Sustainable Village Week 10: electric, exterior foam & and spray foam

Workers began adding exterior foam to the homes, which will all have some version of a REMOTE wall-meaning the majority of insulation goes outside the vapor barrier and sheathing (learn more about the wall system here). Three homes will be insulated with 8 inches of EPS foam board and one will be filled with cellulose, for an R-value of 60 apiece. We also sprayed a foot of polyurethane foam insulation under one of the raised pile foundations, for an R-60 floor.

We trenched the communications lines and electric, and finally turned off the generator! Next up is spray foaming the rim joists, finalizing plumbing and electric, and hanging Sheetrock, which will probably begin later this week.
