Basic Use: ToughGard® R-EP Duct Liner with Enhanced Surface is used primarily as an acoustical liner in HVAC sheet metal ducts to absorb unwanted crosstalk, equipment and air rush noise. This product can be used 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). ToughGard® R-EP with Enhanced Surface provides superior thermal and acoustical properties compared to other duct liners of the same thickness, making it the ideal choice for applications that demand enhanced performance.

Benefits: ToughGard® R-EP Duct Liner with Enhanced Surface is 40% more water repellent than standard duct liner. This product provides excellent thermal properties, exhibits low air flow resistance and meets applicable fire resistance standards and building code requirements. It is durable, easy-to clean and has a factory-applied edge coating that assures sealing of the transverse edges as per SMACNA and NAIMA Installation Standards.
