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?

Partially, only on one side of the house, "adjacent" plaster, originally not planned in the wall construction: this clearly indicates facing bricks – which, simply put, are full clinker bricks cut into thin slices. Just out of curiosity, what did you mean at the beginning by "battens" – and by "calcium silicate brick facing"?

Also, some information from a friend; he solved it like this at his place: 24cm (9.5 inches) aerated concrete, structural timber with mineral wool insulation, vapor-permeable membrane, counter battens, fiber cement boards, and then covered with facing bricks. I have no idea about it. He definitely has extremely good U-values. In summer, the house stays cool; in winter, warm. Hardly any heating costs.

But for us, it’s about the street side…

You are mixing everything up. A 36.5cm (14.4 inches) Ytong block provides sufficient thermal insulation. Applying plaster directly onto it, without polystyrene or similar materials, is enough. Alternatively, you can use brick slips instead of plaster. Nothing more is necessary.

I am aware of that. However, 11ant asked about the original intention, and I only explained the wall construction my friend used for his house. We are satisfied with the 36.5cm (14.4 inches) blocks and also with proper brick slips.

I find my friend's wall construction too complicated.

By the way, calcium silicate brick slips should just be called calcium silicate brick slips.

Oh, sand-lime brick facing should be called sand-lime brick facing.

That’s exactly what made me hesitate: I wouldn’t call sand-lime brick exposed masonry or veneer “brick facing.” To me, that term is only associated with bricks from the clay brick family, and I don’t recall ever encountering sand-lime brick as thin facing bricks. They might exist, but they are definitely much less common on the market. I also can’t imagine it creating an appealing or worthwhile contrast with plastered surfaces.

Yes, definitely. Common in the north. Available from various manufacturers including Emsländer, Silka itself, and others....
