I need to install a lowered ceiling in a 5m square room, to cut down on noise levels from upstairs.
What timbers should I use to span the room? Given that I can't obviously suspend from the upstairs joists as that would simply transfer the noise to the new ceiling.
And also considering a fairly heavy load with minimum 12.5mm plasterboard and at least 100mm of sound deadening material.
Any suggestions welcome
