My 1869 farmhouse is finally completely finished on the inside. I filled the wall cavities with 3” closed cell with 3” rockwool. I sealed everything I possibly could, but there was only so much that could be done given the irregularities of such an old home.

In refinishing the exterior/siding, I’m wondering how I can best assist sealing the envelope. I planned on incorporating some EPS, but not sure about houswrap or any other ideas. Looking for help!
