K-Flex Duct Liner Gray provides excellent thermal and acoustical properties. Specifically, it provides noise reduction (NRC of .50 at 1″ thickness) properties that outperform fiberglass in sound absorption coefficient values at frequencies below 500 Hz, energy conservation (R-4.2 at 1″ thickness and R-8 at 2″ thickness), and IAQ control (closed-cell structure prevents moisture intrusion and subsequent mold growth).
Recommended for applications ranging from -40°F to 200°F, the product is available in a range of widths (46″ to 60″) and thicknesses (1/2″ to 2″).
K-Flex Duct Liner Gray is non-porous, fiber-free and prevents mold, fungal and bacterial growth. For added protection, K-Flex Duct® Liner Gray is protected with an EPA-approved antimicrobial agent. K-Flex Duct® Liner Gray is GREENGUARD® certified under the Children and Schools and Microbial Resistance classifications , and meets the 25/50 flame spread and smoke development rating up to 2” thickness according to ASTM E-84 standards.
