rock wool sandwich panel can withstand more than 1000°C without melting, whereas the binding agent is lost at temperatures in excess of 250°C. When the temperature rises above 250°C, the binder will evaporate in the zone which is exposed to 250°C or more. But the fibres will remain intact as their inbuilt cohesiveness and layering will keep the fibres together, ensuring that the material will retain its rigidity and protect the material beneath it from being affected by the fire.
