Product Details
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 the thick fiberglass insulation blanket. These ducts include a heavy-duty polyethylene vapor barrier that provides even airflow and a double air seal. They are self-extinguishing and won't support flames. The temperature range is from -20°F to 250°F, with an intermittent range of -20°F to 250°F. Ducts are available in diameters from 3 to 20 inches and are GREENGUARD certified. They come with a 10-year limited warranty.
