In the house I'm living in, which was built in a transition point between making sure houses don't leak and the realization that you then need active ventilation, I have the problem that the windows are not insulating enough, so I end up with water condense on the inside when it's freezing outside. If you are going to replace the windows, I would definitely buy triple-paned, unless you only have a small temperature difference.
