Our 40 years of custom window and door fabrication has been a constant evolution. Throughout the years, each material that we work with takes us forward to added skills and precision in our overall approach to our craft. Jada thermally broken steel is a fabulous merging of old world steel window designs with new world performance and technology. The role of the window craftsman has become a broad spectrum of talents from skilled fabricator to design engineer to thermal scientist. Our modern adaptation of energy efficient steel windows and doors has opened the way to many innovations in the expanding world of fenestration.

Our focus is to maintain a consistently narrow form throughout a variety of product applications. Today’s custom estate architecture calls for a comprehensive range of swinging, sliding, folding, and pivoting windows and doors while maintaining proportion and sightlines. Each aspect of our product–from materials to finish, to hardware, to glass, to integration into the building envelope–is a study of its own. We feel that our continued focus on this level of detailed design and product development best prepares us for the future demands of our clientele.

This website is intended to show the details and possibilities of this innovative thermally broken steel product spectrum. The effort it takes to continue this evolution requires our team of dedicated craftsmen. We introduce some of the key staff members below, but many others also make this happen through their skills and talents. Call and arrange to meet us in person if you are going to be in the Grass Valley-Nevada City area.
