Non-Permeable Air Barriers

Henry/Bakor Non-Permeable Air Barrier membranes act as air barriers, vapor barriers and rain barriers. They have been tested to resist air leakage (ASTM E 2178 and ASTM 2357), have very low vapor permeance (less than 0.1 perms) and are watertight. Since they also function as vapor barriers their position within the wall assembly should be verified to prevent moisture condensation.

Depending on the application, you will want either a fluid-applied or sheet-applied membrane. Use the tabs below to view the products within each category, and find your Henry/Bakor air barrier solution.
