re: Tips on Insulating a Cold Room?

How big is the room? Is it drywall or paneling? Just curious because I added some of the rolled insulation in a bathroom that is at the outer wall of our house when I was doing a renovation. Stuff is cheap. Staples into place. If you have paneling it might be fairly easy to pry it loose, staple up some insulation, and hammer it back in place. Drywall would be a bigger job, but for one room it isn't that bad.
