Hygrothermal characterization of high performance Aerogel-based internal plaster

The development of novel high-performance thermal insulating products represents a key-action within the deep energy retrofit strategies on the existing building stock. In the framework of the Horizon 2020 project Wall-ACE, a highly efficient thermal insulating plaster, based on silica aerogels, has been developed. In this paper, the development process aimed at achieving a thermal conductivity lower than 0.030 W/mK is presented. Moreover, the hygrothermal characterization process aimed at assessing the data for the dynamic heat and moisture transfer (HMT) simulations, according to EN 15026:2008, is described.
