Product Details
Highly efficient, Thermaflex G-KM spiral ducts are premium air vessels for low and 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 air ducts feature 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 have a diameter ranging from 3 to 20 inches and are GREENGUARD certified. The product also comes with a 10-year limited warranty.
