After examining previous work completed by Colt on the MMC project in Hamburg which used the same design principles, the architect awarded the contract to Colt to supply glass louvre to the atrium in the District Savings Bank Harburg - Buchholz branch.

These are completely pre-assembled profiles with the actuators incorporated into the mullions. The louvres provide ventilation and air flow to the corridors around the atrium, and can be operated from a central control panel, or manually.
