Do plastic windows promote the appearance of mold in the premises?

Among the myths surrounding PVC windows, it is often mentioned that they can encourage mold to appear in enclosed spaces. Several factors favor the development of microfungi in glazed rooms. Firstly, the rooms must have high humidity and at the same time a lack of adequate ventilation.

In addition, windows that are too tight without a micro-ventilation function can promote mold growth. When all of these factors occur at the same time, moisture can condense and settle on cold spots such as exterior walls, window edges or the window frame area on the wall.

On the other hand, the damp walls of the heated room are an ideal habitat for micromycetes. But does that mean plastic windows are the cause of indoor mold? Of course not. The culprit is insufficient ventilation of the house. Today, however, there is hardly a PVC window model that is not equipped with a micro-ventilation option. In the Veneo offer you will find cabinets that have this option, in addition to high-resistance PVC profiles and low-emission glasses with argon gas between the glasses as standard.
