ECOMUR® FLEXSLAB

Multifunctional and resource-optimised storey slab When you enter ‘STEP2’, the ceiling is the first thing that catches the eye. Designed as a ribbed filigree slab, it allows spans of up to 14 metres and is therefore particularly suitable for office and high-rise construction. The slab was developed by the architectural firm ROK together with the engineering firm WaltGalmarini and Stahlton Bauteile AG. With the help of specially developed digital planning methods and 3D-printed formwork for the prefabricated elements, it was possible to reduce both the amount of material used and CO2 emissions by around 50% compared to a concrete flat slab with the same span. In addition to its structural function, the ceiling also fulfils other tasks: Integrated, 3D-printed acoustic boxes, which are filled with a mineral foam from BASF for sound insulation, ensure pleasant room acoustics, despite the reverberant surface. The slab also serves as a thermal storage mass, thus equalising the room temperature and is an important part of the unit's energy concept.
