The glazed blocks of the complex (certified LEED^® “Core and Shell” in Gold class) are set around the inner courtyard. The study of the envelope and the “suspended boxes” (for a total surface of about 12,000 m²) required particular care. It included different types of façades, based on the geometrical coordination of elevations, openings, internal and external levels. The main cladding system is the SSG unitized curtain walling with double glazed units and aluminum profiles.

Decoral^® Group has applied RAL 7021 matt Class 2 powder coating to the aluminium frames.
