We’re excited to share progress from our project near Bloomington, IN: we count ourselves fortunate to work with inspired owners and excellent builders. Loren Wood Builders is doing a great job on this—not only did they go get Passive House Builders Training, they are being so diligent thinking ahead about components, assemblies, and the integrity of the air barrier. Plus—they have a drone! Here are some photos of the work in progress—you can see we’re using Zip-R (2.5” insulated sheathing) as our air barrier and continuous insulation, over 2X6 studs with cellulose. The slab and foundation are insulated with EPS, and the roof will be insulated with cellulose over the Rothoblass membrane air barrier. Windows are Alpen Tyrol tilt/turn, great performance (triple-glazed) and value. There’s also a shot of the big cistern going in, which is for rainwater collection for domestic use and irrigation.
More coming soon, as the Thermory (wood) and metal siding and roofing go on!
On a perfect late summer day we invited a bunch of friends to watch our first modular prefab house being set.
First off, some terminology: prefab is anything factory-built, so it could be trusses, walls, floors; but modular is when “chunks” of the building (or the whole thing if a tiny house) are built in the factory. We were interested in the efficiency and quality control of prefab, and with modular, we could get windows installed, rough electrical wiring, rough plumbing, air sealing (by using the Zip System for sheathing), cavity insulation, and drywall all done in the factory. In our case, we worked with Hi-Tech Housing of Bristol, IN since they are specifically a custom modular manufacturer, No stock plans here–you just take them whatever you’re interested in building, and they help figure out how to break it into chunks that can be transported on trucks. Once the modules are ready, a “set crew” and crane operator are hired to put it together in the field. (more…)
