UnBuild It Podcast

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).PETE'S RESOURCES:- "The Complete Guide to Building With Winter Panels:" - BASC SIP Details (SIPA)-"The BuildingGreen Guide to Thermal Insulation:" - "A Study on Variation of Thermal Characteristics of Insulation Materials for Buildings According to Actual Long-Term Annual Aging Variation:" 

Should exterior above-grade wall sheathing or framing line up flush to the outside face of the foundation? Is sealing the bottom of the above-grade wall and foundation with a sill sealer product like Protecto Wrap Triple Guard a good idea? This sets off Jake, Steve, and Pete on balancing water protection, air sealing, and drying potential at this key transition and challenges for control layer continuity. Finally, Steve gets TMI with his sleeping arrangements with his wife...PETE'S RESOURCES:Protecto Wrap Triple GuardNOTE: It is interesting that in their installation drawing, the framed wall is stepped out to line up the framing with the foundation, but they do not lap the sheathing down over the foundation. Huber ZIP Sheathing bottom-of-above grade-wall Detail(s)NOTE: 4 details with "Scenario 4" being spot on for the UnBuild It guys...Above-Grade Concrete Foundation Waterproofing

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...). Gem here from Steve: "70% of a home's budget is hardwired into the number of square feet."PETE'S RESOURCES: - Build Show Podcast Episode 91 - Pre-construction Service Agreements

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... Oh, and we can endlesslyapologize for Steve's parting "jokes"...PETE'S RESOURCES:- "Calculating minimum thickness of rigid foam sheathing"NOTE: Martin Holladay has more than one seminal GBA blog on the topicof adding continuous exterior rigid insulation to meet code--and evenbetter--for greater energy efficiency and maintained moisturemanagement.- "Avoiding Wet Roofs:"https://www.jlconline.com/how-to/insulation/avoiding-wet-roofs_o &https://www.jlconline.com/how-to/insulation/avoiding-wet-roofs-part-ii_o

What could be more fun than yammering on about scary job site stories and just how confusing a space your garage can be? You listeners ask the damndest questions, so we just keep on cranking... Per usual, Steve closes us out with humor worthy of these two questions...PETE'S RESOURCES:- "Does Safety Affect Productivity in Construction?"- From our buddy, Randy Williams: "Construction Design: Humidity Control in a Garage"

The 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 actually ARE spray-on residential roof systems for decks—who knew?).RESOURCES:- Linex residential protective coating- "The Importance of Cover Boards in Roofing Assemblies:"- BSI-051: "Decks--Roofs You Can Walk On:" - (Somewhat related) BSI-093 "All Decked Out:" 

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!PETE'S RESOURCES:- Eric Aune Mechanical Hub- Water testing- CDC Home Water Treatment Systems- USGS PFAS in Tap Water

Eric Aune would make the perfect Marvel Superhero Plumber. With tank versus Tankless water heaters, multiple small tanks, and on-demand recirc systems, Eric brings real-world insight to all sorts of plumbing technologies and techniques. And of course, Steve closes the episode with a special look to his future.Pete's Resources:Eric AuneGary Klein - Saving Hot WaterDemand Hot Water Recirculation SystemUS EPA Water Sense

Eric provides Steve and Jake with a plumber's perspective on almost every residential, domestic hot water system available in the US.

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." Jake springs a pair of UnBuild It questions on Christine: how does ZIP-R work in terms of moisture control and the best way to configure a crawlspace. PETE'S RESOURCES- Virginia Tech School of Architecture- Christine Williamson - https://www.christine-williamson.com & https://www.buildingsciencefightclub.com- "14 Things About ZIP-R Sheathing You Need to Know:" - BSC Condition Crawlspace Construction & Conditioned Crawlspace Detail 

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.Pete's Resources:1. Wikipedia: Barndominium (Who knew?)  2. "When a Barndominium Won't Do, Try a Shouse:" 3.

Since the internet makes us all so cozy from LA to Louisiana, it comes as a surprise to even hard-core building pros that many materials and systems simply don't translate from region to region. Local context simply interferes: price, local expertise, local building codes, availability of materials, even just "no one has done it that way here..." BUT, the internet and social media are shaking things up, in some cool but also disruptive ways.Pete's Resource: - "A Study of the Characteristics of Regional Building Construction Process:" - https://www.researchgate.net/publication/372447144_A_Study_of_the_Characteristics_of_Regional_Building_Construction_Process/link/64b77ec4b9ed6874a52d94d6/download- "The Impact of Digital Distribution on Building Materials:" - https://hubspoke.nafcd.org/Full-Article/the-impact-of-digital-distribution-on-building-materials- "Top 10 Online Sources for Building Materials in the US:" - https://constructestimates.com/online-sources-for-building-materials-in-the-us/

When Steve doesn't show up on time for the podcast, Jake and Pete jump all over the idea of roasting him. But the podcast is mainly about why we love working with the "jamoke." It is about a half-hour of stories about the consummate job-site architect, Steve Baczek, the guy we "can't live with; can't live without him."NOTE: Pete incorrectly calls out Steve's height as 6 - 8; he is actually 6 - 6...

Jake and Pete host good friend Matt Risinger (pretty sure he is “part” of the Build Show...). It starts simple with pre-drywall checklists (you know, like blocking for toilet paper holders...). But boy, it quickly blossoms into a wonderful, wandering discussion of everything from sequencing to quality control to a scopes of work program.

Many of us in the building industry turn to Nikki for all questions dehumidification (certainly including this weeks hosts, Jake & Pete). Nikki goes toe to toe with HVAC techs with a degree in communications and that is because she understands that you have to go tech if you are representing technical products such as dehumidifiers. She connects indoor air quality, occupant comfort, and moisture management. Cool discussion of adding the "D" to HVAC: HVACD or HVAC+D. And apologies to all those expecting (forbearing?)

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.

Daniel Glauser is the Executive Project Manager for Risinger Build in Austin, TX. And he really puts his money where his mouth is. This episode focuses on his deep energy retrofit of a 1977 home in Austin, TX, which will be certified per the Phius Core Revive program. And get this: this soup-to-nuts retrofit is being done while he, his wife, 3 kids, 2 dogs, and several cats are living there full-time. This should be a reality TV show, folks. But on the serious side, Daniel shares all kinds of details integrating the original structure, expansion in 3 of 4 directions, continuous control layers, structural integrity, and fully configured and compliant ACCA Manual J/S/D mechanical systems.

This week's podcast is a discussion about slab-less slabs AND some new projects in which Steve & Jake use alternative or innovative foundation materials or systems. The three boys get off on substantial tangents regarding the environmental profile of foundation materials and construction waste management but hold on: there are great resources below for a host of great topics included in this episode.Resources:- The BuildingGreen Guide to Thermal Insulation - https://www.buildinggreen.com/continuing-education/buildinggreen-guide-thermal-insulation- Design for Disassembly - EPA Fact Sheets on Designing for the Disassembly and Deconstruction of Buildings - https://www.epa.gov/smm/fact-sheets-designing-disassembly-and-deconstruction-buildings- Packer 750 low-speed grinder for residential construction waste - https://www.packer2000.com/residential.htm (Some old dear friends of Pete--Cynthia Poselenzny & Ken Patterson) are the folks who developed this machine back in the day when construction waste management was Pete's "day job")- "Stress grading of recycled lumber and timber" (1999 Forest Products Laboratory publication by Robert Falk & David Green) - https://research.fs.usda.gov/treesearch/5725- Build Show "ICF Prepped for Concrete" - https://buildshownetwork.com/contents/ICF-prepped-for-concrete-steve-baczek

Steve and his "jamokes" (Jake & Pete) share moments that changed their careers. Especially interesting is that the term jamoke that Steve uses is most often associated with CarTalk host Ray Magliozzi in this quote: "If my brother and I proved one thing, it's that just about any jamoke can host a radio show."

 Pete, confused? Pete takes the lead on garages and tries hard not to confuse Steve and Jake (not very successfully...). It's all about how garages are "conditioned" (heated, cooled, dehumidified, ventilated, and filtered) and just what uses the garage is designed for in comparison to the expectations homeowners have in terms of their use(s).Pete's Resource(s):- BSC Information Sheet 802: buildingscience.com/sites/default/files/migrate/pdf/BSCInfo_802_Wrong_Unsealed_Cavity_Between_Garage.pdf- GBA Details for a “High-Performance Garage:" greenbuildingadvisor.com/article/details-for-a-high-performance-garageSTAY TUNED on Pete's Resources: Pete promises a brand new resource in one podcast on this topic (a resource he has not written but will!).

Listeners picked up on two places where perhaps Steve and Jake do not agree (can you imagine....?): Face-seal vs. Drained-rough-opening window/door installations and details at sill plates. After considerable "silliness" (that would be Steve's not Pete's pun...), Jake & Steve reconcile these apparent disagreements with lots of UnBuild It love for each other (WHAT???).Pete's Resource(s): - John Straube's drained rough opening sill detail: https://www.researchgate.net/profile/John-Straube/publication/281442777/figure/fig23/AS:487352062746624@1493205194072/6-Drained-air-sealed-and-thermally-continuous-window-installation-for-a-loadbearing.png - Jake BUILD Show flanged window installation: https://www.youtube.com/watch?v=fED4foylHXY- Steve & Matt BUILD Show flangeless window installation: https://www.youtube.com/watch?v=uAnJq3UH0ro&t=701s- Steve BUILD Show mudsill to foundation install - https://www.youtube.com/watch?v=Up5oAh819y0- Steve BUILD Show SIGA Fentrim mudsill install: https://buildshownetwork.com/contents/air_barrier_tape_siga_fentrim

Client involvement is critical in any building project, but this can be a double-edged sword. We need our clients engaged and to manage their expectations, particularly given how much information/stuff is available online. The boys each give their perspective on the importance and the corralling required for client involvement. Pete's Resource(s):- Custom Builder May 2006 - "Guiding Customer Expectations" - https://www.custombuilderonline.com/guiding-customer-expectations

How do you transform below-grade full foundations (also variously called pits, cellars, or basements and historically meant to be or tolerated as damp and cool and dark) into true living-conditioned spaces? We say add four continuous control layers, access to daylight and egress, thermal comfort, and good acoustics—make it a place to thrive as well as live (and even escape).Pete's Resource(s):1.

It's funny that Steve, a very nuts-n-bolts guy, hosts this largely philosophical episode. But all three of us agree:Separate symptoms from causes—It's easy to get distracted or engrossed in symptoms, but the causes lead to solutions.Solutions come much easier if you first identify the problem(s).Step back to move forward. It's always tempting to jump on the "obvious" solution, but it pays to understand completely before offering solutions.This episode's strength is how each of us—architect, builder, building investigator—uses the approach above to improve our jobs.Pete's Resource(s):Building Science Insights: https://buildingscience.com/bsc-document-type/building-science-insightsEnergy Vanguard blog Building Science 101 (but in the context of Zen and the Art of Motorcycle Maintenance) - https://www.energyvanguard.com/blog/building-science-101/Stewart Brand's How Buildings Learn: What Happens After They're Built (Brand is one of a rare few building philosophers...and his book also is expressed in a 6-part video series - https://en.wikipedia.org/wiki/How_Buildings_Learn#Book& https://en.wikipedia.org/wiki/How_Buildings_Learn#TV_series

Who would have thought that our buddy Steve would be more than OK with both off-site building and the homeowner acting as their own General Contractor? But combining Superior Walls for the foundation with Harvest Homes for all of the framing means the GC homeowner is dealing with far fewer trade contractors.

Tim details his company's approach to architects, customers, and trades, including featuring building science in ALL aspects of their building company.

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.

You know the boys get weepy over water pretty easily, but Steve's focus on starting with the site drives this podcast.

We have a big announcement this week as we return to our first time having Matt Risinger on the podcast.

Jake and his builder team--Luke Mann, (Rangeline Homes), Shane Durkin (Patriot High Performance Homes), and Jackson Andrews (Jackson Andrews Building + Design)--work through all sorts of cool, key approaches to consider with your trades:·      Paying subs in 21 days·      Scheduling a site visit for a new potential sub·      Pulling subs into the bidding process ·      Using suppliers to evaluate potential new subs ·      Trade team kickoff meeting to get everyone on the same page/schedule ·      Setting up debriefs to keep things going well ·      Reducing risk with a stronger trade team

Jake takes his builder team--Luke Man, (Rangeline Homes), Shane Durkin (Patriot High-Performance Homes), and Jackson Andrews (Jackson Andrews Building + Design)--through this final topic with questions like:- Do you want your company to grow? (These guys vary in size from 2 to 16...)- How do you decide when to hire and who to hire? - Are you working in the business or on the business?- Do you have a company culture that suits your team and clients?- How do you delegate/empower/"let go" as your company changes or grows?

Luke Mann (Rangeline Homes), Shane Durkin (Patriot High-Performance Homes), and Jackson Andrews (Jackson Andrews Building + Design) work through this topic with host Jake Bruton. Key concepts include carefully distinguishing punch list vs. additional scope of work; covering closeout in project-starting customer expectations document; an extended comparison of builder closeout process to a new car purchase; dealing with "closeout-creep."

This is Q&A with Adult Supervision: Kohta Ueno. Kohta is so efficient we nailed SIX building enclosure questions: Listener Gagan - reconfiguring existing walls with new control layers; Listener Bill: the need for dedicated vent space with vertical metal siding on ICF walls; Listener Michael - rainscreens for roofs instead of walls; Listener Sean - best detail for using mineral wool (exterior continuous rigid insulation) on a roof; Listener Miles - hip roof in Arkansas best practice: vented roof, vented attic, what type of insulation; Pete asks Kohta's cut on ORNL's new BuildingScienceAdvisor.Pete's Resource(s):1.

Jake hooks up with the same custom builder team Luke Mann - Rangeline Homes https://www.rangelinehomes.comJackson Andrews - Building & Design https://jacksonandrewsbuilding.comShane Durkin, Patriot High-Performance Homes https://www.buildpatriot.comFor a roundtable discussion on the ideal client. Key topics include vetting clients by matching company strengths to client expectations and budget; the two-way street of trust and respect; the importance of references or background checks (they go both ways);  pre-construction services to move the project forward; and finally, red flags...as both warnings AND opportunities.

Guest Reuben Rudisill is Huber's Research, Development, & Innovation engineer, joining Jake & Pete from the Building Science Corporation Summer Symposium in Westford, MA. Jake & Pete know just enough to get in trouble when it comes to structural details of ZIP, ZIP-R, and Advantech Huber OSB panels, so Reuben quite gently sets these guys straight on how high-performance OSB is manufactured and tested, how fasteners are as important as the panels, and what you can and cannot do with each of Huber's panels. The podcast does close out nicely with how important friendships are in the building business world (we could get this "touchy-and-feely" because Steve was "missing" for this podcast...).Pete's Resource(s):1.

Steve calls SketchUp his electronic clay model which he can use with his builder, his enclosure consultant, and his clients. Pete gives up the dirt on WebSoilSurvey, the 1st tool he uses on every project design/spec review. Jake heads home for his favorite tool - his new Aarow Building office. Last but not least: Steve returns with his 2nd favorite tool--the field. Getting out to job sites and seeing his design work play out as a process--no substitute and this tool is key to Pete and Jake as well.NOTE: You have to listen to the entire podcast to understand the Good Fellows reference...but it is worth the wait.

The top leading edge of a PSA tape running horizontally is not weather-lapped or mechanically attached, depending solely on the adhesion of that top edge to the substrate to keep water out of the WRB/PSA tape system. Are ALL PSA tapes in WRB systems self-terminating? Is there a way to quantify the top-edge adhesion that makes the tape self-terminating? The boys go at it over this one!Pete's Resource(s):1.

Despite how consistently and relentlessly the boys have dissed ICFs, this episode takes ICFs seriously and fairly (or as best as Jake, Steve, and Pete are capable of...).Pete's Resource(s)1. "Costs & Benefits of Insulating Concrete Forms for Residential Construction" (https://www.huduser.gov/publications/pdf/icfbenefit.pdf): A bit dated but still useful given that the PATH program (Partnership for Advancing Technology in Housing) is a decent backdrop for a fair analysis of this building technology.2. "Air Leakage of Insulated Concrete Form Houses" (https://dspace.mit.edu/handle/1721.1/72627): Interesting that this energy modeling research reports less than significant air leakage advantage of ICFs compared to wood frame single-family houses.

This week the UBIP takes on the topic of control. Jake tries to convince Peter and Steve that the hierarchy we address the four control layers is wrong. Can Jake turn Peter or Steve to his dark side of ideas? Probably not, but the conversation is still valid. Where do you land?

Lots to consider from frame to finish in terms of materials and connection to main structure. The boys agreed that--for bulk water management--attaching the deck ledger to the main structure should be done either for lateral stability only or with the ledger spaced out from the main structure.Pete's Resource(s):1.
