The SMACNA Fibrous Glass Duct Construction Standards is the authoritative technical manual for the design, fabrication, and installation of rigid fibrous glass duct systems in commercial and residential HVAC applications. Published by the Sheet Metal and Air Conditioning Contractors' National Association (SMACNA), this volume establishes field-tested performance standards for air closure systems, duct reinforcement, hanger supports, and fitting fabrication. It serves as an essential reference for mechanical contractors, sheet metal fabricators, duct installers, and candidates preparing for state trade licensing examinations.
