What is Condensation?

Condensation is a process in which water vapor changes to liquid. The higher the relative humidity the greater the water vapor content. Maintaining a reasonable inside relative humidity of less than 60% is an important factor in preventing condensation. Relative humidity is a percentage measurement of the amount of water vapor present in the air in relation to the amount it is capable of holding at that temperature. Warm air holds much more moisture than cold air, thus condensation is created from warm air. The indoor relative humidity can be lowered by bringing in outside air that mixes with the inside air. The temperature at which the air is saturated and can no longer hold the moisture is called dew point. When dew point is reached, the air can no longer hold in moisture causing excess moisture to be released in the form of condensation.
