The RC-5-H12 is a roof curb that will fit the diameter of AVP's 3-inch vents or fans. These Curbs are only compatible with roof 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.
The RC-5-H12 has a throat diameter of 7 inches, length and width of 8 inches, and an overall height of 12 inches.
A Roof Curb is a metal frame to act 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.
The flashing allows for mechanical fasteners to securely bond the curb to the roof. Once placed, it is to be covered with roofing material for a water-tight seal. AVP's roof curbs are typically for flat roof installation.
In addition, AVP offers Curbs in an array of sizes with the option for insulation.
The 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. As well as Attic Fans with Curb Mount Flange and Aura Solar Fans with Curb Mount Flange when you need powered vents.
