To Insulate behind Aquapanel (Or Not)

[RustyScot]

Greetings to all,
I'm about to start rebuilding my bathroom after finding some serious water ingress into the plasterboard. The house is a 1970's ex-council mid-terraced and the wall in question is between me and a neighbour, I've got a stud frame about 5" deep on top of a brick wall with no insulation at present. Should I put insulation in before I put up the Aquapanels and if so what type?

Thanks for reading this far

If you like the thought of your neighbour listening to you in the bath or on the loo, then no dont insulate. IF like the majority of the world you dont relish the thought of being overheard having a long think then stuff as much insulation into the wall as possible.

Thanks for the advice static,
There hasn't been any insulation in the wall for the last thirty odd years and no so far.
