Rockwool is spun molten rock - not to be mistaken for fibreglass insulation.

In simple terms, rockwool doesnt burn, its the accelerants added to it that burn (same as any retardant packing).

We put it in very hot two stroke mx bikes. No issues.

We change it very frequently to keep performance up. Weight is reduced quite significantly too due to the build up of oil in old packing. Also, if you pressure wash your bikes you will find the packing becomes water logged which in turn can cause rust probs.

Fibreglass can melt and ignite with accelerants added.
