retractable membrane roof for the no.1 court in wimbledon made by seele

The heart of the No.1 Court refurbishment project is the 6,000sqm retractable membrane roof over the entire stadium. A highly translucent material was needed so that even during rain, with the roof closed, the players could still enjoy optimum playing conditions. Therefore, a very exclusive material was chosen: a PTFE membrane woven from Teflon™ fibres. This material offers the best possible properties for this purpose, as it is translucent, extremely hardwearing and dust- and dirt-repellent.

The roof required a total of 10 main membranes, 11 so-called drainage membranes, 80 batwing membranes for waterproofing the sides of the roof and a vertical membrane for the southern end of the roof. Over a length of 65m, the membranes are fixed to the 11 steel trusses that span across the stadium. The membranes are tensioned by steel cables (33t preload) so that they always remain free from creases and folds at any position of the roof.

  • The structural calculations for the roof had to take account of the different roof positions and hence different load cases. In contrast to a normal roof, this membrane roof does not have just one fixed position; instead, its sliding function means it is subjected to different loads at different positions (open, 25% closed, 50% closed, 75% closed or fully closed). The 6,000sqm membrane roof can be closed in just 8 minutes, which in future will prevent matches having to be interrupted during rain.

    With the project No.1 Court at Wimbledon, seele realized another project in the field of retractable membrane roofs and creates a further milestone in stadium construction and membrane architecture in addition to the Olympic Stadium in Peking.
