What are the most critical wall details for managing water and air—and where do builders get them wrong? Nick Sabol from Huber’s Product Engineering team joins the crew for a technical deep dive into exterior wall assemblies that actually perform.

Pete, Jake, and Nick focus on two of the most failure-prone areas in construction: bottom-of-wall-to-foundation connections and window rainscreen detailing. The discussion breaks down how to properly manage bulk water, maintain continuous air control, and integrate systems so they work together instead of against each other.

Along the way, they introduce RAINA (Rainscreen Association in North America) and highlight why rainscreen strategies are becoming essential for durability across climates. It’s a detail-heavy episode with practical takeaways for builders, designers, and anyone serious about building enclosures—plus, for better or worse, no Dad joke this time.

How much load can insulation actually carry—and are we over-engineering residential buildings without realizing it?

This episode goes deep into the structural and thermal realities behind common building materials. The crew breaks down compressive loading on rigid insulation, long-term creep behavior, and how these factors influence slab and foundation design. From there, the conversation expands into thermal bridging challenges in wood and concrete assemblies, and how innovative framing systems like EcoSmart and Tolko aim to improve performance.

Along the way, they question a core assumption in residential construction: are we solving problems that don’t actually exist? The discussion highlights where engineering matters—and where it may be overkill.

And in true UnBuild It fashion, Steve closes things out with an unexpected design tangent involving beehives.

Climate drives building performance. In the first episode of a three-part series, Pete, Steve, and Jake explore why climate matters so much in building science.

Steve kicks off the discussion with a simple analogy: Would you pack the same suitcase for Minneapolis in February, Honolulu in March, and New Orleans in July? Of course not. Buildings work the same way. Design decisions about insulation, vapor control, air barriers, and drying potential all depend on where the building lives.

The conversation walks through how climate zones influence building enclosure strategy and why national research from the Building America program has shaped modern high-performance construction. And of course, no climate discussion would be complete without Joe Lstiburek’s “Perfect Wall,” one of the most influential concepts in applied building science.

This is the first of three episodes exploring how location shapes building design. Next up: Site and Extreme Events.
