OPEN SASH

Open Sash has developed a unique system for adding glass to the existing sash that doubles the thermal resistance of the window without changing the look or function. With the addition of modern integrated weather seals, foam insulated weight cavities, and restoration treatment, your old windows will look great and function as well as a modern window... Our retrofit system can be used on any type of window - from historic to factory modern, single or double hung, casement or fixed. Our energy panels are custom-made to fit your needs... Specializing in window retrofit, energy efficiency, weatherization, and restoration of old windows.
