VaporBlock Plus® Series (VBP20)

VaporBlock® PLUS™ Series consists of seven-layer co-extruded barriers made from state-of-the-art polyethylene and EVOH resins to provide unmatched impact strength as well as superior resistance to gas and moisture transmission. VaporBlock Plus is a highly resilient under slab and wall barrier designed to restrict naturally occurring gases from migrating through the ground and concrete slab. It is more than 100 times less permeable than typical high-performance polyethylene vapor retarders against Methane, Radon and other harmful VOCs.

Benefits

  • Exceeds ASTM E-1745 class A, B and C requirements
  • Superior puncture resistance
  • Resistance to decay and degradation
