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.\u003c\/p\u003e\u003cp\u003e\u003cem\u003eCut the ridge sheathing carefully and follow the manufacturer's installation instructions and local codes; work on ridges only with proper fall protection.\u003c\/em\u003e\u003c\/p\u003e\u003chr\u003e\u003cp\u003e\u003cstrong\u003eInstall the CertainTeed filtered Class-A fire rated ridge vent for year-round attic protection and airflow.\u003c\/strong\u003e\u003c\/p\u003e","brand":"CertainTeed","offers":[{"title":"Default Title","offer_id":67583350341999,"sku":"CERRVCA7","price":21.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0830\/3499\/7051\/files\/CERRVCA7_0.jpg?v=1790406897","url":"https:\/\/superarbor.io\/products\/certainteed-filtered-ridge-vent-class-a-fire-rated-7-in-x-4-ft-black","provider":"Super Arbor","version":"1.0","type":"link"}
