AVP's Roof Curbs will fit a Vent or Fan with a Curb Mount Flange of the same diameter. 

A Roof Curb is a raised metal frame used as a platform for mounting a roof vent or fan. As a result, this platform will provide additional height allowing for installation in all climate zones. Proper installation ensures that the accessory has a level platform for attachment. They can also work as a hatch allowing for easy access to ductwork, HVAC units, or maintenance in the attic below.

AVP's Curb Mounted Flange Vent Lines are ready to install on the appropriately sized roof curbs. This includes the Aura Vent, Pop Vent  and Round Back Vent. AVP also manufactures Attic Fans and Aura Solar Fans with curb mount flanges.

Building heavy wooden curbs can cause damage to the roofing membrane. Instead, eliminate the possibility of damage by using AVP's prefabricated roof curbs. For EPDM, PVC and TPO roofs.

The flashing allows for fasteners to securely attach the curb to the roof. Once placed, it is to be covered with roofing material for a water-tight seal.

AVP offers curbs in an array of sizes fitting vents of 3 inches to 48 inches. They are also now offered in 6 inches tall, 12 inches tall and 18 inches tall. In addition, the curbs can be insulated when needed.
