Hi, don’t know if anyone can help me unpick this. We pulled out the gas fireplace that was previously installed and removed everything back to the original chimney breast brickwork. As we did that it became apparent that the person who installed it hacked the right angles off the fireplace brickwork. We are planning on lining the recess with Hardie board, but I am worried that where the board meets at a right angle the void behind it will render the board unstable or prone to break. I think the best option is to pack it out, but I have no idea what to pack it put with… (apart from mortar but I am concerned it won’t key in enough and wouldn’t know the correct mix for what I want, and would I have to shutter it etc…) Any help or suggestions would be great. Lots of pictures attached. The Ply is just for demo purposes

I'll shortly be buying some cement board to use in place of plasterboard behind the woodburner, but it's got me thinking, what's the consensus on using this stuff for its intended purpose? In every house I've lived in tiling has always been done directly onto normal PB, even around baths etc. Not great when the time came to change the tiles, but other than that no problems at all. But I guess the stuff exists for a reason...?

After some online research I've decided to use a cement based backer board instead of plasterboard for the wall behind my woodburner, for increased fire protection. I had assumed that hardiebacker was the only game in town but the different BMs I've phoned have offered me 'multi pro' or 'aquapanel' instead. Is there any difference in the fire rating of these boards? And is there any other material that might be better for the job? Thanks
