McGill AirFlow's double-wall, insulated duct and fittings provide exceptional noise and thermal control in air handling systems. They are constructed of a solid sheet metal outer pressure shell and a sheet metal inner liner with a layer of insulation sandwiched between. We offer double-wall, round duct in three outer shell constructions: spiral lockseam, spiral lockseam with a standing rib, and longitudinal seam. Double-wall, flat oval duct is available in spiral lockseam and longitudinal seam constructions. View chart of McGill AirFlow's Duct and Fitting Construction Methods. Our standard double-wall duct and fittings have galvanized sheet metal outer walls and a layer of fiberglass insulation surrounding the inner liner.
