Vinyl deforming under strong sunlight exposure?

Okay, so vinyl is- well, what actually? :D

That is simply and straightforward PVC. Since the name "PVC" was commercially burned, it was renamed. And the term "design flooring" was added. At the same time, you can charge more for it... Raiders is now called Twix- otherwise nothing changed! ;) PS: When OVC burns, hydrogen chloride, dioxins, and also aromatics are produced. That means: definitely do not inhale the resulting gases, a complete renovation of the apartment will be necessary anyway!

Depending on the type of vinyl flooring, it warps even without exposure to sunlight. This is currently happening at a good friend's place right in the living room. It looks like cheap laminate that slightly lifts at the edges. The money for good parquet is definitely a worthwhile investment.

How could this happen? Not by sunlight. What else is there?

Heat, humidity. In the case of floating installation, an insufficiently executed perimeter joint.

But that was then a transfer as a self-experiment, right?

No, specialist company, but over 5 years ago. Still a ridiculous lifespan for a floor. It also feels like walking on plastic... no comparison to parquet.
