Aerogel

---

Aerogel, or frozen smoke, is a synthetic silicon-based material derived from a gel, in which the liquid component of the gel has been replaced with a gas. It is 1000 times less dense than glass and 39 times more insulating to heat than fibreglass. It is used as building insulation in walls and windows, thus improving energy efficiency. Scientists are also looking at if aerogel can be used as a building material on Mars.
