Are transition profiles absolutely necessary?

Hello,

we have different types of flooring in our new building. One floor has glued parquet, with cork strips inserted as an expansion joint. On the other floor, so-called cork laminate was installed, floating. Actually, we wanted to use cork strips here as well, but we were told that this does not work well and after some time the floor would lift. A transition profile would be unavoidable.

Is that the case or are there any alternatives?

For floating floors, you always need a transition profile. But even here, there are elegant and unobtrusive ones or the DIY store stick to trip over.

Any recommendations? The regular aluminum parts are absolutely ugly

We also have only floating floors on the upper floor and these here: Proline Abschlussprofil PROCOVER Designfloor. They are quite unobtrusive. However, on one side there is always tile, so it’s not a floating to floating transition.
