Do white PVC windows turn yellow?
PVC (polyvinyl chloride) or polyvinyl chloride is a polymer used in the manufacture of plastics. It is used in various industries including windows and doors. Although it has been used in the manufacture of windows for more than seven decades, and the technology of PVC window manufacture has changed dramatically even during this time, there are still many myths about it. Let’s see the most popular ones.
For years, white plastic windows were the most popular. Over the years, prolonged exposure to sunlight and air pollutants (e.g. sulfur dioxide and trioxide, nitrogen oxides or carbon monoxide) has caused their frames to lose their snow-white hue. Because? The polymer structure of polyvinyl chloride plastic deteriorates, which manifests itself, among other things, in the yellowing and darkening of the frames.

More myths about PVC profiles:
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.
Another possible reason for the appearance of mold in the house can be a heat leak, which is due, among other things, to housing made of poor-quality materials.
