I personally don't like a screed that sits directly on top of the insulation but if i were to advise i would say a minimum thickness of 75mm but would prefer more.

As for screeds laid directly onto an existing slab, i would say minimum thickness of 50mm though it is possible to go thinner if the you incorporate granite chippings-to-dust into the screed mix.
