Why do the windows "cry"?

Condensation on the windows in the cold season is a very common phenomenon. "Cry" and the usual windows in wooden frames, and modern plastic windows. Why is this happening? Why do windows cry? Let's look at the most likely causes of condensation on windows and how to fix this problem.

Causes of condensation

It's all about physics. "Tears" on the windows is a condensate that forms during the transition of water from a gaseous to a liquid state. Why does condensation appear on the windows? Because they are a kind of boundary between open space and the room. Different air humidity and different temperatures on both sides of this boundary cause condensation to form. This barrier is thin and, unlike walls, can freeze through. The colder the window glass, the higher the humidity in the room, the greater the likelihood that the windows will begin to "cry." But the reasons for starting this process may be several:

  • Sill covered with radiator.
  • Insufficient ventilation in the room or even lack thereof.
  • High sealing.
  • Indoor flowers.
  • Single chamber glazing.
  • Errors of installation of a double-glazed window.
  • Summer plastic window mode.
  • Manufacturing defect.

Most of these causes are easily resolved. In some cases, it is necessary to eliminate the mistakes of negligent builders or manufacturers.

Elimination of causes of condensate

Household reasons

If the window sill is so wide that it completely isolates the flow of warm air, you need to reduce its width. If for any reason it is impossible to do, then simply put closer to the window of any heater that performs the function of the battery. Thereby you will provide access of warm air to glasses.

If there are indoor flowers on your window sill, they can also provoke misting of windows. Try moving your flower pots to a different location. Perhaps after this your windows will stop crying.

Check the ventilation grilles in the room. If they are clogged with dust, clean them. Better yet, clean the vent and replace the grilles.

Ventilate the room often.Sealed plastic bags increase air humidity. Therefore, three or four times a day, open the vents for a couple of minutes or switch the glass unit into ventilation mode.

If your plastic window is equipped with a seasonal translation function, then in the cold season, be sure to switch the accessories to winter mode. Thereby you will increase the thermal insulation of the window.

If you save on the cost of the window and purchased a single-chamber double-glazed window, it will most likely collect condensate. If none of the above methods help to eliminate condensate, then replace the glass unit (but not the window!). Will help to cope with this problem and additional heating of the window.

If at installation of a window there were cracks, then repair them! Thus, you are more likely to eliminate the effect of fogging windows.

Eliminate manufacturing defects themselves will not work. There is only one way out - to change the window itself. So feel free to make a complaint to the seller or manufacturer.
