Learning Objectives:

  1. Determine the key reason for installing an air barrier system.
  2. Explain why you need to know more about a material than just the air leakage rate.
  3. Show why a visual inspection is not enough for an air barrier system.
  4. Demonstrate how an air barrier system impacts all parts of the building.



Air barrier systems encompass all six sides of a building. Understanding the functions of the materials used as air- and water-resistive barriers is critical to properly specifying an air barrier system in project specifications. More is needed than simply inserting a material from a manufacturer. This presentation walks you through the process and guides you in developing a project specification for an air barrier system.
