London Zoo visitors see rare tigers up close thanks to Specialist Glass

Visitors to ZSL London Zoo’s new £3.6million Tiger Territory have a clearer view of the rare Sumatran Tigers – thanks to the specialist glass installed in their enclosure.

The anti-reflective glass processed by ESG means that visitors can come face-to-face with the big cats without annoying reflections spoiling their view particularly on sunny days.

The AMIRAN anti-reflective glass offers less than 1% residual reflection and gives up to 98% light transmission, which is ideal for enclosures and exhibits. The glass needed to be strengthened to guarantee visitor safety, therefore ESG toughened it with a triple laminate including an SGP (SentryGlas®Plus) interlayer that preserved the clarity of the glass, whilst giving it the essential strength.

Wharmby Kozdon Architects (WKA) specified the AMIRAN anti-reflective glass from the international specialist glass technology company SCHOTT. SCHOTT had previously worked with WKA on the Galapagos Tortoise enclosure at London Zoo, where the advantages of the anti-reflective AMIRAN glass were clear.

At an amazing 2,500 sq m, Tiger Territory is five times the size of the previous Tiger exhibit at the zoo. Its inhabitants Jae Jae and Melati are thought to be Europe’s most genetically important pair of Sumatran Tigers, matched by a global breeding programme for the critically endangered species that has just 300 individuals left in the wild.

Over one million visitors a year are expected to visit Tiger Territory, and it is hoped that the new enclosure will encourage the pair to produce the first tiger cubs at ZSL London Zoo for more than 15 years.

Scott Sinden, Managing Director of ESG, said:

“ZSL London Zoo’s Tiger Territory is a fantastic exhibit, and we were delighted to be chosen to supply this exciting project. Projects like this show how versatile glass can be, and the technical developments that solve problems such as reflections and glass being too weak. We are proud to have been part of this great project – and can now claim that we can make glass tiger proof!”

John Meadows, Managing Director of SCHOTT UK said:

“SCHOTT AMIRAN® anti-reflective glass products offer a clear view – even when there are significant differences in the brightness in front and behind the glass. It reduces reflections to only a fraction compared to conventional glass. This makes AMIRAN® anti-reflective glass the material of choice for applications such as the Tiger Territory at London Zoo.”
