To optimise the room acoustics, two fabric-covered, highly effective fecophon absorber elements were hung in front of the glass. These could also be used as magnet boards. The closed U-shaped fecowand solid walls made of dyed-black, transparently-coated MDF were horizontally slit on the room side in a 14/2 mm grid to render them acoustically effective. In the 105-mm-thick wall, a flush-mounted, frameless fecostruct structural glazing element with a black powder-coated aluminium profile and a 20-mm-thin black adhesive edge was integrated on the door side. Opposite, flush-mounted fecofix double glazing with an all-round 20-mm-thin, black powder-coated aluminium frame formed an economical alternative. The flush-mounted H70 wooden door element with a concealed frame on the corridor side, with its visually-striking smoked oak veneer surface demonstrated the company’s high processing skill at its production site in Karlsruhe where it has its own veneer processing unit.
