Fire-rating power cables

Insurance companies sometimes require public buildings to have power cables fireproofed. This involves the application of a fire-rated coating directly onto the power cables.

Ablative Cable coatings

Ablative cable coatings are sprayed on the surface of cables to ensure they can keep functioning for a specified period of time during a fire, especially if their supply is of vital importance.

The coating has a mild insulation effect that dramatically reduces the speed of the flame across the surface.


Cafco is a lightweight coating that provides very efficient fire resistance with minimal thickness to structural steel, concrete frames, metal floor and roof decks that can be troweled or sprayed on. It is manufactured in Australia and is the preferred vermiculite spray product used by passive fire applicators all around the world.
