Retractable Roof Systems
| Through a so-called "Retractable Roof" the building (e.g. swimming hall) fits to the external weather conditions: In case of adverse weather conditons the roof is closed but - nevertheless - natural daylight can still enter throug an integrated roof segment of transparent foil cushions. |  |
| On sunny days, the entire roof can be opened by a special drive and control technology and thus gives the visitor a kind of "Open-Air Feeling". (Pictures: Dr. Krieger Architekten & Ingenieure, Velbert) |
