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 contain a core that easily expands over fittings. The core is bonded to a steel wire coil for structural support, while the thick fiberglass insulation blanket enhances thermal performance. Additionally, the ducts are equipped with a heavy-duty polyethylene vapor barrier to ensure even airflow and feature a double air seal. They are self-extinguishing and will not support flames, operating within a temperature range of -20°F to 250°F, with an intermittent range of -20°F to 250°F. Available in diameters ranging from 3 to 20 inches, these ducts are GREENGUARD certified and come with a 10-year limited warranty.
