Hi, I've framed a load-bearing wall, and now it's almost time for drywall. However, I thought about replacing the drywall with something approved as a firewall for a future wood stove, and I would like it to be as thin as possible. Anyone have any tips? I've seen a calcium silicate board at 50 mm, but I'm hoping to find something thinner if it exists?

A kitchen layout with light wood flooring, black sink, stovetop, fridge, and a modern fireplace near a glass door leading outside.

Grateful for answers :)
Best regards
 
A couple of thoughts.
Stoves also have lateral measurements to combustible materials.
Seems a bit close to the interior on the drawing.
I solved your problem by recessing the same 50 mm panel into the wall so that it aligned with the plaster, spackled and painted it so it is completely invisible.
Took a photo and documented everything for the inspection by the chimney sweep who thought it was a neat solution.
Was able to move my stove 10 cm backward closer to the wall, making it perfect :)

Not an answer to your question, but have you considered the idea of installing a wood stove in the kitchen instead if you want to burn wood there in the future? They are generally more suitable for installation as well.

Thank you for the reply, nicely done :) In my case, it's difficult to do with studs in front. Can send a picture this afternoon but plasterboard extends 1cm from the stud. So there's still a 4cm difference. I have about 20cm to the base cabinet, so there will also be a fire wall there.

Partner pretty stuck on a stove with a big window. It's open towards the living room so it will be quite okay anyway. Now there's just a bit of a struggle over a few centimeters.

Fiber cement boards are available in 12mm thickness, I believe. Whether it's approved, I'm not sure, but it surely depends on how the wall is constructed as well.

The wall is (from outside to inside) . wood facade, wind protection, mineral wool 120mm, wood stud then single gypsum board.

12mm would be perfect but I'm also unsure if it will be approved. I can use 50mm on the side towards the bench. It's the back where I'd like it to be flush with the gypsum.

I don't know if we mean the same thing.
I cut 4 cm off the studs in the wall and then the board stuck out 13 mm (plasterboard thickness)
which meant that everything became completely level.
If you then reinforce the stud, the studs that you've recessed into, you'll get the same load-bearing capacity.
I think I have a couple of photos in my profile of how I've done it.

Yes, that was a good idea. Leaning towards such a solution if I can just manage to get a good reinforcement. Will check your profile. Thanks 👍

Is it acceptable with such a board and wooden beams?

Then I would definitely choose a wood stove myself. Once you're used to cooking on a wood stove, you don’t want to switch back. But when it’s summer, it gets so unbearably hot inside that you end up using the electric stove. They also come with glass doors if you want to see the fire.

The partner can have a fireplace in the living room, and you get a wood stove in the kitchen. Everyone's happy! It's probably easier to place a fireplace with sufficient distance from flammable materials in the living room.

Should be in the user manual for the stove how it should look behind

If only it were that easy. Here are the living room and kitchen. We had a wood-burning stove before and I can't say I cooked on it particularly often. Now it's been removed, so we just have to accept the situation. It seems the only sure thing is a 50mm board in front of the plaster on the side and behind? The studs can't be routed more than a maximum of a few cm.

I have to settle for a fireplace and sausage skewers. It's about picking your battles.. Now I just want to make it as nice as possible.
