Air and water-restive barriers are critical control layers in all buildings and their importance is growing as we move to high performance buildings. Buildings contain many materials that meet the criteria of a air barrier materials but unless those materials have been designed and installed properly, you do not have an air barrier system.

The number of air and water-restive barrier materials have grown exponentially over the last two decades. People ask what is the best air barrier material to use and there is no single answer to that question. Installation of any air barrier material will not perform as intended if they are not installed correctly.

This presentation covers the requirements for installing the different types of barriers and lists the common problems seen on the jobsites.

Learning Objectives:
- Show why a proper installation starts with a good design
- List the four requirements for a substrate
- Determine proper installation by material type
- Identify a means of ensuring a quality installation
- Discover components that make up the air and water resistive barriers
