A roof batten for use in spacing tiles or similar exterior roofing members from a roof overlayment is provided. In one embodiment, the batten includes at least one layer of a corrugated plastic material with a pair of generally planar plies and a convoluted ply cooperating with the planar plies to define a multiplicity of passages. The passages allow drainage of water infiltrating the tiles and further promote drying. REEXAMINATION RESULTS The questions raised in reexamination request no. 90/007,487, filed Mar. 19, 2004 have been considered and the results thereof are reflected in this reissue patent which constitutes the reexamination certificate required by 35 U. S. C. 307 as provided in 37 CFR 1.570(e), for ex parte reexaminations, or the reexamination certificate required by 35 U. S. C. 316 as provided in 37 CFR 1.997(e) for inter partes reexaminations.

Roof batten

A wall system for a structure including elongate furring strips having a multiplicity of transversely oriented air passages. The elongate furring strips are arranged on a first envelope layer of a wall and covered with a second envelope layer. The furring strips space the first and second envelope layers apart, forming a plurality of enclosed cavities or air spaces. The cavities are in fluid communication with each other through the air passages in the furring strips, and may be in fluid communication with the outside atmosphere. Air is thusly enabled to circulate from the outdoors through substantially all portions of the cavities, promoting drying of the first and second envelope layers, which may be sheathing and finish siding.

An industrial reel wrap is designed for wrapping an industrial reel having a central spool and a pair of end plates connected thereto. The reel wrap includes a central portion that is spannable across a distance between the end plates of the reel. The reel wrap additionally includes first and second side portions that are coupled to the central portion. The first and second side portions each include a number of tabs along the length of the reel wrap. The tabs are securable to the exterior surface of each the end plates, the first and last of the tabs are preferably overlapped to completely enclose the industrial reel. The tabs are separated from the central portion by a double crease seam to enable easier folding of the tabs. The reel wrap may be scored to enable compact folding for shipment.

A precipitation resistant ventilator for a structure enclosing an interior space. The ventilator encloses a space that is in communication with the structure interior space. A thin sheet of air permeable water resistant material is disposed within the ventilator interior. The thin sheet of air permeable water resistant material forms a barrier that excludes the entry of precipitation and other foreign matter into the roof structure while still allowing air exchange.

A ridge cap vent for enabling air exchange between an interior and an exterior portion of a roof and a method of installing the ridge cap vent are provided. The ridge cap vent is conformed to be disposed between an upper ridge cap member and a lower member. The ridge cap vent may be formed from a corrugated plastic material and includes a multiplicity of air passages extending generally transversely to a longitudinal axis of the ridge cap vent.

In one embodiment, the batten includes at least one layer of a corrugated plastic material with a pair of generally planar plies and a convoluted ply cooperating with the planar plies to define a multiplicity of passages. The passages allow drainage of water infiltrating the tiles and further promote drying.

Ridge cap type roof ventilator

An air deflector for installation with a roof ventilator having a pair of vent parts defining a multiplicity of air passages, the air deflector comprising a base member and a generally upright air flow blocking member extending upwardly from the base member at a generally acute angle of 75.degree.. Two air deflectors extend along the entire length of the roof ventilator proximate to the outer edge of each opposing vent part. The base member is disposed between the bottom surface of the corresponding vent part, and the upright air flow blocking member confronts and is spaced apart a selected distance from the outer edge of the vent part and angles inwardly slightly toward the vent part. The top edge of the upright air flow blocking member angles slightly outward away from the vent part, and is disposed at approximately the same height as the top panel of the roof ventilator. The base member includes end notches designed and positioned to facilitate installation and retrofitting of the air deflector with a wide variety of existing roof ventilator configurations, and spacing of the upright air flow blocking member at desired distances from the outer edge of the vent part.
