ᐅ Window sill connection strip thermal bridge?

Hello everyone, I recently had a new front door and windows installed in the entrance area. I received a window sill connection strip, and now I’m wondering, isn’t that a thermal bridge?
I have triple glazing and I believe the window frame is 88mm (3.5 inches) thick, and the narrow strip seems to compromise a lot of the insulation. Outside there is an aluminum window sill, and inside a granite window sill was installed in front of the strip.
I’m just asking out of curiosity, since I can’t make many changes at this point anyway.

If you google it, only Polish websites come up... Is there no German product for this? Or is it only done this way in Poland? I've never heard of it before...

As far as I know, a Polish manufacturer patented Klinaryt. Technologically, it is a very densely compressed EPS. This is what I quickly found online.

There are also Purenit thresholds. They work on the same principle but are somewhat more complicated to handle on site.

Our windows came from Poland, so Klinaryt was installed.

Oops, @11ant – I made a typo in my previous message...
Material data: thermal conductivity 0.035 W/mK, fire rating E, R 2.85 m²K/W, U 0.35 W/m²K.

But 0.35 is not much better than the standard extension profiles, is it? They also contain XPS with 0.30–0.35...

0.35 is neither better than an aerated concrete or porous clay insulation block, nor than the expanding foam that the window sill installer sprays underneath until it starts to smoke.
