Insulation over drywall??

We remodled a 1950's house and in our master bedroom built an extra closet that protrudes out from the wall . I have noticed that inside this closet as well as the whole wall that it was built onto stays particularly cold in the winter and hot in the summer. Is there any type of insulation that I can put over the existing drywall and then paint over,. I hate to pull the drywall down as we replaced all of it too during the remodeling.

Maybe install a sheet of foam insulation and then cover that with drywall ??

Rigid foam would be the only insulation I'd use over drywall.

Is this a walk-in closet? If so, I think the best solution is to put a vent from your HVAC system in there.

You may have a problem with condensation and mold, if you leave any gaps or cracks in the sheet foam insulation.
Remember water vapor always moves to cold - it would be better installed on the other side to ensure the room side is kept warm and dry.
