Window Condensation: How does it happen, How to reduce it.
Under certain conditions, condensation can occur both inside and outside your home but windows do not cause condensation. The source of condensation, or “sweating” on windows and mirrors inside a home is caused by humidity, or invisible water vapor, present in virtually all air. When this water vapor comes in contact with a surface, which is at a temperature below what is called the “dew point,” the vapor turns to visible droplets of liquid, or condenses on the cooler surface. This often happens to bathroom mirrors and walls after someone has taken a hot shower. Condensation can also occur on windows during the winter if the inside humidity level is high enough.

This is air infiltration, and it is the result of air pressure differences between the inside and outside of the home. Every home has some level of air infiltration.
