The interior spaces focus on this central, brightly-lit connecting element that opens up the individual levels and functional areas both vertically and horizontally. The fecoplan all-glass construction as fall-arresting glazing enables exciting visual relationships and, with a sound insulation test value of R w,P = 42 dB, also a high degree of confidentiality. The other consulting rooms and offices are equipped with fecofix flush-walled double glazing with R w,P = 47 dB with all-round 20-mm-thin frame profiles. Double-sided flush H105 wooden door elements with concealed corridor-side frames achieve a sound insulation test value of Rw,P = 42 dB. In keeping with the restrained colour concept, the wooden doors are granite black and the aluminium profiles white powder-coated. Brightness and clear shapes radiate a pleasant and open atmosphere, which is experienced as friendly by both customers and employees.
