The large-scale format was realized with laminated safety glass. Production partner Seele/Sedak supplied the multi-functional insulating glass in this impressive dimension. The window, which weighs over 3700 kg alone, was inserted using 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 descender front were shipped to their destination on the Arabian Peninsula by air freight.
In order to be able to withstand the enormous wind loads, a special composite construction was developed for the descending window. This ensures that the descender front operates perfectly even under high wind loads.
Martin Kollegger and his team took care of the installation, which was completed in about three weeks.
