You say Post-Frame, I say Pole Barn or Barndominium...Yikes. The boys beat up on this topic when we move utility-grade agricultural weather-sheltering buildings (pole barns) to fully-conditioned homes. Aesthetic questions aside, there is solid building science to consider here. And speaking of building science, how do we insulate and air seal rim joists in a way that keeps them dry and durable? This topic takes us from spray foam and capillary breaks to ZIP-R and six-sided containment of interior air-permeable cavity insulation. Oh my. And once again, Steve manages to make us giggle with his closing wordplay.

Episodes

UnBuild It | Episode 133: Deep Dive on That Pesky Transition: Top-of-Foundation/Bottom-of-Above-Grade Wall

Episode 133    

Flush alignment is recommended for better protection. Sealing with a sill sealer can prevent air leakage and water infiltration. Steve's personal info is unnecessary.

UnBuild It | Episode 132: The Pre-Construction Process?

Episode 132    

Plenty of reasons for the question mark: Pete wondered what this term really meant; Jake points out that for most of his career, he was not involved in this process as a builder; Steve gets pretty heated when this process does not include budget (at least a realistic budget...). Here's a gem from Steve: "70% of a home's budget is hardwired into the number of square feet."

UnBuild It | Episode 131: Two Q's: Isn't ZIP-R backwards? Shouldn't we rainscreen roofs as well as walls?

Episode 131    

Two great questions on which the boys pontificate in fine form. Yes, ZIP-R is "backwards" (rigid insulation interior to structural sheathing), but that does not mean that it doesn't work; it does, just differently. So why don't we typically rain screen roof claddings? The short answer is that it always costs more, regardless of the type of roof cladding. But you know the saying: vent until you can't...

UnBuild It | Episode 130: Qs: Job Site Safety & Garage Moisture Management

Episode 130    

What could be more fun than yammering on about scary job site stories and just how confused a space your garage can be? Your listeners ask the damndest questions, so we just keep on cranking... Per usual, Steve closes us out with humor worthy of these two questions...

UnBuild It | Episode 129: A Crazy Space - Decks Over Garages (or worse) & Living Spaces

Episode 129    

Advice starts with "don't ever do this" and then dives into the details for doing it right: slope, overhangs, pedestal systems, step-down from house to deck, and truck liners...Wait, what? Jake describes a long-past project involving a spray-on truck bed liner protective coating (and there ARE spray-on residential roof systems for decks--who knew).

UnBuild It | Episode 128: Master Plumber Eric Aune Part III: Water Sources & Water Quality

Episode 128    

Different water sources lead to different water quality issues. Eric walks us through: sources of tap water; testing water; appropriate water treatment systems responding to the testing results; and a new water frontier: PFAS in our tap water (Per- and Polyfluoroalkyl substances). Yikes!

UnBuild It | Episode 127: Master Plumber Eric Aune Part II: How NOT to wait for hot water!

Episode 127    

Eric Aune is a plumbing superhero, mastering all types of water heaters and recirc systems. Steve teases a mysterious future. Excelsior!

UnBuild It | Episode 126: All Things Water Heating with Eric Aune

Episode 126    

Eric offers a comprehensive view of various domestic hot water systems in the US, from "cold water sandwiches" to "CO2 refrigerant," making it an engaging discussion for Steve and Jake.

UnBuild It | Episode 125: Christine Williamson: From training building practitioners to teaching the next generation of architects

Episode 125    

Jake spends time at Virginia Tech with Christine Williamson, a leading building professional who integrates building science and architecture. In her first year as an Assistant Professor of Architecture, Christine applies building science to architecture courses such as Environment and Building Systems I and II. In her own words about her new position, Christine says, "Architecture education is, I think, a lot closer to more of a fine art program than maybe a lot of people realize. That is something I would like to change."

UnBuild It | Episode 123: Chelsea Scharbach, AKA Rosy the Riveter!

Episode 123    

From metal worker to Director of Architecture Risinger Build to home remodeler, Chelsea is all about working on buildings. Instead of a working-man's Architect like our buddy Steve, Chelsea is the quintessential working-woman's Architect. And get this: Steve & Chelsea are about to team-up on a Risinger Build project!

UnBuild It | Episode 122: Regionality rules us but so now does the internet & social media...

Episode 122    

The internet & social media are shaking materials and systems up, in some cool but also disruptive ways.

UnBuild It | Episode 121: "It's All About STEVE"

Episode 121    

Steve may be late, but we love working with him. Check out Pete's recommended resources for more of Steve's outstanding work.
