Passively ventilated floor with Delta Yellow Line

[Nene]

I'm trying to understand the assembly instructions for this product. It's about a Platon mat that only adds 4 mm. It should be used when you want to lay wooden floors on concrete where there is a risk of moisture.

According to the assembly instructions, you should prime and moisture-proof with tape at the floor-wall angle. Then, you're supposed to place a Platon angle there to ensure ventilation. Now to my question: why prime and moisture-proof in the floor-wall angle when you are directing moisture away with the Platon angle? This seems like a completely unnecessary step and moreover, it counteracts healthy moisture transport from the concrete floor. Does anyone have experience with this system?

According to the seller at Delta:
Priming and moisture sealing is only done if the concrete floor is on sills, to avoid cold drafts, that is. If it's a slab on grade, you skip this step. However, you must always have the upturned edge.

I am still grateful to hear about experiences with this type of passively ventilated floor.

Reviving the topic about 11 years later. Does anyone know the difference between Delta yellow line and platon?

Different brands but the same function. It's pretty much the same which one you choose. Our Yellow line has done its job completely to our satisfaction.

Thanks for the reply!
Do you have mechanical ventilation?

No, no fan, just passive circulation.

We want to put it in the basement, on an uninsulated concrete slab. The total floor area is around 90 sqm distributed across different rooms. Of course, it's best with mechanically ventilated, but how do you really know if you can manage with a passive (non-mechanical) one? I find this very difficult...
