Exterior Air Barrier Research for Highly Insulated Deep Wall Assemblies in Cold Climates
Description The purpose of this study is to investigate the amount of moisture that is transported within a deep wall assembly through the process of natural convective air movement when an exterior air barrier is used. Measurements will be collected to validate the hygrothermal model to provide long-term behavior under various climate scenarios. The influence of cavity insulation material properties will also be investigated. Impact This research supports informed considerations when designing buildings to ensure long-term high performance and durability, as well as the health and safety of the occupants. The study will also help to identify buildable solutions for Step 5 Energy Code compliance in cold climates.
