An extremely advanced facade

The project has been performed by Permasteelisa Group through its subsidiary Permasteelisa North America with the support of other competence centers spread around the world in Europe and Asia. The Group has designed, engineered and produced 8,743 curtain wall panels, with 1,060 different configurations for a total of around 70,000 sqm (753,500 sq ft) of curtain wall. This includes 660 corner panels that were all different from each other as the tower is tapering from the bottom to the top, resulting in several unique panel modulations.

In particular, this façade is characterized by two main typical panels. The vision panels, which are used at the typical office space unit, are equipped with very tall glass that reach almost 6.7 m (22 ft) on the executive floors, and a ventilated spandrel panel cladded by terracotta tiles. There are 34,845 extruded terracotta tiles, with a very specific concave shape and finishing that reflects most of the sun beams during the day, creating amazing reflections. In addition, a special solution was developed for the mechanical floor units, which are equipped with a unique three IGU faces, of which one is recessed from the others in order to allow for natural ventilation.
