4 Figure 6: The measurement of the Young s modulus and the specific BET-surface area (pore size) provide quantities that allow for an identification of trends in terms of contributions to the total thermal conductivity to be expected. The later can also be measured at ambient conditions representing a superposition of the solid phase and the gas phase contribution. The two effects can be separated by measuring the gas pressure dependence of the thermal conductivity λ(p), with λ(p0)= λ solid. Figure 7.

Table 1. GWP results for the aerogel production (0.11 m 3 ). Electricity, which used in production process, has low GWP (140 g/kwh). Production life cycles are: raw-materials (A1), raw material transportation (A2) and aerogel production (A3). A1 considers that virgin HDMSO is used by 7 % and virgin ethanol is used by 2%.

GWP results for the supercritical aerogel production (batch size 0.06 m 3 ). Electricity, which used in production process, has low GWP (140 g/kwh). Life cycles are: raw-materials (A1), raw material transportation (A2) and aerogel production (A3). A1 considers that ethanol and isopropanol is recycled and only 1% of virgin substance is used.
