Hello,
we are planning to build with Ytong, and a key aspect is the possibility of fixing brick slips or veneer bricks. I haven’t found any standard detail from Ytong, only the construction method for a traditional brick wall (Ytong + insulation + brick). Does anyone have experience with such a construction?
I don’t think directly fixing the brick slips to Ytong is practical. Ytong is definitely a porous material and needs to be well protected from the outside. Perhaps at least with an external render or even an external thermal insulation composite system (ETICS / EIFS). Two concerns worry me:
1. The brick slips are fixed with adhesive. How well does the adhesive hold up under varying temperatures and weather conditions? How durable are they overall?
2. Possible issues with mold growth, since instead of just Ytong 36.5 cm (14.4 inches), multiple layers would be required. Will the combination Ytong + ETICS + brick slips work?
3. Would the option of Ytong 36.5 cm (14.4 inches) + external render + brick slips be feasible?
Thank you.

Veneer bricks are actually more of a makeshift solution. They imitate facing bricks where there aren’t any. They don’t save on labor costs compared to real facing bricks. So, why not use 24 cm (9.5 inches) Ytong blocks, insulation, and real facing bricks? That is definitely the better system.

Thin brick veneers are essentially a workaround. They imitate full bricks where there are none.I wouldn’t put it quite so bluntly,Nordlys schrieb:

Thin brick veneers are a product for situations where brick is desired but, for various reasons, was not planned in the full thickness or should add less to the overall wall thickness. So, they are used for retrofitting or as a decorative surface layer in new construction. Applying thin brick veneers directly onto render is pointless, as they are meant to replace the surface finish rather than the render itself, and are used where the wall thickness has already been fully addressed in a monolithic manner. Thin brick veneers as a facing shell do not work because they cannot be laid like bricks but only "tiled" on. In theory, they could be mounted as a curtain wall on external thermal insulation composite systems (ETICS, also known as EIFS), but for that you would have to find at least one fool willing to guarantee the durability of such a structure—and obviously find a suitable adhesive. ETICS, however, are not designed for curtain walls but, as the name “system” implies, for installation directly on the structural masonry shell. In that case, I would choose the material of the structural masonry shell so that it can be dimensioned slimmer thanks to ETICS. In my opinion, a monolithic wall plus ETICS is a recipe for a so-called "Kevin tax" (unnecessary extra cost)!Therefore, if ETICS is used in new construction, in my view it makes more sense to use brick as a facing shell, with the structural masonry shell dimensioned accordingly. The “S” in ETICS stands for “System,” meaning the wall construction is considered as a whole. Since the possible combinations are numerous, while the applicator’s experience is often limited to fewer varieties, you always end up with the question of how the installer’s “answer” to the brick mantra looks.

I specifically mean no composite system, but Ytong, glass wool, an air gap, and facing brick. This is the common construction method here.This only works with full-size facing bricks, not with brick slips.https://www.instagram.com/11antgmxde/

For this reason, the question is whether there is a significant difference in price and durability between the two options:
1. Ytong 17.5 cm (7 inches) + insulation 6 cm (2.5 inches) + air gap 1 cm (0.4 inches) + clinker brick 11.5 cm (4.5 inches) (36 cm / 14 inches total)
2. Ytong 36.5 cm (14.5 inches) + exterior render 1.5 cm (0.6 inches) + clinker brick slips 1.5 cm (0.6 inches) (39.5 cm / 15.5 inches total)
1. Ytong 17.5 cm (7 inches) + insulation 6 cm (2.5 inches) + air gap 1 cm (0.4 inches) + clinker brick 11.5 cm (4.5 inches) (36 cm / 14 inches total)
2. Ytong 36.5 cm (14.5 inches) + exterior render 1.5 cm (0.6 inches) + clinker brick slips 1.5 cm (0.6 inches) (39.5 cm / 15.5 inches total)
