Thermaflex M Ke Hvac ducts have a vinyl coated spring steel wire coil construction that is ideal for low medium pressure heating and cooling environments.
These highly efficient flex ducts feature a core that is bonded to the steel wire coil to support the fiberglass insulation. 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 on these Hvac ducts eliminates noise and easily expands. Spiral ducts are mold and mildew resistant. Temperature range is from 20f to 200f and 20f to 250f intermittent. Inner core is self extinguishing. Ducts measure 4 20" in diameter. Greenguard certified. 10 Year Limited Warranty.
