Thermoset FRP Duct Construction Manual

The second edition of the 'Thermoset FRP Duct Construction Manual' is now available. The 228-page book is an authoritative resource that design engineers, industrial engineering departments, pollution control authorities, FRP manufacturers, and installation contractors can rely upon for the proper selection, manufacture, and installation of FRP duct systems.
This American National Standard (ANSI/SMACNA 011-2017) contains language, tables, and details for the construction of hand lay-up, spray-up, and filament wound FRP ductwork from 30 inch wg negative pressure to 30 inch wg positive pressure. Round ductwork sizes are expanded to include up to 96 inches diameter. For rectangular ductwork, new duct stiffener tables are added for easier selection.
Recognizing the increased popularity of FRP ductwork, this expanded edition includes commercial/HVAC applications. Supporting this, an underground installation section is added as well as added language on testing and balancing, duct sealing, and duct leakage. Duct hangers and support information has been expanded and organized into a separate chapter which now includes: upper attachments, hanger selection tables, channel (strut) used as trapeze, riser support details, and more. Appendices cover: extended hanger spacing, general information on safe handling of thermoset fiberglass reinforced plastic duct, and allowable FRP defects.
