benben5555 Posted February 29 Share Posted February 29 Hi, We are moving on to plasterboarding with our build. The timberframers built everything at 600mm centers with no noggins. What have people done in terms of their plasterboard fixing centers? Take the ceilings as an example, one board would touch 3 joists. I could then fix every 300mm down each joist (longways) but there would still be 600mm gaps widthways. Do you noggin across the ends of each board and put another fixing in between each joist making the widthways fixings 300mm centers (at the ends anyway)? Any maybe one noggin in the middle? Just for our first floor this would be 350 noggins! Link to comment Share on other sites More sharing options...
oliwoodings Posted February 29 Share Posted February 29 Some prior discussion here: Use 15mm plasterboard on 600 centres, especially for ceilings. You'll want to hire a lift for the ceilings. Link to comment Share on other sites More sharing options...
benben5555 Posted February 29 Author Share Posted February 29 Looks like the easiest option might be to fit a 25x50mm counter batten at 400mm centers then. Would save cutting a huge amount of individual noggins. Plus I've already bought 12.5mm boards so can't really change to 15mm now. Link to comment Share on other sites More sharing options...

Any pics of the walls/ceilings as is? Lots of insulation, very airtight! That's the plan anyway. I feel on top of that part, just didn't really consider the plasterboard fixings. I've been in the loft of loads of big estate new builds for my job and never seen a noggin. Pretty sure they just fix everything at 600mm centers Link to comment Share on other sites More sharing options...
PNAmble Posted February 29 Share Posted February 29 Probably not very helpful but we air-tested pre boarding at 0.4 ACH. We then built a service cavity frame on the walls attached to the ceiling and floor with 600 centres not piercing the airtightness barrier and boarded on that. noggins only added where specifically needed. We also used a metal suspended ceiling system on both floors to provide a service void for MVHR, pipe work etc. Link to comment Share on other sites More sharing options...
