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 with Curb Mount Flange, Intake Pop Vents with Curb Mount Flange and Round Back Vents with Curb Mount Flange. We also manufacture Attic Fans with Curb Mount Flange and Aura Solar Fans with Curb Mount Flange when you need powered vents.

Building heavy wooden curbs can cause damage to the roofing membrane. Instead, eliminate the possibility of damage by buying AVP's prefabricated ones. Typically used for EPDM, PVC, and TPO roofs.
The flashing allows for mechanical fasteners to be used so that the curb is securely bonded 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. In addition, the curbs can be insulated when needed.
