Abstract

At ambient temperatures, transparent silica aerogels as well as translucent granular fillings are excellent superinsulating spacers if evacuated. Thus their use in windows and covers for passive solar systems is extremely promising. Thermal loss coefficients under variation of radiative temperature, sample density, boundary emissivity and internal gas pressure are presented. Furthermore, the scaling of the solid conductivity with density is discussed.
