Hi. After originally thinking that I was going to re-board my bathroom in moisture resistant plasterboard (other side of studs are boarded in 12.5mm sound panel) and tanking it, I've seen that most tilers are starting to recommend the foam-type backer boards instead, such as Abacus Elements or Wedi Board so I'm thinking of going down that route now to save any problems years down the line with moisture ingress etc.
However, my 2.4M tall stud wall has 400mm centres with two noggins placed equi-distant between top and bottom (which has been OK for plasterboard) but the foam boards appear to be 1200mm x 600mm in size, which would result in some of the edges not having anything behind them.
I was looking at the 12mm thick variants, would this be a problem or are the boards stiff enough to not cause an issue ? I don't want to spend upwards of £500-£600 on the kits only to find that they aren't suitable for what I want to do.
TIA as always.
