Firewall for stove, different types? What can I choose?
Hello. New here on the forum...
Hope I'm posting in the right section...
I'm considering installing a stove (leaning towards wood) in the living room. There's a space in the living room that's quite un-furnishable where the stove would fit nicely. (The pipe also comes up at a convenient spot upstairs)
The problem is that it's quite tight with a (wooden) staircase to the upper floor on one side and a wall to a bathroom with a shower on the other side, and it's somewhat questionable if there will be space for the stove + 20cm on each side (which is a recurring safety measure for stoves).
But the stove can be placed much closer if there's a "non-combustible wall" or "firewall". However, I can't find anywhere what different options there are for a "firewall".
This is where all the questions come in.. :S What can be done to create a firewall? Can you put up a metal sheet? I've seen that it can be placed behind the stove, for example.
Gypsum? Directly on the wall or should there be a gap between? Is single gypsum enough or should there be multiple layers? Thickness of the gypsum?
Building both (or all three?) walls with bricks seems out of the question as it will probably become too thick to fit any reasonable stove.
What about the staircase? Does it need to be fireproofed too? The staircase has a full wall up to the stringer/steps, so to speak, on the intended "stove side," but then above the stringer, it's open except for "wooden slats" with maybe 10-centimeter gaps holding the railing.
Made a quick floor plan sketch to show what I mean...
Grateful for all the help and advice I can get.

The boring standard answer is always to ask your chimney sweep because it is they who must approve the installation.
My stove, Handöl 51, had at least 50 cm on the sides as a margin. I built a wall of steel studs and fiber cement boards. There's a similar board at Bauhaus that can handle the same heat.
My suggestion is to stud, place fiber cement against the wall, stud with steel, and then fiber cement again. Good luck!

Ok. Big thank you for the help.
