Aerogel is known as the best thermal insulation material in the world. Micro porosity makes Aerogel an efficient thermal insulator. Aerogel's nano cell diameters are between 50-100 nm and these nano cells limit air molecules movement. When the air molecules interact less with each other, the heat flow is reduced. Convection and conduction heat transfer is limited because of porosity of Aerogel.
Thermal conductivity is composed of 3 factors, conduction, convection and radiation. Levron Aerogel contains air more than 90%, having extremely low weight thus Levron Aerogel has excellent thermal conductivity.
