After examining a number of samples, SPSG and their architects chose SCHOTT’s acclaimed restoration glass GOETHEGLAS for the project. As well as offering an irregular ‘wavy’ surface in keeping with the style of a 19th century palace, this robust, thermally toughened glass can be produced in large formats.
For the Palace windows, SCHOTT produced three-meter-long glass sheets, refined by thermal toughening and subsequent heat soaking tests. This enabled a large share of the all-glass windows to be installed. The 4.5-meter-high special formats were designed as laminated panes with butt joints. Insulating glass was also produced to address specific climate concerns, made with an outer pane of GOETHEGLAS and an inner pane of float glass.
