VarioModul-pipe 11,6x1,5 Laser

Aluminium Multi-Layer Composite Pipe

The Variomodular pipe 11.6x1.5 Laser is an aluminium multi-layer composite pipe. Five layers are joined together and make the pipe flexible, easy to bend and dimensionally stable.

The innermost layer is made of polyethylene and temperature resistant. The inner surface is smooth as glass, making it impossible for deposits to form. The water flows through the pipe without resistance and with minimal pressure losses.

Construction VarioModule-pipe 11,6x1,5 Laser

Das Alu-Mehrschicht-Verbundrohr ist bereits in der Rückseite der ModulWand fertig integriert.

1 Raised-temperature-resistance polyethylene (PE-RT)

3 Homogeneous laser-welded solid aluminium pipe
4 Adhesive layer
5 Raised-temperature-resistance polyethylene (PE-RT)


  • Fully corrosion-free
  • Optimum creep behaviour
  • Just as light as a plastic pipe
  • 10-year guarantee with certificate
  • Flexible, easy to bend, extremely good hydrostatic stability
  • Resistant to hot water additives (inhibitors, antifreeze)
  • Mirror-smooth inner surface – less pressure loss – no encrustation
  • High pressure and temperature resistance (10 bar, +95 °C)
  • 100% oxygen diffusion-tight
  • Lower linear coefficient of expansion, lower heat expansion forces
  • Tested as per EN 21 003 (IMA Dresden), SKZ A 397

Where the VarioModule pipe is deployed

Bei den baubiologisch geprüften Gipsfaserplatten für die Wandheizung und Wandkühlung sind die Alu-Mehrschichtverbundrohre bereits integriert.

The Variomodular pipe 11.6 x 1.5 Laser is already fully integrated in the rear of the ModulePanel. The heating pipe is embedded within the 18 mm thin, health and safety tested gypsum fibre board, with a grid spacing of 75 mm or 105 mm.

The ModulePanels are ready to be installed on walls, pitched roofs and ceilings.


The aluminium layer guarantees elongation up to nine times lower than PEX pipes. That means the VarioProFile pipe is ideal for surface heating and cooling systems.

Creep rupture properties

Gibt die langfristige Warmfestigkeit von Bauteilen an, die langzeitig hohen Temperaturen ausgesetzt sind, zum Beispiel Rohre einer Fußbodenheizung.

The creep behaviour indicates the long-term heat resistance of the VarioProFile pipe. This behaviour has been scrutinised in a creep rupture test. It is very important for heating piping as this is exposed to high temperatures over long periods.

Scrutinised creep behaviour has been tested for a service life of 50 years.
