On a gigantic surface of 8 x 14 meters a high-quality and hard-wearing stage curtain in wave optics was attached, which fills the interim plenary hall with more optical warmth in its colouring.
For this purpose, we added side wooden frames to a corresponding finished frame and provided it with a "Gerrits Trumpf 95" functional rail on ball bearing rollers. The new wool curtain fabric is flame-retardant and has additional sound insulation properties.
