Help with building an internal wall

[Dr Fozz]

45mm steel studs with CC45 and then http://www.xella.dk/html/den/dk/fermacell_forside.php fermacell boards to get the thinnest possible wall that still allows you to screw things up. Chipboard is not great as it dampens sound poorly and is bad at resisting fire.

You should not wallpaper on chipboard, you need to have drywall! Otherwise, the wallpaper will come off.

My entire upstairs was renovated in the 80s and only has chipboard+wallpaper on all the walls. No wallpaper has come off.

My entire upper floor was renovated in the 80s and only has particle boards+wallpaper on all the walls. No wallpapers have come loose.

I agree, our house was built in '86, particle boards and wallpaper.

you can use 45x45 and glue + screw chipboard or OSB to the studs, then Rotgips (6mm), and you will get a really stable wall if you glue between chipboard and drywall as well, it probably won't flex much..

If you only have chipboard on the walls, doesn't it move so much that it becomes a problem? I see that byggelit recommends a 2 mm expansion gap between each panel. If you fill this gap with putty and paint directly on the wall, there will likely be cracks before anyone even has time to say the word failure?

Fill this expansion gap with acrylic sealant?

It hasn't cracked yet on our interior wall we built about 5 years ago, 13mm chipboard+45x70+13mm chipboard.

What size expansion joints did you use if you used any, and what did you put in them if so?
