Title: Cembrit Patina (EPD).pdf
Cembrit boards are produced according to the Hatschek method: the base materials (binder, fibers, etc) are processed into a homogeneous mixture with water and transferred to the vats of the Hatschek machine. Rotating sieve cylinders in the vats collects a thin layer of solid material and transfer the layer to a rotating felt for dewatering and further on to the accumulating format roller. The format roller is gradually covered by layers of fibre cement and once the required board thickness is reached, the fibre cement layer, still moist and moldable, is unwound and taken from the roll.
