Acoustic piping system helps keep new development quiet

Mechanical Services Ltd. “We have used Terrain’s PVC above-ground soil and waste system on a large number of developments in the past and it has always provided excellent performance,” commented RAD’s Mark Radcliffe. “We were naturally keen to see if the Acoustic dB12 system which was launched recently could meet our specifications and perform to the same high standards, which it has. Polypipe Terrain worked with us to overcome some initial technical issues, and once work started we found the Acoustic dB12 system to be both quick and easy to install.” The pipes and fittings in the Terrain Acoustic dB12 range allow the creation of soil and waste piping systems in multi- occupancy buildings such as hotels, apartments, hospitals and schools, where minimal noise transmission is a key requirement. The three-layer construction allows the pipes and fittings to provide acoustic performance that surpasses the requirements of Building Regulations Part E, and to also meet Class B1 fire protection standards. A wide variety of components, pipes and fittings are available, providing flexibility in system design and allowing an acoustically insulated drainage system to be created for virtually any application.

POLYPIPE Terrain’s Acoustic dB12 piping system has been implemented in the new Saxton residential development in Leeds, UK. The dB12 pipes and fittings have been used to create soil and waste systems that provide a high degree of acoustic insulation and prevent noise transmission within the new Urban Splash development. The development involves the complete refurbishment of two tower blocks that

previously provided accommodation for housing authority tenants.

The prevention of noise transmission between the new apartments demanded an acoustically insulated piping system that would provide reliable and effective performance.

Terrain Acoustic dB12 was specified by mechanical engineers RAD

The Saxton residential development is ▼ ▼ the first Urban Splash development to feature Terrain Acoustic dB12
