I spoke today to the spray foam guy: going to shoot for end of March to do the underside of the ceiling.

However, yesterday, I was speaking to the awesome contractor guy who did my driveway/pad. Here's what my plan was for the exterior of my cabin shell:

Board and batten shell, with boards, not with T-111 siding. I was going to go with foam board in between the batten strips. Then housewrap (or rainscreen????) over that. Then LP Smartside over that.

My guy said no, housewrap then insulation over that, then whatever siding.

Obviously it will still settle and dry some more, and we have been bombed with snow down there like everyone else. No construction is taking place yet...but I'm close! Considering getting some stuff done in a couple weeks when I have time off from work.

Thank you in advance as always!
