Following an error, I would like you to tell me, by email, how to "stick" an insulation (kind PSE + plasterboard) on a wall already covered with plasterboard (13 mm), so square!

You do not specify what "error" you have made... The bonding of a doubling to a plasterboard, with or without insulation, can be done in principle using any glue for doubling, subject to that the plasterboard is in the raw state.
