Exterior foam insulation now in place

We are making a lot of progress on the Sunnyland Sunhouse & I'm so busy with things that I haven't had a chance to post anything for a while. Here are some pictures of where we are right now.
The exterior is wrapped in 1 inch of polystyrene foam with an R-5 value.

The roof is on and windows are in. Doesn't look too pretty yet but it looks a lot more like a house!

Here is a detail that shows a lot; Studs at 24"oc with the window sized to fit between so that minimal lumber is used. Metal hangers replace cripple studs.

Foam spray in joist bays above seal the space from air leaks. Exterior 1" foam has replaced OSB sheathing where it is not needed for structural reasons. The window header uses 2x material with polystyrene sandwiched between for more insulation value.

At right are some of the decorative knee braces
that will be used on the house. They are built of scrap and recycled lumber. The red-toned pieces are made from fence posts found on the site. They are excellent quality cedar.
