Since the beginning of the nineteen nineties, acoustic solutions have been developed at the Mock-Up in a lively exchange with scientists at the Fraunhofer Institute. It all began with "Profil 22" and "Profil 33", two panel curtain systems with an elegant, pared-back rail system and a curtain material similar to architect's drafting film. This timelessly elegant system is still used today, and what makes it so special is the barely visible microperforations in the film that break up sound waves, thus significantly reducing reverberation time within a room. A panel curtain with drafting film and intelligent acoustic control. "A typical outside-the-box product," as Dietrich Brennenstuhl, founder and CEO of the Nimbus Group, characterises his invention. SUCCESSION OF NEW INSPIRATIONS However, these systems were just the beginning: "We applied the film to a honeycomb material, creating an element that is as light as a feather," recounts Brennenstuhl, who is often to be seen in the Mock-Up, for example giving visitors a tour of his product world or during one of the company's evening presentation and discussion events. In the CP30 system, Rosso offers interior designers a system that can be installed on the wall, ceiling or as baffles in the middle of a room while managing a balancing act between different requirements: it maintains lighting levels and transparency in a room yet gives privacy and is also acoustically effective.
