The CertainTeed filtered ridge vent is a 7 in. x 4 ft. black stick vent in flame-retardant polypropylene, Class-A fire rated.

Expert Verdict — Reviewed by the SuperArbor Pro Desk
The external baffle is what separates a performance ridge vent from an open slot: it prevents weather wash-over from driving rain into the attic while pulling air across the sheathing. At 16 sq in. per foot this is a high-output vent, which makes meeting the 1/150 ratio easier on big attics. Keep it paired with adequate soffit intake, or the vent will underperform.
Cut the ridge sheathing carefully and follow the manufacturer's installation instructions and local codes; work on ridges only with proper fall protection.
Install the CertainTeed filtered Class-A fire rated ridge vent for year-round attic protection and airflow.
