Hello!
We are in the process of building in a wardrobe in a bedroom here, but before we continue, I would like to check if the soundproofing will work in this room since we have discovered some gaps near the floor.
1) There is a manifold cabinet for underfloor heating between the walls. So it's mostly empty space and a metal door to the cabinet in part of the wall. This should lead to a lot of noise intrusion, right? I will, of course, cover the hole above the floor with plasterboard. But should I also fix the gap even if it will mostly be covered by the floor and the baseboard? How, if so? I have no ideas.
2) There is a gap in the wall between two rooms due to the absence of a sill in part of the wall. The gap is also under the floor/baseboard, but I think it should be addressed? Or is it overkill? However, I don't know how to attach plasterboard since it's also too deep/big for sealant. Maybe some kind of foam?
Feel free to share any tips on materials that work!
