There cannot be one either, unless the person answering has clairvoyant abilities...now I have read through the entire thread, BUT there is no clear simple answer to the question, or I have overlooked it.
An energy consultant from the insulation industry will always answer this question unreservedly with YES. However, the actual conditions are far more complicated....Since I also have 36 cm Ytong, built in 1980, I am simply asking the question here again: Does additional insulation make sense? At least on the north and weather-exposed sides? So far I have neither mold, moisture, nor ventilation problems.
Theoretically, additional insulation reduces demand, the extent of which depends on the initial situation. Building physics aspects also play a role (the vapor permeability of the external finish (plaster)). If condensation occurs, the theoretical insulating effect exists only on paper. The same applies to the heating system. With a brine heat pump as the heat generator, the measure will probably have only marginal success. With a heat generator based on the combustion principle, e.g., oil or gas, theoretically more so. However, if the heat generator was already oversized, additional insulation can possibly lead to a deterioration of the annual efficiency of the system. The theoretically intended saving effect is practically only partially effective, so one has to ask whether the actual result was really worth all the effort? With additional insulation, adjustments to the heating system are often required.
...Please don’t go off-topic in your answer. Thanks!!!!!
You probably won’t get the truly valuable "non-plus-ultra solution" for free in three words
