Daylight System for the Elephant House by JET Group

The 664-m²-large roof surface was as much a challenge as the elliptical shape of the dome. After structural investigations and preliminary planning, it was decided to opt for a steel structure. This is largely immune to the ammonia vapours and is intended to ensure a longer service life. In order to bring as much daylight and fresh air as possible into the hall, BA glazing systems and 16 Ventria 3 system flaps from the JET Group were used. To form the round glass dome, trapezoidal elements tapering upwards were necessary. The encircling thermal separation and the ­optimised chamber and bridge design of the frame and sash profiles also ensure thermal insulation. www.jet-gruppe.de
