ALEXANDRIA, Va. — The North American Insulation Manufacturers Association (NAIMA) has announced the release of a new instructional training series DVD on fabricating fiberglass duct board systems. Based on NAIMA’s Fibrous Glass Duct Construction Standard, the DVD includes 22 short video demonstrations on the latest duct board fabrication techniques. Demonstrations include how to construct simple straight duct sections; how to use a grooving machine to make straight ducts the easy way; and how to utilize the modular duct construction method to make fittings easier, stronger, faster and less costly to fabricate than the same type of sheet metal fitting.

Developed for both new and experienced HVAC contractors and technicians, the training sessions cover tools, fabrication techniques, and the methodology behind ducts and fittings typically used on today’s HVAC systems. Beginning with the basics, the training series includes timesaving tools and tips, duct reinforcement for larger duct systems, and proper duct closure systems — one of the most critical parts of the fabrication process.
