That's one way of doing it, yes. Another is to use backer rod if the gap is large or deep. A third way is to just caulk each joint once the drywall is in place.When using several layers of plasterboard, do we leave such a gap in the corner for caulk?
Right, but which way is correct or which way yields most soundproofing? If you just caulk each joint, is that as effective as having a gap?Soundman2020 wrote:Hi. Please read the forum rules for posting (click here). You seem to be missing a couple of things!

Both methods work. The difference is in decoupling: if you want to decouple the drywall on one wall from the drywall on the adjacent wall, then leaving a gap and filling it with caulk will help to do that, but it isn't strictly necessary. You'd only need to do that it you were looking for very high isolation, and had taken all the other necessary steps to get very high isolation. So for most home studio builders, decoupling like that isn't necessary , but you can if you feel like doing it.Right, but which way is correct or which way yields most soundproofing?
