If slats meet stars, there is lasting enjoyment. That´s how it is at one of the best spa resorts in Germany with a long tradition. Traube Tonbach covers its outdoor pool with grando and shows thereby that it focuses on the well-being of its guests and the environment. But that is not all. Sedum sprouts grow on the green roofs of the Traube. They insulate and lower energy consumption. That´s how our pool covers work, which are – like the plants – “easy to handle”. Just press a button and the three covers slide over the surface of the water. Saving energy can be so elegant!
