ᐅ Hollow bricks and mineral insulation—are they a poor combination?

Hello everyone!
Today we had a construction consultation with a friendly small company from the surrounding area that works exclusively with monolithic wall construction. From my point of view, this is commendable, but unfortunately, their services are not affordable for us.
We would have preferred at least a mineral-based external insulation and *no* ETICS (external thermal insulation composite system). During the discussion, it was mentioned that mineral-based external insulation tends to clump, lose its insulating properties, and potentially become damp—and therefore completely unusable—especially when combined with a brick facade, which is already rather expensive for us.
However, I have noticed quite frequently in the neighborhood on renovations and new constructions that mineral insulation blocks are used on the exterior. These buildings, which have sometimes been under construction for a longer period (I have passed by often), have repeatedly been completely soaked by rain during that time. But shortly after the rain, the insulation neither appeared clumped nor otherwise damaged.
What do you think about mineral-based external insulation as a cost-effective compromise between monolithic construction and ETICS? Which materials or possibly specific products are recommended based on experience, particularly for being robust and durable?
Everything is with perforated bricks…
Thanks in advance!
Best regards,
Christian

Hello,
Using XPS for screed insulation would actually be a bad idea... while it has excellent compressive strength, this also means it transmits sound very well.

In the base area, XPS is usually used because of its compressive strength, yes. Also for insulation under floor slabs, under underfloor heating (although there EPS is often used as well).
