THE GOOD news: our homebuilding industry is jam-packed with new materials, new techniques, new systems, and it’s so easy to get information online, in an instant. THE BAD news: How do we know what we can trust; what will work and under what conditions? Where do we turn to separate out the spin-and-hype from the true-and-square? We’ve got you covered! The UnBuild It Podcast is an industry leading opportunity to get good information. UnBuild It podcast is a three member team – Peter Yost; Building Scientist, Jake Bruton; Builder and Remodeler, and Steven Baczek; Architect. We are nationally recognized industry leaders: Jake as a homebuilder; Steve as an architect, and Peter as a building scientist. You can find us at leading homebuilding industry events, in top-notch publications, and online media outlets.We believe that solid industry-related information has four key ingredients;RELEVANCE: You need insight on your job site. Jake, Steve, and Peter are in the field on a regular basis doing what we all strive to do. We walk thewalk – then talk about the walk. The three of us have been working togetherlong enough to build on each other’s expertise, but also not take ourselvestoo seriously. We are among the best at taking what may seem like complicated concepts, breaking them down, and turning them into job site ready breakthroughs.ACCURACY: Jake is often quoted as saying “Trust but Validate.” We don’t ask you to be the bleeding, leading edge; we develop trusted solutions based on our own work in the field, pushing each other to practice what we preach. Our accuracy comes out of triangulation: building, design, performance.UTILITY: We guarantee that each podcast episode will have you moving from all ears to all action. Our information is born from our own work. We pride ourselves on delivering information you can use the same day you make it through an episode. CAMARADERIE: We work together because we love homebuilding, hitting the airwaves, and humor. If you are not having fun learning with us during eachepisode, we are not doing our job.

    Two great questions on which the boys pontificate in fineform. Yes, ZIP-R is "backwards" (rigid insulation interior tostructural sheathing) but that does not mean that it doesn't work; itdoes, just differently. So why don't we typically rain screen roofcladdings? The short answer is it always costs more, regardless of thetype of roof cladding. But you know the saying: vent until youcan't...NOTE: - An Apology: Pete keeps saying "vinyl siding" when he means"vinyl wallpaper" in terms of what many older homes see as newly addedcovering over failed/failing plaster...

    After the boys were done taking jabs at each other, they each take this question and apply it to their fields: building (Jake), designing (Steve), and enclosure review (Pete). Much of the discussion centers on the cost and expectations that both building professionals and clients have or should set with each other. Another central theme is that pulling in expertise early in the design process may seem as though it is more costly. Still, in the long run, it is better to spend a bit upfront and get key input during design rather than costly changes deeper into the build process. Interestingly, the conversation went from cost to trust as a key element of Pre-Construction.Pete's Resources:1. Building-Wright Design-Spec Review (attached - to post on UBIP website)2.

And do ERVs/HRVs accommodate pressure imbalances created by things like exhaust fans, stack effect, etc.?2. Per Steve: to butyl or not to butyl...For areas such as door sills, use butyl sealant or maybe acoustical sealant?

    One of the most interesting ways to accomplish a high-performance below-grade wall is with Precast Concrete panels. Both Steve and Pete have worked on projects using Superior Walls, the leading US manufacturer of these panels. Certainly, it is not the least expensive way to do a foundation, but this system has a ton of advantages: it is completely engineered by the manufacturer, no cast footing is needed, and it can be completed in a day (REGARDLESS of the weather…).Pete's Resource(s):1.
