COR-A-VENT® has the answer for stopping all forms of weather infiltration with the X-5 ridge vent: The Complete Solution – superior ventilation performance and the ability to stop rain and snow infiltration cold...even in weather extremes.
X-5 employs dual protection to stop infiltration. First is the AWF – the active weather foil, a specially designed, wind-activated, weather impenetrable valve – permanently attached to the bottom layer of our X-5 vent material. The AWF will stop wind driven rain from penetrating your roof cavity. Second is the enhanced snow screen, an air-permeable filter that keeps out snow, even at low wind speeds, while still allowing hot, moist air to flow out of the attic.
How does the AWF work? We've engineered the valve to close at 10 MPH (± 2 MPH). The leading (windward) edge of the AWF, which is shaped like an airfoil, catches the wind blowing at it, whether directly or at an angle, and snaps shut. Meanwhile, on the downwind (leeward) side, the vent remains open and continues to exhaust hot, moist air from the attic. Below 10 MPH, the valve opens completely for positive ventilation from both sides of the vent. The AWF effectively blocks weather from entering through the vent's flutes. Dade County acceptance1 and our own in house rain tests confirm this. The harder the wind blows, the tighter the AWF seals.
How long will the AWF last? Developed from a special formulation of Reemay® non-woven with a UV inhibited proprietary coating, it's guaranteed to last. Tested to the same standards as composition shingles, the AWF fabric was subjected to a 5000-hour exposure test from a Xenon Arc weatherometer. That's the equivalent of 25 years exposure to south Florida or Death Valley sun. The results - no significant embrittlement or degradation.
X-5 is made from a special 4mm sheet of extruded PP. This means less restriction and more airflow. At the same time, it has 17 sq. inches of NFVA (Net Free Vent Area) per lineal foot, which exceeds all national building code requirements. X-5 will work with shingle, metal, tile and cedar roofs and is also a perfect Roof-To-Wall vent. X-5 is available in 11" and 81/2" widths and is packaged 9 four foot pieces per box.
When performance counts – count on X-5. From COR-A-VENT – continuing our tradition as – "The Leader In Innovative Rooftop Ventilation®".
Like our V-300 vent line, X-5 comes in convenient 4' sections, cuts easily with a utility knife and is power nailable 2. Packed 9 – 4' pcs. to a carton, with 4 EC-400 end caps, it's easy to handle going up the ladder and on the roof.
** Important information about cap shingles and the X-5 Ridge Vent. The cap shingle on the X-5 Ridge vent should not extend more than 1/2" beyond the top edge of the vent. If you are using metric shingles the cap shingles must be trimmed to 12" wide for proper function of the Active Wind Foil.
X-5 is covered under U.S. patents 6,213,868; 5,921,863; 5,704,834; 5,542,882 & Des. 465,839. Other patents pending.

Revolution used for Joplin, MO project
Cor-A-Vent recently donated Revolution Rolled Ridge Vent to the Tulsa, OK Habitat for Humanity to be used in their re-build project in Joplin, MO to help re-build that community in the wake of the devastating May 22 tornado. You can read about the Ten for Joplin project here: http://www.tenforjoplin.org/
Community leaders announced the project at a news conference on the site of one of the new homes. The build is scheduled between Oct. 29 and Nov. 13 and will be take place in a neighborhood of Joplin that was in the affected area.
Ten for Joplin’s vision is to ignite volunteer efforts to rebuild Joplin by setting an example of what can be accomplished when businesses and communities come together to help one another.
“This is an exciting partnership that will not only provide 10 homes for 10 families, but will demonstrate the many benefits communities gain when working together,” said Joplin City Manager Mark Rohr. “As part of the Midwest, Tulsa Habitat and all of their volunteers and sponsors recognize the powerful reward one gets when helping their fellow neighbor.”
Donations and volunteers are needed to make this project a reality. The goal is to raise $800,000 in funds plus gifts in-kind and get 3,000 volunteers to support us on the blitz build. To date, Ten for Joplin has secured $400,000 toward this goal.
Companies that have signed up to be house sponsors are Hilti, Henry & Anne Zarrow Foundation, BKD CPAs & Advisors, Samson, TD Williamson, Inc. and Chase. Advanced Industrial Devices, Inc. also has signed up to sponsor half a house. Gift in-kind donations have been provided by Hilti, Thermal Windows, Inc. and Cor-A-Vent. United Way contributed tornado relief funds to help with the purchase of the ten lots.
