I live in ohio and it gets very cold and very hot. Example last week we were in the 70's today we have hit a high of 34. I was wondering if anyone had used that Fiber board (like the stuff they use on the outside of new build houses? Comes in a big board). We have a large amount of new build homes and they are always throwing this stuff away and I was considering asking some of the builders if they would give me the scraps. It doesn't ad alot of R-value like for a house but I thought it would at least keep it alot warmer.
