Energy Retrofit for Old Windows
Open Sash specializes in energy efficiency, weatherization, and restoration of old windows.
An Open Sash energy retrofit turns beautiful quality-made old windows into ones that are as energy efficient as a modern window—at a price that is lower then replacements.
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.
In addition to being affordable our window retrofits are also the most earth friendly, carbon neutral, and sustainable choice you can make.
