Effertz stacking doors offer a largely smooth door leaf and thus good possibilities for surface design. They can be painted or foiled and can thus be adapted very well to the structural environment. This is of particular interest if the door is often closed and therefore visible. Since the door leaf sections are stacked one behind the other when opened, the surfaces do not touch and there are practically no abrasion marks.

Thanks to the stable door leaves and low-friction running, the Effertz stacking doors have successfully passed the highest durability function class of 200,000 cycles (use category 5) in a standardised test.
