The RAUPIANO PLUS Acoustic Plumbing and Drainage System is a polypropylene-based plumbing and drainage pipe system that consists of discharge pipes and fittings that have been acoustically designed to reduce the noise caused by water and waste passing through the discharge system. The system is for use within multi-floor buildings such as, offices, hotels, or residential buildings where noise is an issue. They are also suitable for trade waste such as from commercial kitchens. The pipes are suitable for use both above and below ground. The pipes and fittings are white with a pink and a green stripe.
Multi-layer pipe construction increases the pipe rigidity and enhances the sound insulation properties.
Impact-resistant outer layer provides robustness for handling on construction sites.
The RAUPIANO PLUS system contains no toxic materials and is 100% recyclable (including PVC adaptors).
RAUPIANO PLUS Pipes
Multi-layer pipe construction achieves superior performance through the application of distinct functional layers. Combined in a composite construction three separate layers impart unique characteristics on the pipe.
The abrasion-resistant, low friction inner layer ensures the easy transit of waste.
The mineral-filled mid-layer ensures superb sound dampening properties and offers increased stiffness.
Robust outer layer is tough enough to withstand impacts and shocks.
Combined together, the composite layers create a tough, durable pipe, with outstanding acoustic properties that gives all the functionality of a drainage pipe system combined with the noise insulating properties of lagging.
RAUPIANO PLUS Fittings
The pipe system can experience local vibrations at redirections due to critical drainage conditions, which can have a negative effect on sound performance. Targeted mass optimization of this effect was carried out in sound-critical areas of elbows with a nominal width of DN 90 to DN 160. This stabilizes the sound behavior, reduces sound generation and thus achieves even better noise dampening in the impact area.
Approved fire collar solutions for RAUPIANO PLUS pipe are available.
The system is suitable in a wide range of buildings from comfortable homes, modern hospitals, and hectic commercial kitchens to contemporary skyscrapers.
The RAUPIANO PLUS Acoustic Plumbing and Drainage System has been appraised by BRANZ for use within the following scope:
as pipes, fittings and materials for sanitary plumbing system design and installation in accordance with NZBC Acceptable Solution G13/AS3 and AS/NZS 3500.2; and
for use as a sanitary plumbing system for internal use within buildings; and
for pipes and fittings of size 40 mm and greater, for drainage system design and installation in accordance with NZBC Acceptable Solution G13/AS3 and AS/NZS 3500.2.
Limitations on Use
Installation of components and accessories supplied by Rehau Ltd must be carried out only by licensed and registered plumbers and/or drainlayers.
Statement of Building Code Compliance
In the opinion of BRANZ, The RAUPIANO PLUS Acoustic Plumbing and Drainage System if designed, installed, used and maintained in accordance with the statements and conditions of Appraisal 809 (2013), will meet the following provisions of the NZBC.
Clause B2 DURABILITY: Performance B2.3.1 [a] not less than 50 years, and B2.3.1 [b] 15 years, and B2.3.2. The RAUPIANO PLUS Acoustic Plumbing and Drainage System meets this requirement. See Paragraph 8.1.
Clause F2 HAZARDOUS BUILDING MATERIALS: Performance F2.3.1. The RAUPIANO PLUS Acoustic Plumbing and Drainage System meets this requirement and does not present a health hazard to People.
Clause G13 FOUL WATER: Performance G13.3.1 and G13.3.2. The RAUPIANO PLUS Acoustic Plumbing and Drainage System meets these requirements. See Paragraphs 7.1 to 7.5.
Other Performance Attributes
Acoustic Performance: REHAU RAUPIANO PLUS system has been independently tested by members of the Association of Australian Acoustical Consultants (AAAC).
The System exceeds the Rw + Ctr 40 requirement of the BCA/NCC in habitable areas, and that
An un-lagged RAUPIANO PLUS system is comparable in sound performance, to a fully lagged PVC system.
Temperature and Chemical Resistance: RAUPIANO PLUS has a high temperature resistance of 95 degrees (intermittent) and 90 degree (continuous operation) as well as a broad chemical resistance to aggressive waste.
Environment: Made 100% Polypropylene which takes comparatively low energy to manufacture. PP is also 100% recyclable and contains no harmful chemicals. Using PP drainage reduces the amount of PVC within a project which can award valuable credit points towards the buildings green star rating. RAUPIANO PLUS also requires no toxic glue or primer during installation.
Fire Resistance: For fire protection of penetrations through fire-rated ceilings and walls, it is compulsory to install suitable fire collars that will not reduce the fire rating of the particular building elements. RAUPIANO PLUS system can be installed with suitable fire collars which have been tested and proven according to AS 1530.4 to fulfill the fire protection requirements.
