    The ToughGard Ultra*Round Duct Liner delivers acoustical, thermal, and moisture control performance in spiral duct applications.

    Ultra*Round is overlaid with a tough and durable fire-resistant black composite air stream surface, which eliminates the cost of perforated metal lining in double-wall construction.
