Given that environment you might find metal panels more suitable. They
are getting some sales traction in the box stores, so check prices.

That is what is in my garage with no problems. It is ground gypsum mostly.
I put a coat of primer on it but never put a finish coat. Probably never
will. Oh, I did not tape and mud it either.

Usually not recommended due to temp/humidity swings and the resulting
condensation. Even if it doesn't get wet to the touch, it can still soak
up moisture. Unless your well house/shop has stable humidity, the rock
will be prone to getting funky and soft after a year or three. The
exception would be arid climates, where nothing rots.

Like the other guy said, I'd recommend the stuff that they sell to line
pole barns with, even in preference to OSB, which likes to get fuzzy if
unfinished and damp, and sometimes has outgassing problems. Or even the
plastic-coated OSB they sell to skin cheap sheds with. Gotta look at the
long term, even if you have to put off the work awhile until you can
save up. No point in saving money now, if it costs you time and money to
rip it out and redo it in a few years.

Perhaps, but the climate in the detached garage is the same as my house
except during heating season. YMMV

I was thinking about sheet rock without spackling, I wonder if my
insurance company would let it slide. Since I have fiberglass
insulation which states it must be covered to prevent fire.

That's what sheetrock is for - to suppess fires. As it heats, it release a
BUNCH of water.

That said, what's this business about fiberglass being protected from fire?

Faced, undoubtedly; the facing isn't fire-safe.

I forgot to mention the paper vapor barrier. It must be covered. I'm
just wondering if they care if all the gaps are filled so fire can't
easily get behind the sheetrock.
