5 inch Roof Curb, 6 inch Height | Fits 5 inch Vent or Fan | RC-5-H6

The RC-5-H6 is a roof curb designed to fit the diameter of a 5 inch vent or fan. These Curbs are only compatible with vents or fans that have a curb mounted flange of the same diameter. AVP's prefabricated Roof Curbs are designed for flat roof or low sloped roof applications.

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.

Building heavy wooden curbs can cause damage to the roofing membrane. Instead, eliminate the possibility of damage by buying AVP's prefabricated ones.

Installation: Typically used for EPDM, PVC and TPO roofs - Flat Roof Installation

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 3 heights. In addition, the curbs can be insulated when needed.

The Curb Mounted Flange Vent Lines are ready to install on the appropriately sized roof curbs. This includes Aura Vent with Curb Mount FlangeIntake Pop Vents with Curb Mount Flange and Round Back Vents with Curb Mount Flange. As well as Attic Fans with Curb Mount Flange and Aura Solar Fans with Curb Mount Flange when you need powered vents.
