Chantilly, Va. (December 10, 2021) — The Sheet Metal and Air Conditioning Contractors’ National Association (�鶹���), the leader in promoting quality and excellence in the sheet metal and air conditioning industry, today released the eighth edition of its Fibrous Glass Duct Construction Standards in accordance with best practices from the North American Insulation Manufacturers Association (NAIMA) and Underwriters Laboratories (UL).

The Fibrous Glass Duct Construction Standards has been an industry resource for contractors since the first edition was published in 1992. First published in 1968, the manual has evolved to include industry innovations while providing contractors with the most updated information for fibrous glass duct installation and fabrication. The latest edition highlights new guidelines based on current practices with updates including the addition of application details for 1400 El 2” boards; revisions to tie rod reinforcement, channel system reinforcement, partial wrap-around reinforcement, and fasteners associated with the newer boards; and provisions for fittings, closures, and specifications as referenced by NAIMA and UL.

“�鶹��� continues to advance engineering and design standards for ductwork, resulting in cost-effective construction techniques, greater system efficiencies and improved indoor air quality for building occupants,” said Vince Sandusky, CEO of �鶹���. “In updating this standard to reflect current industry practices in the use and installation of Fibrous Glass Duct, �鶹��� helps ensure that all contractors operate under standardized industry procedures, including the use of specified materials and reinforcements in appropriate settings.”

Technical standards and manuals developed by �鶹��� members have worldwide acceptance by the construction and code community, as well as local and national government agencies. �鶹��� 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 – and advancements are made possible by those in the industry who provide suggestions for improvement based on knowledge, experience, and research.
