No truth to that mate, condensation is the majority of the time due to a lack of air circulation, and damp will come through whether you you use plasterboard or anything else, if there is a dampm problem to begin with

The only time you need mechanical fixings on plasterboard is if it’s PIR thermal board. Each board requires two fixings only. This is to meet the fire regs.
Yes, condensation is usually formed in houses with solid wall construction (no cavity) due to the humid air inside touching the cold walls.
Plasterboard on external walls actually stops this but you do need a vapour barrier.

So no fixings when dot and dabbing over plaster skim or scratchcoat then ? :|

I’m not entirely sure. I tend to knock back to block/brick.
I suppose the PIR board is pretty heavy and perhaps the foam is flammable so the board doesn’t want to fall off the wall in the event of a fire.
I was told it was to stop fire spreading too so the mechanical fixing might not be a bad idea against skim/scratch. The bond against a block wall is pretty much guaranteed so no mechanical fixing required.
