Reduce Condensation on your Windows

Why do I get Condensation on my Windows?

 Why is it on the outside?

Outside condensation happens when damp air comes into contact with surfaces that are cool, such as glass. This happens when the dew point in the air is higher than the temperature of the glass. It happens most often in the spring and fall when a warm day is followed by a cooler night.

How does Low-E glass help reduce outside condensation?

Low-E glass reduces the amount of heat that escapes from the interior of your home to the outside glass surface. You can save up to 50% heat loss by using an efficient Low-E coated glass. Since the window is warmer on the outside condensation occurs. This actually shows that the low-E is working properly.

Why is it on the Inside

If there is high humidity in your home, it will form on the coolest surface. That is usually your windows. The warmer the air and the higher the humidity the more the moisture will condense on your windows.

Why does condensation form on the bottom of the sash?

As warm air cools it falls and drops to the bottom of the sash. It then condenses.
