I have another thread about having my new prebuilt shop being delivered this coming week but I wanted to come here and ask about insulating it. My shop will have 2x4 framing with 3/4" pine siding. My shop area is only going to be about 10x12. I will still need to run electric after it gets here as well. I need to know what is going to be the most economical option. I'm guessing roll insulation. Then that also means that I'll need to then cover the walls with some kind of wall board..... OSB? If I do it this way do I also add a layer of plastic before I put on the wall board to act as a (vapor barrier)?
Does this sound like a plan or am I missing something? I have wondered about foamboard sheets instead of the roll insulation.
