Air Barriers 103: Avoiding Pitfalls with Air Barrier

Presented by Len Anastasi


With the proliferation of the use of air barriers in building enclosure systems the potential for problems exists in the industry. This workshop will review the proper planning, product selection, specifications, details and field quality assurance needed for a successful air barrier installation. The program starts with a list of steps to be taken during each phase of design and construction. Proper exterior wall design based on type of construction and proper material selection based on type of construction will then be reviewed. Details for specific wall construction type and product selection will be then be offered and reviewed. Poor detail examples will also be reviewed and discussed. Finally, quality assurance guidelines will be offered including pre-construction meetings, mock-up review and field inspection recommendations. Examples of problem installations will also be offered with explanations of the problems.


Learning Objectives:

  1. Review the four barriers needed for an effective exterior walls
  2. Learn what can happen when all four barriers are not included
  3. Learn what happens when the wrong materials are selected for even one of the barriers.
  4. Learn to design effective exterior walls based on building use and location of the building.
