ᐅ Floor construction with underfloor heating and exposed timber ceiling regarding sound insulation

Hello everyone,

For our new build, we are planning a two-story structure with an exposed wooden ceiling (rafter spacing 60cm (24 inches)). The currently planned floor construction is:

- Exposed formwork
- 15mm (0.6 inch) OSB boards
- Roth edge insulation strip 160 x 10mm (6.3 x 0.4 inches)
- Floor insulation panel EPS 040 DEO dm, 50mm (2 inches)
- Roth composite roll 30-2 PS-TK 5.0
- Roth system pipe PERTEX Ø17mm (0.7 inch) installed with a stapler system
- Heated screed (cement screed) totaling 65mm (2.6 inches)
- Partly tiles and partly laminate with RENOVO Aqua stop 1.6mm (0.06 inch) for underfloor heating

My question is:
Is this construction sufficient for adequate sound insulation?
Should more mass be used here (e.g., concrete slabs or a thicker screed)?
Any other opinions regarding this setup?

We want to avoid hearing all noises or footsteps from upstairs very loudly downstairs.

Thank you in advance for any helpful advice.
