Is this an ok fireboard for fireplace and then tiling over?

HI.

I was wondering if anyone could help us out. I've attached a picture below to help in my description. (Sorry if I don't use the correct terms)

Image 1: This is what I've built so far. I'm going to use a multi fuel stove and I've already had the flue installed.

Image 2: My plan is to construct with the use of fireboard a panelled area which I've highlighted in red in the image. Once that's installed I'm going to tile over the red area and the hearth, which is coloured dark blue. The only area I'm not going to tile is the 2 horizontal panels, just paint them black with heat proof paint. Using board would give me the flat surface to tile over.

Image 3: That’s all the cuts I'm going to need.

So my question is:

Could I use this fireboard if I'm tiling and painting over it?

It's not getting direct heat and it will have tiles/paint over it.

Could I use these tiles for the red and blue area?

The 2 issues I can think of are. Will they discolour, or will they crack due to the heat?

Thanks for any help.

Was planning on starting this sometime later in the week, so any info will be welcomed.

As this comes up so often, I’ve put together this generic post; read the links but not all may apply to you.

You can DIY a stove install but you need to understand the Building Regs (which changed in October 2010), submit a Building Notice & pay a fee. Your LABC will inspect &, assuming everything is OK, issue a compliance certificate; the BI may want to witness smoke & spillage tests. No compliance certificate may lead to difficulties when you come to sell your property; if cannot produce a compliance certificate in the event of a problem, your insurance company may invalidate your policy & reject any claim.

Lots of archive threads on this, & other things you have to watch out for, here a few links for you to read:

Also get at least 3 quotes from local independent HETAS installers:

You might be pleasantly surprised & you should ask yourself if you really want all the hassle & risk getting it wrong; climbing onto the roof with an 8M stainless steel snake on your back is not for the feint hearted!

Thanks for the links. I've already had the flue, register plate, etc put in by a registered installer and he'll be coming back to fit the stove, once the surround is done.

I was just planning on boarding and tiling the red and blue area in pic 2.

With regard to the Wickes boards; their web site doesn’t give any info regarding spec or manufacturer but most “fire line” boards are made from Gypsum based plasterboard (with additives). These are only intended to provide a one off protection to the limit of their certified fire rating; they are not suitable for continual exposure to temperatures above 49 degrees. The temperature in the fire opening is likely to be well above 100 degrees & any gypsum based board or plaster will fail in a relatively short time.

You need a Silica based boiler backing board; Hotrod recently built a false chimney breast using similar over a steel frame (you cant use timber) & finished it off with Vitcas heat proof plaster so he has good experience. Looking at your sketches I would normally use a 2 coat sand/cement/lime (5/6:1:1render) in the fire opening, second coat weaker than the first. You can tile directly onto that once it has dried out thoroughly (4 weeks). For the tiles, you will need to use a quality trade (not own brand or DIY crap) powder cement adhesive (not tub mix) which will withstand heat of around 150 degrees; I use BAL Rapidset. Most ceramic & porcelain tiles will withstand the heat but you need to be careful with expansion & contraction.

It’s a personal choice thing but I think the bevelled tiles you have chosen will look rather odd in a fire opening & satin black will mark fairly easily; I know this because I’ve got them in my kitchen I would also think they will stain in a fire opening. I nearly always use large format black granite tiles (60 x 30 x 1cm); the one’s I buy are nearly 20 quid each so you don’t want to be making any mistakes cutting those! I lay them with a 1/2mm gap which I silicone rather than grout; grout it will most likely crack & fall out due to continual thermal expansion/contraction.

Make sure your HETAS installer commissions/tests your fire & issues you with a compliance certificate.

Thanks for the help Richard, you've helped clear a few issues up. And regarding the satin tiles, they were someone else's choice who has since been convinced otherwise.

Sorry for bumping up an old question but I returned to the forum and was looking over old posts. Thought I'd post a picture of the final build. Just in case someone searched for a similar problem and it's always good to see the outcome.

Used a promat supalux board, painted black with heat proof paint. Topps tiles mini satin black with white grout. Mendip Churchill 5 multi-fuel stove.

Had it going all winter, no staining on the white grout and great heat off it.

looks spot on

Just looking at your fire-place .Good job really nice. My missus was lookin over my shoulder and said ," That's gorgeous" So there's a complement for you.
