When I got to the property Thursday morning there was a large boom arm at the building site. Why would we need a boom truck to put up walls, you might ask?

Well, our walls are pre-built in a factory. Part of what makes this house so energy efficient is tight seals at all sites where air can infiltrate. In order to have tight seals you need square panels. A jig in a factory allows this to be done economically and efficiently. The walls are like a sandwich. A layer of OSB, a six inch layer of Styrofoam, another layer of OSB and then the two by fours.

The walls are a little heavy but more cumbersome than anything. So the boom truck makes it very easy to get them into place. It took David, his guys and Rob and Jim, from the wall manufacturer, two days to get all the walls in place, with the exception of the angled walls.

Looks like I am going to have to step back in the future to get a picture of the whole house. ;-)
