Current urban living environments require that more people are living in close proximity to each other, as councils and town planners promote the intensification of apartment-style living to allow for a rapidly growing population. Communal living requires specifiers to focus on reducing noise in these intimate environments, to increase the comfort and wellbeing of the occupants.

To assist with this noise-reduction initiative, Marley offers the Poliphon Sanitary Acoustic Plumbing system, which has been specified and installed into buildings throughout New Zealand. The Poliphon system features a three-layer, PP-MD (modified polypropylene) co-extruded pipe, a range of fittings and acoustic pipe clips. This BRANZ-appraised system has been shown to reduce the noise generated by waste water flowing inside pipework to a level of 20dB.

Additional benefits of the Poliphon system are that it is lightweight, resistant to temperature change and can be installed at temperatures below -10°C. The polypropylene pipes, combined with a rubber-ring jointing system, allow for additional flexibility, and it can also be used in conjunction with Marley’s OPTIM DWV Sanitary uPVC system for branch connections.
