Screed with insulation:
This is the most common floor finish, typically the insulation (Closed Cell) is installed on top of the floor slab with the floor membrane over the top.
Chipboard Floating Floor:
This is typically used in remedial situations where the floor to ceiling height is not sufficient to allow a floor screed. It requires the perimeter channel to be recess into the floor slab, the floor membrane is then laid over the floor slab and then the Tongue & Groove Flooring Chipboard (or similar) is laid directly onto the membrane.
