The e-book, Sealing the Building Envelope, focuses on permeability, and how to effectively manage moisture in building envelopes. This curated collection of technical articles from The Construction Specifier illustrates:

• gypsum-integrated water-resistive barrier-air barrier (WRB-AB) sheathings help balance an architect’s aesthetic preferences and air and moisture management of a building envelope;
• while stucco is a suitable choice for cladding, improper installation will lead to moisture infiltration; and
• designs permitting a continuous vapor/air barrier from the wall to the roof should be utilized in wood-framed, non-ventilated roof assemblies in northern climates to avoid dangerous and costly failures.
