I have found the contributers to this newsgroup to be quite knowledgeable about building construction as well as metalworking. For my new and enlarged workshop I am planning to reside an old timber frame barn. I would like it to look like an old barn from both the inside and the outside. My plan is to nail 1 x 8 rough pine boards to the outside of the beams, then cover these from the outside with 1" XPS (rigid blue foam), wrap with tar paper and cover from the outside with 1 x 8 rough pine. The roof would be similar except the outside layer would be roofing steel.
Does this make sense? I am not looking for great insulation, mostly just wind protection. Does this contravene fire regulations?
Any comments would be appreciated.
