Product Details
Thermaflex M-KE HVAC ducts are constructed with a vinyl coated spring steel wire coil, making them suitable for low to medium pressure heating and cooling environments. The ducts include a bonded core to the steel wire coil that supports fiberglass insulation and are available with three different R-values: R-4.2, R-6.0, and R-8.0, providing varied thickness options. Equipped with an acoustically rated polyethylene inner liner, these ducts effectively eliminate noise and allow for easy expansion. The spiral ducts are resistant to mold and mildew, with a temperature range of -20°F to 200°F and -20°F to 250°F for intermittent use. The inner core is self-extinguishing, and the ducts come in diameters ranging from 4 to 20 inches. Additionally, they are Greenguard certified and include a 10-year limited warranty.
