The development of innovative materials aiming to achieve energy savings is a main focus in the building technology sector. In this regard, aerogel-enhanced products are often indicated as promising materials for achieving high thermal resistance in the building envelope. This paper aims to review the current state of the art of the aerogel-enhanced opaque systems. Cement-based products are reviewed as well as aerogel-enhanced renders and plasters. The focuses moves also on aerogel-enhanced blankets, which are among the most promising superinsulating systems. Comparative thermal characterization tests of several aerogel- -enhanced blankets confirm their superior performance with a thermal conductivity as low as 0.010 W/(mK). Finally, future research challenges for making aerogel-enhanced products more common in buildings are presented.
