"K-Flex" LS aluminum-backed sheet eliminates the extra step and cost of painting insulation with two or three layers to protect it from the elements. Its closed-cell, non-fibrous structure does not adsorb moisture, and K-Flex is free of chlorofluorocarbons. Rolls are available in 3- by 4-foot sheets, up to 2 inches thick.
