Design Considerations For Air Barriers


As follow up to the Four Barriers For Four Wetting Potentials presentation, this presentation focuses on design considerations for air barrier systems. Products and systems are reviewed and critiqued. Ancillary building enclosure system components are discussed. Problematic areas of the building enclosure system are brought to attention.

The goal of the presentation is to point out critical considerations that should be addressed prior to commencing with the working drawings for a project.

Why should you Attend: Moisture related problems in building exterior walls are the most common causes of litigation in the construction industry. Advances in building science and analysis now offer building professionals the knowledge and insight on how to design effective exterior wall assemblies that do not experience these problems. Knowing building science basics and the tools used to properly analyze exterior wall performance will lead to effective exterior walls for designers, owners and contractors.

Areas Covered in the Session: Learn about the products that can be used for creating the four barriers for the four wetting potentials and how to effectively integrate them into exterior wall design and construction. This presentation focuses on the air barrier and the other barrier functions that it can provide in the exterior wall assembly.

Who Will Benefit:

  • Architects
  • Consultants
  • Building owners
  • Contractors
