Hi all,
I've half a ceiling to board, wanting to cut sound transmission as much as possible
- joists are 5", max span is a little under 2.4m, joist centres are varied - up to a max of 550mm (however, there are regular 1200mm centres)
-These joists support the ceiling only - no live load (floor above on separate set of joists)
-I'm using 15mm plasterboard 1.2m by 2.4m
-the ceiling will be professionally skimmed
Am I better running the boards across or along the joists? (If across then I've little or no space for noggins for board edges between joists in the centre, as I'm weaving insulation between the 2 sets of joists)
If running across joists I assume I stagger board ends?
I'm probably overthinking as usual - thanks for your patience!
cheers, Stephen
