insulation and osb

Can I put insulation behind osb and install beadboards on top of osb

Why not just use drywall? I assume this is related to your earlier question? Craft paper faced insulation should be covered with a fire rated covering like drywall. I'm not sure about OSB as a wall covering. Bare fiberglass is fire resistant/proof. The craft paper is flammable.
