External walls of lightweight aggregate concrete with open structure
Highlights such as the light-filled rooms 2.80 cm high – with floor-to-ceiling windows that follow the generously dimensioned and timeless floor plans – provide the special living comfort of the White Villa. In addition, there are already integrated kitchens of workshop quality, private underground garages and cutting-edge building services.
Multi-talent expanded clay spheres
The main constituent of Klimapor wall elements is lightweight Liapor expanded clay spheres which are glued to each other with cement as binder in such a way that the so-called open structure of the aggregate remains as interstices. The many air voids in the interstices, as in the expanded clay spheres, themselves provide the wall elements with special lightness, but still with stability and resistance to pressure.
In addition, they provide outstanding thermal insulation and heat storage capacity for the lightweight Klimapor wall elements – as well as sound protection and F90-class fire protection. Liapor wall elements, owing to their non-capillary structure, are moreover insensitive to frost and moisture. Another advantage: “The wall elements are breathable and ensure air-humidity exchange – a decisive aspect for a healthy and comfortable indoor climate,” says Sandra Kirmse of H+L Baustoff GmbH.
Structural shell in record time
“The special challenge in producing the elements represented the round edges of the external wall elements, for which we developed special formwork,” explains Sandra Kirmse. The high degree of prefabrication and the exact fit of all elements over the total surface area of around 11,600 m² then enabled especially fast and cost-efficient construction progress.
In this way, the structural shell beginning with the ground floor was finished in the summer of 2017 within three months. Soon afterwards, all apartments could be handed over to the new owners who, since then, are pleased about their exclusive homes with maximum living comfort and special architecture in the historically significant quarter.
