Slat stack heights are gaining more and more importance in the construction sector with regards to legal requirements as to thermal insulation. The slat stack height is of decisive significance for planning the shaft or cover panel height.

A dynamic and distinctive design visually breaks the height of the slat, which gains a very filigree appearance – the E 80 A6 S, both modern and expressive. The timeless design of the bottom rail clearly reduces the slat stack height and scores thanks to its positive effect on the energy balance.
