ᐅ Installing vinyl flooring as a floating floor over a floating cork underlayment?

Hello everyone,

First of all: there is no underfloor heating.

We have chosen a vinyl floor that will be installed as a floating floor. Currently, the rooms in question have floating cork flooring. In terms of overall height, it would be ideal to lay the vinyl on top of the cork, so the floor level matches the tiled hallway floors.

The vinyl supplier advised against installing one floating floor over another. Their reasoning: the two floors might move against each other. However, since both materials actually slide over each other, I’m thinking: even if that happens, so what?

I’m actually considering slightly roughening the cork surface because the two floors really do slide well against each other.

So, two questions:
1) Is floating on floating acceptable?
2) If yes to 1), should the cork be roughened beforehand or not?

Does anyone have experience with this and can share some advice? Or could an expert like [USER=28384]@KlaRa provide some brief feedback?

Best regards

Ok. That means the old cork will be removed.
