I have a new pole building which I wish to use for my wood shop. It has a sealed slab floor and I plan on framing the inside with 2X6. My question is how best to insulate the walls and roof. I thought I might use a thin coating of spray on foam and fill the rest of the space with fiberglass insulation?? Any help would be appreciated.

Skim-coating with joint compound covers texture, renews old drywall and plaster, and leaves smooth surfaces ready to paint.

What's the location of this place? Might make a difference in someone's answer if they knew the climate.
Welcome to BT.
insulating a pole building
Packwood Washington State. In the foothills where it does get to zero in the winters and 90's in the summers.
jeez
that's almost worse than NW Ohio................
Any warm moist air that gets to metal will condense. So your idea of a flash of foam (if that's compatible with metal siding-I've no idea) then perhaps blown fibreglas or cellulose could be a good idea.
I'll defer to those that know insulation way better than this dumb carpenter.
Look up Mooney Wall in the search box up above-you might be able to adapt your plan using the ideas.
From the standpoint of vapor barriers, et al, this building is not "occupied" (at least not enough to matter much) -- the only major source of moisture inside being the part-time occupant who (presumably) will not be cooking or showering in there. This greatly reduces any potential problems with condensation. (That is, unless you decide you must humidify to keep the wood from cracking.)
