Friaphon pipe and fittings are subject to quality monitoring by the Plastic Pipe Quality Association (GKR) in Bonn and are officially accredited by a Certificate/Approval: General Building Inspectorate Approval Z-42.1-220 from the German Institute of Building Technology (DIBt) in Berlin.

Boss branches and pipes are manufactured in accordance with the dimensional requirements of BS EN 1329/BS4514 and are compatible with MUPVC or ABS waste systems to BS 5255 and polypropylene to BS 5254.

The system allows for a simple installation fully complying with the sound protection requirements laid down in standard DIN 4109/VDI 4100.

The sound insulation properties are proven by IBP Test Certificate P-BA 354/1998 from the Fraunhofer Institute for Building Physics.

Friaphon consists of dual formed plastic pipes and moulded fittings in sizes 110mm and 160mm.

The sound-insulating effects of the system result from both its pipes, the production of which is based on the dual forming process, as well as fittings which are connected to each other by way of double couplers and rubber ring joints.

The use of high-quality plastics throughout the Friaphon product range ensures corrosion- and encrustation-free components and parts.

The Friaphon domestic drainage system is intended for use and installation in accordance with BS EN 12056 and the corresponding national standards. It is generally intended for the removal of waste water in accordance with national standards.
