Hi, I want to put up 2 layers of 12.5mm plasterboard on a party wall. I'm not sure if to/how to, stagger the screws. Do I screw the first board in every 20-30 cm and then do the second one on top the the same frequency OR do I put enough to hold the first in place then then screw both layers together every 20-30 cm? Thanks.

the second option sounds the most reasonable.
just out of curiosity, why the two layers?

For sound proofing. I took the first layer down and replaced the original 10mm loft-style insulation with 100mm rockwool slab, now replacing the board I've seen several sources a second layer can help.
Its a small room already so I couldn't afford the space for a second separated partition...
