Plasterboard cracking at flue exit

Blowheads

Hi,
We installed a new boiler stanley stove last year and have a top exit flue at 45 degrees going into a ss chimney liner. To hide all the pipework we studded the wall and covered with fire resistant platerboard and skim. Now all around the flue is cracking and doesnt look too cool.
I am wondering what, if any, solutions there are to this?
Am tempted to take down the plasterboard and do the wall with natural stone, has any done this? if yes, who/what/how much etc.

Or does anyone have any other ideas?

The wall behind the stove is 11ft long x 8ft 6 hight

Thanks!

is there any insulation (rockwool or similar) between the flue and the plasterboard to buffer the heat?

not directly where the flue meets the plasterboard, but behind that to set the direction or the flexi flue liner.

btw, how would you manage to "hide" the rockwool?

foolishly i though that fireproof plasterboard could handle that

what about a picture or two?

here you can see the 45 degree flue going into the wall and the hot pipe going from the stove

see the cracks and the degrading round the flue

goggle 'ceiling ring for flue'

cheers BrianF, was thinking something along these lines, but had no clue what they were called.

where could I get one of these in Ireland?
based on this i will need t take off the flue and then place this around it

if doing this would I be as well take out the cracked plasterboard and fill in around it with fire cement?

while we are at it, what would you do around the heating pipes?

also do you have any experience with a stone effect behind the stove?

1. sorry no idea - ring a couple of stove installers
2. ye why not
3. you'll probably find some similar proprietary solution for those. was this a new house? did you dry-line the place with plasterboard? i wonder is some of this crack due to the drying-out process
4. 'stone effect' is just that, an 'effect', fake, second rate to the real - IMHO if your going to do it, spend decent money on creating a feature, perhaps a slate wall using a clever pattern, otherwise IMHO the plaster painted finish is the way to go, set off with some other element of colour, perhaps some colourful contemporary framed art..

The Fireproof Plasterboard may only by fire rated meaning it is a gypsum board and should not be exposesd to more that 49degC. Fire rated means it will hold back a fire of an 1 or 2 allowing you a bit more time to leave your house before the fire takes over. I see hardwares mis-selling this type of board in their stove corners all over the country. You need a non gypsum High Temperature Plasterboard.
