134 - Another Double Feature - SIPs vs Stick-Frame & Thermal Degradation of Rigid Insulation

Why is building a high-performance home so frustrating? Steve Baczek has some strong opinions about the challenges facing architects and builders who are trying to deliver better-performing homes—and Jake Bruton is happy to let him vent. From clients who want the best of everything without paying for it to an industry that still struggles to understand what high-performance construction actually means, Steve breaks down the frustrations of designing and building homes that prioritize durabil...

Do high-performance homes have to be expensive? Steve and Jake tackle one of the most persistent misconceptions in building science: that better-performing homes are only practical for wealthy clients with luxury-home budgets. Yes, Steve and Jake work on plenty of high-end custom homes. But the price of those projects shouldn't be confused with the cost of applying good building science. Better water management, airtightness, insulation, durability, comfort, and energy performance aren't inhe...

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...
