Wood Windows and Sash
Cooper Historical Windows
Cooper Historical Windows was built on preserving and celebrating traditional craftsmanship that is vastly fading. With 40+ years of practice, we specialize in historic window restoration and replication of both wood and steel windows.















We manufacture our own flat Liberty Restoration Glass at our CT facility allowing us to build IGUs (Insulated Glass Units) that look antique while offering high energy ratings. We design historically accurate windows with coated Mylar film for climate change that can be directionally tuned to correct all climate concerns. To address sustainability, we use water-based finishes and build our all-wooden windows from Accoya – a renewable plantation pine. Our steel frames have a true thermal break in the frames, and we can offer SDL (Simulated Divided Lite) leaded glass in diamond pane or traditional leaded rectangular glass.
We also offer full removal and installation of our windows anywhere in the USA. Cooper Historical Windows carefully analyzes each window project for the best possible outcome and upgrade for its windows without losing original aesthetics and integrity.
Our work includes Commercial, Residential, Institutional, Sacred Buildings, Museums and Landmarks.
