Flooring Hydrostar, does anyone know it?

I saw an advertisement for the latest product from the company Haro in a hardware store flyer: does anyone know Hydrostar?

I am considering whether it might be useful to install it in the entrance, utility room, and even bathroom and WC (?).
Regarding the material, I only know that the bottom layer is made of cork, and the rest is PVC and phthalate-free...

Hello Lucrezia.
Surely you have already informed yourself about this type of flooring on the internet. At least that would be expected.
The polyolefin covering (mostly based on PE) with the so-called "AquaReject carrier plate" is probably suitable for all the areas you listed, even in the bathroom, if the flooring is fully glued down.
What will be surprising during the research: there is no published product data sheet for this covering!
Therefore, it is not known for which load class it is rated. It could be that it "weakens" with unpleasant wear, especially in mechanically highly stressed entrance areas. This has always been the major weakness of such types of coverings over the past decades.
But that remains, until disproven, at first (albeit justified) speculation.

Thank you, KlaRa! No, in fact I hardly knew anything about the nature of such floor coverings, as I have only dealt with wooden floors so far. PE sounds OK, as it is low in pollutants (theoretically free..), it is also used for food and baby food packaging. The price is also quite good (about 20€/sqm). Detailed information is still missing, so I will report here when Haro answers my inquiry

Haro reacted quite quickly. Maybe someone here is also interested in the technical data:

Regarding the surface of the floor covering:
Abrasion-resistant, lacquered thermoplastic decorative layer with up to 4-color printing (free of PVC and plasticizers).
Intermediate layer:
AquaReject carrier board (5mm) -
Bottom layer:
Cork, 1 mm

Suitable for commercial and residential areas with heavy use. Stain resistance "durable."

"the patented glue-free connection system ensures an easy, precise, and permanent installation of the design floor.
At the front side: snap button system
At the longitudinal side: locking by angling."

And now the price question: Can it be assumed, especially based on the "AquaReject carrier board," "thermoplastic decorative layer," and connection system, that no problems will arise in the laundry room/bathroom/WC?

Hello "Lucrezia". Yes, that is possible. I have been observing polyolefin coverings since their market introduction about 20 years ago. The problems have always arisen with the backside adhesion (adhesives stick little to nothing on PE). Now the panels based on loose lay are entering the market. This should not be a problem for wet rooms. The question of all questions is how dimensional stability behaves under thermal stress (e.g. underfloor heating) in practice. Due to the carrier board, this will probably remain within an acceptable range. Because polyolefin coverings are standardized as a "modular floor covering" according to DIN EN 16511. According to the manufacturer's classification (class 21 to 34), only class 34 has limit values for dimensional changes caused by moist or dry climate conditions!! For dimensional changes due to heat, all usage classes >23 are at less than or equal to 0.25% (but again only based on delivery dimensions). A wide and sometimes confusing field for the layperson .... Regards and have a pleasant weekend: KlaRa

Thank you, KlaRa, for your very clear answer! Does this mean that in this class there are materials that could deform with temperature changes? (Because they are thermoplastic?). Can manufacturers provide guarantees for this, or is it sufficient if it just says "suitable for underfloor heating"?
