Log burner question

So I'm putting in a multi fuel stove. It's in the centre of my gaff so It will be double fronted with glass to living room and dining on the other side. On the internal fire place walls I have boarded them but someone mentioned to me that even with a porcelain tile the heat could remove the paper from the plaster board and it could all fall off. Anyone heard of this before. Firstly I'm not concerned with fire as behind the board on both walls is solid brick. Secondly the fire gives off the majority of its heat through the glass facing each room and not much should come off the side of the fire itself. Do I need to remove the board and cement board or S&C the internals or would I be ok to tile on it directly with vitcas heat proof tile adhesive. It's rated to 1000°. I'm thinking if the heat can get through porcelain tile and that adhesive then it doesn't matter what's behind it. Any ideas

This is the fire I'm looking at having and there will be 6 inch clearance from fire to internal side walls

Personally I'd take the plasterboard off and use cement board, why take any chances when installing something like that?
Six inch clearance at the sides is fine, I've got less than that on one of mine, but don't be fooled into thinking that there won't be a lot of heat coming from the sides, there will.

I had a fire similar to that in @Tinytom ‘s pic..........and when it was stoked up on a cold day the heat from the fire cooked the bressemer beam and it began to smoulder.........all correct distances etc all rules followed, hetas fitter etc.
They get bloody hot!

That is a geocast beam, it’s non combustible

What about a glasroc F multi board , 6mm white faced no need to skim it or use that horrible victus gear
A1 fire rated too

I'm sure that this is what so stove companies are using round our way.
They have to have fire cork at the internal join but with a stop bead placed at the front can hide the board edge and skim front of breast and leave the inside not skimmed tbh it looks neat too when finished, last one I did £25 for 8ft x 4ft sheet though mate

6mm? No way I reckon that will bend
You can bend them if needed mate but they the only board that do tbf, but if dabbed or fixed flat they will stay flat tbh I never knew about them until about three years ago last month I had to rectify a bodged fire job , that is what we used
They do have a heat recommendation limit of 49c though so don’t know how that fairs compared to others , but all jobs were heatas approved
Has to be fire cork though

I mean at 6mm I reckon the heat from a fire would bend them, first one I ever did was with 6mm superlux I dabbed it and got a call within a month to say they had all bowed away from the walls

So I'm putting in a multi fuel stove. It's in the centre of my gaff so It will be double fronted with glass to living room and dining on the other side. On the internal fire place walls I have boarded them but someone mentioned to me that even with a porcelain tile the heat could remove the paper from the plaster board and it could all fall off. Anyone heard of this before. Firstly I'm not concerned with fire as behind the board on both walls is solid brick. Secondly the fire gives off the majority of its heat through the glass facing each room and not much should come off the side of the fire itself. Do I need to remove the board and cement board or S&C the internals or would I be ok to tile on it directly with vitcas heat proof tile adhesive. It's rated to 1000°. I'm thinking if the heat can get through porcelain tile and that adhesive then it doesn't matter what's behind it. Any ideas

Rob this is mine I’ve tiled inside onto board granted they would come of easy ! But who cares they ain’t moving been on at lest 5 years I quite like the cracks and dints around the fire now the amount of timber I’ve loaded the fire over the years it aint no surprise .

Personally in the opening i would go for brick or brick slips on the cheeks up to the register plate then tile the front face either side. 150 mm either side of the stove is not a lot at all. If you are dead set on tiles inside i would be using hardy backers and you need to make sure the tiles have a good solid bed of adhesive cos any voids with air in then will expand and blow the tile when the fire is in use.

Cheers lads. I can put anything on the inside of the fire surround. I was just looking at tiles for ease. On the fronts of the fire I will be putting Venetian plaster on one face and either Venetian or micro cement on the other face. It's interesting bagrat that yours has stayed on. It's quite close from the fire to 're internal wall too

by that do you mean you still tile with a notched trowel or put the adhesive on with a flat trowel to remove any air spaces

i know it is off thread but may be useful. my son in law ran a duct from the flue of their wood burner to heat up another couple of rooms instead of wasting the heat.

The air spaces won’t be a problem mate, I don’t use tile adhesive, I use a heatproof silicone based adhesive called maximum torque, sticks like s**t to a blanket

From the flue? As in products of combustion pumped into another room? lol that’s called suicide or murder depending who’s in the room.

i am not sure it is from the flue, our local plumber has done the same.
