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, which provides support to the thick fiberglass insulation blanket. Additionally, these air ducts are equipped with a heavy-duty polyethylene vapor barrier that ensures even airflow and a double air seal. They are self-extinguishing and will not support flames. The temperature range for these ducts is from -20°F to 250°F, with intermittent use also rated from -20°F to 250°F. The ducts come with a diameter range of 3-20 inches and are GREENGUARD certified, backed by a 10-year limited warranty.
