Four Barriers For Four Wetting Potentials: How To Design Effective Exterior Wall Systems

May 6 @ 1:00 PM - 2:00 PM

Live webinar sponsored by the Air Barrier Association of America

 

This presentation looks at the four wetting potentials that exterior wall assemblies are exposed to due to the climatic difference between the interior and exterior environment. The four barriers needed to effectively separate the two environments and not create moisture problems are identified. The science and physics behind the inclusion and location of these barriers will be discussed. Various exterior wall assemblies will be reviewed and critiqued. The 2018 International Energy Code requirements for insulation exterior wall assemblies will be reviewed and critiqued. Live hygrothermal analyses will be run to show which building enclosure assemblies work and which ones do not based on the assembly, the climate and the interior conditions.

 

Learning Objectives:

  1. Learn the four wetting potentials that aq building enclosure is exposed to.
  2. Learn basic building science and physics.
  3. Learn the four barriers needed to protect the building from the four wetting potentials.
  4. Learn how to properly integrate the four barriers into the building enclosure assembly.
