Silenta Extreme is a new PP-based halogen-free, resistant to fire (B-s1, d0) and noise-insulated [18 dB(A)] soil, wastewater and drainage piping system, especially developed and being produced to the highest technological standards for you to increase your building safety and comfort with its improved features and structure. Due to its halogen-free feature, it does not emit any poisonous and lethal gases in case of fire.

It is manufactured with the latest generation of multilayer (three different layers) polypropylene technology according to the requirements of EN 1451, EN 13501 and EN 14366 standards. The pipe diameters range from 50 mm to 200 mm. The system also includes bases and fittings with additional accessories.

value-bar-icon-1 Excellent sound insulation

Silenta Extreme offers excellent sound insulation. The system thus contributes to both a higher property value and a better quality of life in the building. This system is approved in accordance with EN14366 and DIN4109.

value-bar-icon-1 Flame-retardant

The Silenta Extreme sewage pipe system has flame-retardant properties and fulfills the requirements of the EN 13501 standards. According to EN 13501 norms, the fire performance is B; hardly combustible, s1; very weak smoke emission and d0; no dripping during a fire.

value-bar-icon-1 Halogen-free

Silenta Extreme is a PP-based halogen-free solution therefore there will no occurrence of any deadly toxic gases during a fire.

value-bar-icon-1 Acid-resistant

With a pH resistance of 2 to 12, Silenta Extreme resists both organic and inorganic acids, making it an excellent alternative to cast iron systems.

Multilayer Pipes

Multilayer composite pipes combine the advantages of plastic and metal. Thanks to the flexibility of plastic and the strength of metal, the pipes are ideally suited to withstand the wide range of temperatures and pressures found in both cold and hot water systems.

Bends & Elbows

Bends and elbows are essential fittings that easily change the direction of pipes. The extensive range available offers not only multiple materials but also different curvature degrees to easily fit your piping system.

Caps & End Caps

Caps provide a tight seal and stop the flow direction of a piping system. GF Piping System caps are available in different dimensions, different plastic materials and malleable iron to fit all of your needs. Temporary caps ease the pressure testing of an installed pipeline.

Couplers & Sockets

Simplify the pipe installation process with couplers and sockets. Specially designed to slide easily over pipes with no extra equipment required, they are cemented, welded or mechanically connected to create a pressure-tight joint.


Reducers are used for effecting a smooth transition between two pipes or fittings with different dimensions. The wide selection available covers an exceptionally diverse area of applications. They are available in short or long versions and in centric or excentric versions.

Tees, Y-Pieces and Crosses

When creating branch lines, lightweight tee, wye, and cross fittings make installation much easier. These fittings are made from a range of materials and malleable iron and cover multiple dimension possibilities including various reductions on the same fitting.
