We are working on a bathroom remodel and will be putting tile on the walls above the tub. For the side walls we plan to use the 1/2" thickness cement boards. The back wall is an exterior wall and we are require to use 5/8" fireproof drywall. My questions is, could we add the 1/4" cement board on top of the 5/8" drywall?

Answer: 
No, 1/4" thick cement board products are not allowed on walls. A fire-rating can still be achieved on the exterior wall using 1/2" PermaBase by adding mineral wool insulation in the cavity. Please call 800-NATIONAL for details regarding the fire-rated assembly.
