Interior window condensation is caused by an excessive amount of moisture in a person’s home. It is a common occurrence in the winter when warm air inside your home condenses on cold windows. Exterior window condensation is known as dew. You may see dew on your windows when they are colder than the dew point.

A balance of moisture in your home is critical in order to keep ice or moisture from forming on your windows. If your home has double paned windows condensation may be seen at 25-40 percent relative humidity. If you have triple pane windows you may see condensation at 30-50 percent.

Condensation occurs when water vapor, which is a gas, turns into water droplets. This happens when water vapor touches a cold surface.  The time when this happens (called the “dew point”) relies upon the temperature within the home. The hotter the indoor air, the more water vapor it can “hold,” and dampness can better stay in the vapor state. At the point when air moves alongside an icy window, the temperature drops and it can’t “hold” as much vapor. That is the point at which you begin to see buildup forming. 

The prescribed indoor moisture levels for a person’s well being run from 30-50. percent. Generally, we focus on the lower end of this range on account of the danger of buildup inside dividers and roofs. On the off chance that your home has satisfactory mechanical ventilation, mugginess is to a lesser extent a concern. 

What Can A Homeowner Do About Condensation? 


Ensure your house is appropriately ventilated. Try for under 40 percent relative humidity to keep both you and your home sound, and consider new windows. If window replacement is your goal check out our complete line of products at Murphy’s.

On the off chance that you as of now utilize mechanical ventilation and have low inside moisture, and are still having issues, you may need to look at your ventilation setting. Likewise, ensure air is permitted to circulate either passively or mechanically throughout the entire house. If you close the door to the bedroom, the air can become cold and moist enough to condense on windows.

Older, weaker or worn windows can create problems no matter what you do to your interior air. Faulty seals around operable windows, metal spacers between the panes, and poor insulation can cause the window surface to get cold enough for condensation to occur.
