Jim,
that's what I was saying with only two braces between each bend at 8' height or more. This would not be sufficient for me. Yet, I see it all the time. So those frames must rely on the SIPs.
That Sips are what they are was clear to me but when pegs_1 brought up the structual and not structual SIP I had to ask.
Thomas,
check out the German Timberframe thread. I explained the wall detail there.
