Build Science™ 401 | Episode 8: Common Above-Grade Wall

Episode 8     Share

Build Science™ 401 Episode 8 walks through above-grade wall and floor-to-floor transitions, emphasizing how structural framing, drainage, air, vapor, and thermal layers must remain continuous to create a durable, resilient building envelope. Using a real New England home as a case study, Matt Risinger and Steve Baczek explain why engineered floor systems, rain screens, ZIP System sheathing, and simple, repeatable details reduce risk and improve performance.

Build Science™ 401 Episode 9 uses an early Passive House double-stud wall as a retrospective case study to explain how the four control layers must work together as one integrated system. Matt Risinger and Steve Baczek show how ZIP System sheathing was leveraged to do multiple jobs—water, air, and structure—while redundant sealing, staged insulation, and careful blower-door testing were used to confidently achieve the 0.6 ACH50 requirement.

Build Science™ 401 | Episode: 11 Vented Roof Assembly

Episode 11     Share

Episode 11 of Build Science™ 401 covers an in-depth discussion on system integration in high-performance building envelopes, specifically on how the four control layers integrate into a vented roof assembly. Matt Risinger and Steve Baczek explain how various layers are connected to create continuous air and vapor barriers, while vented roof assemblies and baffles ensure proper airflow and drying potential.

Build Science™ 401 concludes with Episode 12 where Matt Risinger and Steve Baczek review flat roof design, insulation strategies, vapor profiles, and the importance of coordinated detailing between trades to ensure durability and performance. They cover details of a flat roof, including slope, insulation, membrane protection, drip edges, lack of parapets, and roof overhangs, with practical reasoning for each design choice.
