etfe cushion

San Francisco de Heredia will soon be home to Oxígeno, a unique recreational and commercial space that combines nature and human relaxation in a development that “will be unique in the world.” For this amazing project it was asked to us to developed a cover for the main food court of the almost 125.000 sqm recreation and shopping area.
The job was to developed an ETFE roof for 1.600 sqm, the idea, to do one big ETFE cushion!

The roof has a diameter of 45m and the ETFE material is supported by a cable net attached to a steel structure provided by the client. Very important in this project is the safety system against water ponding, a system developed by the firm 3dtex, which does not use the plastic tube inside the cushion, achieving first a better safety of the system and second a much clear and elegant architectural design of the structure.

In this way the country of Costa Rica and the city of Heredia not only became it first ETFE cushion roof but also the biggest in the world.
