The YCS 14 MIL serves as the “do it all” product in the 100% YCS woven line. It stands up in nearly any crawl space project and is a great option for both piers and basement walls. The product comes white on both sides and provides a clean, bright finish. While all YCS vapor barriers are naturally resistant to mold growth, the 14 MIL contains an antimicrobial additive in the coating for an added layer of protection.
