Cor-A-Vent REV-11 Revolution Rolled Ridge Vent 11"x20' Roll Coravent

This is the first shingle-over ridge vent made from 100% pre-consumer recycled plastic. Revolution is the only truly "Green" ridge vent available. This helps reduce heating and cooling loads when used in conjunction with balanced intake ventilation. The 20-foot-long plastic vent core is made entirely from the same polypropylene plastic used to manufacture all of Cor-A-Vent's other products. Revolution's precisely spaced ventilation channels provide 12 square inches of Net Free Vent Area per lineal foot to promote the removal of damaging moisture from inside your attic. The structural design supports power-nailability for easy installation on asphalt shingle roofs. Won't crack or compress like other vents. Comes with 2 coils of 1 3/4-inch nails.
