The metal works were carried out by the French metal construction company ATALU SAS. The aluminium systems supplier heroal supplied the system "The demands on building shells have dramatically increased in recent years. Modern, future-oriented projects such as the Elithis Tower place the highest demands on heat insulation, aesthetics and workmanship. These can only be achieved through strong partnerships," says Julien Rohmer, Managing Director of ATALU SAS.
Almost 300 elements of the heroal W 72 window system were used in the sheet-metal cassette curtain wall. Especially narrow view widths were important to the property developer - an individually adapted solution that blends in perfectly with the building shell. Thanks to highly thermally insulated composite profiles made of aluminium half-shells, polyamide insulating webs and a completely foamed insulation zone, the heroal W 72 window system achieves a Uf value of up to 0.93 W/m²K with a frame depth of just 72 mm. At the same time, the innovative web geometry makes the time-consuming and material-intensive use of frame and glazing rebate insulation unnecessary. The modular design leads to an optimal use of energy and materials and thus to maximum energy efficiency throughout the entire useful life. In order to offer the residents a special view of the newly landscaped harbour district, the roof terrace was also equipped with large glazed areas. 30 lifting-sliding elements of the heroal S 77 SL system were installed here.
