Which foam underfloor?

[DrKassler]

Hello!

I will soon be casting a new floor in the basement with underfloor heating and will be buying EPS insulation according to standards in the coming days.
But what density should the EPS have?

Best regards,

S80 is sufficient, but it doesn't hurt to go up to S100, I think.

Then I'll head to byggmax this afternoon and add to my personal bankruptcy.
