Permeable vs. Non-Permeable Air Barriers – Which Decision Is Best? (Virtual AIA)

Permeable vs. Non-Permeable Air Barriers – Which Decision Is Best?
Host: Peter Weeks

This course helps designers evaluate when to use permeable or non-water-vapor-permeable air barriers in exterior wall assemblies. It covers key terminology, specification language, applicable building code considerations, the risks of creating a “double vapor barrier,” and the importance of designing wall systems with appropriate drying potential. The program is AIA/CES registered, HSW-approved, and qualifies for one learning unit (LU).
