Researchers at the Fraunhofer-Gesellschaft have developed a new way of drying damp walls due to water damage. FastDry®" is a rectangular insulation board that is attached to the damp wall after water damage. In the process, the resulting water vapor passes through the insulation board with its integrated heating wire. According to the researchers, the heat remains in the wall through the insulation.
According to the researchers, the advantage of the noiseless insulation board made of commercially available mineral wool, developed by project manager Andreas Zegowitz, group leader for thermal parameters and climate simulation in the Hygrothermics department, and his team, is that it requires little electricity and does not heat up the room unnecessarily. In addition, mineral wool is not combustible. The insulation board therefore also meets strict fire safety regulations, they say.
When the wall is dry is measured, among other things, by means of a temperature sensor that records the surface temperature of the wall. The insulation board can then be switched off either manually or by remote control. According to Andreas Zegowitz, if the temperature and energy absorption remain "constant over a period of 24 hours, for example [...] the wall can be considered dry.
