ᐅ Height difference / Level between tile and wood flooring

Hello,
the parquet flooring was installed in our house at the end of last week.
It was planned for the screed to be lower than in the adjacent rooms (kitchen and hallway).
We do NOT have any "extra-thin" parquet, which apparently exists for cases without a lowered screed.

Nevertheless, the parquet is now about 1.2 cm (0.5 inches) lower than the adjacent floor level. Our site manager and the flooring installer say this is "normal" and therefore not a defect. They claim there are no specific guidelines or standard measurements.
We find this very disturbing because such a large difference cannot simply be adjusted by "overlaying" the floor.

Online, I only found one reference in regulations for public areas regarding this issue.
They consider a difference from 4 mm (0.16 inches) upwards as a tripping hazard.

Could anyone tell me if it is possible to apply these kinds of standards or recommendations to private homes in any way?

Raising the floor level is unfortunately not an option because it would significantly affect the function of the underfloor heating.

Best regards,
Hilaria

Hilaria, that’s what I meant. At first, I wasn’t sure if you might have said in person something like “please leave that area with less screed.” As it looks now, the situation is clear. And if the floor coverings are planned right from the start, the surface should also be level, especially with “standard” tiles and parquet flooring.

Yes, Perlenmann, that’s basically how I see it too. Perhaps strip parquet—meaning arranged lengthwise—would work.

Thank you very much.
Perhaps I wasn’t clear enough at the beginning.
We (the clients) have been considering the situation back and forth, and maybe this is an explanation:

The tiles we originally selected were still not available even after 4 months. The initial delivery time was 3 weeks. So, just before installation, we were called in for a new selection, where we had to reluctantly choose different tiles (in-stock items).

Do all tiles have the same thickness? Or could several factors add up to cause this difference?

Who can reliably provide a solution on how to fix this? The flooring installer simply says: “it’s not possible.”

Please consider the tips that have already been given. Submit a formal defect notice with a deadline to your contract partner. It’s probably not the floor installer, so you can disregard their statement. To my knowledge, there aren’t such large differences in tiles. Polygonal paving was probably not planned anyway 🙂

@Meecrob, I do the same. Today, a defect notice will be sent out, including a deadline. Let’s see if they suddenly recognize the DIN standard, which supposedly doesn’t exist for these matters.

@Hilaria, how did it turn out?

(I know this thread is old.)

In the millimeter range, nothing is definitely done on-site—especially not with the screed.

We also have parquet and tiles on the same level, with the parquet being 15mm (0.6 inches) thick plus adhesive and the tiles 10mm (0.4 inches) plus adhesive. For this, rails are installed over them.
