PERM-A-BARRIER LIQUID
Perm-A-Barrier® Liquid is a two component, synthetic rubber, cold-vulcanized, fluid applied air and vapor barrier membrane. It cures to form a resilient, monolithic, fully bonded elastomeric sheet, protecting above grade wall assemblies against the damaging effects of air, vapor and water ingress. Perm-A-Barrier Liquid provides an effective barrier against air infiltration and exfiltration while minimizing the associated energy loss and condensation problems and its versatility makes it easy to use in detailed areas.
