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

Save time and money with AVP's lightweight, heavy-gauge aluminum roof curbs. It’s true; you don’t have to build your own heavy wooden curbs anymore.

A Roof Curb is a 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 Aura Vent, Intake Pop Vents and Round Back Vents. AVP also manufactures Attic Fans with Curb Mount Flange and Aura Solar Fans with Curb Mount Flange for powered ventilation.

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

The flashing allows for mechanical 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 3 heights. In addition, the curbs can be insulated when needed.
