This MUST have been answered before, but I simply can't find it. I have put up drywall on an existing panel wall to simplify wallpapering. Ceiling height is 242 cm and the drywall is 240 cm. What do I fill the gap between the wall and the ceiling/floor with, considering future cracking, soundproofing, etc.? A trim will eventually cover the joint (probably in about a year...

But it's not open, there must be a rule behind the plaster.
Filling in the small gap doesn't make a difference.

how is the wall constructed? is it a sound barrier or a solid wall screwed/nailed into other walls/floor? if it is a sound barrier you should use acoustic sealant. but I would recommend double layers of plasterboard then.
Unfortunately, it is not a sound barrier, but I am unsure about the construction. In any case, there is paneling on the outside on both sides of the wall. The paneling does not go all the way down to the floor or all the way up to the ceiling.
If this is someone's home, I think the whole thing feels overly paranoid; sound doesn't transmit that badly. Do you have studs with rubber strips? Do you have double drywall? Good insulation? Such things play a bigger role than whether the panels are against the ceiling and floor. If anything, sound transmits through the panels and the framework, not through the ceiling and floor beams.
As long as no inspector comes with a dB meter, I think you should let it be; the moldings will cover it.
