Aerogel – The building material of the future



UPDATED (19/11/2011): There is a lighter material than aerogel! It is named “ultralight metallic microlattice”, currently flaunted as the lightest material on Earth! View the full news article here: Click! 


About Aerogel


Aerogel is a synthetic porous material derived from a gel, in which the liquid component of the gel has been replaced with a gas. The result is a solid with extremely low density and thermal conductivity. Aerogels are almost completely composed by gas!


Properties of Aerogel:

  • Extremely low densities (can be made lighter than air!)
  • Excellent heat insulation properties
  • Prone to shattering
  • Hydrophilic (generally)

Note: There are many types of aerogel. e.g. silica, carbon, alumina, etc.
