    NZR Windows & Doors completed a planned upgrade at SupaJam School in Swanley, Kent, replacing the existing steel Crittall windows with new white uPVC window units. As part of the same package, we installed a new back door combination and completed making good throughout to ensure a clean, consistent finish internally and externally.
