It is important to control the humidity. For a first orientation, experts recommend commercially available room humidity meters (hygrometers). If the humidity rises to over 65 percent, it must be ventilated. If possible several times a day. If more than 65 percent humidity is permanently present, there is a risk that mold will form.
Thermal insulation reduces the energy requirements of buildings and leads to higher surface temperatures on the inside and thus lower susceptibility to moisture and mold damage. It is an absolute myth that thermal insulation leads to mold damage. If mold damage occurs in connection with new insulation, it is usually not the insulation but the denser window or roof and the lack of ventilation that cause it.
For new windows, therefore, a ventilation concept should always be created and implemented. Even when it’s cold outside, you should ventilate several times a day – 5 to 10 minutes are enough as shown by Pest and Building Inspection Melbourne.
