Deceuninck Genius Interlinked Dual Sash Window

Deceuninck North America’s Genius system is the world’s first interlinked dual-sash window that enables thermal performance values exceeding R-14 without the use of exotic films or gasses. The patent-pending system is designed with two separate, interlinked insulated glass sashes, which creates bonus air space between the two sash members and results in an extremely effective barrier to thermal energy flow. Genius also features a thermal-activated ventilation system that automatically vents solar-heated air into the interior in the winter and outside in the summer.
