16" X 25' Flexible Ductwork R6 Insulated

R6 INSULATED FLEXIBLE DUCT 16" X 25' Our air duct is a thermally insulated , fully lined, flexible air duct designed for use in all medium pressure cooling and heating systems. It is used in either supply or return sections: for branch ducts and branch connections to or between mixing units, induction units, control or terminal units and diffusion devices, including light troffers. • Underwriters Laboratories UL 181 listed, and complies with NFPA Standards 90A and 90B. • Core material will not support mold and mildew growth. • Fully lined for efficient air delivery. • Large diameter, heavy, spring steel wire helix assures dimensional stability, resists mechanical abuse and provides more efficient air delivery. • Bi-Directional reinforced metallized jacket resists tearing— reduces chance for damage to vapor barrier. • Acoustically rated CPE core assures quiet performance. • Uniquely constructed core will not unravel when cut. • All components are self-extinguishing and will not support flame (see oxygen index figures under application and engineering data). • “Outward Cast” of heavy spring steel helix keeps duct core from shrinking up inside insulation and jacket, resulting in less waste. • CPE core material will stretch over fittings providing a “snug” fit and reducing labor costs associated with a poor fit. • CPE core will not “blow-out” and eliminates costly call-backs. • Labor savings and reduced waste result in lower installed costs.
