Hey BeezFun, just the roof material and the siding. All steel panels. All framing is wood. I did look into a steel building( framed with steel) but they were quite a bit more money. I don't remember right now how much more but it was significant.
Thanks Gittyup, never heard of this but I will definitely have to look into it. Of corse here in NY, we don't see the sun very often. Getting it to 60 would be perfect.
