ᐅ Solid Vinyl vs Vinyl with HDF Core

For floating vinyl flooring, there are both types with a vinyl core layer (solid vinyl) and those with an HDF core layer (vinyl on HDF backing).

Construction:
Wear-resistant polyurethane coating, vinyl wear layer, vinyl decorative layer, stabilization layer, and then either another vinyl layer or HDF.

Vinyl is suitable for wet rooms, expands less, and the product consists of fewer different materials, each with its own properties.

Sometimes the same manufacturer sells both vinyl with an HDF core and solid vinyl with a vinyl core.

Why choose an HDF board at all instead of solid vinyl, which expands less and is more water-resistant? The construction described above (wear layer, etc.) is always the same.

Interesting topic. I also looked at various click vinyl options and thought they were pretty cool. However, I just can’t get over the fact that I would end up with PVC in the house again, which I actually wanted to avoid.
Paying extra just because of the term "design floor" compared to proven laminate seemed a bit pointless to me.

Then I checked out the current laminate floors and have to say that, to ME, once they are installed, I can’t see any visual difference.
And if the floor is professionally and properly installed, nothing should go wrong.

I just feel more comfortable without PVC in the floor. But it’s all a matter of mindset.

And if I don’t like the laminate in a year, well, I’ll just get a new one...

Easy.

Regarding your specification of 20x20m (20x20m), I am not 100% sure according to the manufacturer's guidelines, but I will confirm tomorrow. The statement that the panels do not expand is definitely incorrect. As I said, it is less risky than "normal" vinyl, but I personally would not risk 20 meters (66 feet). You then have one surface that has to withstand different indoor climates. And if stresses occur, the narrow door area is particularly the bottleneck or almost a predetermined breaking point...

Joints in the floor, as usually found at doors, must be incorporated anyway. Our length will not reach 20 meters (66 feet) either, but just over 10 meters (33 feet) on one side.

The underlay on the backside is also good, especially an advantage with underfloor heating, as it is fixedly glued – so no additional air layers are possible (which slow down heat transfer)

Why glue it? As far as I know, planeo Isocore vinyls are only suitable for floating installation, not for gluing.

That is not entirely correct. Joints in the screed only need to be transferred to the floor covering if it is fully glued down, and only if they are actual movement joints. So-called dummy joints (scratched cuts) should be filled with resin. With floating installation, movement joints can be covered because the screed slab can move independently of the floor covering.

However, manufacturers limit this for floating installations at doorways due to differing climatic conditions in adjacent rooms.

Regarding Isocore, the manufacturer allows a continuous surface of up to approximately 250 square meters (2,691 square feet)! Multiple connected rooms may also be installed without separation. Therefore, no joint is needed even at doorways.

That’s correct. Isocore should not be fully glued down! I meant that the underlay itself is fully adhered to the floorboard. This provides a – small – thermal advantage for underfloor heating. When underlays are laid loose, there is always, “in theory,” a minimal air gap between the underlay and the vinyl. And air is well known as the best thermal insulator.
However, this advantage is naturally small. I only mentioned it for the sake of completeness...

Hello Farilo, the price difference is not due to the term "design flooring" but rather the significant advantages compared to laminate (quieter, warmer underfoot, easier to maintain, more resistant, more durable, wider range of applications, etc.).
The ecological aspect is also a factor. Personally, I prefer natural products like real wood parquet. The HDF core of laminate is only about 85% wood, with the rest being binders and additives. But it is certainly more environmentally friendly than vinyl, no doubt about that!
