gorrlla.pngWestern lowland gorillas from Central Africa are a main attraction at world-renowned Bristol Zoo. The zoo is proud to have 6 of them, each one up to 2 metres tall and 180 kg – one might say massive animals – and when they charge around or jump up and down to play or show who the boss is, they are really impressive!

So when the zoo decided to renew the gorillas’ enclosure with glass which would allow very close, but safe, contact between visitors and animals, there was a technical challenge.

A glass tunnel, made of framed panels, built inside the gorillas’ enclosure allowing visitors to see themgorilla1.png from underneath, as well as left and right, was the chosen project. It had to be a particularly solid structure, able to support super heavy weights and incredible forces plus prevent any biological leak on visitors.

Kiteglass and Everlam designed a 50.56 mm-thick laminate construction:

  • 12 mm toughened glass
  • 1.52 mm PVB
  • 12 mm toughened glass
  • 1.52 mm PVB
  • 10 mm heat strengthened glass
  • 1.52 mm PVB
  • 12 mm toughened glass

Leroy Reed, Managing Director of Kiteglass: “We wanted a third party to validate our laminate construction so we asked Crossley Consult Ltd. Using nonlinear Finite Element Analysis, their conclusion was that the construction of the laminated glass and support met the requirements.”

Luc Moeyersons, Technical Programs Manager at Everlam: “The collaboration between Everlam and Kiteglass has been excellent. Together, we produced a highperforming laminated product that allows Bristol Zoo visitors to go as near as possible to gorillas and enjoy amazing views, all in complete safety.”
