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