Building Envelope Tech Team Meeting: Addressing Air Leakage

Air barrier solutions, like sealants, membranes, spray foams, and sheathings, are key to addressing air leakage in commercial buildings, which can account for about 20 percent of the total energy used to heat and cool buildings. During this Building Envelope Tech Team Meeting, the team discussed current practices in measuring air leakage and explored technical resources to support application of advanced air barrier technologies.
