Fittings. Pipe bends pose a hazard, as the sudden release of water causes vibrations in the pipe walls. This can negatively impact the acoustic properties of the pipes. To minimize this effect and avoid negative impacts, mass reinforcement has been implemented in critical areas of bends with diameters from DN 90 to DN 125. This stabilizes the acoustic properties, reducing sound propagation and thus achieving higher sound absorption in the impact zone.

The RAUPIANO PLUS sound-absorbing drainage system guarantees quality, peace of mind, and comfort in one of the key areas of internal engineering systems.

Functions. RAUPIANO PLUS is a universal, soundproof, gravity-fed drainage system for indoor and underground installations. This versatile drainage system is used in both single-family homes and multi-story buildings. The system offers a wide range of accessories and fixings.

• High quality and attractive design
• Excellent sound insulation
• Patented REHAU fixing clamps reduce sound transmission through building structures
• Sound-insulating material for pipes and fittings
• Improved sound insulation at bends thanks to partial wall thickening
• The optimally smooth, wear-resistant inner pipe layer reduces the risk of blockages
• High impact resistance at sub-zero temperatures and strength retention down to -10°C
• High UV resistance; allows installation on external supports, with a service life of up to 2 years
• High impact resistance: resistant to mechanical stress during transport, storage, and installation

Residential construction. RAUPIANO PLUS is a universal gravity drainage system for installation in buildings, both in standard drainage systems without special sound attenuation requirements and in those with enhanced sound attenuation requirements (VDI 4100).

For example:

• Single-family homes
• Apartment buildings
• Townhouses

Large projects. RAUPIANO PLUS can also be used in large projects with higher sound insulation requirements (VDI 4100). Thanks to its excellent sound insulation properties, the RAUPIANO PLUS system is widely used in:

• Hotels
• Office buildings
• Hospitals

RAUPIANO PLUS meets the growing need for quiet and provides high acoustic comfort.

Underground pipe installation. The RAUPIANO PLUS system is approved for underground installation, both indoors and outdoors.

Kitchens. The RAUPIANO PLUS system is suitable for grease collection and drainage pipes to grease traps in kitchens. If the grease traps are located in distant areas, it may be necessary to install heating pipes. This facilitates the removal of grease deposits. The temperature of the heating pipe material must not exceed 45 °C.

Application in ventilation systems. RAUPIANO PLUS can be used in single-family and duplex homes for centralized and decentralized air extraction from bathrooms, toilets, and kitchens. There are no special fire protection requirements for this type of building. In particular, for bathrooms and/or toilets located one above the other, we recommend using the RAUPIANO PLUS DN 110 pipe as the collection duct for air extraction.

Central vacuum system. Thanks to its excellent sound insulation properties and smooth inner layer, the RAUPIANO PLUS system is ideal for central vacuum systems. REHAU offers the VACUCLEAN central vacuum system, which consists of a central vacuum unit, pipes and fittings, fixings, and suction inlets.
