This ducting is thermally insulated, fully lined, and flexible, designed for use in low to medium pressure ventilating, heating, and cooling systems. It is used in either supply or return sections: for branch ducts and branch connections. It is a highly efficient part of the total duct system because the smooth liner, the ample insulation and tough vapor barrier provide good air flow with positive thermal and acoustic insulation. And the ducting is GreenGuard Certified.
