Laminate and underfloor heating -> Height compensation

Hello everyone,

We are currently in the final phase of our construction project.
The screed is in place and the tiler is ready to start; at the same time, we are looking for suitable laminate. We have already selected a laminate and now I will get to the point.

We have underfloor heating throughout the house operated by an air-to-water heat pump (Luft-Wasser-Wärmepumpe).
The problem we currently have is that in the upper floor hallway area we have planned tiles with a tile height of 9.5mm plus tile structure (we estimate that in the end we will be about 15mm in height above the screed).
The laminate that should border the tiles in three places has a height of 8mm and underneath the impact sound insulation is 2.2mm, so we would have a height of 10.2mm above the screed, i.e. a height difference of about 5mm.
Now the question is how best to compensate for this height difference. I have read something about OSB (chipboard), but it seems to be available only from 10mm thickness, which would unfortunately be too thick.
Furthermore, we have concerns that we might then have problems with the heat transfer resistance?
We would very much like to avoid these "compensation profiles" because we find them very unsightly and impractical.

Thank you very much in advance for your help.

Best regards, benkler1401

Hello everyone,

We are currently in the final phase of our construction project.
The screed is laid and the tiler is ready to start; at the same time, we are looking for suitable laminate. We have already set our sights on one laminate and now I’ll get to the point.

We have underfloor heating throughout the house operated by an air-to-water heat pump.
The problem we currently have on the upper floor is that in the corridor area we have planned tiles with a tile height of 9.5mm plus tile buildup (we estimate that in the end we will be about 15mm above the screed).
The laminate that is to border the tiles in three places has a height of 8mm and underneath the impact sound insulation of 2.2mm, thus we would have a height of 10.2mm above the screed, i.e. a height difference of about 5mm.
Now the question is how best to compensate for this height difference. I have read something about OSB (chipboard), but it seems to be available only from 10mm thickness, which unfortunately would be too high.
Furthermore, we are concerned that we might then have problems with the thermal resistance to heat transfer?
We would very much like to avoid these "compensating profiles" as we find them very unsightly and impractical.

Many thanks in advance for your help.

Google "Wineo damping mat Sound protect eco Profi sd"

It has 3mm - you have already gained 0.8mm... Otherwise, possibly thicker laminate? For example, we took Joka Eastside 9137... has exactly 1cm thickness

Unfortunately, I currently cannot find a way to edit the post.

Furthermore, the question is whether a vapor barrier is really necessary.

Vapor barrier & OSB boards would be quite expensive for 121 sqm ....

Thank you very much in advance for your tip.
The impact sound insulation is already included with the laminate we are interested in, but without a vapor barrier....

5 mm laminate underlay made of XPS/Styrodur from the hardware store.

Not the best idea with underfloor heating..

Hmm... I can consider myself lucky. My construction company clarified the problems beforehand. The screed was leveled in the transition area.
