The 16 inch Pop Vent Air Intake Vent with Curb Mount Flange is ideal for maintaining proper rooftop ventilation. The PV-16-C4-CMF is 16 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 16 inch Pop Vent has 200 inches of Net Free Area (NFA) and a standard 20” x 20” curb mount flange.

Installation: Ideal for low slope or flat roofs

16 inch diameter roof vents are commercial size, therefore, they are ideal for commercial settings. For those looking to ventilate their homes, please view roof vents with a smaller diameter.

This 16 inch attic vent is suitable for installation in all climate zones if installed on a roof curb. We offer roof curbs to ensure that your vent will fit over the curb seamlessly.

Because of the Curb Mount Flange, this vent can be used as a hatch to access the ductwork or attic below without damaging the roof. To determine the number of vents you may need for proper attic ventilation, see our Vent Calculator.

How it works:

The Air Intake Roof Louver provides fresh air into the attic or plenum.  Without proper rooftop ventilation, heat and moisture can 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 16 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.
