Embodiments discussed herein are directed to closure strips used to provide ventilation in roofs or other building components.
Venting material may be used in connection with some roofing systems. In some configurations, venting material may be installed to provide a seal between roof panels, such that air is allowed to pass between the roof panels. Typically, one or more of the roof panels will have an uneven surface containing one or more raised portions and one or more recessed portions. Typically, venting materials are precut to fit a specific roof profile. Specifically, the venting materials may include a number of cuts or pockets that are adapted to engage a particular raised portions of a roof panel.
Due to this aspect of venting materials, the dimensions of the roof profile must typically be measured or known prior to the specific material being ordered or purchased. Once these measurements are acquired, the appropriate size of venting material may be ordered from a vendor. Provided no errors are made in the measurements or other steps of the ordering process, a vent of the appropriate size may be installed for the specified roof profile.
Embodiments discussed herein are directed to sealing component that is installed across an uneven surface without having dedicated segments for engaging raised and recessed portions of the uneven surface. The sealing component may include an elongated strip of a lofted, compressible nonwoven material. The elongated strip may include an adhesive on one or two sides. In a pre-installation configuration, the strip may be wound into a coil.
One embodiment is directed to a ventilation system component, having an elongated strip of air-permeable compressible nonwoven fibers and an adhesive layer disposed on at least one side of the elongated strip. The fibers may be polyester, nylon, polyethylene, polypropylene, or any other natural or man-made fiber.
One embodiment is directed to a method of installing a ventilation system component, comprising: applying an elongated strip of nonwoven material to a major roof panel, the elongated strip of nonwoven material conforms to one or more irregularities on the surface of the major roof panel; and attaching a minor roof panel to the major roof panel, wherein a portion of the minor roof panel is in contact with the elongated strip of nonwoven material.
One embodiment is directed to a method of installing a ventilation system component, comprising: applying an elongated strip of nonwoven material to a minor roof panel; and attaching the minor roof panel to a major roof panel, wherein a portion of the major roof panel is in contact with the elongated strip of nonwoven material, the elongated strip of nonwoven material conforms to one or more irregularities on the surface of the major roof panel.
Embodiments discussed herein are directed to an apparatus or component for providing ventilation in roof. The apparatus or component may be a sealing component that includes an elongated strip of compressible nonwoven material. The elongated strip of compressible nonwoven material may be installed between roof panels. The elongated strip of compressible nonwoven material will provide a seal between the roof panels that facilitates ventilation, by allowing air to pass through. The nonwoven material strip may be used in an intake or exhaust area of a ventilation system. In this way, the nonwoven material strip allows air to pass between the exterior and the interior of a house or other building. The elongated strip of compressible nonwoven material may be installed without the use of dedicated segments that are adapted to fit a specific roof profile.
As shown in
The physical properties of the strip 100 provide the strip 100 with the ability to compress and/or form around irregularities on the uneven surface 108. In one embodiment, the strip 100 is formed from a plurality of polyester, nylon, polyethylene, polypropylene, or other man-made or natural fibers. The polyester, nylon, polyethylene, polypropylene, or other man-made or natural fibers provide the strip 100 with the ability to conform to a specific roof profile by compressing around raised portion of the roof and/or expanding or remaining the same size to keep in contact with recessed portions of the roof. Unlike polyurethane fibers used in prior art materials, the polyester fibers of the present embodiment do not wick moisture into the interior or other portions of the strip 100. The polyester fibers of the strip 100 may be coated in a rubber base material. The rubber base material may provide fire proofing to the strip 100, in one embodiment. In one embodiment, the strip 100 is manufactured as a single baffled layer of non-woven material coated with a phenolic resin component. In one embodiment, the strip 100 has a net free area or 20 square inches per linear foot of material.
As shown in
As shown in
The strip 100 may be installed at an intake or an exhaust portion of a roof ventilation system, such as the ridge cap location shown in
In addition to being used in connection with a ridge cap, the strip 100 may be used in connection with other roof portions or joints as shown in
In an installation process, the strip 100 may be unrolled and attached to a portion of either the major or minor roof panels by use of the adhesive 120, which is applied to the surface of the strip 100. By way of example and not limitation,
Whether the strip 100 is initially installed on the major or minor roof panels, the minor roof panel may be secured to the major roof panel using an appropriate tool. In one embodiment, a 3300 RPM screw gun may be used. The strip 100 is adapted for easy installation. Specifically, a utility knife or scissors may be used to cut the strip to ensure the strip 100 conforms to the desired length. The strip 100 may be caulked without a connector or end plugs. Multiple strips 100 may be used in combination to form a ventilation strip of any size. Adjacent strips 100 may be “butt-fit” such that end portions of the strips are in contact.
Turning now to a method of installing a strip 100 in accordance with implementations discussed herein, references is made to the flow chart shown in
By way of example and not limitation, the embodiments illustrated herein include a minor roof panel having a smooth surface and major roof panel having an uneven surface. It should be appreciated that other roof configurations may be used in connection with the strip 100. Specifically, the strip 100 may be installed with a minor roof panel having an uneven surface and a major roof panel having a smooth surface.
The foregoing merely illustrates certain principles of particular embodiments. Various modifications and alterations to the described embodiments will be apparent to those skilled in the art in view of the teachings herein. It will thus be appreciated that those skilled in the art will be able to devise numerous systems, arrangements and methods which, although not explicitly shown or described herein, embody the principles of the invention and are thus within the spirit and scope of the present invention. From the above description and drawings, it will be understood by those of ordinary skill in the art that the particular embodiments shown and described are for purposes of illustration only and are not intended to limit the scope of the present invention. References to details of particular embodiments are not intended to limit the scope of the invention.
The present application claims the benefit under 35 U.S.C. §119(e) to U.S. Provisional Patent Application No. 61/308,786 (“the '786 application”), which was filed on Feb. 26, 2010, and entitled “Closure Strip”. The '786 application is incorporated by reference into the present application in its entirety.
