Windows aren't just for looking out of anymore.
They can help protect the planet--and your pocketbook.
Through the Energy Star program, if you make changes to your principal residence during 2010 resulting in qualified energy savings, you can take a $1,500 tax credit.
Those changes include replacing old ones that aren't energy efficient with new, Energy Star approved windows, those that have:

• a U-Factor (measurement of heat control of a window, or insulation factor) of less than or equal to.
  30 and
• a solar heat gain coefficient (SHGC) of less than or equal to.
  30 and
• an National Fenestration Rating Council (NFRC) label

Open a New Window Windows can completely change the appearance of your house.
There are a variety of designs, from single-paned casement ones with the hinge apparatus on one side, to awning ones that open from the top.
Sliders are the standard model in American homes, but you can also have double hung windows and designs from arched to oval to octagonal.
Windows don't just change the appearance of your home.
They can also improve security, weatherproof and waterproof your home, and allow you to make your home cooler in summer and warmer in winter while keeping your energy use efficient.
New types of windows exist, from low-emission and gas-filled windows to triple paned glazed windows.
