Perminator is a premium underslab vapor barrier. This 15 mil barrier is a very effective choice to reduce the penetration of moisture and water vapor through the slap of the structure. This helps to reduce the growth of fungus, mildew, and mold growth. This product also helps to reduce radon gas from entering the structure. Perminator has one of the industry's lowest permeability ratings and nearly twice the puncture resistance of others.

***Minimum Order: 12 rolls*** Please call us at 800-583-4891 if you need less than this amount. We sell a comparable vapor barrier with no minimum order requirement.
