What is the minimum thickness for galvanized duct used in residential construction?

The minimum thickness for galvanized duct used in residential construction is based on standards set forth in building codes and industry guidelines. The specified thickness of 0.013 inches reflects a balance between adequate strength and durability while minimizing weight and cost.

This thickness is necessary to ensure the ductwork can withstand the pressure from airflow, resist dents and damage during installation and service, and maintain an effective seal to prevent air leakage. Thinner ducts may not provide the required structural integrity and could lead to issues like noise, reduced efficiency, and a shorter lifespan.

This standard is consistent with general practices in ventilation and duct construction, ensuring that the ducts installed in homes are robust enough for long-term use. Materials that meet or exceed this minimum thickness contribute to the overall performance and energy efficiency of the HVAC systems in residential properties.
