MAGNUM FiberBoard

System plates

Fibre plasterboards are used as a carrier for pipes in dry floor heating systems. Due to the properties of the fibre plaster, the panels allow heat to spread effectively over the heating space. When using fibre plasterboards, the installation of heat transfer plates is not necessary. The panels are 18 mm thick and are only suitable for a Ø12 mm underfloor heating pipe. The fixed pipe spacing is 12 cm.
