Condensate is moisture collected on the surface of the window. Moisture, in turn, is the dampness in the air. What does it mean and how it relates to the windows? The fact is that in the warm air that fills the room contains a small amount of steam that settles on the windows. This is what we call «foggy windows». Plastic windows have not only pluses, but also some disadvantages. People choose plastic windows because they are a good soundproofing tool. Their sealing allows us to avoid extraneous noise from the street. But, the whole irony is that this very sealing does not allow the room to ventilate.
