R-value is only part of the story. In the final episode of the Back to Basics series, Steve, Jake, and Pete tackle the thermal control layer—and why good insulation means very little if the rest of the building enclosure isn't working with it. The boys break down heat flow, insulation, thermal bridging, and the importance of maintaining a continuous thermal control layer throughout the building. As with water, air, and vapor, continuity matters: transitions, penetrations, framing, windows, do...

Vapor is one of the most misunderstood parts of building science—and in many assemblies, it helps buildings dry rather than making them wet. In Part 3 of the Back to Basics series, Steve, Jake, and Pete break down vapor control, vapor permeability, drying potential, and why decades of confusing code language created so much fear around vapor. As Steve puts it, “Vapor is not a liability, it is an asset.” Buildings get wet. In most climates and assemblies, the ability to dry through vapor diffu...

Airtightness is one of the most important—and most measurable—parts of building performance. In Part 2 of the Back to Basics series, Steve, Jake, and Pete break down how air control layers work, why continuity matters, and how blower door testing exposes the difference between theory and reality. The crew starts with several principles that apply across multiple control layers: staying in one plane makes continuity easier, simpler details are more likely to succeed, and combining control func...

Water is the number one enemy of building durability—and the first control layer every builder, architect, and designer needs to understand. In Part 1 of a four-part Back to Basics series, Steve, Jake, and Pete break down the principles of water management that every high-performance building depends on. The conversation starts where most rain begins: the roof. From roof design and drainage to flashing strategies and capillary action, the crew explores how liquid water moves through buildings...

How do you design a home for floods, wildfires, earthquakes, hurricanes, tornadoes, or ice storms? In this episode, Steve, Jake, and Pete explore what it really means to build for extreme events—and why there’s no one-size-fits-all solution. Drawing from real-world experience, Steve and Jake discuss how high-performance homes can be adapted to withstand the specific hazards of a site’s climate and geography. From flood-resistant foundations and safe rooms to wildfire resilience and high-wind ...

Three listener questions lead to three very different building science discussions—from cold-climate roof assemblies to aging-in-place design and innovative foundation systems. The episode begins with a Climate Zone 7 tongue-and-groove ceiling question, comparing ZIP sheathing and smart vapor retarders for airtightness and moisture control beneath a vented attic. From there, a question about zero-threshold exterior doors expands into a broader conversation about Universal Design and designing...

How much can a building affect human health—and what happens when occupants become highly sensitive to their environment? In this episode, Steve and Pete are joined by retired building scientist and pulmonary physician Nathan Yost for a thoughtful discussion on Multiple Chemical Sensitivity (MCS) and its relationship to building performance. Nathan shares insights from decades of experience working with clients dealing with chemical sensitivities, along with more recent medical understanding ...

Four listener questions. Four very different building science challenges. One highly technical episode. Steve, Jake, and Pete tackle a collection of building puzzles that span foundations, roofs, wall assemblies, and moisture management. The discussion starts with expansive soils and why successful construction often depends on engineered foundation systems designed to accommodate soil movement. From there, the crew examines attic radiant barriers, where they work best, and why climate matter...

Do certifications, standards, and professional credentials actually lead to better buildings—or just more paperwork? Steve, Jake, and Pete tackle one of the more uncomfortable questions in the building industry: why so many standards fail to consistently produce better outcomes in the real world. The conversation ranges from ASTM standards and manufacturer testing to architectural credentials and industry certifications, questioning where standards genuinely help—and where culture, habits, an...

Can ZIP-R panels work on a roof—and should they? Steve, Jake, and Nick Sabol from Huber’s Technical team dig into a topic that’s getting a lot of attention in the field. This episode breaks down the full set of considerations behind putting insulated sheathing on the roof deck: structural loading, fastening and shear, hygrothermal behavior, condensation risk, and long-term durability. The crew looks at where the idea makes sense, where it doesn’t, and what you need to understand before trying...
