Jordan shares a high-performance wall assembly built into a stunning barn at the Monarch Woods project in Texas. Drawing from Joe Lstiburek’s “Perfect Wall” concept, Jordan breaks down how this single wall meets all five essential functions: structure, water control, air control, vapor control, and thermal performance. With layered detailing—from corrugated metal cladding and Rockwool exterior insulation to carefully installed housewrap and airtight plywood sheathing—this wall performs at passive house levels of air tightness, all while keeping its structure proudly on display.

Jordan also explains the trade-offs behind using steel vs. wood, how site decisions influenced material choice, and why this same system was adapted differently for the main house. Plus, he shares how they used an exterior wall system as an interior partition to isolate a garage from a small apartment—ensuring clean air and zero cross-contamination. Packed with practical insight and design philosophy, this episode is a must-watch for anyone serious about building smarter, tighter, and better.
