Due to enormous snow loads in the Black Forest region, the oversized tiled roof of the new “Badeparadies Schwarzwald” at Titisee confronted the designers and building contractors with extreme technical demands.

Nothing but roofs

Titisee ranks among the most popular destination for excursions in the Black Forest. In 2011, the area was enriched with the water park called “Badeparadies Schwarzwald”. Its external building shape can be clearly made out from a distance because it is practically made up of nothing but roofs. The aim was the design of a both aesthetic and durable roof, which meets the building’s extreme physical as well as structural requirements in this snowy environment. Two enormous pitched roofs made of clay roof tiles, which are positioned at a right angle to each other, provide the required cover and characterise the building with regard to its visual appearance and its construction. Using clay roof tiles, a traditional roofing material tried and tested in this area, made it possible to harmoniously integrate the complex into the local landscape despite its impressive dimensions.

Technical challenge

The building with a T-shaped floor plan consists of a glass pavillion with a panoramic roof that can be opened up, a long clay tiled roof with inclined cantilevering glass fronts at the gable ends and a central light strip, as well as a second, slightly smaller clay tile roof, which covers the glazed entrance area at the front. The surface area of the large roof measures about 4,000 square metres and spans across the water slide paradise. The dimension of the enormous roof landscape, however, also demanded the implementation of special technical solutions, because the trapezoidal roof structure made of laminated wooden beams supports not just the roof load but also a majority of the slides suspended from them.

Braving wind and ice

Extreme snow and ice masses of up to two metres are not uncommon in this region of the Black Forest. Primary importance was therefore attached to a winter-proof design. The socalled “Reformziegel” clay tile by Wienerberger was used in the red engobe colour for the roof. Furthermore, the new model is equipped with the integrated “SturmFIX” fixing system. The oversized roof areas have mastered the first storms and the seven metres of snow and ice, which accumulated in the winter of 2011/2012 along the eaves, without any difficulty. The consistent all-ceramic detailing of the large roof areas was developed in close collaboration between the designers, the involved craftsmen’s businesses as well as the expert service consultants from Wienerberger. Many features implemented in this roof are based on old building knowledge developed in the area, which proved to be successful with this roof.
