Is silica sand a good insulator?Jan 07, 2020 · Is silica sand a good insulator? Unlike metals such as gold and iron, silica is a poor conductor of both electrons and heat. Because air has very low thermal conductivity and silica has low thermal conductivity, they are great materials to use in insulators. These properties make nano aerogels one of the best thermal insulators known to man.
