Insulation thins down and lowers thermal conductivity

Claimed to be the thinnest insulation available today, Panasonic has introduced the NASBIS (Nano Silica Balloon Insulation Sheet), available with a thickness of 50, 100, 500, or 1,000micron and an ultra low thermal conductivity of 0.018 to 0.024W/mK.

The low thermal conductivity of convection is achieved thanks to a pore diameter which is smaller than mean free path of air (68nm), explains the company.

The sheet is made of aerogel material. This synthetic, porous material is derived from a gel, but the normal liquid component of the gel has been replaced with gas. In addition to low thermal conductivity, benefits are a low sound propagation of 120m/s, low bulk density of 0.050 up to 0.250g/cm³, high transparency of 90% up to 94% at 10mmt, a refractive index like air of 1.015 up to 1.055, as well as high porosity of 90 up to 98%.
