The most common source of building enclosure failure is moisture and the consequences range from a visible, isolated water leak to widespread concealed deterioration, corrosion, and mold growth. Contemporary building enclosures are essentially an assembly of barriers that, in combination, control moisture migration and condensation. The enclosure’s performance in this regard depends on proper sequencing, detailing, and construction of essential barriers designed to control the flow of water, heat, air, and vapor.
