The large-scale format was specified with laminated safety glass. Glass Production Partner Seele/Sedak supplied the multi-functional insulating glass with this impressive dimension. The window, which weighs over 8,150 lb, alone, was installed with special tools. The glass was transported to Doha by ship as it would not have withstood the pressure differences present on an airplane. All other parts of the descending wall were shipped to their destination on the Arabian Peninsula by air freight.
In order to be able to withstand the high wind loads, a special composite construction was developed for the descending window. This ensures that the descending wall will operate operates perfectly even under high wind loads.
Martin Kollegger and his team took care of the installation, which was completed in about three weeks.
