Rockwool fibres are inorganic and composed mainly of silica and alumina, Rockwool is manufactured from various types of rock of predetermined chemical compositions which is melted at super high temperature in a technically advanced Cupola, The resulting molten alumino-silicate is drum spun at very high speed to produce “ROCK FIBRES”
    that are bonded together with a thermosetting resin and Additives.

    The fibres are also sprayed with binder’s to make fibres retain its shape and prevent shrinkage during storage. The fibres are also impregnated with special additives to keep it water repellent.
