What kind of walls are those?!?

It is amazing how fast the walls went up over the last ten days.  Our thanks again to the guys doing such a great job!

Let me invite you to take a closer look inside.  
I must admit, I am quite excited to have an "inside" to invite you into!

To the right is a good example of the exterior walls.  
No, that isn't double vision, there really is a gap between two walls.
We have a 4 inch wall, with about a 3 and a half inch gap, and then another 4 inch wall.

This allows us about 11 inches of insulation.  The majority of which will be recycled cellulose insulation.

Heat can also be transferred through the wood in the wall itself.  While wood is not a very good conductor of heat, it does conduct some heat.  As such, the more wood in your wall, that crosses from the inside edge of the wall to the outside edge of the wall, the more heat is lost.

This is the reason for the gap, without as many areas with a complete span of wood from inside edge to outside edge, the less heat, and therefore energy, loss.

Next up, the roof rafters!
