Retractable Systems

Motorized retractable membrane roof systems allow large areas to be flexibly closed and opened, allowing for rapid response to varying weather conditions. These systems are used in many different structures, including sports stadiums, concert halls, cultural facilities and public spaces. Here are 5 of the best projects with motorized retractable membrane roof systems in the world:

1. National Stadium (Warsaw) – Warsaw, Poland
The National Stadium in Warsaw is a world-renowned stadium with a motorized retractable membrane roof system. The roof is made of polymer-coated PTFE membrane and supported by a large steel cable network. The motorized system automatically closes in adverse weather conditions, protecting the stadium and regulating the indoor temperature.

2. Wimbledon Centre Court – London, England
The centre court of the Wimbledon Tennis Tournament has a motorized retractable membrane roof. The roof protects the court on rainy days, allowing games to continue uninterrupted. Designed using a PTFE-coated fiberglass membrane, the roof is lightweight, durable, and fast-moving.

3. Forsyth Barr Stadium – Dunedin, New Zealand
Forsyth Barr Stadium is known worldwide for its fully enclosed membrane roof. The motorized system covers a large opening, allowing sporting events to be held in all weather conditions. The membrane coating provides high durability and light transmission.

4. Mercedes-Benz Stadium – Atlanta, USA
Mercedes-Benz Stadium is an iconic structure with a motorized retractable roof system. The roof consists of movable triangular membrane panels supported by steel cables. The roof opens and closes like a flower, optimizing natural light and air circulation.

5. BC Place – Vancouver, Canada
BC Place Stadium features a renewed motorized retractable membrane roof system. The cable-supported membrane, attached to a central ring, is opened and closed by motorized mechanisms, increasing the stadium’s indoor comfort and adapting to weather conditions.

Singapore National Stadium – Singapore
Singapore National Stadium is one of the largest structures with a motorized retractable ETFE membrane roof system. The roof, supported by ropes and motorized mechanisms, allows the stadium to quickly open and close according to weather conditions.

Garanti Koza Wosarena Stadium retractable roof, designed, manufactured and installed by ETNA MEMBRAN YAPILAR in 2015, is also the first retractable stadium project in Turkey.

These projects are the best examples of the innovative and functional use of motorized retractable membrane roof systems. Such systems are ideal for covering large areas, optimizing natural light and providing flexibility to weather conditions and are used in various architectural projects.
