We cover here two real examples of mold and condensation problems, with thermal insulation installed on the inside of existing masonry walls. In both cases, the solutions were chosen on an empirical basis, and turned out to be worse than the problems they were trying to mitigate.

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.
Energy efficiency and barbaric marketing
Over the years, the construction industry has been moving in the direction of energy efficiency and environmental sustainability. However in some cases, this change has happened only from a marketing point of view: with this article, we provide you with two interesting stories.
