seele has designed a 1,600sqm cable net façade, tensioned around the corners, which is one of the largest of its kind in the world. The exceptional dimensions of the façade called for innovative solutions in terms of structural engineering, cable tensioning and flexural stiffness. For example, the façade had to be designed for wind-induced deflections of ±1.10m. seele developed a solution that complies with all the architectural stipulations of the client, takes into account the temperature differences between erection and completion and also preserves the purist aesthetics of the façade design.
seele also produced thousands of square metres of special glazing for the floors, suspended ceilings, lift shafts and bridges for this project. Many of these bespoke products have been used in the lobby of the stock exchange: mirrored panes combined with rolled glass, translucent PVB interlayers for creating an opaque look. The anti-reflective glass held in place by point fixings at the joint intersections is hardly perceptible, resulting in an almost dematerialised structure in certain lighting conditions. The diffuse, even illumination in the lobby is achieved with LED lights mounted behind the panes. And the floor elements spanning 1.5m without support and made from 4-ply laminated glass – some panes with finely ground stainless steel sheets between the plies – represent another first-rate glass solution by seele.
