Interior walls, which option?

[Mjolnir]

Hi,

Renovating a 90s house with 9 mm particle board/building board on the interior walls.

I was thinking of either:

1) removing the particle boards and installing new gypsum (to completely get rid of the wood/masonite smell, even if it's slight),
2) or screwing renovation gypsum onto the board,
3) or applying renovation wallpaper on the board,

All interior walls have been wallpapered previously, the idea is to get a nice surface for painting and strong functional walls.

Which option would you choose and which is considered the best? The time and effort required are of less concern.

1. Screw standard drywall over the chipboard. 9mm chipboard is sufficient for most things you hang on the walls, making it a really sensible wall.

2. Renovation drywall if, for some reason, regular drywall is highly unsuitable, but I avoid it when possible.

1. Screw standard plasterboard over the chipboard. 9mm chipboard is sufficient for most things you put up on the walls, making it a really sensible wall.

2. Renovation plasterboard if, for some reason, it's significantly unsuitable with the regular, but I avoid it when possible.

Thanks, the only tricky thing with regular plasterboard is that it extends more from power outlets, window recesses, and ends up close to the district heating pipes in the floor, etc. Hence the idea of renovation plasterboard, unless the chipboards are removed and replaced with regular plasterboard only.

Thank you, the only tricky thing with regular drywall is that it extends more from the electrical outlet, window frame, and ends up close to the district heating pipes in the floor, etc. Hence the thought of using renovation drywall, unless the particle boards are torn out and replaced with regular drywall only.

I don't understand what role the pipes in the floor play here but I THINK the advantages of standard drywall are worth the little extra hassle, if there's any at all. Adding 6 or 12mm doesn't make a difference to me.

For the electrical outlets, you can use extension rings if you want to do it right but I must admit that I have sometimes just used longer screws for the outlets and that works fine too

Thank you very much, what advantages do you see with standard gypsum compared to renovation gypsum, other than that it is thicker and probably stronger and more insulating? Are there other advantages?
