Vapor Barrier Retarders are composed of high performance polyolefin resins to create a highly puncture resistant vapor barrier for use under concrete slabs or in the building envelope to stop moisture migration and reduce mold, mildew, and fungus. Americover’s vapor barriers meet or exceed ASTM 1745, Class A, B, and C standards for water vapor retarders used in contact with soil or granular fill under concrete slabs.
Vapor Barrier Retarders are available in 10, 15, and 20 mil thicknesses. Color options include blue and yellow.
