Fireplace Hearth Base

[Robbie010]

Hi all,

I’m looking for some advice regards a fireplace hearth.

I’ve opened up the living room fireplace in preparation for a log burner, the base of the fireplace within the chimney chamber is concrete / mortar, but the floor within the room is suspended floorboards, so I need to install a hearth that will straddle the two materials.

We would like to install a stone tile hearth, so I was thinking that it may be best to first lay down a piece of 18mm plywood, screwed through to the floorboards / joist within the room and sat on some kind of cement / adhesive within the chimney chamber. I will then lay the stone tiles on the plywood using a heat proof afheaive.

Assuming the stone slabs are more than 12mm thick would this be acceptable and within regs??

Thanks.
