Window replacement in old buildings - Which glazing?

Wall insulation could lead to mold formation.

Mold appears with very well insulated (double-glazed) and excellently insulated (triple-glazed) windows. This is due to today's airtight construction methods and incorrect ventilation behavior. If it's only about mold, leave the old and somewhat drafty windows in place.

Of course, it is not only about the possible mold infestation.

The old windows are now 36 years old and equipped with wooden frames. The window replacement should primarily be carried out with a view to saving energy costs.

I have now received a response from the expert, and he also advises me to use triple glazing.

Mold comes from poor ventilation and heating, not from good windows. The windows are sealed, whether double or triple glazed. The difference then lies in where the water condenses. So ventilate properly and that's it..
