FANRYN Rock wool board is made from natural rocks such as basalt and limestone,
The rocks are melted in a cupola at temperature of >1450 °C, and the molten lava is
fiberized by a spinner. The inorganic fibers are bonded together using a thermosetting
resin to form the final product which is cut into suitable sizes for easy handling and
installation.
