Silver Lining Up the Stairs

With warmer, dryer weather this week, they've been working on finishing up the exterior of the house. Now that the roof is on, they've been putting up the ridge foam insulation (the silver coating) on the bulk of the house. As they finish the foamboard, next come the windows and window trim.

Foam on, windows in
The lifts they use to get up to the top of the walls are pretty cool. There is a 'jack' that connects to the long, vertical beam. To go 'up', a person sits on each jack, and at the same time releases a locking brake and starts cranking a handle; the jacks, with the beams spanning them, as well as the people, start walking up the beams to the new height.

The view from our neighbors backyard at the back 3 levels...
The seams of the foam panels are taped from the outside to provide the 'moisture barrier' for the house. The foam provides an initial an R-5 rating and, most importantly, blocks heat transfer from the wall studs (where there is no insulation) to the outside.

Oddly, they've left the side with the fewest windows to do last.
The big surprise was that insulation and windows is apparently just a 2 person job. The other two were inside building our stairs!

Up the stairwell from the basement. They've roughed in the upper stairs.
