The 48 inch roof curb has an outer diameter of 51 inches. This mean, it will fit a vent with curb mounted flange of the same diameter. Our prefabricated Roof Curbs are designed for flat roof or low sloped roof applications.
A Roof Curb is essentially a metal box used as a platform for a roof vent or fan. As a result, this platform will provide the vent additional height allowing for installation in all climate zones.
Building heavy wooden curbs can cause damage to the roofing membrane. Instead, eliminate the possibility of damage by buying our installation roof curbs.
The flashing of the curbs allow for mechanical fasteners to be used so that the curb is bonded to the roof. Once placed, it is to be covered with roofing material for a water tight seal.
We offer our Curbs in an array of sizes varying from 4 inches to 48 inches. In addition, the curbs can be insulated when needed.
Our Curb Mounted Flange Vent Lines are ready to install on the appropriate 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.
