ᐅ Click vinyl or glue-down vinyl for underfloor heating and floating screed

Good morning,

our building specification states: "...floating cement screed with impact sound and thermal insulation," and "underfloor heating with hot water."
Which type of vinyl flooring would be advisable here, and what experiences have you had? A discussion yesterday with a specialist retailer suggested glued vinyl, as the joints in click vinyl might be affected due to heat transmission. However, I have also heard opinions in favor of gluing...

Thank you,
haukee

The recommendation is clearly to use adhesive bonding. We did the same with the same flooring and were advised to do so as well.

Could we please return to the original question.

? I already mentioned that we have glued-down vinyl flooring and are happy with it. To be more precise: glued planks without an underlayment.

Bonding is likely better due to the previously mentioned thermal bridging.

Having air between the screed and the floor covering significantly worsens this, which in turn leads to higher supply temperatures for the heating system. This is especially problematic for heat pumps.
I would also recommend checking the manufacturer's specifications for the floor covering. It is very likely that it is not approved for floating installation with underfloor heating.

Glued-down floors also provide a much more comfortable feeling underfoot. Anyone who has experienced a direct comparison knows what I mean.

We have glued multilayer parquet flooring (oiled) as well as glued vinyl planks in the kitchen (both installed over underfloor heating).

I am facing the same question and asked about it on the Planeo site ("Installing vinyl flooring over underfloor heating").

There they told me regarding adhesive installation that there is "no real advantage. Neither in terms of cost, heating efficiency, acoustics, nor technically."
