Low-noise, high-performance drainage

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 is suitable for temperatures of up to 95°C and is highly impact resistant. 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.

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.

Friaphon pipe

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.

Suitable for soil, waste and rainwater services
Sound tested at the Fraunhofer Institute for Building Physics
B s1 d0 Euroclass fire rating
Available in 3 metre lengths
Sizes 110mm and 160mm

Friaphon double couplers

When using Friaphon double couplers as standard connectors, Friaphon pipes can 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.
