Product Details
K-Flex Duct™ Liner Gray S2S 1 X 60 X 50' is an environmentally friendly, CFC and HCFC-free, closed-cell, flexible elastomeric thermal and acoustical insulation designed to retard heat gain and prevent condensation or frost formation on cold equipment or ducts. This product also effectively retards heat loss when applied to hot equipment or ducts, functioning as both a duct and air handling equipment liner. The thickness has been specifically calculated to control condensation on cold surfaces while the closed-cell structure and unique formulation provide low transmittance vapor retarder capabilities, often requiring no additional protection for most applications. The product complies with specifications including ASTM C534 Type 2 (sheet), Grade 1, ASTM D1056-00-2C1, ASTM C423/E795 with an NRC of 0.50 at 1 thickness, and meets New York City MEA 186-86-M Vol. IV and USDA requirements. It has a UL 94-5V flammability classification (recognition No. E300774) and conforms to ASTM E 84 foam core ratings of 25/50 at 2 and below, with PSA ratings of 0/10. Additionally, it meets NFPA 90A Sect. 2.3.3 requirements for supplementary materials for air distribution systems up to 1 thickness and adheres to UL 181 sections 11.0 and 16.0 for mold growth and air erosion. This product is sold in a package quantity of 1 and is priced each.
