ᐅ Raise the planned click vinyl floor or increase the screed level?

Hello everyone,
during today’s site inspection, it was noticed that the screed is surprisingly low. There is about 1.5cm (0.6 inches) of space between the screed and the door frames. The same applies at the transition from the screed to the metal edge of the stairs (where the staircase begins and the floor level normally forms the first step).

The tile and vinyl installer recommended an 8mm (0.3 inches) underlay for the 5mm (0.2 inches) click vinyl. This would make the total floor construction 13mm (0.5 inches), which he considers ideal. We immediately dismissed the original plan to have him glue down 2.5mm (0.1 inches) vinyl.

Originally, I wanted to use a 1mm (0.04 inches) underlay beneath the 5mm (0.2 inches) planks on the other floors. Now I’m concerned that a thicker underlay might negatively affect the stability of the click connections.

Another option would be to raise this issue with the developer and request height adjustment using self-leveling compound.
A third option: use 1mm (0.04 inches) underlay, 5mm (0.2 inches) vinyl, and adjust the frames with silicone. However, this would create unsightly gaps between the door leaf and the floor covering.

The plan is to install Gerflor Insight Clic 55 vinyl as a floating floor, using Gerflor Acoustic underlay underneath.

The area involved is 50m² (538 square feet) of continuous surface.

Which options do you think are reasonable and feasible?

Best regards,
Ricardo

What is the current screed thickness, and what thickness was specified?

Hello Alex,
we were unable to determine the exact height today, as we did not have the appropriate tools at hand.
However, there were three plastic spacers wedged under the living room door frame, each about 4-5 millimeters (0.16-0.2 inches) thick.

The builder was instructed to use -5 millimeters (-0.2 inches).

I would definitely not choose click vinyl. Glue-down flooring is preferable, especially if you have underfloor heating. It’s better to level the screed height.

I will still glue the vinyl, but I believe it is always an exaggeration to say that it doesn’t work with underfloor heating. I don’t think you notice it at all in everyday use.

On top of the screed, there will be an additional leveling compound layer of 1 to 2.5 mm (0.04 to 0.1 inches). Then the vinyl flooring, approximately 2.5 mm (0.1 inches) thick. Where does that leave you?

It’s also unwise to install the door frames before the screed. Why is he doing that? Karsten
