We pioneered the use of a really good insulating material to keep our plants warm in the Biomes. The hexagonal cushions on the steel structure trap air between two layers of ETFE (short for ethylene tetrafluoroethylene) which act as a thermal blanket.
To keep our visitors and staff warm, we’ve insulated our buildings with recycled newspaper. We also created a green roof on top of one our staff buildings behind the scenes, which helps keep it warmer in winter and cooler in summer. Birds and insects like it too.
Our buildings were designed to need as few construction products as possible. For example, the Biomes’ hexagons copy nature’s honeycombs: maximum strength using minimum materials.
