ᐅ 36.5 cm Aerated Concrete & Sand-Lime Brick Cladding? Ventilated Cavity or Adhesive Fixing?

Hello dear forum,

For aesthetic reasons, we are considering cladding the ground floor of our urban villa with brick slips. Should these be directly glued onto the masonry? The better option to me seems to be creating a ventilated facade. That means: aerated concrete, battens, and calcium silicate brick slips in NF format. Or does this not work?

No idea, but pay attention to the junction with the plaster. I only know houses where that area ends up with a nasty dirt and mold buildup.

Why?

Adhering directly to masonry (with a properly prepared substrate) is quite standard.

Ok, if that is the usual approach. A friend told me he would simply enlarge the foundation slab slightly and then build a ventilated brick wall. This is much more solid, provides better thermal insulation, improves soundproofing, and is easy to implement.

Then you could also consider building the house directly with a cavity wall system (for example, using sand-lime bricks). The lower part would be finished traditionally with “real” brick, and the upper part with external thermal insulation composite systems (ETICS).
For example, like this:

36.5 cm (14.4 inches) wall + ventilation cavity + brick wall = half a meter (about 20 inches) just for the appearance? That wastes a lot of land and generates many unnecessary costs.

That’s better. However, you only want to clad parts of the house. That means the rest will be plastered. Now your brick facade has become much, much thicker. How do you plan to handle the transition?
