The 16 inch Pop Vent Retrofit is for replacing existing attic vents. The PV-16-RF is 16 inches in diameter and has 200 inches of Net Free Area (NFA).
This roof vent will fit over an existing base with a diameter of 16 inches. It's a perfect replacement for turbine vent heads. Turbine vents frequently stop turning entirely due to corrosion. However, Pop Vent Retrofits are made from durable rust-free aluminum.
The Pop Vent Retrofits will fit over an existing base allowing for easy installation without damaging the roofing material. Intake roof vents allow outside air to enter into attics and ventilation spaces. As a result, creating proper ventilation.
How it works:
The 16 inch Pop Vents is a static vent that will continually ventilate the air while preventing precipitation from entering. The vertical louvers also keep out insects and animals which allows for proper airflow. In addition, the round design is aerodynamic to withstand wind speeds up to 200 mph.
For help with installing, please view the Installation Guides. Hardware is included to attach to the base or pipe. 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
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.
