An award winning addition to the Johannesburg skyline, Sandton City is the first project in Southern Africa to utilise Texlon® ETFE technology. Sandton City’s prolific expansion is amongst the most environmentally conscious projects in South Africa and demonstrates the revolutionary capabilities of Texlon® ETFE.


Designed by RTKL in the United Kingdom and implemented by MDS Architecture in South Africa, the striking Protea Court roof consists of white, clear and fritted Texlon® ETFE cushions. The cushions are permanently inflated, ensuring wind resistance and insulation, and restrained within profiled aluminium extrusions which curve to the contour of the steelwork.


Combining bold, elegant design and innovative technology, the domed Protea Court roof optimises solar shading and light transmission in its use of multiple layers of Texlon® ETFE foil. In addition, the roof, 44m in diameter and sloped at 11 degrees, incorporates 295m² of LED Lights. A recyclable, self cleansing and low carbon alternative to glass, Texlon® ETFE was selected for its outstanding environmental characteristics.


We pride ourselves on being the only Texlon® ETFE manufacturer with an independently verified Environmental Product Declaration (EPD) in accordance with ISO 14025:2006 and EN15804. An EPD is a voluntary document, focusing on the environmental impacts associated with the manufacturing of a product or system, and demonstrates that a product has been subjected to rigorous testing to ensure quality.
