Vapor-Permeable Air Barrriers

vapor permeable barriers Henry/Bakor vapor-permeable air barrier membranes are air-tight and watertight. However, they are highly vapor permeable and typically can be positioned anywhere in the wall assembly for great design flexibility. Depending on the application, you will want either a fluid-applied or sheet-applied membrane.
