In other words, this vent has 2 inches of clearance between the base and the inner louvers. The model RBV-12-C2-IN has 113 inches of net free area (NFA) which means each vent will ventilate 470 square feet of attic space.<\/p>\n<p><em><strong>This vent is a hybrid design where 1\/3 of the collar is closed to prevent runoff from entering.\u00a0<\/strong><\/em><\/p>\n<p>To determine the number of roof vents you may need, see the <a href=\"https:\/\/roofvents.com\/active-ventilation-products-attic-vent-calculator\/\">Vent Calculator<\/a>. Each 12 inch roof vent comes with a 17\u201d x 17\u201d square flange.<\/p>\n<h4><strong>Benefits:<\/strong><\/h4>\n<ul>\n<li>Keeps your home comfortable and energy efficient<\/li>\n<li>Louver design prevents water from splashing inside<\/li>\n<li>Inner louvers prevent insects and animals from entering the vent<\/li>\n<li>Round aerodynamic design can withstand harsh weather<\/li>\n<li>Noiseless \u2013 does not require electricity to exhaust air<\/li>\n<\/ul>\n<h4><strong>Where to install: Lower end of the roof<\/strong><\/h4>\n<p>This 12 inch roof vent is ideal for roofs with a 2\/12 to 5\/12 roof pitch\u00a0in\u00a0<a href=\"https:\/\/roofvents.com\/intake-vent-clearance-for-all-climates\/\">climate zones 1-3<\/a>. This intake roof vent should go near the lower end of the roof.<\/p>\n<p>To determine the number of vents you may need for proper attic ventilation, see the <a href=\"https:\/\/roofvents.com\/active-ventilation-products-attic-vent-calculator\/\">Vent Calculator<\/a>.<\/p>\n<h4><strong>How it Operates<\/strong>:<\/h4>\n<p>The Round Back Intake Roof Vent will provide fresh air into the attic. Without proper rooftop ventilation, heat and moisture may cause decay of the structure. As a result, ventilation helps to make a home more comfortable and energy efficient.<\/p>\n<p>The top 1\/3 of the collar is closed to prevent runoff from splashing inside the vent. <em><strong>This side is to be facing the ridge.\u00a0<\/strong><\/em><\/p>\n<p>The vent lid is manufactured from one piece of spun aluminum which prevents rain and snow from entering the attic. The round design is aerodynamic to withstand wind pressure exceeding 200 mph. All Round Back roof vents are resistant to corrosion and will remain rust free for the life of the roof.<\/p>\n<p>The inner louvers of the roof vent keep insects and animals from entering the attic. The louvers also allow the air to flow freely to the outside.<\/p>\n<p>This 12 inch roof vent is also great for residential roof applications because of its aesthetically pleasing appearance. Having a low profile, the Round Back Vents can also be <a href=\"https:\/\/roofvents.com\/color-chart-2\/\">painted to match the color<\/a>\u00a0of asphalt shingle roofs.<\/p>\n<p>For any questions please see the\u00a0<a href=\"https:\/\/roofvents.com\/frequently-asked-questions\/\">frequently asked questions page<\/a>.
