Protecting Against Water Intrusion is a four-part e-book providing insight on the function and design of air and water control layers in modern, high-performance building enclosures, with an emphasis on the effect of penetrations and cladding attachment systems.
Guidelines for detailing and testing air and water barriers (AWB) with cladding attachments are limited, and installation practices are not consistent across projects. Each of these penetrations have their own unique attachment method, with varying potential effects on air and water tightness and the building’s overall thermal performance. However, the impact these cladding attachments may have on the effectiveness of the AWB can easily be overlooked.
Every professional builder knows about the damaging effects of unwanted moisture, as well as how challenging it is to control water intrusion in certain climates. However, What is not always understood is the role airflow plays in moisture control and how important air barriers are in managing it.
Hundreds of years ago, buildings were thought of much more simply—as shelter, meant to protect people from the elements. Today, that purpose holds, but the technology, practices, and materials that go into high-performing building enclosures have evolved to do more.
