Adhesive-backed duct liner for thermal and acoustic applications

Duct liner is used primarily as acoustical liner in HVAC sheet metal ducts to absorb unwanted crosstalk, equipment and air movement noise. It also helps improve the energy-efficiency of the system by reducing heat gain or loss. In addition, duct liner helps minimize moisture problems due to condensation.

At Canada Rubber Group Inc. (CRGI), we produce adhesive-backed duct liner for HVAC applications. In producing the finished product, we laminate on to the duct liner a pressure-sensitive adhesive backing. The adhesive backing greatly simplifies installation and keeps the liner in place once installed.

Duct liner we can supply includes that made from rotary spun glass fibers as well as that made from closed cell elastomeric sponge. Both types offer very high acoustical and thermal performance. Advantages of the duct liner materials we can supply include the following:

Adhesive-backed duct liner supplied by CRGI has application in HVAC systems, sheet metal ductwork, plenums, fan housings, mixing boxes, and furnaces. We can supply adhesive-backed duct liner in various widths, sized to customer requirements.
