Silica aerogel is known as the best material for insulation at present. The diameter of pores in aerogel is smaller than the mean free path of air molecules, so the air molecules in aerogel is almost in static situation, which avoids the air convection leading to the heat loss; And the low density character and the nano net structure of bent path in aerogel also effectively stop the heat transmit in both solid and air way, moreover, the infinity of pore walls in aerogel could reduce the thermal radiation to the minimum. Basing on the above three characters, it almost stops all the heat transmit ways and makes aerogel the best insulating effect comparing with other insulations, for its thermal conductivity is lower than 0.013W/m·K, even much lower than that of static air 0.025W/m·K in normal temperature.
