Hi, could you tile on top of these panels? I am looking for some boarding to cover a space inside my oak fire surround, behind a free-standing bioethanol stove. There are two oak uprights and a top mantelpiece. The back panel would be inside the fire surround and would cover the hole that is there at present. I would like to tile on top of the back panel to create a design behind the stove. The stove would have a gap between it and the back panel. Not sure what to use for the panel as I would like it to have some fire resistance even though the stove is self-contained.
