SANTIAGO BERNABÉU STADIUM
A RETRACTABLE ROOF FOR THE HISTORY OF EUROPEAN FOOTBALL
The Santiago Bernabéu Stadium has undergone one of the most ambitious transformations in contemporary sports architecture. IASO has had the privilege of contributing to this new chapter, bringing its technical expertise in textile architecture through the design, manufacture, and installation of the retractable textile roof that crowns the new stadium. A project that embodies innovation, engineering, and spectacle, redefining how sport is experienced in Madrid and around the world.
IASO was responsible for the design and implementation of the textile system that shapes the retractable roof, composed of PTFE cushions capable of deflating and retracting to allow full opening over the playing field. This advanced solution provides weather protection, optimised lighting, and a futuristic aesthetic in perfect harmony with the stadium’s new metal façade.

TECHNICAL AND FUNCTIONAL INNOVATION
IASO’s intervention at the Santiago Bernabéu represents a technical milestone in mobile textile roofs. The system developed enables the automated inflation and deflation of PTFE cushions, which fold through a mechanism synchronised with the roof structure. This solution combines precision engineering, climate control, and ease of maintenance.
The modular design and applied technology ensure durability and resistance to wind loads, snow, and adverse weather conditions, without compromising the structural lightness that characterises textile architecture. Coordination with the metal and mechanical structure teams has been key to achieving seamless integration.
INTERNATIONAL BENCHMARK IN SPORTS ARCHITECTURE
The new Santiago Bernabéu has been widely recognised for its futuristic vision, multifunctional character, and integration of advanced construction systems. In publications such as ArchDaily and The Plan, the stadium has been analysed as a model of urban and technological transformation. IASO’s intervention is part of the set of innovations that have made this evolution possible.
