Icewall One, the Australia-based manufacturer designed these pre-fabricated remote shelter to create an instant and transportable home away from home for scientists based in inclement climes. But they don’t have to function only as research stations. Eco tourists like them too. Made of lightweight fiberglass, the modular igloo consists of 8 molded wall panels with 4 self-supporting floor panels. The fiberglass walls have polyurethane insulation with an R-value of a little over R-5; better than a tent, and there is ventilation at the top.
