Steaming up inside the window is very unusual under certain conditions - especially in the cool season.
Normally, however, condensation disappear without leaving any residuum. If the condensation of the window continues, there is another reason for it. Inside the double glazed window air could enter at the bonded joint or another point and would need to be replaced.
Condensation inside the double glazed window
Acrylic glass is an organic substance that can absorb water in molecular form. This means that water penetrates through the pane and increases the humidity in the area of double glazing. If it gets colder outside, the air between the panes cools. The excess moisture settles at the coldest point, i.e. the inside of the outer pane.
Tip:
Humidity is affected by air circulation. But you can also increase the temperature of the room. When cold air is heated, it can absorb the free water vapor. Your window therefore has no error when condensing water is created between the two panes. However, you have to be patient before the formed condensate disappears completely.
