Product Details
Highly efficient, Thermaflex G-KM spiral ducts are premium air vessels designed for low to medium pressure heating and cooling systems. The ducts are acoustically rated and engineered to eliminate noise, featuring a core that easily expands over fittings, which is bonded to a steel wire coil for enhanced support of the thick fiberglass insulation blanket. Each duct includes a heavy-duty polyethylene vapor barrier for consistent airflow and a double air seal, ensuring optimal performance. These air ducts are self-extinguishing, meaning they won't support flames, and they operate within a temperature range of -20°F to 250°F with intermittent capability up to 250°F. The ducts are available in diameters ranging from 3 inches to 20 inches and are Greenguard certified, providing assurance of low chemical emissions. The product comes with a 10-year limited warranty, reflecting its durability and quality.
