After almost seventy years of service, the city swimming hall has been completely renewed. The glass roof, removed in the 1970s, was rebuilt. The project team focused on the original architecture but was reinterpreting details, material and functions. In order to achieve a maximum grade of translucency, laminated glass elements have been developed with metal strips embedded in the interlayer material. These metal strips couple two laminated glass units together. After the lamination process, the coupling metal strips are to be bent. In accordance with the bending process, the glass elements are shaped and can be installed on site. This final connection detail enabled the design team to reduce the opaque connector line to a minimum.
