Usually the so called Hatschek process has three to four rotating screens. On the surface of each of the rotating screens, supported with suction inside the drum a thin layer of the slurry is created, approximately 0.9 mm. From the screens the thin fibre-cement layers are transferred to a rotating felt on top of eachother.

Autoclaved fiber cement (FC) boards manufactured using the Hatschek process are commonly used as building products such as siding and shingles. Despite their advantages, these products may exhibit low ductility and volume instability. A common, yet expensive, method for improving ductility is increasing the fiber content.
