Since its inauguration in 1958, the lush vegetation and animals from Asia and the Americas has made the tropicarium at Luisenpark in Mannheim (Germany) a popular attraction. 13 years ago a gradual renovation was started by replacing a large portion of the glass roofing and facades with high-quality polycarbonate sheets. Today the sheets have continued to demonstrate their indestructibility and quality despite being exposed to extreme conditions. The weather-resistant sheets still do not show any signs of yellowing and offer optimum translucency. The UV properties of the polycarbonate sheets ensure a consistent temperature inside the tropicarium. For such reasons the roofing has been awarded by EPSE (European Polycarbonate Sheet Extruders).
