ᐅ How to Insulate a Partition Wall Between Garage and Living Area?

We have an uninsulated wall between the kitchen and the interior side of the attached garage. This garage interior wall (facing the kitchen) should be insulated because it is built with very low-quality bricks (24cm (10 inches) wall, rather unfavorable pumice concrete hollow blocks). Additionally, this insulation is intended to prevent mold in the kitchen, especially after installing a new window. The roof extends over this area and is continuously insulated.

Since the unheated, uninsulated garage always has fairly high humidity levels (it is designed so that rainwater that reaches the garage door can drain out under the rear garage door via the sloped floor), I see some challenges here. Which insulation material is suitable, and what else should be considered?

So what is it: either pumice concrete or low-quality. By the way, you are asking about many small details—see also https://www.hausbau-forum.de/threads/neues-fenster-in-kueche-schimmelgefahr-ungedaemmte-wand.43380/—it’s better to describe and outline the entire project. This is especially important if you are concerned about mold: the biggest source of mold in energy retrofit projects is uncoordinated individual measures (followed by measures that are basically holistic in concept but executed sequentially in a poorly planned order). It’s best to first clarify the condition of your existing building, for your own understanding and then for the benefit of the community’s overview.
