Does current residential code require drywall on ceilings in single family home without garage?
Remodeling 100 year old Victorian house. We pulled down all the moldy plaster and lathe ceilings, exposing strong joists in good but pretty warped condition. The floor assembly is 2×8 oak joists with perpendicular hardwood flooring planks (1″ thick – no subflooring). The house is modified balloon frame, so we’ll be doing a lot of fireblocking along the walls.
I would really prefer to put up a decorative suspended ceilings (ie, fancy tiles that look like tin or wood) rather than dealing with trying to put up drywall on curved joists. Is that allowed? Or is drywall absolutely required for fire protection between floors?
Thanks in advance for any information.
