Tools to help you pick your energy-efficient windows | 30 Mar '07 from the editors
Replacing old windows with new, high performance, energy-efficient windows can be pricey. And, once you do decide that the long-term energy-savings are worth the initial investment, swapping those single-paned energy-suckers with dual-pane (or even triple-pane!) replacements can be a complicated process. The options are endless. Do you want the window glass (called glazing) clear or with a bronze tint? Do you want aluminum framing or wood ... or maybe even a hybrid composite? And what type of gas would you like between the panes? Argon or krypton? And how about a low-E coating? It's almost as complicated as ordering a double, half-calf, non-fat, vanilla latte at the corner Starbucks. But, it's worth it!
