Vapor barriers are often required in colder climates to help prevent condensation on the backside of our sheathing, but did you know that a standard polyethylene vapor barrier can actually trap moisture within the assembly? This has led to a lot of mold and rot remediations, as our buildings need the ability to dry if they get wet. Buildings can get wet from rainwater penetration, plumbing leaks, capillary transfer of water, and air leaks, and we need to allow this moisture to be able to dry out. This is where we recommend making a shift to smart vapor retarder membranes instead of the standard polyethylene. Smart vapor retarder membranes increase in permeance when conditions are damp or humid, preventing moisture from being trapped within the assembly.
