Keynote: Why Air Barrier Specialists Need to Understand Water

Tuesday, March 26, 3:00 – 5:00pm

It’s been said that the three biggest problems in buildings are water, water, and water. Moisture is involved in everything from rot to corrosion to buckling to bugs. But what does that have to do with air? In his keynote presentation, John Straube will take a closer look at different materials used to control air or water (or both!), and how material properties impact assembly design and performance, product specification, and inspection activities.

Learning Objectives:

  1. Recognize the differences and relationship between vapor, air, and thermal control.
  2. Understand key building science principles that determine how water vapor and liquid water move through materials and assemblies.
  3. Identify critical details and transitions that impact rain and air control.
  4. List common moisture-related problems and their impacts on buildings and building occupants.
