K-Flex duct liner gray is elastomeric, closed-cell insulation specially designed as a fiber-free alternative to lining air handling units and ducts. A uniquely tough skin surface is easy-to-clean and functional, providing an ideal surface to resist moisture and dirt. The double sided skin can be used with either side facing away from the applied surface, resulting in less waste if one side becomes damaged. K-Flex duct liner gray provides excellent thermal and acoustical properties. Specifically, it provides noise reduction (NRC of 0.5 at 1 in thickness) properties that outperform fiberglass in sound absorption coefficient values at frequencies below 500 Hz, energy conservation (R-4.2 at 1 in thickness and R-8 at 2 in thickness), and IAQ control (closed-cell structure prevents moisture intrusion and subsequent mold growth).
