A Guide to Exterior Air Barriers and Building Envelope Detailing

This CHBA-CO Industry Education video was created for builders, framers, and trades looking to improve their understanding of building envelope performance and exterior air barrier systems. Learn how to design, install, and detail air, water, and thermal control layers for airtight, durable, and energy-efficient homes that meet or exceed BC Energy Step Code standards.

In this short video, you’ll learn:
• The key control layers of the building enclosure and how they work together
• The five essential requirements of an effective air barrier system
• How to detail windows, doors, and penetrations for airtight, watertight performance
• Installation tips for membranes, tapes, and sealants to ensure continuity
• How to integrate ZIP sheathing, EPDM gaskets, and ICFs into your envelope design
