Roof Curb 15" Square x 12" High, Model SRC-12-H12

This roof curb is 15" long by 15" wide and 12" high and is only compatible with roof vents or fans with a curb mount flange. Model SRC-12-H12 will fit a vent or fan with a curb mount flange measuring 15.5 inches.  Active Ventilation Products' prefabricated roof curbs are for flat or low-slope membrane roofs.

A roof curb is a metal frame that acts as a base for a roof vent or fan. As a result, this base will provide additional height, allowing for installation in all climate zones. Proper installation ensures that the accessory has a level platform for attachment. Roof curbs can also work as a hatch, allowing easy access to ductwork, HVAC units, or maintenance in the attic below.

Traditionally, roofers build wooden roof curbs on the roof at the time of 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.

An important safety feature is that aluminum curbs are not flammable like 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 easy to clean.

Installation of this roof curb is for EPDM, PVC, and TPO roof membranes

The flashing on the roof curb allows for mechanical fasteners to attach the curb to the roof securely. Once placed, it is to be covered with roofing material for 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. It also has attic fans and aura solar fans for powered ventilation.

The diameter size of all roof vents determines the Net Free Area, also known as the "NFA". NFA is the measured amount of opening each vent offers at each specific size. to be available for venting air through a specific vent size. The calculator below will find the overall number of vents needed to effectively ventilate the targeted attic space.

Once you have the area, the numbers shown below are the number of vents of that size which would ventilate the specified area with both 1/300 and 1/150 rule.

*Please note
The roof vent calculation values shown above are for the exhaust portion of the roof. The same amount of net free air inches is needed for air intake as well. Proper roof ventilation consists of 50% air exhaust and 50% air intake.
