The perfect solution for areas that experience highland and/or extreme climates (such as the Swiss Alps or Scandinavia), where in some cases snow loads of up to 700 kg/m² can be reached. Conventional retractable roof solutions are not suitable for such high-load values. In comparison, it can be stated that the panels of the new T8000 ER series are twice as strong as the conventional T8000-series panels, and the reinforced version is up to 4 times better.
