The Savings Bank in Senftenberg required an even, flat inclined roof. Over the rectangular ground view the girders span over distances of 3,75 m. In order to receive maximum transparency glass fins instead of conventional steel/aluminum purlins were be used for the roof glazing.
The safety glass fins consist of an ensemble of three panes connected with PVB-foil. The glass fins were designed in such a way that even with a collapse of two panes the maximal live load would be carried through the residual third pane. The fins are connected with the  main girder through stainless steel brackets.
