I am concerned about the reported brittleness of Aerogel and the possibility of air leaking into the vacuum in vacuum panels. However their high insulation values mean that I have to investigate them.
Hi Sahar. Aerogel is extremely brittle and also susceptible to water damage, therefore placement has to be correct. Even when placing in cavities Interstitial Condensation has to be accounted for. Cost of Aerogel is rather prohibitive and the derivative (stranded) is no better in performance than Phenolic or Polyisocyanurate insulation k = 0.02W/mK. As for the vacuum panels in the buildings they should perform as well as double glazed units, some manufacturers already are offering vacuum core double glazed units, esily distinguished from other DG units by small rod supports between two panes of glass.
Some manufacturers propose ready-to-use products inclcorporating aerogel. There are galzings (double pane glazing with aerogel inbetween) and insulating mats, You will find these companies by searching with "aerogel"
