Understanding Window Condensation

Condensation is caused by excess humidity in the home and appears on the coldest area of a wall. That is why condensation usually appears on windows. The warmer the air, the more moisture it will retain, therefore when the air comes in contact with the colder glass, the air is cooled and moisture is released on the glass.
