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. These efficient flex ducts include a core that is bonded to the steel wire coil to support fiberglass insulation, with insulation available in three different R-values: R-4.2, R-6.0, and R-8.0. The polyethylene inner liner is acoustically rated, effectively eliminating noise while allowing for easy expansion. Additionally, the spiral ducts are resistant to mold and mildew, with a temperature range of -20F to 200F and an intermittent range of -20F to 250F. The inner core is self-extinguishing, and the ducts have a diameter range of 4 to 20 inches. These products are GREENGUARD certified and come with a 10-year limited warranty.
