Open Duct | Closed Duct |
Pair with compatible fittings and accessories.
Galvanized Steel—Corrosion resistant and affordable, galvanized steel is the most commonly used ductwork material.
Open Duct—Easier to cut with snips than closed duct, so it’s good for repairing or retrofitting an existing system. Snap the seams together by hand—no tools required.
Closed Duct—With a closed seam, this duct is stronger and less prone to air leaks than open duct. However, it’s not as quick to modify when installing.
