Rest module silentUNIT

Glass Acoustics Module - Rest Module - Sound Screen - Acoustics Module

The silentUNIT glass acoustics system is an acoustic room partitioning system. The quiet modules are ideally suited for the sustainable acoustic refurbishment of open-plan offices. The sound barriers optimise the reverberation time and reduce the direct propagation of sound, so that disturbing speech information is reliably reduced. As a room partitioning system, the rest module divides the space without restricting transparency and open office culture. At the same time, the glass acoustic system is an effective acoustic solution. silentUNIT is a construction of frameless glass surfaces and high-performance absorbers. The glass surfaces of laminated safety glass (LSG) or toughened safety glass (ESG) provide good sound insulation. The integrated high-performance absorbers absorb sound. With the combination of sound insulation and absorption, the rest module optimises the acoustics in the office.

Despite Corona crisis back to the metropolitan area. silentUNIT makes it possible!

If one currently follows the reports in the press and on the Internet, the Corona pandemic seems to make it impossible to return to the open-plan office. From our point of view this is reason enough to take up this train of thought and really think it through. Let us compare the open-plan office, the open space, with the closed forms of cellular office and group office. Doesn't the open office space offer much more space to keep the required minimum distances. We think so! Just think of the cramped encounters in the usual cellular office corridors. Rarely is such a corridor wider than 1.40 m. Here it is simply impossible to keep the safety distance.

But it's quite different in the greater area. Here the areas are much more extensive. The central zone can be used to design traffic routes as one-way streets, so that direct encounters can be largely ruled out. It is much easier to avoid each other. A moderate settlement of the workplaces should therefore be feasible without problems. However, problems could arise at the workplace itself. The usual table blocks of 4 hardly allow the necessary distance. However, a significant increase in the spacing is not recommended for either ecological or economic reasons. Here you should think about the silentUNIT rest module. These glass acoustic screens create the necessary distance between employees and hygienically shield colleagues. At the same time, they eliminate the acoustic problems in open space, in large rooms. You don't have to do without the transparency, the direct visual contact between colleagues. Large glass surfaces maintain this important advantage of open space. Especially in times of required distances, this eye contact is crucial for fast and effective communication. All surfaces are easy to clean and resistant to disinfectants.

Certainly not all employees may be present at the same time, but just when a healthy change from "home office" and "culture of presence", i.e. working in the office, seems necessary and sensible, this open office offers advantages such as desk sharing, agile working and/or territorial working. It is precisely this office space form that allows for all the necessary scenarios to get back to "normality".

silentUNIT macht die Rückkehr in das open space möglich, trotz Corona!

Am Arbeitsplatz selbst könnten Probleme entstehen. Die üblichen 4er Tischblöcke lassen den notwendigen Abstand kaum zu. Weder aus ökologischen, noch ökonomischne Gründen ist eine deutliche Vergrößerung der Abstände zu empfehlen. Hier sollten Sie einmal über das Ruhemodul silentUNIT nachdenken. Diese Glas-Akustik-Schirme schaffen die notwendige Distanz zwischen den Mitarbeitern, schirmen Kollegen hygienisch voneinander ab. Gleichzeitig eliminieren sie die akustischen Probleme im open space, im Großraum. Sie müssen dabei nicht auf die Transparenz, die direkten Blickbeziehungen zwischen den Kollegen verzichten. Große Glasflächen erhalten diesen wichtigen Vorteil des open space. Gerade in Zeiten gebotener Abstände ist dieser Blickkontakt entscheidend für eine schnelle und effektive Kommunikation. Alle Oberflächen sind leicht zu reinigen und resistent gegen Desinfektionsmittel.

Sound barriers reduce direct sound propagation and optimize reverberation time

The acoustic solution supplements only glass walls at acoustically meaningful positions with absorber solutions. These broadband absorbers or high-performance absorbers comply with the acoustic classification A according to DIN EN 11654. The absorbers are therefore highly sound absorbing and significantly reduce the reverberation time. By using silentUNIT as an acoustic solution, office planning achieves a considerable reduction in sound propagation at relevant points and improves room acoustics through adapted solutions. The sound of technical areas, meeting points and work cafés can be effectively shielded acoustically with the quiet modules. The sound shielding of different teams enables spatially efficient and dense office planning without these teams interfering with each other. The open-plan office is held together visually. The visual relationships of the colleagues are consciously strengthened. The character of a modern, open, transparent and communicative office space is retained. The glass acoustics as a room system sustainably improves the room acoustics.

Glass Acoustics reduces the sound level and enables efficient occupancy with optimum acoustics in the office

silentUNIT acoustically and creatively supports your efforts to occupy office space more densely, to design the function of office space efficiently and thus to optimise costs. The silentUNIT glass acoustic system eliminates disturbing sound sources without having to place partition walls in the conventional sense and without forming closed rooms. As a rule, the acoustic sound screen stands across the façade, between the work groups and acoustically separates them from each other. Within the team, the acoustic module reduces the reverberation time and thus the volume.

As a room system, silentUNIT structures the office space and your teams. The highly sound-absorbing A-Class absorbers optimise the acoustics in the office with sound barriers. As a rule, the system is installed ceiling-high, thus guaranteeing maximum effectiveness. In the event that a ceiling connection is not possible, the 3/4-high truss system offers solutions. Last but not least, the acoustic sound screen can be easily electrified and provides the workplaces with energy and data.

Consideration of alternative acoustic solutions for office planning - concept comparison

For some office planners, a closer look raises the question: why not simply install conventional partition walls and create group offices? This would underline the effect of sound insulation even more clearly. The answer is simple. Yes, sound insulation from office to office would be better. However, the acoustics in the group rooms would be much worse. Even the acoustic ceiling as a ceiling absorber could not change this. The syllable intelligibility in a small room can hardly be reduced and will always remain disturbing.

This syllable comprehensibility behaves quite differently in the "noise sump" of a large office area. The spoken word does not carry for a long time so far. Why not simply install ceiling sails or other ceiling absorbers and absorb the sound. Here, too, the answer is obvious. The containment of the disturbing sound sources is then not sufficiently given. Ceiling absorbers alone cannot create optimal acoustic conditions.

Office planning is therefore well advised to rely on acoustically activated room structuring and to adapt this to the requirements of the space. Ceiling absorbers can play an additional role.

space efficiency

The acoustic system optimises office space acoustically, keeps it transparent and enables efficient use. It is flexible for upcoming changes.

room acoustics

silentUNIT creates quieter and transparent office spaces with ceiling sails and absorbers. Teams are acoustically self-contained and can work undisturbed.

Plug and Play

Upon request, the silentUNIT sound shield can be electrified ready for use. Sockets can be built into the absorbers and wired internally.

traverse system

The silentUNIT rest module offers paths for the electrification of workplaces and thus contributes to the more effective use of office space.


The acoustic system is designed as a modular system. It can be installed room-high or under a self-supporting truss.


The resting module is individually designed for the intended use. Among other things, it is adapted to the given room height and furniture formats.
