Hello,
we are planning to build soon. Since we are constructing a KfW 70 house with 30 cm (12 inches) Ytong exterior blocks and therefore will not add any insulation to the facade, my question is whether I can lay the brick veneer directly onto the Ytong or if I need to leave a 1-2 cm (0.4-0.8 inches) gap?
My concern is that if I use brick slips, they are glued directly to the Ytong, but standard 11.5 cm (4.5 inches) brick units are usually laid with a certain gap. Unfortunately, I only find this advice when insulation is involved, which I do not want, as I have read a lot of negative things about that, like mold, moisture, etc.
So should the brick be glued directly to the Ytong or installed with a gap?
I hope someone can help me!

For us, the facing bricks will be installed over insulation (I think 12cm (5 inches) insulation).
Beforehand, spikes will be attached to the walls to ensure the insulation adheres properly.
It will not be glued. The bricks will be applied, among other methods, onto a supporting structure.
So, it’s not that simple.
Our walls are precast concrete, 25cm (10 inches) thick.
How many square meters of facing bricks are you planning to install?
Just glued on?
