Product Details
Highly efficient, Thermaflex G-KM spiral ducts are premium air vessels designed 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 for support and is insulated with a thick fiberglass blanket. The ducts include a heavy-duty polyethylene vapor barrier that ensures even airflow and a double air seal, enhancing performance. They are self-extinguishing and will not support flames, making them compliant with safety standards. The temperature range is from -20°F to 250°F, with an intermittent range of -20°F to 250°F. The ducts are available in diameters ranging from 3 to 20 inches and are GREENGUARD certified. This product comes with a 10-year limited warranty.
