Condensation on windows and French doors is generally regarded as a problem. You might be surprised, however, to know that this is often not the case. Renewal by Andersen® of Kansas City shares an in-depth look at what causes window condensation and what you should do if you see it on your windows.
What Causes Window Condensation?
Condensation forms when moisture in the air comes in contact with a surface with a much lower temperature. For example, a cold bottle of drink will form condensation on its surface not because of its contents but because of the moisture in the surrounding air. Another example is when your eyeglasses turn foggy when you leave a cold room.
The same thing happens when condensation forms on your windows. During winter, it’s not uncommon for condensation to form on closed windows or even on installations as big as sliding doors. During summer, condensation may form on the outside. It doesn’t mean that there is something wrong with your windows. In fact, it’s quite the opposite in most cases; it means your window and patio door seals are intact.
What You Should Do With Condensation
You might be wondering why condensation should form at all since windows are supposed to be insulated. A long-winded explanation about thermodynamics will likely bore you, but let us give you the short answer: insulation works by preventing heat transfer since it is heat that moves to cooler spaces. This means that an insulated window is supposed to be cool, as heat cannot get through the other side. Therefore, when condensation forms on your windows, you’ll need to address your indoor humidity levels by using a dehumidifier or by regularly ventilating the rooms in your home.
There is one exception that you should be aware of. Windows with insulated glass are equipped with double-pane glass assemblies. The space between the glass panels is sealed to minimize conduction between interior and exterior surfaces. If you notice condensation between the glass, this means the seals around your windows have failed and will have to be repaired.
