Lower cost
The installation of spiral ductwork — including labor, transportation, warehousing, and packaging — can cost up to 50% less than traditional rectangular duct. Because of its strength and rigidity, spiral duct requires fewer supporting components and fewer tools to install. It is typically made of a lighter material than rectangular duct, which makes installation easier; in fact, it can often be installed by just one or two people rather than a whole team.
Higher efficiency
Air leakage at duct joints is a common problem for traditional rectangular ductwork, which leads to energy loss and poor system efficiency. Spiral duct systems, however, typically meet or exceed industry air-leakage standards. With less leakage, the cost of heating, cooling, and filtering conditioned air is much lower and indoor air quality is a lot higher. The spiral design of the system keeps internal air pressure equal, allowing the air to flow evenly and efficiently.
Less noise
Noise breakout is another issue that is common with rectangular ductwork. The design of the rectangular system causes air to move around sharp edges, dampers, and turning vanes. This obstruction contributes to noisy turbulence; however, spiral ducts have smoother edges that eliminate reverberation, creating less noise.
