Dear Sir or Madam, dear forum members, I started building our house about 4-5 months ago (almost turnkey, solid construction 42.5 cm exterior walls, type city villa). Our own contributions include, among other things, the insulation of the roof. Here, to meet all energy saving ordinance requirements, 2 x 10 cm of styrofoam is to be installed and then a protective screed (3-4 cm) applied. Now I have read several times that no vapor barrier needs to be installed on a concrete filigree ceiling. What is your knowledge on this? Thank you very much for your attention.
