No insulation material is truly fireproof — what matters is reaction-to-fire classification and the assembly's overall behaviour. Cork sits in the assembly as a thermal layer; mineral barriers handle the fire-rated separation.
A typical strategy combines a cork thermal core with a mineral-board outer skin, achieving both the U-value and the fire compartmentation required by modern building codes.
