What Causes Windows to Fog?

Your windows are designed to provide you with a clear and beautiful view of the outside world. When a window is fogged and covered with condensation, you are no longer able to enjoy the view. Not only does condensation ruin your view, but it can also lead to serious damage to your windows. Here is a closer look at what causes window fog and condensation in double-paned windows:

Foggy Window

Water Vapor

Water vapor is present in the air at all times and is the cause of condensation and window fogging. When air is warm, these water molecules are spaced far apart and travel through the air. As the air cools down, the water molecules get closer together and settle on solid surfaces. Water molecules collect on the surface of the window because it is typically the coolest surface in a room.

Indoor Air Humidity

Humidity in your home’s indoor air will cause condensation on your windows. Activities such as cooking and showering will increase the moisture content of your air. To temporarily reduce your indoor humidity, you can open your windows. If humidity and condensation become a regular problem, you will need to contact a ventilating contractor to help you improve your home’s ventilation.

Dangers of Condensation

Double paned windows are treated with gas or silica pellets that are designed to absorb moisture. When these absorbent materials fail, you will notice condensation building up between the window panes. Over time, this moisture will lead to damage to the windows. The surface of the glass can become etched from water damage, and your windows may no longer properly insulate your home.
