Technical Standards

Technical standards and manuals developed by SMACNA members have worldwide acceptance by the construction and code community, as well as local and national government agencies. ANSI, the American National Standards Institute, has accredited SMACNA as a standards-setting organization. SMACNA standards and manuals address all facets of the sheet metal and HVAC industry – including duct construction and installation, indoor air quality, energy recovery, roofing and architectural sheet metal, welding, and commissioning.

Technical Inquiries

In accordance with SMACNA Policy, a formal interpretation of the literal text of SMACNA's technical manuals, guides or standards is available but only on the basis of written request or inquiry. The request must pertain to a specifically identified portion of a SMACNA technical document that does not involve published text which already provides the requested information. In considering such requests, SMACNA will not review or judge products or components as being in compliance with the document or publication.
