Replace plasterboard walls with chipboard

[SteQve]

Hello!

This summer, I'm going to move an interior wall at home and replace some interior walls from drywall to chipboard. My father built his house (-78) that way, and it's so much more fun to attach something to chipboard than having to use a molly and ruin the wall.

The question we initially wonder about is whether it's okay today to replace drywall with chipboard. Drywall doesn't burn well, but chipboard does better. Are there any regulations that make it impossible to use chipboard as a result?

If you now replace drywall with chipboard, do you dimension it the same way? Single drywall = 12mm chipboard (not MDF because I don’t particularly like those).

Grateful for an answer!

Why not chipboard AND gypsum? That's how we put it everywhere.

 

[SteQve]

hehe, well...spån on the outer side and plasterboard towards the insulation?

not a bad idea, you could perhaps reduce the dimensions of both plasterboard and spån?

 

[Gladh]

hehe, well... chipboard outermost and drywall facing the insulation?

not a bad idea, you might be able to reduce the dimension on both drywall and chipboard?

I would place the chipboard inside before the drywall. So first chipboard and then drywall. This gives a smoother wall to paint and wallpaper on.

Yes, I figured it out. It should also be better from a fire safety perspective. But I currently have single gypsum 12mm... how do I dimension chipboard + gypsum?

 

[Lindgrenski]

We use 10mm spån and 12.5mm gypsum.

if it is a non-load-bearing wall, it works quite well with a 45 mm stud in the middle. 2 pieces of 12mm chipboard on the outside of that and then 2 regular gypsum boards.

 

[SteQve]

No interior walls in the house are load-bearing, so it's very open in that regard...

However, I was thinking of using a 70mm stud. Is that overkill?

 

[ByggaNytt]

No, all my walls are 70mm + OSB/gypsum on each side!

 

[Mats]

Absolutely nothing wrong with 45X70. Just a little more work with the doorframes but it provides a more stable wall.

 

[SteQve]

yes, I was just thinking about that with the door frames. If I now have 12mm gypsum, and switch to 10mm chipboard + 12mm gypsum, how do I make it look nice?

I can indeed change the door frames if it helps. A wall should not be demolished which is why I can't go down to 45mm everywhere. Or rather, the wall where the door is in should not be demolished, but just change the material in it, which is why I can't change the stud thickness.

The alternatives are to do something with the door frames, or alternatively to change them.

You put heel linings, or alternatively rebates, on the frame before nailing the trim.

my father and I discussed a wall where I preferably don't want to have more distance from the ruler than what is today (= 12mm from the drywall).

6mm plywood + 6mm drywall should be a good solution there. It's strong but doesn't extend from the wall more than before. It can't be worse than 12mm drywall which I have today. And it has held up for the house's first 28 years...

Isn't an OSB board behind the drywall preferable to particle board? I have a feeling it's easier to screw in, for example, shelves, paintings, etc., into OSB which isn't as hard as particle board?

Or was I just unlucky with my thinking now...

 

[Plupp 23608]

No, OSB is better than chipboard and plywood is better than OSB. I think that 6+6 is too "flimsy" to be good, and in my opinion, 6 mm gypsum should be avoided at all costs.

Is it just me who thinks there's been a bit of "hysteria" around the idea of using wood panels behind the gypsum? It's not that difficult to mount things on a gypsum wall, and you end up spending a lot more money and time paneling the walls than it costs and takes time to use a suitable gypsum fastening.
