In Scandinavia and Benelux, visible ceiling joints are generally accepted today, primarily due to the economic benefits of using precast concrete units. However, in Central- and Southern Europe, visible ceiling joints are to a much wider extent perceived as having an industrial and “ghetto-like” look and is one of the reasons prestressed slabs have found it difficult to penetrate the market for residential construction in these markets. Rather, cast-in place solutions or non-prestressed filigree slabs (half slabs) with a cast-in place topping are used with the economical and timely benefits of precast construction vanishing.
In Scandinavia and Benelux today, smooth and joint-free ceiling are primarily reserved for “luxury” projects. In such projects, this look is achieved using dropped ceilings systems (typically gypsum boards) underneath the slabs. Dropped ceiling are, however, both expensive to install while also increasing the height of the building.
With the SL-deck’s joint-free solution, it is now possible to achieve to high aesthetical quality from cast-in place construction with the speed and cost-efficiency of precast construction.
