Advice needed on preparation for wood stove installation whilst renovating lounge

[Tirglas_7]

hi

continuing on with my 80's dormer renovation, i'm now on to the lounge.

at this point with a view to installing a stove in the corner, is it worth me using fire resistant plasterboard or similar on the stud wall? i'll be installing rockwool slab insulation between the studs.

all the current floor is coming up and being replaced with osb3 t&g boards, i'll be installing 100mm foil faced pir between the joists (already have a few sheets i need to use), should i avoid using this around the fire area? also should i use any other kind of flooring around the fire area?

Wall will be stripped back/skimmed, sockets relocated and skirting board removed

Not sure whether i'll be going down the full install by a hetas installer, partial install myself if i can find someone happy for me to the donkey work etc or a full diy with BC.

Got to admit, some of the prices i've been quoted are eye-watering for full installs, which is pushing me towards doing it myself. Excellent site for diy info is stovefitterswarehouse.co.uk they design all the flue etc to current regs for you, the site itself is full of information.

many thanks for your time

How far is that wall with the power point from the stove?. You will need to download the installation instructions for the stove you would like to fit which will tell you how far away from combustibles it needs to be and the temperature of the underside of the stove to see what thickness the slab needs to be if on a combustible floor...from memory the slab size should be a minimum of 840 x 840mm. If not already done, download a copy of part "J" of the building regulations which will help

Why not instal the stove at 45degrees in the corner so's it's radiant heat projects into the room

Many thanks for the reply,

I can relocate the socket etc as I'm lifting the floor anyway.

I'd like to get it as close to the corner as poss, if I used fire resistant materials, plasterboard etc, will that allow me to get it closer? Would it be classed as non combustible etc?

Many thanks for the reply,

My drawing isn't great

We like the cylinder type, like you say at 45 degrees. What was putting me off was the stud wall, that's why I hoped we could maybe use the fire resistant pb. if I can get it as close into the corner as poss by using different materials, fire resistant plasterboard or anything similar then I'd like to install it at this point.

Or is it easier to just install normal materials, then install the stove using the relevant non combustible measurements?

 

[lostinthelight]

Any firm of plaster board is regarded as combustable, have a look at Hardie backer or other cement boards

 

[Tirglas_7]

Ah ok, I'll start looking at cement boards then.

Do you know if timber stud covered in the cement board is classed as non combustible?

Thanks again, much appreciated

It has to go on masonry to line it, not on studs

 

[Tirglas_7]

Right OK,

Will just have to spec a fire with with as low as poss non combustible measurements then. Was hoping if I used some fire resistant materials i might of been able to reduce the distance to the walls.

Makes it easier for the rest of the renovation anyway if I'm just installing standard pb etc.

Thanks again for all the info

If you look for a convection rather than radiant stove they generally have a closer to combustible spec
