Aerogel as high performance insulation?

Aerogel was invented 1931, it is a porous solid material that is strong and does not conduct heat.

Performance as an insulator:

Composed almost entirely of gas, which is a poor heat conductor, aerogel can almost nullify the three methods of heat transfer (conduction, convection and radiation). Boasting an R-value of 10 to 30, NASA has used the material to protect astronauts and equipment, such as the Mars Rover, from the extreme cold of space. As compared to conventional insulation material, the R-values of vermiculite, rockwool, fiberglass and cellulose are approximately 2.13, 3.1, 3 and 3.1, respectively. Silica aerogel is especially valuable because silica is also a poor conductor of heat.  A metallic aerogel, on the other hand, would be less useful as an insulator.
