30 weight tar paper, 4" beaded styrofoam 4x8 panels, 4 quarter(1 1/8")x6 or better sawmill purlins, then tin. That should give me about a R-12ish which for Tennessee should be fine.
I can say this much for certain. Mice LOVE the blue foam panels.They will chew it to bits.
Have you put any thought on how to keep critters out of the styrofoam panels? I have read that can be a problem in some areas.
I have been enjoying watching your build.
