To acoustically separate the so called Lady’s Chapel, a part of the St. Patrick’s Cathedral, from the rest, seele was assigned with the design, fabrication and installation of the all-glass interior façade. To preserve the visual aspect of the existing structure, the design is perfectly integrated into the building. The special thing about this project is that the approx. 2.5t heavy glass panes are supported solely by a 7m long 8-ply glass beam. In several night shifts, the oversized panes of the Chapel’s glazing were installed with highest precision.
