In cooperation with Fixit, an aerogel render with a low thermal conductivity of 28 mW/(m·K) was developed. It is commercially available under the name of Fixit 222. In the render, aerogel granulate with a thermal conductivity of approximately 20 mW/(m·K) is embedded. The aerogel render opens completely new possibilities in the renovation of historic or protected buildings: with only a thin layer of the render – often times substituting the existing render – the U-value can be decreased drastically. Thus, a higher thermal comfort and a reduction in heating energy can be achieved.
