Berlin’s renovated Tropenhaus botanical garden uses special UV-transmissible glass

One of the largest self-supporting display greenhouses in the world Following the renovation of the Grand Pavilion (das Große Tropenhaus, first built in 1906) at Berlin’s Botanical Garden, daylight enters through hundreds of small, heat-insulating yet highly light-permeable glass panes onto one of the world’s most significant collections of rare and endangered tropical plants. The inner panels used in the double-glazing for the overhead sections of the pavilion are made of laminated safety glass using stiff and strong SentryGlas® ionoplast interlayers. For the first time in Germany – following its “special approval” – a special “UV-transmissible” grade of SentryGlas® is used for this application, thereby sustaining the active growth of the plants and safeguarding their preservation
