Textile covers are the best solution for the expansion of any type of commercial installation. This is what the aforementioned center has done which, through tensioned sails designed, manufactured and installed by Tolder, has turned an outdoor area into a comfortable space in which to increase leisure offers. But, also, it has achieved its own personality and a decoration full of light and color. Conical tensile structures in simple shapes with open or closed sides. Most are made of open membranes for protection from rain and solar radiation. The membrane or canvas protects from inclement weather and at the same time maintains the feeling of being outdoors. Tensioned structures are lightweight because their structural stability is due to the prestressed shape rather than the mass of the materials used. Therefore they are much lighter than conventional built structures. They are transportable and temporary in many cases. The lightness and flexibility of the material allow them to be easily and quickly carried and deployed.
