Live webinar sponsored by the Air Barrier Association of America

This course defines and explains building science behind the code for the four control layers of the building envelope: water, air, thermal, and vapor. Special discussion will be had on air leakage, why it matters and why air barrier continuity is critical to building performance. Participants will then explore typical design principles as well as alternative system assembly approaches to exterior wall design. In addition, presentation covers common attachment strategies for various types of insulation, claddings, including masonry, rainscreen veneers, and applied/adhered veneers as well as how system testing can ensure air and water testing in the completed assembly.

Learning Objectives:

1. Learn the definition, code requirements and building science of control layers.
2. Outline typical design of control layers in exterior walls.
3. Understand critical interfaces for control layers within the building envelope – and common approaches to detailing.
4. Understand ways to evaluate systems to obtain durable interface performance.
