High performance aerogel containing plaster for historic buildings with structured facades

摘要

This contribution reports on ongoing efforts exploring the potential of aerogel-based plasters on historical facades. As a case study, aerogel-based plaster was applied without reinforcement meshes to a small area in the historical main building of the Vienna University of Technology. The objective is to examine the long-term behavior of the plastered surfaces. For this, a monitoring infrastructure has been implemented, which enables the in-situ measurement of temperature, humidity, and heat flux within different layers of the construction using a wireless sensor system. These measurements are intended to offer a before-after comparison of the thermal behavior of the treated components.
