Moving large sheets of plasterboard upstairs.

[flutterbye]

Just to say that with help we managed to get the boards upstairs. I checked my "DIY" book again and it did say the 150mm gap at the bottom is to allow for "expansion". Since we're doing with for soundproofing is it definitely the case that I can fit them with a much smaller gap (and perhaps seal with accoustic mastic) ?

I understand books can be a good source of information for the inexperienced but I wouldn’t plaice too much faith on what you read in DIY books.

I assume that’s a typo & you mean 15mm not 150mm. I usually allow around a 12mm (I don’t measure it accurately), which is more than adequate. Like all materials, plasterboard will expand & contract under the effects of temperature & humidity but the amount it will affect the PB & skim will be minimal. The gap is not there to allow for expansion & you definitely don’t need a 15mm gap to allow for it. Having no gap at all will not cause problems, other than a crack where the floor & wall meet which you can seal with flexible caulk if required. A gap is not essential with modern damp proofing methods in ground floors or on first/suspended floors but, as I said previously, it can prevent plaster/PB being damaged in the event of accidental flood. Where is the PB being fitted, are you not covering the gap with, skirting, quadrant or tiles etc?
