Bowie, MD 20715

4.5 HSW/LU CEU's

Air Barrier & Flashing Symposium

Co-hosted with: BEC-Baltimore, International Masonry Institute (IMI), Air Barrier Association of America (ABAA)


Building Enclosure Council (BEC)-DC, in conjunction with BEC-Baltimore, is hosting a symposium with in depth discussion and demonstration of air barrier and flashing integration for high-performing building enclosures. The event is jointly hosted by the International Masonry Institute (IMI) and the Air Barrier Association of America (ABAA) and will be located at IMI in Bowie, MD.

During the workshop, instructors will review four mock ups in conjunction with classroom presentations. Discussion will also focus on the installation of air and vapor barriers, flashings at openings and roofs, as well as critical tie-in details and transitions between each of the systems.

Please note that this is a warehouse/workshop facility, so appropriate dress is recommended. While hard hats are not required, PPE (i.e. gloves and safety glasses) will be provided by IMI. No scaffolding will be required for interaction with mock ups. Free parking and lunch provided.

Learning Objectives:

After attending this course, participants will be able to:

  • Explain the composition of different types of flashing and their effects on sustainability and life cycle costs;

  • Describe why the roof/wall air barrier intersection is critical to building performance in regards to moisture management, air leakage control, common design, and field errors;

  • Discuss critical aspects of design, based on building science principles, by using sample details for continuity, redundancy and certain code requirements of the air barrier system; and

  • Explain the various test methods for installation verification for both air and water performance by reviewing ASTM and AAMA test standards, how they are conducted, and when they should be conducted through examples and photos.

Only a limited amount of spots are available. Please click here​ to register and receive your CEU's.
