In the next week or so I'm going to get my bathroom wall

I take it that there will be no problems doing this and is it the same
stuff that gets used for loft insulation I should be using .??
I'll be securing it (at the top at least) to stop it slumping down .
You'd be better off using Kingspan or Celotex rigid insulation boards;
they are much more efficient than fibreglass wool, so you'd need much
less thickness to achieve the same level of insulation. (They also lend
themselves to insulating vertical surfaces!). How deep were you
proposing to make your battens? Hope you have a big bathroom...

I've got enough trouble getting 8' x 4' p/board up 2 flights of stairs
without adding to that problem with other boards .....The batten faces
are about 40mm off the wall........the bathroom is about 4.5m x 1.4 m
but why did you ask that ??

ps..when I said before it is an exterior wall ,it's actually on a
staircase so it's not totally exterior but it is still cold but not
affected by ,for example,rain..

At that depth use celotex/kingspan.

If you use the foil tape to secure it to the studs, you won't need foil
backed plasterboard. Mind you belt and braces...
