ᐅ Which Type of Flooring Is Suitable for Underfloor Heating?

Hello,

I need help choosing the right flooring.

We are looking for the right flooring for our new build, for the upper floor and attic.

We will have underfloor heating installed throughout the ground floor, upper floor, and attic.

On the ground floor, we will have tiles laid everywhere.

What flooring would you recommend for the upper floor and attic?
We definitely want to install the flooring ourselves (to save costs).
Our budget is around 35€/m² (approximately $37/m²).

I have researched but got overwhelmed by the wide range of flooring types available.

Laminate and vinyl are the classic options for affordable flooring.

Hardwood flooring is probably too expensive for us; we won’t manage with a maximum of 35€/m².

What are bio-based floors, luxury vinyl tiles/planks (LVT), or cork flooring?

Which wear rating should we choose if the floor needs to be as durable as possible?
Should you always go for the highest wear rating?

We also have a dog (in case that’s relevant for the selection).

I hope you can help me.

Well great, now the direction is right. It only took 11 pages and 65 posts... 😉 Now we just have to convince you that gluing is really better than floating installation.
I wouldn’t compete with that. Both have advantages and disadvantages. Floating floors feel nicer to walk on, softer. I have floating parquet, a friend of mine has glued. You can feel the difference when walking.
And it’s easier to do it yourself.

@AxelH. I had the impression that most people tried to discourage me from choosing vinyl because it is made entirely of plastic.

We are primarily looking for a floor that suits our needs in terms of properties. What material it is made of is initially secondary for us.

Yes, gluing it down is a tricky issue; we definitely need to install the floor ourselves, whether it’s a floating floor or glued down.

I’m not confident about gluing it down myself, and if something goes wrong, it’s harder to fix later because everything is permanently glued.

Self-adhesive vinyl is probably not great either (likely doesn’t stick firmly).

@motorradsilke Thanks for sharing your experience. We are also leaning more towards floating installation.

What type of vinyl would you recommend? There is regular click vinyl where you need to install the underlayment separately, and rigid vinyl where the sound insulation is already integrated.

Which one is better?

The first question should be: Is my substrate suitable? Depending on the choice of floor covering, the screed alone may not be sufficient. Just google "vinyl substrate requirements"—there is a lot of information available, including regarding any necessary measures for leveling the floor when doing a DIY installation.

Okay, I will take a look. I thought vinyl flooring could simply be laid directly over the floating screed.

The issue with floating installation is that you have an additional air layer in between. This does not matter with radiators and may even be desirable, but it is less ideal for underfloor heating. Material expansion is also more of a problem with floating installation because everything can shift. Large south-facing windows are rather disadvantageous in this context.

In the upper floor and attic, we do not have any large windows facing south.

On the upper floor, there are only two standard windows facing southwest, and in the attic, only the skylight faces northeast, along with two floor-to-ceiling windows facing north.

We do not have any issues with excessive heat from solar radiation.
