It is bright and sunny outside, and there has been no rain for days. Yet water droplets are on your windows. The scientific term for these droplets is condensation. Window World Twin Cities discusses the causes of window condensation.

 

What is Condensation?

Condensation is simply the water vapor in the air  that forms into water droplets on hard surfaces. For a natural example, condensation occurs outdoors on the grass or other surfaces every evening. The more humid the air is, the more condensation occurs. The colder the surface, the more water vapor from the air collects on the surface. 

 

Sweaty Windows - AKA Window Condensation

In the winter when it is cold outside, condensation can form on the inside of your windows from the humid air in your home. In the summer, condensation can form on the outside of your windows from the humidity outside. Sliding glass doors are prone to condensation because of the large surface area. Cold air holds less moisture than warm air. When temperature between the inside and outside of your home changes, the warmer air deposits its moisture on the cooler glass of the window.

 

Problems From Condensation

When condensation forms, it is simply an indicator of humidity in a space. Problems can occur if the humidity in your home is excessive. The recommendation for indoor humidity ranges from 30-50%. If the moisture in your home is high, it can cause major problems like mold or damage to furnishings. Here are some indicators of excessive moisture in your home:

 

●        Condensation remains on the window all day.

●        Condensation forms on walls and furniture.

●        Home smells musty.

●        Odors from cooking linger several hours.

 

Can You Avoid Condensation?

Anytime there is any humidity in the air of your home, there is a chance for condensation to form. Humidity in your home should be a good balance between too little and too much. For your health, you do not want to take all of the humidity out of your home’s air. 

 

If you have single pane windows, installing modern double-paned windows like ours increases the tolerance of your glass to humidity by over 25%. While you can’t avoid all condensation, you can reduce it by window replacement.

 

What About Condensation Between Window Panes?

If you have double-pane windows and there is condensation between the panes, it could be an indicator of a problem with the window. Most double-pane windows have argon gas between the panes that do not have moisture in it to condensate. Condensation between panes may indicate a seal has failed and allowed air to intrude into the space between the panes. If there is condensation between your double-pane windows, consult a professional window installer to examine your windows.
