Marley Acoustic Soil Friaphon System - Sound Attenuated Drainage System

Friaphon is a purpose-designed sound attenuated drainage system that offers excellent sound insulation, making it an ideal solution for use in care homes, apartments and hospitals.

This dual layer PVC-U system is designed to cater for above ground soil and waste needs as well as internal rainwater service applications.

Friaphon pipe is manufactured by dual-forming two materials of different density. This Friaphon Dual Technology, with a mineral reinforced outer PVC layer, guarantees the excellent sound insulation and airborne sound reduction properties of the system by partially reflecting sound along the boundary layers to absorb it using the pipe’s mass.

The easy push-fit jointing method means straightforward and efficient installation with less material requirements. This provides a significant installed-cost benefit compared with a cast-iron alternative. 

Features and benefits:

• Easy push-fit assembly.
• High impact resistance.
• Resistant to temperatures of up to 95°C.
• Suitable for installation in accordance with BS EN 12056.
• Produced in accordance with the British standard for wastewater drainage, with a Euroclass B-s1,d0 fire reaction rating, the Friaphon system can be installed with the confidence of high performance.
• Friaphon pipe has been sound tested at the Fraunhofer Institute for Building Physics.
• Pipe sizes 110 or 160 mm.
• Friaphon double couplers allow the pipes to be connected to each other free of any structure-borne noises by way of a floating bearing of the pipe ends. At the same time, an integral expansion compensator allows for thermal movement.
• Friaphon rubber-lined support clips are specially engineered for Friaphon pipes. Helping to reduce sound created by vibration, these clips are easy to install using a simple bolt screw fixing method. Supplied with an integrated support ring and wall fixing.
