The Leonardo system at high efficiency



Energy saving and top performances

The versatile Leonardo ceiling system can be used for a wide range of applications. The system is composed of modular plasterboard and graphite panels with pre-inserted, zigzagging MidiX Plus tubing at 3,5 cm spacing. The zigzag design maximises the heat-exchange surface between the tubing and plasterboard.

The plasterboard and graphite panel is supplied bonded to an insulating sheet of expanded polystyrene sintered with graphite in the 3,5 cm spacing version.

10x1.3 mm MidiX Plus tubing
In contrast to the 8x1.1 mm tubing used in traditional radiant ceiling systems, the tubing used in the new Leonardo system has a diameter of 10x1.3 mm. With a diameter increase of 25%, the Leonardo system performs significantly better.
Maximum connection tightness over time
