Silenta Premium is a three-layer sewage pipe system made of Silenta PP, which has been specially developed for the pressure-free discharge of domestic wastewater in accordance with the DIN 4109 and DIN 4102 standards. It is ideal for hot, cold and acidic wastewater. Sturdiness of the system is achieved through its impact resistance. The pipe diameters range from 58 mm to 200 mm. The system also includes bases and fittings with additional accessories. 

value-bar-icon-1 Excellent sound insulation

Silenta Premium offers excellent sound insulation. The system thus contributes both to a higher property value and a better quality of life in the building.

value-bar-icon-3 Flame-retardant

The Silenta Premium sewage pipe system has flame-retardant properties and fulfils the requirements of the DIN 4102 standard.

value-bar-icon-2 Acid-resistant

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

value-bar-icon-2 Temperature-resistant

The temperature for installation and operation of Silenta Premium can drop to -20 °C. This is made possible by a thermal expansion coefficient of only 0.04 mm/m*K.

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.

Manifolds / Distributors

GF Piping Systems manifolds and distributors are used to distribute drinking water from one supply line to several drinking water lines. All water-carrying fittings are made of corrosion-resistant materials to withstand high pressures and temperatures in building technology installations.


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.
