New polebarn, I will be putting in insulation in roof and walls for
inside heating for Michigan winters. Surprisingly, the cost is about the
same for either locally. I would prefer OSB on the walls, to make it
easier to build shelves, ect onto. Is this a problem, or is there a
reason to use drywall? Thanks, Earl


Fire resistance and vapor barrier fiberglass requires a fire resistance
covering (drywall) per code and manufacturers instructions.
