SMACNA Duct Construction Standards Application

A comprehensive article on duct system codes and standards (SMACNA, ACCA, ASHRAE) covering sheet metal gauges, joint reinforcement, pressure classifications, and sealing. Essential for understanding how specs apply on real-world jobs. A new article specifically addresses SMACNA guidelines for vertical duct support, listing prevented issues like sagging, structural failure, and energy loss. Additionally, SMACNA has released on-demand video modules on Rectangular Industrial Duct Construction Standards, covering classifications, critical loads, and panel gage/stiffener selection—ideal for hands-on learning. A recent field report on mold/leaks in Palm Beach duct systems reinforces the importance of mastic sealing and proper supports per SMACNA/ASHRAE standards.
