EPS is a filler material for concrete structures and floating installations that easily catch fire and has mediocre thermal properties. Is it even allowed to use EPS on your walls?

PIR is the typical economical material used for that kind of application. And 12cm is about the minimal thickness you'd want for decent insulation.

EPS will be plastered afterwards. I don’t see any problem having it between brick wall and plastered layer.

12 cm is ok for an old house. More is not economically viable.

I got used PIR panels for cheap for my renovation. There's companies who operate large barns filled with that stuff selling it online.

EPS is not allowed for new builds here in NL, it doesnt meet fire safety codes. To me, that means Im not using it for renovation either. PIR can be had for good prices and is superior in every metric.
