The 3 Keys for Airtight Buildings

October 8, 2020 @ 1:00 PM - 2:00 PM EDT

Live webinar sponsored by the Air Barrier Association of America


The 3 Keys for Airtight Buildings

Presented by Graham Finch


What does it take to achieve a very tight building enclosure? This webinar will address the stringent targets needed for Passive House or Net Zero projects, and even beyond. Learn about design, material selection, and on-site measures to meet your project’s air barrier performance requirements.

As awareness of the benefits of airtightness has grown, many new air barrier materials and systems have been developed and adapted with varying degrees of measured success. Several air barrier systems are emerging as simple, cost effective, proven approaches, and design and testing continue to drive further improvements. This webinar will provide an overview of successful strategies to design, build, and confirm airtight enclosures through informed detailing, material selection, and field commissioning. We’ll share lessons learned from some of North America’s tightest building enclosures and show that hitting very tight Passive House targets is readily achievable with good design and implementation.


Learning Objectives:

  1. Compare the pros and cons of different air barrier materials and systems for different project goals
  2. List key details and design solutions for achieving higher levels of airtightness
  3. Describe how different field commissioning test methods are used to measure and motivate airtightness performance
  4. Apply lessons learned from successful high-performance projects to accurately assess the feasibility of Passive House and Net Zero airtightness targets


Live webinar airing on October 8, 2020 – 1:00 PM EST
