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 2012 International Energy Code requirements for insulation exterior wall assemblies will be reviewed and critiqued. Live hygrothermal analyses will be run to show which insulation schemes work and which ones do not.
