Bemutatkozás: Why do plastic windows fog up inside in winter? Condensation on glass is not a characteristic of plastic profiles, but a physical process. Water settles on the coldest surface in the room when air humidity exceeds normal levels. If the problem is ignored, black mold will appear on the window sills and seals, and the hardware will begin to rust. To eliminate the cause of the moisture, sometimes it's enough to adjust the sashes or order professional PVC window repairs, which will restore the seal and proper fit. The Physics of the Process: Where Does Water on Glass Come From? The main cause of fogging is a shift in the dew point. Air always contains moisture in the form of vapor. The higher the room temperature, the more moisture the air can hold. When warm, humid air comes into contact with cold glass, it instantly cools. Excess moisture, which the air can no longer hold, turns into water droplets. This occurs when the glass surface temperature drops to 10-12 degrees Celsius when the room humidity is above 50%. In winter, the plastic window becomes the coldest place in the wall.
