Isn't there some panic being made? The Marienkirche Lübeck, as far as I know the largest brick cathedral in the world, is made entirely of very absorbent clinker and has stood there since the 14th century.
Why is the original name of the manufacturer not simply stated in the building notice? It explicitly contains "braun", so it should pass without contradiction, right? How can the house construction company set a different name for the material there?
