The Diagonal Zero Zero, is a skyscaper in Barcelona, Spain. The building has a height of 110m, with 24 floors, and is located in the city’s main avenue. The project is an example of high-tech architecture. The perimeter structure is split in two rings: an interior vertical structure and an exterior bracing lattice supporting the structural movements produced by wind or earthquakes. Effisus Ecofacade was the chosen solution for sealing the building’s facade connections. Effisus Easyrepair was used to seal the perforations made thought the building’s windows.
