What You Should Know About Foggy Windows

Windows tend to fog up depending on the weather condition or difference in outdoor and indoor temperatures. This fogginess or cloudiness generally disappears when there’s a change in humidity level or temperature. But windows that are constantly foggy are something different altogether.

What You Should Know About Foggy Windows

Foggy Windows May Indicate an Underlying Problem

Modern windows are usually designed with two layers of glass separated by a spacer material, filled with inert glass and sealed together at the edge. When the space between the two panes becomes foggy or hazy, it can only mean the seal has already broken, compromising the window’s insulating value and energy performance. According to experts, broken or damaged seals may occur due to partial pressure differentials between the temperature outside and the gas inside, causing the inert gas inside to naturally escape the window. Changes in atmospheric pressure, or just normal wear and tear over the years, may also result in window seal failure, which in turn allows for the fogginess between the panes.

How to Check for Window Seal Failure

It can be tricky to determine whether the seals in your windows have already failed. You’ll know for sure by consulting a trusted local window company, but you can still do some simple checking. For instance, you can:

  1. Clean the glass. You should clean both the inside and outside of your windows thoroughly. This way, you can confirm that the fogginess you see isn’t caused by grime or external moisture.

  2. Check for distortion. When the inert gas escapes from between the glass, sometimes, you’ll notice that the panes are beginning to bend or collapse slightly in the center. Look at the reflection of the glass from outside. If there’s distortion, it can only mean the window seal has already failed.

Make sure to deal with failed window seals promptly, not only to defog the glass, but to maintain your home’s energy efficiency as well.

"Excellent service and product! They checked in with me every few weeks while we were waiting for the order. I was impressed with Sam, who measured my windows and headed the installation crew. He was respectful and patient with his team. They cleaned up after themselves. Before the new windows I had huge windows that didn’t open. Now I feel much safer and get better temperatures in those rooms."

"My experience with Anderson Renewal was amazing! From the first meeting with Miranda to choose my windows and doors to the installation provided by Tim and his crew was a pleasure! I just bought a home built in the 1960's that needed new windows and a new double front door with sidelights. As everyone knows Anderson Windows are great, but it was the people I interacted with from Anderson that made it such a great experience. It took three days for the windows and door to be installed and they "worked" every minute they were here. My huge front door took most of the day to install because they had to put in a new header and other improvements to make it fit! They even put up new drywall on the inside. Many people in the neighborhood have stopped by to comment on my beautiful front door! I think the crew left my house cleaner than it was before they started! Constantly cleaning up after themselves. I am thrilled with my windows and feel lucky to have met the team at Anderson."
