Material for Windows

"Although your picture window is a large glass window, you can be confident that you're still saving money on energy bills. The FIBREX frame is strong and energy-efficient. The glass, double-paned, argon-filled, with a Low-E4 coating - keeps your home the temperature you want. You'll be comfortable all year long while saving money on heating and cooling."


This description, taken from Mr. Rogers' Windows, shows that the materials of this window design are energy efficient and "green".  The windows are also large enough to let sunlight in during the colder months to provide for a means of more natural heating and light source.
