feco-feederle supplied the system partition walls for the cubic structure. In order to achieve maximum transparency with high sound insulation, the fecofix partition wall system was chosen as room-high, flush-mounted double glazing with a sound insulation test value of R w,p = 47 dB. Discreet, 20-mm-thin aluminium profiles give the rooms the right frame. The solid wall with a melamine resin direct coating in premium white is also used on the upper three floors as a corridor and office partition wall with 47 dB and with increased requirements 52 dB Rw,p . The H60 wooden door elements veneered with American oak add a warm touch to the white solid wall. The doors with a sound insulation test value of R w,p = 40 dB are flush-mounted on the corridor side with a 18/50 mm anthracite-grey frame mirror and integrated door-leaf top panel.
The striking three-storey glass facade towards the square makes the interior visible to the public. This means the design requirements are very high, but feco-feederle easily meets them with the high-quality workmanship of its feco system partition walls.
