There are a 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).

Unbuild It | Episode 156: Building Standards for Building Professionals?

Episode 156    

In this episode, we dive into the construction industry’s obsession with standards, certifications, and “best practices” — and question whether they actually lead to better buildings. Through a lively discussion on education, building science, and the need to “chase friction,” we explore what it really takes to improve the way we design and build. Featuring insights, debate, and practical resources for building professionals and clients alike.

Unbuild It | Episode 155: ZIP-R on the roof?

Episode 155    

Plenty of folks in our industry have been talking about using Huber's ZIP-R panels on roofs, and certainly, Huber has been working on this as well. But Steve, Jake, and Nick Sabol (lead on Huber's Technical Team) take a deep dive into all the considerations: structural, hygrothermal, and long-term durability. And Pete's leading resource on this topic? Call Steve
