Bronze has been considered a superior material for architectural elements for thousands of years. Design Synthesis has incorporated this timeless and enduring material into modern fenestration systems, providing the beauty of a natural patina finish with modern door and window functions and the highest energy efficiencies available. We offer all-bronze systems as well as systems that feature a bronze exterior and any wood interior. Styling can be traditional, modern, craftsman, transitional, or can be modified to meet the specific needs of an individual project. Bronze fenestration will raise the level of a home to heirloom quality and the bronze patina finish can be refreshed indefinitely.
