Description

The Royal Burgers’ Zoo in Arnhem, Netherlands, wants to create awareness for mangroves. They created the largest covered mangrove in the world and Vector Foiltec’s Texlon® ETFE covers it – again. Vector Foiltec covered the first mangrove hall, built in 1983*, and the newest is a testament to the positive results. The Royal Burgers’ Zoo went on to create several buildings with Texlon® ETFE, including the famous Rainforest, which changed the way zoos were perceived.

Texlon® ETFE roof

The energy efficient mangrove dome, with an area of 3,000 m², creates a new natural environment for various animals and plants. The unique structural frame is on the exterior of the building, which creates a smoother transition to the outside world.  The three-layer pneumatic Texlon® ETFE system with 40 transparent foil cushions (spanning up to 29 meter) allows its denizens and visitors living under the sky with natural sunlight. Moveable vents – of course with a net to keep butterflies and birds inside – are also made of Texlon® ETFE cushions.

Mangroves

Mangroves have an essential function for nature and are disappearing on a global level. Burgers’ Zoo together with the Swiss Papiliorama protects a nature reserve in Belize. The Belizean nature reserve is the model for the new Burgers’ Mangrove.

Inspiring visitors

The purpose of Burgers’ Zoo is to inspire and amaze visitors with natural environments of a variety of plants and animals – and they do this with free roaming insects and animals. The butterflies are dancing through the air and between visitors. A natural environment normally found thousands of kilometers away is closer than you think.

How it’s made – Texlon® ETFE for zoos and botanical gardens

Texlon® ETFE foils are transparent and allow high levels of light transmission into buildings. Animals and visitors can enjoy an outdoor feeling while being protected from the elements.

High levels of visible light and ultraviolet UV-A light are essential for plant growth. They pass unfiltered through Texlon® ETFE – a single layer of 100µm foil allows more than 90% of visible light and 80% of UV rays to pass through. The UV rays lead to a so-called bactericidal effect of light transmission, a natural phenomenon that kills bacteria, which means that plants and animals thrive as if they were in their natural environment.
