Mold – it can happen quickly

Mold can quickly become a problem under the right conditions, especially when humidity, breeding grounds such as plasterboard or wallpaper and spores in the air come together. These factors not only promote germination, but also accelerate the growth of the fungi, which can lead to health risks, especially in building structures. Understanding the relationship between humidity, temperature and substrate quality is crucial to effectively prevent the growth of mould and minimize its potential dangers.

The three main factors influencing the germination and growth of mold are: Food, organisms and climate/humidity. The following diagram shows the three influencing factors:

The existence of mold spores in the air (organisms): spores occur naturally everywhere. If the concentration in the indoor air is too high relative to the outdoor air, a mold source in the room is to be expected.
The presence of a breeding ground (nutrition): excellent breeding grounds are plasterboard and cellulose (mold germinates very poorly on clean glass).
The moisture on the surface of the building component (climate/humidity): excessive humidity combined with thermal bridges, water damage or a lack of insulation are important influencing factors for mold.
