Building physics: different stones?

Hello,

is there any reason not to build non-load-bearing interior walls with BIMS construction panels in a room that is built with T7 Poroton?
Thank you!

From my point of view, nothing - but why [Bims-] instead of gypsum board here?

Hi, well I actually wanted the interior walls to be solid as well. so then there are 11.5 cm Thanks!

Both are solid (???)

11.5 cm of which stone now?

Gypsum wallboard panels are even available in 10 mm thickness.
