Glad to see the straw panels are back, I thought they kicked the bucket. The only place I had seen them used was over at Fox Maple. Steve had the ones with drywall as the skin on both sides, Which is what I would like to see. I didn't see them on that link, just OSB. R-25 for the 8" panel, I bet it is heavy.

Some great comments and perspectives. Yes, we need to leave room for the SIPS.
