Vinyl Click Floor Tiles - What Underlay?

[hkp57]

I want to fit Click system vinyl floor tiles in my conservatory, I have had mixed advice about what underlay to use.

The floor currently is concrete with ceramic tiles on top, I want to lighten the color and take the cold feel of the tiles away.

It is a conservatory but we use it all year round as a sitting / dining area.

Advice given

1. No insulation underlay as not required.
2. 1mm thick underlay to compensate for minor uneven finish to existing floor
3. 6mm thick foil backed insulation for noise and thermal proprieties


The 6mm sounds like what I want but concerned the point loading from a table leg or a dining chair may split the click joints if its on a weak point due to the softer more compliant 6mm backing..

Something thin and fairly solid, you don't want any flex in these floors. Can't remember the name of the stuff we used, but it was only a couple of mill and was foil backed.

I lay floors for a living . I have only ever laid one vinyl click job in a small kitchen . They are not a clever idea. They should not (in my opinion) go on underlay as even the slightest movement will cause the T&G joint to fail. I have replaced at least 3 jobs in the last 18 months with stick down vinyl tiles . You would be better off laying a latex screed over your tiled floor to blind out the joints a lay a cushion type vinyl .
