THERMAFLEX® Flexible Air Duct, 25 ft Length, 12 in Diameter, 4 in-WC, 6 in-WC, Cross-Linked Polyethylene/Fiberglass, R-Value: R4.2, R8, 5000 fpm Velocity Rating, -20 to 200 deg F, -20 to 250 deg F, 0.1 Vapor Transmission
Highly-efficient, thermally insulated flexible duct for use in low and medium pressure heating and cooling systems. Acoustically rated, self-extinguishing cross linked polyethylene core easily expands over fittings. Core is permanently bonded to a coated spring steel wire helix that supports an ample blanket of fiberglass insulation over a fiberglass scrim and a tough polyethylene vapor barrier. Smooth liner, insulation and tough vapor barrier provide even airflow and a double air seal.
