Create healthy, sustainable building interiors with Greenguard-certified ToughGard R-EP Duct Liner with Enhanced Surface from CertainTeed. The duct liner provides acoustical and thermal control and anti-microbial protection in duct systems. The duct liner is composed of rotary-type glass fibers firmly bonded with a thermosetting resin overlaid with durable, fire-resistant black composite surface on the steam side. It absorbs unwanted crosstalk, equipment, and air rush noise, and minimizes heat and cooled air loss. ToughGard R-EP is 40% more water repellent than standard duct liner and its airstream surface contains a U.S. EPA-registered anti-microbial agent.
