SMACNA Introduces First Phenolic Duct Construction Standard

May 05, 2015

CHANTILLY, VA—SMACNA’s first edition of the “Phenolic Duct Construction Standard” provides basic phenolic duct fabrication and installation standards that sheet metal contractors, code officials and design engineers will find useful. It is a new American National Standard.

This new 144-page standard for phenolic air distribution system material provides for the basic fabrication and installation methods. It applies to ducts up to 80” x 80” that operate to 4” wg positive or 3” negative pressure class.

The new publication includes model project specifications, duct performance characteristics, specifications and closures, fittings and connections, reinforcement, hangers and support, accessories, and an inspection checklist.

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 leverage these features by manufacturing the insulation into rigid panels with aluminum facings on both sides of the panel.
