Versatility in replication and new build, the Berkeley window was originally created in order to replace existing 1920’s and 1930’s steel windows that were predominantly single pane leaded glass, exterior putty glazed. For the Berkeley window, Crittall developed an entirely new series of hot rolled profiles where a solid steel chamfer replicates exterior putty glazing, whilst the interior glazing improves access for reglazing and security.

Berkeley offers an ideal solution for both replacement projects and new construction where minimum sightlines, maximum daylight, and fine detail are desired. The system is suitable for high-end residential, institutional and commercial applications.

Hot-dip galvanized for durability, and in-house Duralife® polyester powder coated for exceptional performance and minimal maintenance during service life, the Berkeley window is available in a wide variety of sizes and configurations to suit any building where strength, combined with slim and elegant frames are required.
