The honeycomb windows made of concrete were a special design. Honeycomb windows were reinforced, window fronts with narrow-profiles used in prefabricated construction. They were statically safe, weather-resistant, and required no maintenance. Here, too, the slogan applies: "Install and never worry about it again!" The range was primarily aimed at the industrial sector, and was used, for example, in factories or in the properties of the German armed forces.

Another special form was widely used: decorative bricks. They were available in trapezoidal, conical or circular shapes, and were used as façade cladding, or to create ornamental light walls, or as decorative elements for staircases, connecting walls and other representative spaces. They could be glazed or unglazed. Architects were enthusiastic about the diverse design possibilities of decorative stones. Decorative stones were often used in religious buildings. In the course of the 1960s, they became a defining element of contemporary architecture.
