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!
