Images credit Birdair Tensotherm Back in 1967 at Expo67 and then at the Munich Olympics in 1972, German engineer Frei Otto wowed the world with his tensile structures, roofs of fabric that could cover huge spans with light weight. Single layer tensile roofs were beautifully translucent, but had little or no insulation value. Air supported roofs, a form of tensile structure invented by Walter Bird, suffered the same problem; as we saw in the Minneapolis Metrodome , when insulated, they lost all of their transparency. But what happens if you combine tensile roofs made of PTFE (teflon) fiberglas fabric and the sexiest insulation around, Nanogel ? You get Tensotherm. ... Read the full story on TreeHugger
