Has anyone ever upgraded or simply replaced your safe interior door fire resistant board. I have one that was stepped on while door was off and is put a pretty good crease in it. Its only 1/2 inch thick material and I'm thinking maybe some stuff at Lowes or Home Depot may be all I need. Durock Cement Board from Home Depot. Thoughts on this would be appreciated. https://www.homedepot.com/p/DUROCK-N...2965/202263276
