Windows, doors and skylights equipped with electronically tintable glazing allow the end user to vary the amount of tinting in his or her window with the push of a button. Commercially available in Velux skylights, SageGlass can be darkly tinted when the sun shines brightly, and remain clear on cloudy or rainy days.

Used in fenestration products, the switchable glazing reduces energy consumption and lowers energy bills, as well as eliminating glare on computer and television screens. It provides a more even temperature throughout the home and dramatically reduces fading of furniture, fabrics and artwork. The glazing also increases security of the home, as breakage in the glass can trigger an alarm.

Traditional methods of controlling unwanted glare and heat entering the home include shades and blinds. However, when these are in use, the very reason for the windowthe viewis lost. With electronically tintable windows, all of the above benefits can be enjoyed without ever losing the view through the window. The electrochromic technology has been undergoing testing by the U.S. Government and independent third parties for more than seven years. Results of these tests show a lifetime of operation of more than 20 years. The glazing can be fabricated as a standard dual-pane unit or laminated for safety applications. Once installed, the window or skylight can be operated using a wall switch, remote control or central energy management system.
