What is condensation?
Condensation generally occurs inside the home when it is freezing outside, and the humidity level inside the house is at a higher level than recommended. When it gets frigid out, the humidity level inside needs to be reduced accordingly to avoid condensation.
Where can it develop in a home?
Condensation typically develops on cooler surfaces inside the home, such as astragals, hinges, hardware, and glass. These surfaces are cooler because they are closer to the outside than a wall or table, and excess moisture condensates on these surfaces. Moisture in the air is known as humidity.
What causes condensation on windows?
Is it a sign of a faulty window? Learn what causes condensation and why it is normal. Condensation is actually a sign that windows and doors are doing their job. While it can be frustrating to look through a foggy window, the good news is you can minimize or prevent condensation with the proper knowledge.
So where is the water coming from?
An important fact to remember is the surface where condensation has formed is not obtaining water from outside the home, nor is it making its moisture; instead, it comes from the environment inside the house. The higher the humidity percentage inside the house, the quicker a cooler surface will begin to condensate. Air temperature, combined with humidity level, defines a temperature at which condensation will form. This is called the Dew Point Temperature. If condensation is developing, then the humidity percentage must be reduced, so the resulting Dew Point Temperature is below the temperature of the cooler surfaces.
