I just had a 24x40 polebarn put up. I would like to hear some suggestions on finishing the inside. I live in upstate ny. I'm planning on heating it with a wood stove, also it will have electric in it. My thought was to run 2x4's horizontality on the outside of my poles in line with the purlins. As far as insulation I would love to have foam blown in but the price for that is crazy. Any one ever heard of or used a product called prodex. I'm thinking on using that. Any suggestions would really be appreciated. THANKS.
