ToughGard™ R with Enhanced Surface duct liner now offers a more moisture-resistant surface, up to 40% more moisture protection than previous models. It preserves the sound-dampening performance of the duct liner by a--llowing sound waves to pass through the open cell struct-ure and into the sound absorbing glass fiber mat. It also has an EPA-registered anti-microbial to combat mold growth. A tougher airstream surface resists tearing, puncturing ands other surface wear.
