You get a wall that feels sturdier, has better soundproofing between rooms, and you can hang heavier objects on the wall.

What thickness is required for the wall or ceiling?
By double board, do you mean 2 x 6 mm or 2 x 13 mm?
Thank you
Olivier

2x6 hardly makes any sense to use, so 2x13 (usually it's actually 12.5mm) is what is meant when referring to double plasterboard.

Same thing with the ceiling, normal plasterboard (12.5) is usually used there as well.

Many, or almost all, lay the gypsum along with the framework and that's wrong..
so if you, for example, have 90x240 gypsum then most people space the studs at cc 45...
But in reality, you should space the studs at cc 40..so that you're screwing into 6 studs instead of 2 studs...
when gypsum boarding walls, you lay the board in the opposite direction...

When I did my roof, it was supposed to be CC 30 according to what I found. But it may have changed.

cc 30 is probably not entirely wrong... if you use 2 layers you can space it wider..
I've also installed perforated gypsum where it had to be cc60... but then you had to have T-splines in the joints..
