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.
Still debating on the best way to put the trusses up and will figure that out soon as I will be ready for them.
