A deep dive into cathedral roof design and insulation strategy. The team compares solid-sawn rafters vs. scissor trusses, smart vapor retarders vs. poly, and discusses optimal roof pitches. You’ll learn when to vent from the topside, from below, or go unvented entirely—and why those choices matter. In the last 10 minutes, the crew unpacks one of building science’s trickiest topics: 6-sided containment of air-permeable insulation—and how it impacts attic R-values and energy performance. ...

134 - Another Double Feature - SIPs vs Stick-Frame & Thermal Degradation of Rigid Insulation
Whole bunch of reasons to consider SIP building systems BUT switching from stick-framing is not a walk in the park. But UnBuild It has a ton of experience with SIPs. Next up: Just how stable are the R-values of rigid insulations (the plastic ones with blowing agents) over time? The boys spend just the right amount of time on this on...(just could not resist that).
