Fireplace Surround
1/6/2019 at 10:42:02 AM
I have a new install gas fireplace. Steel framing. The stone I want to use is held on with clips and screws. They recommend 1/2 plywood backing board. The framing has the proper clearance from the vent pipe etc.
Am I fine using plywood backing around the face of the fireplace? Or should I use 1/2 cement board(fire resistant)? Either way it's going to be covered with stone.
Would cement board take the clips screws the same as plywood for strength?

By building code, combustibles (plywood) cannot be less than 6" from sides and 12" from top of fireplace, so using hf inch cement board with clips/screws (as long as they screw into the framing behind) would be fine and using plywood abovr would be ok. When attaching heavier materials ie stone always try to use a long enough screw to go into studs/framing as much as posible

Hi there
You need non-combustible materials around the fireplace.....varies per manufacturer.......sometimes 12"on top and 6"on the sides.......Watch bottom of unit and floor finishes in front of unit......Also check protrusion of mantle forward.
Clips and screws will not hold in cement board, but maybe you can use some PL-premium where needed.
Hope this helps,
