Hello,
We are currently trying to decide which type of facade construction is preferable. The two facade options are as follows. It is assumed that the costs are the same, and any gains or losses in space can be neglected. The focus is solely on the advantages and disadvantages of the facade construction itself.
1.) 17.5 cm (7 inches) Poroton, mineral wool insulation, facing bricks. Total construction depth 44 cm (17 inches)
2.) 36.5 cm (14 inches) Poroton, brick slips. Total construction depth approximately 38.5 cm (15 inches)
In both cases, the result is a KfW 55 standard.
Is it possible to determine which construction is more valuable? Please explain.
Best regards,
Ralf

Actually, the topic has already been mostly covered in the discussion.
But for the sake of clarity, once again:
-> Collectors are used for heat generation and, as mentioned before, they are now installed on almost every new build to secure the share of renewable energy and also to meet KfW 55 standards with a gas boiler. In most cases, in my opinion, this is rather inefficient, but for many it is a must in combination (also because most probably don’t offer alternative options, even though they do exist...)
-> In photovoltaics, we talk about modules, which — unlike the previous option — generate electricity. This requires a high initial investment, but if you have researched the topic and didn’t buy a golf car at Porsche prices, the system pays off within a reasonable time and depending on the orientation can make a significant positive environmental contribution. I don’t expect more from such a system because I go to work every morning to earn my living.
And yes, I guess the knee wall is meant here. I’m probably not 100% familiar with the term. But that doesn’t really matter as long as the tradespeople do their work properly.

....and then everything turned out completely different after all.
At the beginning, I mentioned that the seller’s assessment was that the thin brick veneer (slip bricks) facade would cost about the same as the full brick cladding for a house with the same living area. Today, surprising facts have been established.
For background, the general contractor’s offer included facing bricks (NF size) from the Röben brand, 650 pieces per 1000 bricks.
The additional cost from a plastered house to one with facing bricks would have been approximately 8,000 euros for us. However, since we chose the Amrum Antik facing brick from Vandersanden in WDF format, it ended up being a bit more expensive – our house would have cost about 11,000 euros, so 3,000 euros more for the facing bricks, more bricks, more work, etc.
In comparison, the thin brick veneers cut from the same stone were expected to provide at least some space savings, although not much more.
When I just saw the offer, I almost couldn’t believe it, because the thin brick veneers are an additional 15,000 euros more expensive than a simple facing brick cladding! This comes from the extra labor involved and because it is supposedly more complex to precisely install a flat wall vertically with thin brick veneers than to clad a house with facing bricks...
As I said, it doesn’t make much sense logically, but it’s definitely interesting, and this naturally made our decision very easy. Since my heart was already set on a fully faced facade, the result is just right.

As mentioned: thin brick slips are applied to the façade, while full clinker bricks are stacked. Yes, that does make a difference because with brick slips you need to have a smooth substrate (or create one). Therefore, one method is more suited for retrofitting, and the other for new construction. The labor cost weighs more than the "price per kilogram" of the brick.
Exterior thermal insulation composite systems (ETICS) are also tricky due to the deviation of the brick size from the planning grid.
