Built to Last: Strategies for Long-Term Air Barrier Performance

Overview

Length: 1 Hour + 30 Mins of Optional Q&A

Air barriers are critical for residential energy performance—but how well do they hold up as homes age? This webinar presents findings from a recent study that revisited 30 homes, 2 to 15 years after construction, to evaluate the mid-term durability of interior and exterior air barriers, with and without aerosolized sealant (such as AeroBarrier).

Participants will see how diagnostic tools—including blower door testing and infrared thermography—were used to measure building enclosure integrity over time. The session will share observed patterns across strategies, examples of leakage sites, and key considerations for builders, designers, and energy professionals seeking to deliver homes that remain tight and efficient for years after construction.
