Two characteristics that determine how effective a material will perform as an insulator is surface area and loft.
- Surface area is basically the same principle as layering your clothing to stay warm. The greater the surface area the better the insulator. Produced using advanced nanotechnology, the surface area contained in just one cubic in. of Aerogel is approximately the surface area of a football field.
- Loft is the amount of trapped air between the insulating particles.. Aerogel is 50 - 99.9% air and is the least dense solid known to man often referred to as "frozen smoke"
