Did you insulate under the OSB? If so, that would make for a very nice shop. Insulation, then OSB and then a steel liner on top would be a heck of a combo.
there is 7/16 OSB on the exterior with Tyvec, 6" fiberglass in the walls. a 4 mil vapor barrier and then additional 7/16 OSB. The Steel screwed directly to the OSB. The building is tighter than a Zip Lock bag. I have radiant floor heat that cost less than $100/mo to keep 2000sq at 60deg 24/7. Turning on the lights raised the room temp 3 degs
Again thank you. I am proud of this shed, I designed and built all aspects (except the concrete - I let younger backs do that) from the building lay out, electrical and heating system and the only thing I would change is the concrete contractor... long story - poor workman ship
