Selection of Air Barrier Membranes – What to Consider
Track 2: Design Professionals
Wednesday, March 27, 1:00 – 2:00pm
Air barrier membranes have become a common component in modern construction. However, there are a variety of options, differing in method of installation as well as performance properties. This presentation focuses on some of the selection criteria that should be considered when determining which air barrier membrane should be used for your project, focusing on installation methods and basic properties. Additionally, the presentation will review several “rules of thumb” such as minimum mil thickness, vapor retarder location, and material compatibility that are often misconstrued. Lastly, the presentation will touch on the importance of evaluating air barrier properties in the context of the material properties of the overall wall assembly.
- Participants will be able to identify recent Code changes that should be considered when selecting air barrier membranes.
- Participants will be able to identify common building conditions that should be considered when determining the air barrier materials for a project.
- Participants will be able to examine components of wall assemblies to identify material properties that should be considered when evaluating air barrier properties.
- Participants will be able to analyze material properties of air barrier membranes to determine important characteristics that should be included in Project Specifications.
