Including the completion of the second construction phase in June 2021, approximately 620 heroal systems will have been installed in the ”Revaler Spitze”. Hence they shape the view of the new building to a great extent. In close cooperation with the builder owner, the contractor, the window company Wagner, chose the curtain wall system heroal C 50. This curtain wall system combines sustainable construction with freedom of design. Through innovative design details, heroal C50 offers a filigree look while at the same time achieving excellent heat insulation values, which, with a building of this size, lead to considerable savings of energy and costs, and have a positive effect on the energy balance. The individually designed curtain wall system grants the building shell an impressive character: derived from the steel profile frame look of the early 20th century, the curtain wall system has an anthracite grey heroal hwr powder coating that further underlines the industrial charm of the building.
