Air Exhaust Roof Louver | Pop Vent | PV-24-C2

The 24 inch Pop Vent Roof Louver is for ventilating steep slope roofs. PV-24-C2 is a 20 inch diameter roof vent with a 2 inch tall collar. In other words, this vent has 2 inches of clearance between the base and the inner louvers. The PV-24-C2 has 452 inches of net free area (NFA) and comes with a 36” x 36” square flange.

Where to Install:

If installed on the upper portion of the roof, no more than 18 inches down from the peak, this attic vent can go on a roof with a pitch of 4/12 or greater in all climate zones. The 24 inch Pop Vent is great for commercial roof applications whereas if you are looking for residential ventilation we recommend looking into a smaller size.

To determine the number of vents you may need, see our Vent Calculator.

How it works:

The Air Exhaust Roof Louver removes moisture in the winter and heat in the summer to extend the life of the building structure. It helps to keep insulation dry in the winter to prevent mold. In addition, the round design is aerodynamic to withstand wind speeds up to 200 mph.

The 24 inch Pop Vent roof louver is great for residential roof applications because of its low profile. It can also be painted to match the color of the asphalt shingles.

For any questions please see the frequently asked questions page. If you still have questions, email the sales team at [email protected] or call 845-565-7770. If you are looking to determine the pitch of your roof, see the Roof Pitch Diagram.

Pop Vents are UL Listed and rated up to 50+ PSF or wind pressure above 200 MPH.  Certified by Texas Department of Insurance, Florida State Approved & Conforms to the Standards of CALFIRE.
