WHITECAP WOVEN 12 MIL LINER | 4’x 200’ 800 SQ FT | 12’x 100’ 1000 SQ FT

Looking for a durable yet extremely lightweight material for your crawl space vapor barrier projects? The 12 MIL LINER has more than double the puncture resistance of comparable string reinforced liners. It’s also been lab-tested, detailing better moisture blocking abilities and protection against the soil gases that can lead to unpleasant crawl space odors and poor indoor air quality. WhiteCap 12 MIL LINER vapor barriers are surprisingly pliable and show few wrinkles when installed.
