Where to use foil backed plasterboard

I'm drylining a garage wall that gets quite cold. Is foil backed plasterboard the right choice and does it go foil-side in or out?

"This is not the correct way if you are trying to make the garage warmer…
You will get Cold spots on al areas where you have put the adhesive.
I would recommend studding the whole garage, insulate in between, staple vapour barrier to the stud afterwards and then you will be able to use normal plasterboards."

"You will have to build a stud wall and insulate between the stud works and if you can afford it put insulated plasterboard over. What you have suggested to use is not a good idea

Regards."
