Fluid-applied air and water barrier products have rapidly gained market share in many areas of the country, but they are still relatively new to the industry. It is perhaps unsurprising then that various failures of these products have been seen during their installation.
Two critical aspects of sustainable construction are long-term durability and energy efficiency. The latter is a measure of whole building performance, which depends on the envelope as well as the building systems and occupant behavior.
Providing adequate rainwater management and control for air, vapor, and heat flow through the building enclosure is critical to long-term performance and durability. In contemporary wall assemblies with layered materials, the complexity of coordinating these various demands can be overwhelming.
