Will attaching 1" rigid foam to the inside of a stud wall create an effective thermal break?
I am getting ready to complete a timber frame project in Northern Minnesota that I started several years back. I left it with 3.5"stud wall envelope sheathed in OSB thinking that I would insulate with spray foam. Since then, I've read about thermal bridging and have come up with a wall system that I believe will address that issue, give me an acceptable R factor and not create a second condensation surface. That is: board & batten siding (locally milled tamarack), OSB, R-15 fiberglass, 1" rigid foam, 1/2" sheetrock. I would appreciate comments.
