ᐅ Vinyl Flooring: Should It Only Be Glued When Used Over Underfloor Heating?

For us, the material costs were basically the same. However, in my opinion, the gluing cannot just be done by yourself, so you have to pay for the labor. On the other hand, the click system flooring can be installed quite easily as a DIY project.

Labor costs were about 22 euros per m² (approximately 2.05 USD per ft²), including baseboards.

If you have it installed, there was not much difference for us.
The glued vinyl was 5€ per square meter (approx. 5.5 USD per square yard) cheaper than the click-lock version.
We paid 10€ net per square meter (approx. 11 USD per square yard) for installation (same for both options), but for the glued vinyl, we also paid 5€ per square meter (approx. 5.5 USD per square yard) for the additional floor structure (height adjustment due to tiles).

We found glued vinyl to be more affordable. The material was 20 euros more expensive, but installation was 25 euros cheaper. However, there were a few additional euros for the screed heightening.

We are currently in the process of selecting designer or bio-based flooring. The question often comes up about which installation method is better: glueing or clicking.

The new floors, for example from Wineo, have a thickness of 9mm (3/8 inch) and include integrated sound insulation.

I find it hard to understand how a glued layer that is only 1mm (0.04 inch) thick could be of higher quality than a 9mm (3/8 inch) floor with the appropriate HDF core layer, and so on.

Could someone help me with this? By the way, we do not have underfloor heating!

What exactly are bio floors?
The total thickness of the vinyl floors we compared—whether glued or click-lock—was consistently between 5-6mm (0.2-0.24 inches).

The only relevant factor is the thickness of the wear layer. The rest consists of the substrate layer with the click system and insulation. You don’t need either of these with the glued option.
