Highly efficient, Thermaflex G-KM spiral ducts are premium air vessels for low to medium pressure heating and cooling systems. These acoustically rated HVAC ducts eliminate noise and feature a core that easily expands over fittings. The core is bonded to a steel wire coil to support a thick fiberglass insulation blanket. These air ducts are equipped with a heavy-duty polyethylene vapor barrier that ensures even airflow and a double air seal. They are self-extinguishing and will not support flames. The temperature range for these ducts is from -20°F to 250°F and -20°F to 250°F intermittent, with diameters ranging from 3 inches to 20 inches. The ducts are Greenguard certified and come with a 10-year limited warranty.
