Mold and condensation: if the solution is worse than the problem

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…

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…
