ᐅ Insulating a 38 cm Brick Older Building with Aerated Concrete / Autoclaved Aerated Concrete (AAC)

Hello,

As mentioned at the beginning of my question, I am considering buying a house. According to an unclear floor plan, a 34cm (13 inch) brick wall was used (does such a size even exist? Maybe it is 38cm (15 inches)). In the future, I would like to insulate the house and I am researching the available options in advance. For several reasons, I am against using polystyrene insulation!
Now I am looking for a good alternative!
I came across aerated concrete / autoclaved aerated concrete (AAC) / aircrete / mineral foam / Ytong / and other similar materials.
Is it possible to place these blocks as insulation in front of or on top of the bricks?
Does anyone have experience with this? Any issues with moisture or mold?

Many thanks and best regards!

Every option has its pros and cons. I wouldn’t dismiss this option outright. The image of it as a "flammable plastic casing that turns into hazardous waste" is not necessarily accurate, and it should be weighed against the disadvantages of other retrofit insulation methods. The supposed breathability through multiple layers of purely mineral building materials is a point that can definitely be debated.
