Innovative integrated weather barrier systems that combine structural oriented strand board (OSB) sheathing with an air- and water-resistive barrier not only result in a high-performance building envelope, but they also allow project teams to find efficiencies in design and construction. This course will discuss the components of integrated weather-resistive barrier (WRBs) sheathings, important design details you must be aware of to meet stringent building codes, and how these products can extend a building’s lifecycle and maximize its energy efficiency. We will also examine a new time and labor study that demonstrates how an integrated air- and water-resistive barrier sheathing system can be installed more efficiently than a typical building wrap over OSB sheathing and how this system results in a more energy-efficient structure.
