Building science tells us how buildings perform, especially with moisture movement. This presentation will help designers better understand how moisture moves through airflow by diffusion. We will discuss permeability of materials and its impact on the performance of enclosure assemblies. Strategies for detailing assemblies to meet both designer’s code-mandated responsibilities and airtightness testing requirements will be discussed, highlighted by project examples demonstrating the impact of different approaches on the moisture performance of the enclosure.
