Note that creepage is not an insulator. Creepage is nothing more than a boundary surface. One characteristic of a boundary or junction is that the two insulating media likely have radically different electric strength ratings (volts per unit distance through the medium).

Creepage is always/generally larger than clearance unless special measures are taken. This might include putting a notch in a PCB so that the creepage distance is extended by twice the depth of the notch. The clearance (measurement of distance in air) will be unaffected but the creepage (distance along the surface) is increased.
