3 inch Roof Vent | Round Back Static Roof Vent | Model RBV-3-C4<\/strong><\/h3>\n

The\u00a03 inch Round Back Static Roof Vent is 3 inches in diameter and has a 4 inch tall collar. In other words, this vent has 4 inches of clearance between the base and the inner louvers. The model RBV-3-C4 has 7 inches of net free area (NFA) which means each vent will ventilate 30 square feet of space.<\/p>\n

To determine the number of roof vents<\/a> you may need, see the Vent Calculator<\/a>. Each 3 inch static vent comes with an 8\u201d x 8\u201d square flange.<\/p>\n

Where to install:<\/strong><\/h4>\n

This 3 inch roof vent is ideal for roofs with a 3\/12 to 12\/12 roof pitch. For a pitch of 3\/12 or greater<\/a>, install this vent no more than 3 feet from the ridge of the roof. Doing this will enable you to install your static vent in all climate zones<\/a>.<\/p>\n

How it Operates<\/strong>:<\/h4>\n

The 3 inch static roof vents will work in conjunction with bathroom fans and range hoods.<\/p>\n

The vent lid is one piece of spun aluminum that 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

The inner louvers of the roof vent keep insects and animals from entering the attic. Meanwhile, the louvers will also allow the air to flow freely to the outside.<\/p>\n

This 3 inch roof vent is great for residential roof applications because of its low profile. These vents can also be powder coated to match the color<\/a>\u00a0of asphalt shingle roofs.<\/p>\n
