A radiant barrier probably isn't going to help much. Your biggest window losses are air leaks and conduction through the glass (especially if you have single-pane windows). A better cheap/free solution is bubble wrap. Tape it to reduce air infiltration, and it still lets a good bit of light through. Also some good insulating drapes for nighttime.
