High Performance Exterior Air Barrier Details for the Pacific Northwest

Builders across the NW continue to improve the air tightness of their homes, with many getting down to below 3 ACH50 with traditional caulk/foam/drywall approaches. At the same time, the energy code and third-party standards for air leakage rates getting more rigorous across the NW, leaving many wondering how they can make the jump to well below 2 ACH50.

Even when done well, these traditional approaches often still result in significant air leakage at the top and bottom plates, and moving to a continuous air barrier at the exterior sheathing plane can provide a highly effective solution.

Join Earth Advantage for this session with Josh Salinger of Birdsmouth Design-Build where we’ll review tried-and-true construction details and architectural drawings for integrating an exterior air barrier (sheet goods/tapes, membranes, stem walls and top/bottom plate connections, etc). Ample time will be provided for audience Q&A, so come prepared to share your questions and experiences.
