Installing windows is getting more, not less, complicated. Pete lobbies for a different, more durable, and simpler gasket installation of windows. Steve and Jake weigh in with their insights and challenges to what Pete is up to. And a bonus: with Steve and Jake's help, Pete creates a new word: "Poninions" (Pete crashed the words opinions and positions, and his "friends" just could not let it slide).

The boys start with a really cool problem-solving involving a monopoly framing, big overhangs, and thermal bridging. And the follow-up is an excellent question from Western Canada regarding the use of ZIP sheathing with a Class I interior vapor retarder. It's a great discussion involving R-values, air barriers, vapor permeability (including all Classes of vapor retarders), wetting, and drying. Whew! Good thing that Steve had a "great" joke to close this one out...(gag).

If you can't find an experienced high-performance builder, then find a professional builder who is willing to listen and learn! And add in time and money in the budget for that listening and learning. The same can go for your architect. But as Steve says: "SOMEONE has to drive the bus. Put on your big boy pants and move your business to the next level."

All 3 UBIP podcasters are fond of the Superior Wall System, but connecting the extended "foot" of the foundation wall panel to the basement slab is a bit tricky. But not for Steve, but of course. And while sump pumps OUTSIDE are a mystery to Pete, Jake & Steve walk Pete through it. And a bonus: using gravel to spread the structural load and better manage the water load. All that and a "joke" by Steve to-just-die-for...

Once again, we drive wood into the ground, but only in the context of Permanent Wood Foundations. No surprise that this discussion is all about water & drainage. And some episodes ago, the boys each revealed pivotal moments in their careers in the building industry and wrapped up with a request for your pivotal moments. We got one, but what a doozy from our buddy Carl Seville of SK Collaborative. I think we might be done now (at least for a while) with PWF, but come on now: email us your pivotal moment in our industry!

Two great questions about wall assemblies. The boys dig deep, exploring all the variables to consider for both wall assemblies. And no big surprise: Much of the conversation is about how to get these three control layers right (water, air, thermal) and ALSO get the drying potential (vapor) correct.

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).

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 Guard
  • NOTE: 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.

  • NOTE: 4 details with "Scenario 4" being spot on for the UnBuild It guys...

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."

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 it always costs more, regardless of the
type of roof cladding. But you know the saying: vent until you
can't...

NOTE: - An Apology: Pete keeps saying "vinyl siding" when he means
"vinyl wallpaper" in terms of what many older homes see as newly added
covering over failed/failing plaster... Oh, and we can endlessly
apologize 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 topic
of adding continuous exterior rigid insulation to meet code--and even
better--for greater energy efficiency and maintained moisture
management.
