Viper II Platinum is an under-slab vapor retarder specifically designed for preventing moisture migration through concrete slabs-on-grade. Viper II Platinum is the first of its kind able to achieve ASTM E 1745 Class A status for blown films under 10-mils thick. Viper II Platinum reduces water vapor emission transfer and moisture migration from entering the building envelope on commercial, industrial and residential applications. Viper II Platinum controls condensation, mold, mildew, degradation and prevents costly flooring failures and damage to moisture sensitive furnishings within a building’s interior. Viper II Platinum may be used to reduce radon and methane gas migration and is resistant to other adverse soil conditions. BENEFITS Manufactured using seven-layer co-extrusion technology from virgin resin Maintains long-term performance after exposure to adverse soil condition Exceeds ASTM E 1745 “Class A” guidelines High puncture and tensile strength Greatly reduces moisture migration through slab-on-grade applications
