Thermal bridges: the temperature factor fRsi

We continue our series of articles on the topic of thermal bridges: this time, we illustrate the fRsi value, which describes the thermal ”strenght” of a node under the point of view of internal surface temperatures.

As we have explained in a previous article, the PSI value describes a higher or lower heat flow caused by a discontinuity in the thermal envelope – a thermal bridge – the fRsi factor is of primary importance for health and comfort considerations. Read More
