Hi!
I have a room in the basement that needs to be renovated and turned into a "residential room". The house is an LB house from 1970. Currently, there is a concrete floor and concrete walls. My plan is to lay Platon mat, particleboard, and then underfloor heating on top of this. I have looked at Floore underfloor heating. I then want to lay laminate flooring on top of this. The walls will be framed with steel studs. There are no known moisture problems, but since it is a basement, I want the ventilation that comes with the Platon mat, thinking it and the walls could be ventilated together. I plan to put an OSB board on the studs and gypsum board on top of this. Do I need to put insulation behind the boards?
I would like to hear your opinions on this. Am I thinking completely wrong, and what else do I need to consider to make this work well? I haven't done anything like this before, so I gratefully welcome ALL opinions.

I would avoid Platon completely. Instead, I would use leveling floors to create an air gap between the sole and the surface floor. This can also be supplemented with floor heating, insulation, and ventilation depending on how much it can build up. I would never install floor heating on Platon, as it does not breathe either out or in. And if you don't know the insulation, it's also a waste of energy.

Platoni has insulation boards that you can place on top if you're worried about heating for the crows/worms.
Now I see that you've put the same question in this category, so I'll answer here as well to get a more complete thread:
I'm responding to this because I'm in the same situation and sharing how I think. I'm mainly addressing the floor construction.
The solution people might suggest in this type of situation, where you likely have poor or no insulation under the basement floor, is the so-called reverse moisture migration.
In short, here's what it's about: You heat the concrete slab and the ground beneath it using underfloor heating. In the summer, when you turn off the underfloor heating, the temperature of the slab drops faster than the temperature of the ground underneath. In this situation, when the slab is cooler than the ground, moisture migrates from the ground up towards the slab—reverse moisture migration. This is what people warn about. I haven't personally seen anyone who actually has this problem, but moisture is always bad. One can either insulate under the slab (or under the heated floor) or choose not to turn off the heat in the summer. Insulating is better from an operational economic perspective.
Many suggest doing it properly or putting on socks or getting warm rugs.
I personally have no desire to chip away the entire basement floor, insulate, and re-pour concrete, and I'm thinking along the same lines as you—taking a little shortcut.
My plan is to install Platon and then a reasonably insulating underfloor heating board with heat plates to direct as much heat upwards. I will not use chipboard but an inorganic material (the underfloor heating board) to be safe. In my case, I have radiators in the basement which will provide heating, the underfloor heating is solely for foot comfort. There will probably be a difference in how much heat goes down into the slab if you have a 25-30-degree floor compared to a 20-22 degree floor.
Since this is largely theoretical, no one can say how much heat goes down into the ground and then affects the reverse moisture migration, so I will buy two simple thermometers with sensors on the cord and place one in the slab and the other 20 cm down in the ground below, in this way I can see how much the underfloor heating affects it (once I've seen that, I can just cut off the cables and leave the sensors buried).

You can also lay geotextile between the concrete floor and the Platon mat to prevent the Platon mat from "clattering" against the concrete.

Agree, Nivell even has its own "Platon board": http://www.nivellsystem.se/sv/privatkunder/ventilation/lagbyggande_golv.htmlMatti_75 said:
We have the "regular" Nivell with forced ventilation, a fan that adds about 14-15cm in height. The "new" platon-like variant is clearly interesting since it also has a fan.
We have limited ceiling height in our basement, so "platon Nivell" with LK EPS16 underfloor heating could be an attractive option...
Then we just need to figure out how to incorporate bathroom flooring with tiles and underfloor heating...

Drove with this variant http://www.byggahus.se/forum/golv/208104-golv-i-kallare.html
With parquet, the cheapest oak 4-strip parquet from Byggmax, the floor isn't cold. Not like tiles.
My suggestion is to skip underfloor heating and go with regular radiators and Platon or the solution I did with a warmer floor like parquet.
When you get the first electricity/heating bill, you'll turn off the underfloor heating, I promise you
Otherwise, excavation is required with insulation + underfloor heating.
