The basic Igloo Satellite Cabin, weighing 250 kg and 3m wide x 2.1m high, is pre-fabricated, insulated and made from 8 wall panels and 4 floor panels. The whole Igloo is bolted together and secured to ground anchors by 8 wire tie-down lines. Igloos can be extended and interlinked with tunnels.
Units can be flown fully assembled by helicopter, and are ideal short-term accommodation for exploration, research and ecotourism. Igloos have been in use since 1982.
