The windows in my flat do a lousy job of keeping heat in and cold out. Is there a way to improve the insulating properties of window glass without installing double glazing? Ideally it would be something I could install myself (and if necessary remove when I move out of my rented flat.) Googling turned up various window films, both do-it-yourself and have-somebody-do-it-for-you. Any experience with these or similar products? Any other suggestions?
