Pop Vent Roof Louver Retrofit Models are Designed to Replace Old Existing Roof Turbines.

The Pop Vent Roof Louver provides optimal attic ventilation. It removes hot air in the summer and moisture in the winter from the attic. This roof louver will fit over an existing base of the same diameter.

Pop Vents are static vents that continually exhaust air while preventing rain and snow from entering. The vertical louvers also keep out insects and animals while allowing for dynamic air flow.

A much more efficient design compared to a wind turbine vent, the Pop Vent will not allow rain and snow to get inside the roof.

The vents are designed so that they can make for a quick and easy installation. Powder coating colors are available. For any questions please see the frequently asked questions page. If you still have questions, email the sales team [email protected] or call 845-565-7770

Calculate Pop Vent Ventilation for given area

Enter below the Width and Length of the attic space you intend to ventilate. You may also enter the size of the attic directly in the "Area" field at the bottom.

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, pulldown to select the specific vent diameter to show the number of vents of that size which would ventilate the specified area with both 1/300 and 1/150 rule.

*Please note
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.
