Energy-efficient replacement windows pay for themselves in energy savings!
The good news is that replacement windows are the most cost-effective home improvement you can make. The reason for this is that they start paying you back immediately.
Glass is a very poor insulator, but it makes an excellent window. The insulation in a window is actually Argon gas that is trapped between the panes of glass.
