Good evening everyone,
we plan to install vinyl flooring instead of tiles in the bedrooms. This results in a height difference of about 8mm (0.3 inches) between the rooms with tiles (13mm (0.5 inches)) and the vinyl flooring (4.8mm (0.2 inches)).
Since we want to avoid using transition strips and prefer to even out the floor construction, we are now considering how to achieve the 8mm (0.3 inches) height increase. All rooms have underfloor heating installed. The screed is already in place, and we did not want to raise the floor level in order to keep options open for future flooring changes.

As a first option, cork comes to mind, as it can bridge the 8mm (0.3 inches) difference. In terms of thermal resistance, a value below 0.15 m²K/W can just about be achieved.
Another possibility would be protective mats used in construction that can also raise the floor height. Are these suitable for underfloor heating? In terms of thermal resistance, they are even better than cork and also cheaper. Would you recommend them for raising the floor? Are there any other alternatives to increase the floor height when underfloor heating is present? Thank you in advance.

Maybe you could first describe exactly which vinyl flooring you want to install. Sheet vinyl, planks, self-adhesive, backing material.
This will determine which subfloor you can work with in connection to the underfloor heating.

Off the top of my head, MDF boards with a thickness of 8mm (0.3 inches) come to mind.

Nowadays, there are great transition strips with height adjustment. They are hardly noticeable at all.

Use cork or simply thicker vinyl flooring.

Hello,
first of all, thanks for the quick reply. The planks are intended to be installed floating with a click-lock system.
The MDF boards would also be an option but are still more expensive than cork flooring...

Any opinions on protective building mats? It would of course be somewhat unconventional, but is it basically possible with underfloor heating? 🙂

Use thicker impact sound insulation. Parador offers it in three different thicknesses. However, I am not sure if it is compatible with the requirements of underfloor heating.

This should be coordinated with the screed contractor, who can adjust the screed height for each room.
