Duct liner is used primarily as acoustical liner in HVAC sheet metal ducts to absorb unwanted crosstalk, equipment and air rush noise. It also helps improve the energy-efficiency of the system by reducing heat gain or loss. Plus, duct liner helps minimize moisture problems due to condensation.
Composed primarily of long, textile-type glass fibers firmly bonded together with a thermosetting resin and overlaid with an extremely tough and durable fire-resistant black composite air stream surface.
Duct liner products perform in most types of heating and cooling duct systems, operating at velocities up to 6,000 fpm (30.5 m/s) and temperatures to 250°F (121°C).
Duct liner products regularly meet the requirements of the following current specifications, standards and codes:
