Insulation Solutions Viper II 10 mil Class A Vapor Barrier

Insulation Solutions Viper II Concrete Vapor Barrier, 10-Mil, 14′ x 210′ Roll, in Gray Color, Class A Viper VaporCheck II (Viper II) is the first line of defense against damaging water vapor and soil-gas threats existing below the concrete slab. Viper II products are multi-layer (co-extruded), virgin polyolefin under-slab vapor barriers/retarders. The virgin resin used to manufacture Viper II contributes to its long-term stability and prevents the material from breaking down when buried below the slab.

Viper II is engineered with superior resistance against punctures, tears and water vapor. The high-puncture resistance and tensile strength greatly reduces potential damage when exposed to rigorous job-site conditions. Furthermore, Viper II products have very low-water vapor permeance properties, key to preventing water-vapor migration.
