Indoor humidity and ventilation
If, as mentioned in chapter 6, the component temperature drops and the ambient air is no longer able to absorb the moisture, condensation will form. A temperature of 12.6 ºC has proven to be critical. Using special software, the surface temperatures are determined in a building connection and connected to form a line, the so-called isothermal curve.
In the past, it was commonly referred to as the 12 ºC isotherm. More precise scientific investigations have now led to the above-mentioned 12.6 ºC. Popular science has agreed on the 13 ºC isotherm.
