Foam Board Insulation for Side Walls
For those of you that used foam board insulation in your side walls, did you use 1.5 inch? If so, where in the world did you find it. No one carries that size anymore and I really don't want to have to double up because it's already gonna be pricey. Any tips help. I keep going back and forth on what to do and whats the safest to do for insulation and then I can't find the one I decide on lol.
