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. The core is bonded to a steel wire coil, providing support for the thick fiberglass insulation blanket. These air ducts also include a heavy-duty polyethylene vapor barrier that ensures even airflow and incorporates a double air seal. They are self-extinguishing and will not support flames, with a temperature range of -20°F to 250°F and -20°F to 250°F intermittent. Ducts are available in diameters ranging from 3 to 20 inches. Additionally, they are Greenguard certified and come with a 10-year limited warranty.
