Air Barriers in Metal Buildings
Air barriers are an integral part of energy code compliance for metal buildings. In fact, the two major energy codes in the United States, IECC and ASHRAE, both require metal buildings to have an air barrier, and for it to be indicated in drawings. However, much confusion remains about air barriers and their role in creating an airtight building envelope. This session gives attendees an introduction to air barriers in metal buildings, including a breakdown of air leakage and air infiltration in the building envelope. Presented by Bill Beals, District Manager of Therm-All, a 35-year veteran of the metal building industry and author of the bi-monthly commercial energy codes blog called “The Code Man.”
- Learn what an air barrier is, including its purpose in metal buildings, composition, placement within the building envelope, etc.
- Discover what the Air Barrier Standard is in the latest commercial energy code cycle (IECC 2021/ASHRAE 90.1-2019) and prior code cycles in which an air barrier is a mandatory component of the building envelope.
- Understand the basics of air leakage in the metal building envelope.
- Differentiate between an air barrier and a vapor retarder.
- Learn about the three compliance options for the Air Barrier Standard (assembly, whole building materials, assembly compliance option).
- Discover the benefits of an energy-efficient, airtight building envelope.
Registration includes access to all exhibits, education sessions on the show floor, keynotes and networking events.
