Achieving high-performance wall assemblies requires an understanding of how control layers interact and how construction sequencing impacts enclosure integrity. In this live broadcast session from his mock-up studio, RDH building science specialist James Bourget will deconstruct an exterior-insulated wall mock-up and showcase the use of insulation starters, membrane and cross-cavity flashing sequencing, and strategies for maintaining the exterior air barrier. The session is designed to foster builder engagement through real-time demonstration of the deconstruction process, allowing participants to see firsthand how each detail contributes to airtightness, moisture management, and overall thermal performance.
The broadcast will highlight common challenges and solutions encountered in the field, drawing on RDH’s experience with diverse building types and project limitations. Participants will gain insight into flexible installation approaches, learn how to adapt sequencing for different site conditions, and understand the impact of material choices on enclosure durability. The session emphasizes the value of visual aids and hands-on learning, reflecting feedback from previous training events that practical demonstration and clear visuals significantly enhance understanding and retention.
By the end of this course, trainees will be able to:
This session is ideal for builders, architects, and trades seeking practical, actionable guidance for cross cavity wall assemblies.
