What is a key advantage of continuous air barrier design?

A key advantage of continuous air barrier design is that it minimizes potential areas for air infiltration. This design approach creates a seamless barrier that effectively stops unintentional air movement through the building envelope. By continuously sealing the building's exterior, potential leaks and drafts are reduced, leading to improved energy efficiency and comfort within the space. A continuous air barrier ensures that there are no unsealed gaps or joints where air could escape or enter, which is crucial for maintaining indoor air quality and reducing heating and cooling costs.

While other aspects of design, material costs, and aesthetics may offer benefits, they do not directly address the primary function of an air barrier, which is to control air movement effectively.
