For a residential system, what is the minimum thickness of 16-inch aluminum duct?

In residential ductwork, the thickness of aluminum duct is specified in terms of gauge, which determines the strength and durability of the material. The minimum thickness of a 16-inch aluminum duct is established to ensure it can withstand the pressures and conditions commonly found in HVAC applications.

Selecting 24 gauge as the minimum thickness is rooted in industry standards, balancing the duct's structural integrity and its ability to convey air efficiently. Thicker gauges provide greater strength and reduce the risk of damage or deformation, which is crucial for maintaining desired airflow and system efficiency.

Therefore, the choice of 24 gauge reflects the need for a reliable and long-lasting duct system in residential settings, ensuring proper airflow and reducing maintenance issues over time. This gauge provides sufficient durability without adding unnecessary weight or cost, making it an optimal choice for standard residential duct applications.
