Large Scale Laboratory and Field Tests of Aerogel Renders

Abstract

Within the framework of the European project Wall-ACE a large-scale laboratory test (EOTA-Wall Test) was performed. Additional a test field in Switzerland was equipped with six different aerogel renders by the project partner AGITEC. Laboratory walls and test field were equipped with sensors to monitor in real-time climate, heat flux, temperature, relative humidity, and at the laboratory tests additional material moisture. The data allow calculating U-values and material parameters as well as drying behaviour of render and substrate. During and after the artificial weathering in laboratory the renders were subjected to visual inspection and mechanical adhesion tests. The performance of the aerogel renders will be assessed and compared with results on conventional insulation renders.
