Thursday, July 20, 2023 – 12 PM – 1:00 PM CST
Host: Scott Wolff

Information presented will assist designers in determining whether to use permeable or non-water-vapor-permeable air barriers. Attendees will gain knowledge of correct terminology, definitions and specification language per CSI MasterFormat, International Building Code (“Code”) and other sources. One key discussion item is avoidance of the “double vapor barrier” condition. Attendees will learn the importance of designing exterior walls with optimum drying potential. Reference to technical articles by noted building science professionals and organizations are identified as important tools in the quest for using permeable or non-permeable air barriers.
