Aerogel-Based Renders and Plasters as New Insulating Materials in Buildings

Energy consumption in building section has the most contribution of total energy consumption in many countries. Efficient insulation of building is an attractive way to reduce the heat losses from buildings. In this way aerogel based insulating materials have found promising applications. Various studies have been done to develop the aerogel based plaster and renders and to investigate theirs thermal, acoustic and hygrothermal performance. This paper reviews the investigations on the aerogel-based plasters and renders as attractive insulation materials which can be used on the inner or outer surfaces of walls and presents the performance of these new patented insulating materials in comparison with the convectional renders and plasters. From the viewpoints of investigated performance criteria, various studies have shown superior and more desirable results for aerogel-based coatings rather than convectional renders and plasters.
