Any window, no matter what material it was made of, requires some maintenance. And windows made of metal-reinforced plastic are no exception. Caring for such structures is not so difficult, but it must be made with certain rules.

Thanks to such measures, the seals will be elastic and have water-repellent properties for a long time.
