ToughGard® Ultra*Round™ Spiral Duct Liner
ToughGard® Ultra*Round™ is acoustical and thermal insulation for lining the interior of spiral and round sheet metal ducts and plenums in HVAC systems. For increased performance, ToughGard® Ultra*Round™ reduces heat gain or loss while absorbing unwanted crosstalk, equipment and air rush noise. This acoustical and thermal insulation is designed specifically to line the interior of spiral and round sheet metal ducts and plenums in HVAC systems. Fabrication and installation is simplified in the shop or on the job and may eliminate the need for pins and adhesives in most straight duct sections. Compared to double wall systems, ToughGard Ultra*Round installation costs are lower, weight is reduced and acoustical performance is improved.
