Drywall or OSB for shop walls????
I've been a busy little bee in my new (3x larger) shop to be. I've pulled all the old drywall down (1/2") so that I can rewire for my needs and insulate the heck out of it. Once I get that done, I have a decision to make ... what should I cover my walls with? The two competing materials at this point are OSB and Drywall. The biggest reason is cost - 1/2" drywall sheets are about the same price as 7/16 OSB (with 15/32" OSB not far either). Now for some reason, I got it in my head that a garage is required to use 5/8" drywall, but after pulling off all that 1/2" stuff, I'm not so sure anymore.
SO ... it comes down to this ... Drywall or OSB???
Better screw/nail holding capability than drywall.
A little trickier to cut for outlets, but nothing major.
A bit more flamable, which is my worst issue with it.
Will paint well enough for my needs.
Crappy at holding screws, must find studs.
Easy to cut out around outlets and such.
A little nicer finish when painted, but i'm not too picky.
Better fire resistence than OSB.
Right now, I'm kinda leaning toward drywall because of the fire resistence. But that's really the only factor that pulls me toward it. Is my impression of OSB's screw/nail holding ability overrated? I've got lots of studs in this shop, they're actually spaced uniformly (as opposed to the last shop which was wherever the framer set down the 2x4).
Is there an insulation benefit to either that I should also consider?
Anybody done OSB and wished they'd just stuck with drywall?
Really, the cost is about the same (and I really like that), and I'm hard pressed to increase the budget on something else unless there is a significant benefit I'm missing.
So, what say ye?
EDIT: I should add, that my shop is a 24x21 detatched 2-car garage on a slab. The more I read it seems that the code requirements tend to be more on attached structures. I'll ping my local authorities to be sure, though.
