Product Details
Thermaflex M-KE HVAC ducts feature a vinyl coated spring steel wire coil construction suitable for low to medium pressure heating and cooling environments. This highly efficient ducting system includes a core that is bonded to the steel wire coil, providing support for fiberglass insulation. The duct insulation is available in three different R-values for varied thickness: R-4.2, R-6.0, and R-8.0. The acoustically rated polyethylene inner liner effectively eliminates noise while allowing for easy expansion. Additionally, the spiral ducts are mold and mildew resistant, with a temperature range from -20°F to 200°F and -20°F to 250°F for intermittent use. The inner core is self-extinguishing, and the ducts are available in diameters ranging from 4 to 20 inches. These products are GREENGUARD certified and come with a 10-year limited warranty.
