Insulated Plasterboard

[NewhouseOldhouse]

Hi

I am going to dot and dab a garage with insulated plasterboard, should I do this before or after I have my floors insulated and raised?

Thanks

I'd do it after as then the people doing the floors won't accidentally take a chunk out of your newly fitted plasterboard. The plasterboard won't, I presume, be sitting directly on the floor anyway - it's usual to leave a gap between the plasterboard and the floor and cover that gap with skirting.

Plus doing the floor is presumably marginally more complex than dot and dabbing and if the floor ends up needing to go up or down a bit from where it was expected to be, it'll be easier to then work the plasterboard around your floor rather than the other way around.
