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...).

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. Has Pete seen it yet? He is still not sure...

What should we monitor, and what do we do about elevated levels of indoor pollutants? Air temperature, relative humidity, parts per million CO2, PM 2.5

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!

Our homes use way more water than you think they need to. The boys dive deep into water efficiency and performance, from toilets to showerheads to hot water recirc systems.

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.

Four Cool Questions: 

1 - Airtight Drywall Approach from Aussie Sean; 

2 - Continuous Insulation (moving from below-grade to above-grade walls) from UBIP buddy Ian;

3 - Frost Protected Shallow Foundations (anonymous) ; 

4 - Roof penetrations from Jake's IG buddy Jeff

NOTE/CORRECTION: Pete got one of his units of measure wrong when stating the standard for an airtight building material. He stated "per meter.." (linear) when the correct metric is "per meter SQUARED..." (area) (See https://www.wrmeadows.com/air-barriers/technical-bulletin-standards-explained-astm-e-2178-standard-test-method-air-permeance-building-materials/)

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.
