Condensation on New Windows. Understanding What It Means

Condensation Inside and Outside your Windows?

You’ve probably noticed condensation on your windows, and when there’s condensation on the inside of windows, it can drip onto your floors and leave a wet puddle over time.

Of course, you want to know how to solve this problem. While it’s common with older, inefficient windows, there can be condensation on new windows too.

You’ve got questions, and we’ve got your answers, so let’s talk about the condensation on your windows! 

What Causes Condensation?

The science behind condensation is humid air meeting water droplets on any cold surface. So it makes sense that window panes have condensation because glass is colder than an insulated wall.

Why Does Condensation Form on the Inside of Windows?

It’s more concerning to many people when condensation runs down the inside of windows. When there’s too much humidity inside a home or building, that moist air reaches the cold glass and forms condensation.

What About Condensation on the Outside of Windows?

Anytime the weather goes from sunny and warm to cooler and dark as the sun sets, condensation may collect outside the windows, just like dew appears on grass.

Does Low-E Glass Reduce Condensation on New Windows?

Modern glass panes with a Low-E coating may cut heat transfer through your new windows by up to 50%.

This new type of glass means more comfortable living conditions inside a home, although you may still notice condensation outside your new windows in the wintertime. However, we have great news for you if you see condensation outside.

Condensation outside means the Low-E glass efficiently reflects heat and energy to stay within your home.

Why Is There Condensation Between the Window Panes?

The common reason for condensation or fog between window panes is leaky seals around the windows. These leaks mean moisture is seeping inwards between the window panes. It’s a warning sign that your windows need replacement. 

Do the Windows Always Cause the Condensation?

As we mentioned, condensation outside of new Low-E glass means the window is working correctly to keep energy inside your home.

When any window is well-insulated and installed correctly, it lowers the risk of heat or cooling losses in your home. This loss, in the form of airflow, generally causes condensation.

If there’s condensation inside your home on new windows, the humidity levels can be to blame. So let’s talk about how you can control it. 

How to Stop Condensation on Your Windows?

There are ways to promote better airflow in your home or building while reducing humidity.

These tips are especially helpful in Fall or winter:

  • Turn on exhaust fans in higher-humidity areas like your kitchen or bathrooms.
  • Use a humidifier when it feels humid inside, and turn it off when you don’t.
  • Ensure the vents on your dryer and gas appliances are clear and direct moisture outside.
  • If you have a fireplace with a damper, open it occasionally so moisture can escape. 
  • Allow airflow to circulate through your home from outside for a short time every day.

It’s best to know if there’s condensation inside the windows, outside, or between the window panes. What is more, this information can help to select the right windows. CWR can help answer those questions and provide you with more information.
