Current urban living environments require that more people are living in close proximity to each other.

Councils and town planners are promoting 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 dBlue Sanitary Acoustic Plumbing system which has been specified and installed into buildings throughout New Zealand. The dBlue 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 a 10 year warranty and has been shown to reduce the noise generated by wastewater flowing inside pipework to a level of 20dB.

Additional benefits of the dBlue 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 allows for additional flexibility and can also be used in conjunction with Marley’s OPTIM DWV Sanitary uPVC system for branch connections.
