Plywood on walls?
In my basement I have rough-framed a 16' wide u-shaped bar. My plan is to finish the walls and ceiling with all wood wainscote and panels. Not the 70's type paneling, but real stained oak panels. My question is, can I first cover the studs with 1/2 inch plywood before putting up the panels? This would make things a lot easier during the finishing. Or, do I need to hang drywall for code and fire reasons? It will be inspected and I don't want any surprises! Thanks for your input.
