This is the First Edition of the SMACNA Phenolic Duct Construction Standard. It is intended to provide basic phenolic duct fabrication and installation standards to the industry.
Phenolic foam insulation is a versatile material with high thermal performance, moisture resistance, fire performance, and structural strength. Phenolic panels used for air distribution ductwork leverages these features by manufacturing the insulation into rigid panels with aluminum facings on both sides of the panel. The resulting ductwork is durable, pre- insulated, light weight, energy efficient, and low leak.
SMACNA thanks the SMACNA contractors who, as members of the Phenolic Duct Construction Task Force, volunteered their time and effort to the development of this manual. SMACNA appreciates their dedication and willingness to share their knowledge and experience in the fabrication and installation of Phenolic Duct systems.
