The best thing about energy efficient windows and doors is that you can see the difference in your very next utility bill – you’ll be saving money as soon as they are installed.

There are a variety of styles and colors to choose from, including an assortment of decorative elements that can be added to the windows to make them fit the style and décor of your home. . Energy efficient windows and doors can be “double hung”; meaning that they are made up of two sashes – an upper one that slides down, and a lower one that slides up; both of these tilt inward for easy access to both sides during cleaning. “Sliders” are made the same way as the “double hung” except that they slide from side to side, rather than from top to bottom.

Another option for energy efficient windows are “casement”, and these come in a single sash that turns almost ninety degrees to allow the most air to pass through. These three are the most common of the energy efficient windows and doors.
