This presentation focuses on the one building envelope system component that has the potential to be the most detrimental to the air barrier system. The installation of masonry veneer anchors creates, by far, the most penetrations in the air barrier system. Leaks that can occur due to improper anchor selection, installation and sequencing have the most potential to render the air barrier system ineffective. Requirements for masonry veneer anchors used with air barrier systems are reviewed. The various anchor systems currently available on the market are exhibited and critiqued. Finally, testing and inspections methods and protocols are offered to insure an effective air barrier system.
