New type floor screed

On the fist floor is there a need for insulation between the hollowcore and the floor screed ? Is there an increased risk of cracking if i don't use any insulation ?

If you don't use insulation on the FF then how will you clip the UFH pipes to the floor? I just used 25mm on FF for this very reason.

You also have the concrete bridging to the walls. I would use 50mm under, 25mm border and screed or dry mix.
