Top 5 Advantages of Round Duct Fittings

One of the most obvious advantages of round duct fittings is that they leak significantly less than other types of ductwork (specifically rectangular ductwork). One of the major reasons for this is that spiral round ducts don’t have longitudinal seams, which are one of the main causes of leakage in rectangular ducts. Round duct fittings are also typically installed with fewer joints and points of connection than rectangular duct fittings, which also helps prevent air leakage.

Spiral round ducts are made using less material than rectangular ducts with the same airflow capacity, which means that round duct fittings are cheaper to manufacture, and by extension, cheaper to purchase.

Round duct fittings are actually a lot easier to install than rectangular duct fittings, so when you decide to go with round ductwork for your HVAC system, you will typically save a lot of money on installation costs.

Spiral round ducts have shallower angles than rectangular ducts, which means that when air is moving through round ductwork, it loses less airspeed than when it moves around sharp turns in rectangular ductwork, and consequently, round duct fittings are more energy efficient than their rectangular counterparts. Spiral round ducts also have less surface area than rectangular ducts, which means they are better able to retain heat (because they lose less of it through the duct walls).

In addition to their many functional advantages, round duct fittings are visually appealing. Spiral ductwork is a lot better at blending into the surroundings than rectangular ductwork. Spiral ductwork has a more subtle quality, and is easier to disguise or make look intentional than its counterpart. Exposed rectangular ductwork tends to look messy and unfinished, but exposed round ductwork can actually make a place look hip, modern, and cool.
