When installing internal pipework in high rise apartment or multi-occupancy buildings, the use of acoustic drainage is essential to ensure tenants are not disturbed by the sound of running water or vibrations from the pipes. Here, Franz Huelle, Head of Technical for Building Solutions at REHAU explains more about the issues of noisy drainage, options for acoustic drainage pipework and how it can offer major benefits for installers and end users alike:
A complete solution from family homes to large commercial buildings
RAUPIANO Plus pipe, fittings and accessories are available in sizes DN 32 to DN 200 and compatible with HT- and KG systems – offering noise and fire protection.
Premium noise protection –
verified by the Fraunhofer Institute
Quieter than the ticking of a watch: RAUPIANO Plus comes in significantly below the minimum legal requirement for noise protection in sanitation installations. It easily fulfills the stringent VDI 4100 standard.
Even when time is of the essence on the construction site, errors are unacceptable when it comes to fire protection. All REHAU fire protection solutions are therefore designed for easy planning and simple installation.
Eliminating potential sources of errors in the planning and installation, as well as reducing the installation effort required, speeds up installation by up to 30% compared with SML cast-iron pipes..
Flawless installation guaranteed
The toggle latch in combination with a fixed closing distance always ensures the optimal closing force around the pipe, every single time. The specially shaped rubber linings create a self-centreing function of both brackets to each other and therefore the pipe. A uniform space is reliably formed between pipe and brackets which maximises the sound dampening performace.
Passed with flying colours
Achieving noise protection compliance for the entire installation is particularly challenging. In addition to water drainage with RAUPIANO PLUS, the noise tests at the Fraunhofer Institute also included the drinking water installation with RAUTITAN and the sanitation equipment, including the flush technology.
The result: the standard was easily met RAUPIANO PLUS and RAUTITAN offer system-tested noise protection to meet the highest standards.
Our fire protection solutions are approved by DiBT and meet a fire resistance of at least 120 minutes.
100 % Thermal Insulation
Without compromising thermal insulation, REHAU fire protection solutions can even be used in thermally insulated ceilings, e.g. in underground car parks..
Fire stop pipe tape (DN 40 to 110)
Fire stop collars (DN 50 to 125 and DN 40 to 200)
Angled fire stop collar (DN 75 to 125)
Compared to SML, RAUPIANO plus frees up more valuable living space through measurably lower space requirements..
30 % faster installation
Eliminating potential sources of errors in planning and installation, as well as reducing the installation effort required speeds up installation by up to 30% compared with SML cast-iron pipes.
With RAUPIANO Plus, installed costs can be reduced by as much as a third when compared to conventional SML cast-iron and HT plastic pipes..
The cost savings for installation and materials were demonstrated by a large building with 313 residential units. The contractor assessed installation with SML and HT pipes.
Installation times were taken from an external, independent study by Innung Spengler, heating and plumbing technology in Munich.
