While the quest for increased R-values has led to dramatic reductions in air movement through building assemblies, it has also reduced their ability to dry when they get wet. In-wall systems allow this moisture to dissipate while maintaining the desired degree of airtightness. One way to create moisture escape routes is through construction techniques. Another is through the use of products that employ advanced air/moisture barrier technology.
High-performance buildings are constructed to maximize energy efficiency, durability and overall occupant comfort. As the demand for these buildings continues to increase, it is important to understand that one of the key aspects of achieving this is proper building enclosure design and overall wall system performance.
