What type of ductwork is supported by SMACNA HVAC Duct Construction Standards?

The type of ductwork supported by SMACNA HVAC Duct Construction Standards is sheet metal ductwork. These standards provide guidelines and best practices for the design, fabrication, and installation of duct systems. Sheet metal ductwork is commonly used in HVAC applications because of its durability, efficiency, and effectiveness in handling air flow.

SMACNA (Sheet Metal and Air Conditioning Contractors' National Association) focuses on ensuring that ductwork meets specific criteria for air leakage, insulation, and structural integrity, which are vital for maintaining system performance and energy efficiency. By adhering to these standards, contractors can achieve a high level of quality and reliability in their duct installations.

While flexible ductwork, insulated ductwork, and PVC ductwork have their own applications in specific situations, they are not primarily covered by the SMACNA standards, which focus on the construction and regulation of sheet metal systems. This ensures that contractors have a comprehensive resource for creating duct systems that are both high-performing and compliant with industry regulations.
