Our neighbors, our heroes
Without you, our neighbors, this would not be the neighborhood we'd want to live in. Thank you!

Tight as ... Tupperware
I've been spending a few days on and off over the last few weeks airsealing around the house: mostly where the concrete meets the mud sill, and where the CEB wall meets the top plate. All you need is a caulk gun, a LOT of caulk (I used a GE product, Silicone I, but any silicone-based caulk will work well), and off you go. Believe it or not, this is one of the most energy efficient things you can do to your house (move over, replacement windows!) - so efficient in fact, that EarthCraft standards mandate airsealing in lots of places. Most of them I've covered now - for the rest of the airsealing (and firestopping), the professionals from Southland Insulators will take over before they apply sprayfoam insulation to our roof, the clerestory window area, and the bandjoist. More on that in a future post.
For now, just a picture of a nice, thick, bead of Silicone caulk between the top of the CEB wall and the top plate. Often under-appreciated, but such an important component of building green.
EIFS, Act 2
Claudia and her EIFS crew wrapped the house in extruded styrofoam today. (Yes, there are different kinds of styrofoam: expanded - the white, bubbles-pressed-together looking kind; and extruded - which is much smoother in texture.) The advantage of extruded styrofoam is that (a) it has a greater R-value (R-5 per inch ... we have three inches, so a total of R-15) and (b) it is a water barrier (by contrast, expanded styrofoam is about as permeable as a sieve).
For now, the house looks like a big freezer box. The next few steps are to sand the styrofoam smooth; embed a nylon mesh in another scratchcoat, and then to apply the final EIFS coat. In a week, weather permitting, we should have the final product.

EIFS and Window Framing Progress
Thanks, Jeff!

Wrong Windows Removed, More Flooding
Puddles, Puddles everywhere
This rain is driving me nuts! Bartley returned on Tuesday with the repaired machine to continue the grading work. The clay dirt was too wet for them to complete the job, so they'll have to come back again after 4-5 days of no rain, which will give the dirt time to dry out. At this rate, I don't think we'll ever have that kind of dry spell!
While doing the grading, the guy from Bartley drove right into the corner of our house, completely destroying three of the extruded foam board panels. Hopefully when the EIFS installers come, they will be able to easily add new foam board there and make it like new. You can see the foam board we cut away in the fourth picture below.
On Thursday, when I was in an important all-day meeting, I received an email from my neighbor to the South stating that our silt fence needed attention. You will see in the final picture where the torrential rain storms that afternoon, following days of steady rain, were just too much for any silt fence to handle. I went that night and put up an extra layer of new silt fencing, hoping that holds in the future. Once the grading is complete, hopefully this won't occur again. If it does, we might be forced to incur even more water mitigation expenses (which we cannot afford) in terms of draintile to prevent water run-off.
Prepping for EIFS Installation
In order to secure the best possible price for the EIFS installation (that's the extruded foam board and synthetic stucco system on the exterior of the house), we agreed to attach the basement extruded foam board to the house using TapCon concrete screws. That saved time for the installers, which saved us money. Andreas did the work, which took a few hours, about 100 TapCon screws with large washers, and five concrete drill bits to pre-drill the screw hole. Doesn't it look great? Now the EIFS installers will be able to nicely match their foam board with ours for a professional installation.

Grading in Progress

Rain, Rain, Go Away
We're receiving quotes for ceiling and wall insulation (the wood-framed clerestory wall, not the Terrabrick wall). Closed cell spray foam is the best choice, but it's the most expensive by far. So we're considering a hybrid which will be a closed cell spray foam application that would be about 2-3" thick and then a zero formaldehyde blown in fiber (it's called the spider system, since a web holds it all in). Combined, we will have an R50 insulation value for the ceiling and R23 for the clerestory walls. That option is several thousand dollars less expensive than 100% closed cell spray foam, which would give us about an R41 insulation value. We're still receiving quotes, so if anyone has a good company that's experienced in spray-foam insulation, please let us know.
Importantly, all of the quotes we received also include a foam sealant or high-grade caulking to seal all penetrations in the thermal envelope. This will be a very tight house!
