ventilated mat comprising a plurality of entangled filaments, and a backing adhered to the ventilated mat along a surface of the ventilated mat configured to face opposite the roof structure.

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 sound-deadening product for a flooring system with a subfloor may be installed by a single installer. The sound-deadening product has a sound-deadening upper portion with a bottom surface and a subfloor contacting layer affixed to the bottom surface of the sound-deadening upper portion. The subfloor contacting layer may include a film or be a laminate. The laminate may include a nonwoven sheet and a film. The nonwoven sheet is generally co-extensive with the sound-deadening upper portion. The nonwoven sheet is adhered to the bottom surface of the sound-deadening upper portion. The film is generally co-extensive with the nonwoven sheet. The film is a polymer film with a thickness ?3 mils. An upper surface of the film is adhered to a bottom surface of the nonwoven sheet, and a bottom surface of the film is in contact with the subflooring. A method for single installer installation of the sound-deadening product 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 corner flashing assembly for providing a moisture barrier at corners at the base of a foundation wall. The corner flashing assembly according to the invention comprises an upper corner piece and a lower corner piece. The upper and lower corner pieces are dimensioned such that, when installed, the lower edge of the upper corner piece and the upper edge of the lower corner piece overlap a certain distance, thereby allowing adjustability to accommodate varying dimensions of construction blocks, yet providing an effective moisture barrier. Portions of the corner pieces that will come into contact with mortar are coated with asphalt to improve the adherence of the mortar to the flashing.
