The 14 inch Pop Vent Air Intake Vent is ideal for maintaining proper attic ventilation. The PV-14-C4 is 14 inches in diameter with a 4 inch tall collar. In other words, this vent has 4 inches of clearance between the base and the inner louvers. In addition, the 14 inch Pop Vent has 144 inches of Net Free Area (NFA) and a standard 19” x 19” square flange.
Air intake vents allow outside air to enter into attics and ventilation spaces.
This 14 inch intake roof vent is suitable for installation in climate zones 1-3. This intake roof vent should be installed near the lower end of the roof.
To determine the number of vents you may need for proper attic ventilation, see our Vent Calculator.
The Air Intake Roof Louver provides fresh air into the attic or plenum. Without proper rooftop ventilation, heat and moisture may cause decay of the structure. This roof vent also helps to keep insulation dry in the winter to prevent the growth of mold.
Additionally, the round design is aerodynamic to withstand wind speeds up to 200 mph. The 14 inch Pop Vent is great for residential roof applications because of its low profile. It can also be painted to match the color of the asphalt shingles.

The diameter size of all roof vents determines the Net Free Area, also known as the "NFA". NFA is the measured amount of opening each vent offers at each specific size. to be available for venting air through a specific vent size. The calculator below will find the overall number of vents needed to effectively ventilate the targeted attic space.
Once you have the area, the numbers shown below are the number of vents of that size which would ventilate the specified area with both 1/300 and 1/150 rule.
The roof vent calculation values shown above are for the exhaust portion of the roof. The same amount of net free air inches is needed for air intake as well. Proper roof ventilation consists of 50% air exhaust and 50% air intake.
