Geberit Silent-db20 Drainage system with high sound insulation
Whether in a residential complex, a hotel or a meeting room, noisy discharge pipes can be a nuisance. This is where the Geberit Silent-db20 drainage system eliminates the issue before it starts.
This highly sound-insulating drainage system is suitable for both stacks and floor connections, ensuring quiet and efficient drainage in any building.
What’s more, the system is also suitable for prefabrication.
Why choose Geberit Silent-db20?
Highly sound-insulating piping system
The high inherent weight means that its natural vibrations are reduced and any sound is noticeably absorbed.
Non-positive connections
Geberit Silent-db20 can be connected using butt welding or electrofusion couplings.
Suitable for prefabrication
Off-site prefabrication for cost-effective and safe system construction.
High discharge capacity with reduced space requirements
Hydraulically optimised for greater cost-efficiency, reduced space requirements and a high discharge capacity.
Main applications and areas of use
Buildings with high sound insulation requirements
Geberit Silent-db20 can be used for both stacks and connection pipes in various types of buildings with high sound insulation requirements.
High-rise projects with SuperTube technology
Geberit Silent-db20 SuperTube is a space-saving drainage system that’s ideal for projects with high sound insulation requirements.
Prefabrication
For larger construction projects, system structures using Geberit Silent-db20 can be easily prefabricated at the workshop to save valuable time on the building site.
Laying in concrete
Geberit Silent-db20 is suitable for embedding in concrete slabs. This application requires the use of non-positive connections.
Projects with fire protection requirements
Fire tests were carried out in accordance with the EN 1366-3 standard for a wide range of different installation situations. In combination with the Geberit fire protection sleeve RS90 Plus EN, the Geberit Silent-db20 drainage system is approved for a fire resistance of 90 minutes (ETA/ETB).
Benefits of Geberit Silent-db20
The high inherent weight of Geberit Silent-db20 pipes and fittings means that their natural vibrations are reduced and any sound is noticeably absorbed.
Special sound insulation ribs reduce noise development at the impact zones.
This makes Geberit Silent-db20 a strong choice for stacks and connection pipes in building drainage systems with high sound insulation requirements.
Sound insulation reports for various construction scenarios have been prepared in cooperation with the Fraunhofer Institute for Building Physics (IBP). These are also available for Geberit Silent-db20.
Connection technologies for Geberit Silent-db20
Whether using fast electrofusion welding or butt welding, Geberit Silent-db20 pipes and fittings can be securely connected using three different methods. In some countries, clamping connectors may also be used. A range of Geberit tools and accessories is available to ensure easy processing.
Double-flange expansion sockets and double sleeve couplings help compensate for the thermal linear expansion of Geberit Silent-db20 pipes and fittings. This allows the system to accommodate significant variations in operating temperatures. The EPDM seals play a key role in the long service life of the drainage system.
Geberit Silent-db20 is also suitable for prefabrication, enabling faster and more efficient workflows that are independent of progress on site. This significantly shortens the on-site installation time.
Geberit Silent-db20 is the ideal piping system for embedding connection pipes in concrete slabs, allowing for greater freedom in bathroom design. When working with concrete, non-positive connections are essential.
Tension-free installation despite axial offset Geberit Silent-db20 Offset
It is not always possible to avoid inaccuracies during construction, but when discharge pipe connection points are not perfectly aligned, this can cost plumbers both time and patience. With the Geberit Silent-db20 Offset fitting, stacks can be connected efficiently and tension-free, even when alignment is less than perfect.
Benefits of the Geberit Silent-db20 Offset:
- Tension-free installation for axial offsets of up to 10 cm
- Familiar, easy installation
- Reduced installation time compared to using two 45° bends
- Flexible adjustment with a single product
- Improved sound insulation compared to conventional connection correction methods
