PERMINATOR underslab vapor mat from W. R. MEADOWS is a new generation of polyolefin-based resin/chemical technology. PERMINATOR provides the vapor barrier industry with a highly effective, economical choice for helping to reduce the penetration of moisture and water vapor through the slab into the structure, thereby helping to reduce fungus, mildew and mold growth. PERMINATOR also helps reduce radon gas from entering the structure. PERMINATOR is tough enough to withstand normal construction jobsite conditions and traffic. It will not crack, puncture, snag, split or tear easily. PERMINATOR helps meet and maintain the maximum slab moisture transfer rate of 3 lbs/1000 sq. ft./24 hours, as allowed by the flooring industry’s specifications. PERMINATOR is available in 15 mil and 10 mil thicknesses. Both versions are furnished in 200-foot (61 m) long rolls. PERMINATOR meets or exceeds all requirements of ASTM E 1745 Classes A, B & C.
