Berkeley Series

The Crittall Berkeley series was originally created to replace existing 1920s and 1930s steel windows that were predominantly single pane leaded glass with exterior putty glazing. For the Berkeley window, Crittall developed an entirely new series of hot rolled sections with a solid steel chamfer that replicates exterior putty glazing, with interior glazing beads that improve security and access for re-glazing.

Crittall 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.

Materials and Finishes

All Crittall windows and doors are hot-dip galvanized to ASTM A 123 (BS EN ISO 1461:1999). The units are entirely immersed in molten zinc resulting in windows and doors that are completely protected against corrosion.

Hot Dipped Galvanized Steel

The hot- dip galvanizing process provides corrosion protection to mild steel components by coating and chemically bonding pure zinc to the steel substrate.
