Square Roof Curb 17" Square x 12" High, Model SRC-14-H12
This roof curb is 17" long by 17" wide and 12" high and is only compatible with roof vents or fans that have a curb mount flange 17.5 inches square. Active Ventilation Products' prefabricated roof curbs are for flat or low-slope membrane roofs.
A roof curb is a metal box that acts as a base for a roof vent or fan. As a result, this base will provide additional height. Proper installation ensures that the accessory has a level platform for attachment. Roof curbs can also serve as a hatch, providing easy access to ductwork, HVAC units, or attic maintenance.
Traditionally, roofers build wooden roof curbs on the roof during the membrane installation. However, building wooden curbs can cause damage to the roof membrane. This happens because of the cutting of lumber, as well as loose nails or screws that end up getting walked by the crew. Using prefabricated aluminum roof curbs eliminates the need to build wooden boxes and reduces the chance of damaging the roof.
A key safety feature is that aluminum curbs are not flammable, unlike wooden roof curbs. Most roof curbs vent out heat from range hoods or HVAC units. This heat can cause wooden curbs to burn. However, aluminum will not burn, rust, or corrode. Aluminum curbs are safer and easier to clean.
Installation of this roof curb is for EPDM, PVC, and TPO roof membranes
The flashing on the roof curb enables mechanical fasteners to attach the curb to the roof securely. Once placed, it must be covered with closed square curb flashing, "roofing material" to ensure a watertight seal.
AVP offers roof curbs in various sizes and with the option for insulation.
The curb mount flange, vent, and fan lines are ready to install on AVP's roof curbs. This includes Aura Vent, Pop Vents, and Round Back Vents as well as Attic Fans and Aura Solar Fans for powered ventilation.
