ᐅ Thermal Break at the Main Entrance

Hello everyone,

I am currently working on how to implement the thermal separation between our entrance area and the paving.
The current situation is that the 160mm (6 inch) perimeter insulation comes up from the basement and currently ends 19cm (7.5 inches) below ground level.
The door including the glass elements extends 1cm (0.4 inch) above the sealing level.
I hope you can get an idea of what I mean...

Now I am still thinking about the best way to create an effective thermal break in this area.
Attached is an idea of how I imagine it.

In other words, to add a 6cm (2.4 inch) layer to the perimeter insulation and vertically bond a 2cm (0.8 inch) Styrodur (extruded polystyrene) board against the floor build-up, then taper it up to ground level at a 1cm (0.4 inch) slope?
This would mean that the first row of bricks would need to be cut at an angle to maximize the thickness of the Styrodur.

What do you think about this approach?

I look forward to your feedback. I hope my pictures help you understand.

hm...
so you wouldn’t use any thermal insulation at all?
Later, I will talk to the guys who will be doing the paving to see what they say. Meanwhile, I’m considering using a 3cm (1 inch) polystyrene board and tapering it from 1cm to 3cm (about 0.4 to 1 inch) over the height of 8cm (3 inches) (paving stone), so that only the first row of stones needs to be beveled. It might work better the thicker the polystyrene is.

I consider it to be a Sisyphean task.
In front of my floor-to-ceiling windows, I have 15cm (6 inches) high quartzite blocks. They are placed directly under the window onto this leveling profile. In total, they measure 11 meters (36 feet), and I don’t see any problem with that. The floor temperature right at the edge is slightly lower than near the walls, but adding 3 cm (1¼ inches) of insulation doesn’t improve that either.
