Polyguard Airlok Flex VP

Polyguard Airlok Flex VP

Air Barrier systems provide the only effective defense against air leakage and moisture issues. Polyguard's Airlok Flex® VP is a water-based, permeable, cold fluid-applied, single-component, acrylic-based, elastomeric membrane designed to prevent air and moisture penetration while allowing water vapor to escape.  Airlok Flex® VP is engineered as an air barrier for installation on concrete and concrete masonry (CMU), paper, glass or foil faced sheathing, plywood, oriented strand board (OSB) and rigid insulation in the cavity.  Airlok Flex® VP can be applied in a temperature range of 40° F up to 120° F. and is resistant to ultraviolet (UV). 



  • Superior UV resistance allows for use on both unexposed and exposed portions of walls
  • Can be applied in a temperature range of 40° F up to 120° F
  • Forms a tough, continuous bonded elastomeric barrier that provides protection against air infiltration and exfiltration to reduce energy loss
  • Proban® mold inhibitor can be added at the factory to provide additional contact mold-inhibiting properties to the air barrier system
