I don't blame you one bit. I wanted to, but the wallet dictated otherwise.

Out of curiosity, what were you quoted to have it all foamed?

As to my location, North Central IN. So decently cold winters but not extreme by any measures; was 8 on the drive into work this morning. I know the primary purpose of spray foam (no snarkyness intended). Have it in the house walls, rim board down onto the ICF basement walls, and above the drywall on the second floor to make a complete envelope for the place. It's about as air tight as it can be.

With regards to the barn installation, I foamed the sheets against the purlins as well as against the posts. The seams are also foam sealed/glued. They'll be vapor barrier over the final layer of fiberglass as well as under the ceiling metal/blown in fiberglass to further restrict/block airflow from entering the main portion of the building. While the barn is strictly for storage, I still wanted it well insulated and capable of being 'warm' without having to pump a ton of heat into it. Honestly hoping that once the radiant floor gets the cement heated up that mass keeps it's in the 50s.

The barn builder put up house wrap under the metal as I was originally intending to do spray foam (was under the presumption the price had not more than doubled in the 7 year span from doing my house). This would have resulted in easily being able to replace a panel when I run into it, or the darn hooligan kids of mine do, lol.
