The BRANZ-appraised Marley dBlue Acoustic Plumbing System is fast becoming the top choice for contractors and specifiers because of its unique blend of acoustic performance, heat resistance and mechanical strength. Its advanced triple-layer polypropylene construction, reinforced with a state-of-the-art combination of plastic and sound-absorbing mineral filler (PP-MD), maximises absorbance of sound by up to 16 dB(A) and significantly lowers wastewater noise for a quieter living and working environment.

Designed for use in multi-storey buildings such as apartments, hotels, hospitals and offices, Marley dBlue eliminates the need for additional acoustic lagging, streamlining installation and reducing costs on site. Proprietary rubber-lined acoustic brackets further enhance its noise-reducing performance, making it an optimal choice for high-density developments.

Aaron Rink, Hydraulic Services Design Consultant at Waikato-based Flow Consulting, highlights that the rise in vertical and condensed living has made acoustic comfort more important than ever.

“I personally specify Marley dBlue on all our commercial projects due to its acoustic properties, negating the need in most situations for wastepipes to be wrapped in additional acoustic lagging. It takes up less space because you’re not having to allow for the fatter acoustic installation that would otherwise be required”.

Beyond its acoustic benefits, Marley dBlue boasts a high-temperature resistance, making it ideal for commercial kitchens and other industrial applications. The system withstands temperatures up to 90°C (short-term) and 80°C (continuous), outperforming conventional PVC systems.

Rink says the ability to handle higher temperatures gives us “peace of mind where there might be mechanical condensate drain discharges going into the system”.

Another reason Flow Consulting relies on Marley dBlue is because of Marley’s reliable inventory management.

“They’re very committed to the plumbing industry and in supporting all plumbers in New Zealand. They provide very good tech support and backup for those contractors that are installing their products.”

Marley dBlue guarantees the proper functioning of drainage systems by combining upfront training, technical support during construction and inspection afterwards.

Sustainability is also at the heart of the dBlue system. Offcuts can be returned to Marley for recycling, contributing to a circular economy. By using an advanced manufacturing process that optimises energy use, Marley dBlue helps in minimising environmental impact, and therefore reducing the overall carbon footprint for the construction process.

With innovation, performance and sustainability at its core, Marley dBlue continues to be the quiet achiever of New Zealand’s plumbing industry.
