The ToughGard® 2 textile duct liner has been renamed ToughGard® T. The duct liner now features an aesthetically pleasing, deep, rich black fiberglass mat, says the manufacturer. Used primarily as an acoustical liner in HVAC sheet metal ducts, the duct liner helps improve the energy efficiency of a HVAC system by reducing heat gain or loss and minimizes moisture problems due to condensation. Composed primarily of long, textile-type glass fibers, the duct liner is a durable, abuse-resistant, and easy-to-clean product. Moisture that enters a duct system insulated with ToughGard T textile duct liner beads up and stays beaded, allowing airflow to evaporate the moisture before it can be absorbed into the liner, the company says. The liner includes 75 percent recycled content.
