Air Barrier Fundamentals – The Why and What of Building Airtightness
Tuesday May 6, 10:00am – 11:00am
Centennial D
This foundational program will dive into why we are concerned about building airtightness and how air barriers impact all other components within the wall assembly. Once you have a good understanding of the “why”, you appreciate how important these materials are and how the proper installation can have a huge impact on its performance and the ultimate success of any building. It’s not just about air, it’s about water too! We sometimes forget that an air barrier usually, if not all the time, does more than one thing.
Although boring to read, it is important to know building code requirements, along with what constitutes an air barrier material or system. Did you know that Peanut Butter can be an air barrier! Well, maybe it isn’t, but it could be…. Are you intrigued?
Learning Objectives:
- Describe the benefits or air barriers and the impacts on energy, moisture, sustainability and comfort
- Understand Air Barriers in relation to the building enclosure
- List performance requirements of Air Barrier materials, assemblies and systems
- Understand building code requirements and gain knowledge in market forces driving energy efficient buildings
