Sheet Metal and Air Conditioning Contractors' National Association (SMACNA) recently announced the publication of the first edition of its Phenolic Duct Construction Standard.

An American National Standard, the 144-page Phenolic Duct Construction Standard applies to ducts up to 80 in. by 80 in. that operate to 4 in. wg positive or 3 in. negative pressure.

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

For architectural and engineering firms not in the contracting business, government agencies, schools, and libraries, the costs are $110 for the book, $132 for the CD, $182 for the book/CD combination, and $110 for the PDF.
