Dui from the Chinese ʻIChingʼ; happiness around the table with friends. Owner and Chef Bel Coelho and her business partner Cristiano Almeida, invested in a disused building designed by Luis Fernando Rocco, to open their own restaurant in Sao Paulo. With a 1960ʼs and 70ʼs theme chosen for the furniture, the innovation was brought to this project through the chosen material to solve the acoustic problem that the building had. This was due to the ʻGraniliteʼ cement floor and glass façade that caused sound to bounce around the space too much. The solution came with Basf, a chemical company based in Germany that sponsored and supplied them with a material called Basotect; flame-retardant melamine resin foam, produced to acoustically and thermally insulates buildings, cars and trains. Usually used in high performance situations, it has been used for sensitive satellites that the Ariane 5 launcher delivers into space, for the Beijing's Olympic swimming stadium as acoustic damping in a new type of suspended structure and soon the American aircraft manufacturer Boeing. Dui was the fourth place where this material has been used. SuperLimão Studio made a cubic three-dimensional layered pattern on the ceiling of the restaurant, using different tones of purple as the colour palate. This did not only solve the acoustic problem for the restaurant but created a relaxing a sophisticated atmosphere. In addition to this SuperLimão Studio developed their product range in order to fit this restaurant. By placing a mirror at the base of the stools that would not only reflect the wine glasses that where placed on the glass surface above but also the Basotect ceiling. Bruna Albuquerque, an architect and plastic artist based in São Paulo, collaborated with SuperLimão Studio to created the tiles that where used on the bar and in the front windows of the restaurant, creating a unique environment.
