Double pane windows are known for their excellent insulation properties. Homeowners install them for reduced energy bills and added comfort. However, old insulated glass windows can get foggy over time.
Commonly known as foggy double pane windows, weak seals, extra moisture, and aging can build up some fog in between two glass panels. The good news is that it can be fixed. We will highlight all possible reasons and some quick fixes to eliminate condensation in between window panes.
What Are Double Pane Windows?
Double pane windows consist of two glass panels. These glass panes have a space in between where the argon gas is filled. This space filled with gas helps the window maintain a consistent temperature within a room for a longer period of time.
Because of the unique construction, these windows can get foggy over time. Fogged-up double glass windows look quite dirty. On the plus side, they can be fixed using a DIY method (more on this later). Despite the fog issue, these windows perform great when it comes to insulating the space. They prevent the transfer of heat and cold air to aid maximum comfort.
Possible Reasons for Condensation In Between Window Panes
There could be many reasons for foggy double pane windows. Here are a few possible reasons.
1. Broken Seals
The dual pane windows have two seals. One is on the outer side of the window, and the other resides within the two panels. Both the seals help the window perform well under all types of conditions.
However, with time, the seals can get weak. They can often break as well. Usually, they break because of:
- No proper drainage system around the window. This causes water retention, which weakens the seals and eventually damages them.
- Aged dual pane windows (over 15 years old) also have weak seals. Therefore, when they are exposed to direct sunlight, their seals can break. Note that these windows usually last around 10-15 years.
2. Constant Sun-Exposure
The insulated glass windows expand and contract when they are exposed to direct sunlight for a long. This expansion and contraction weaken the efficiency of the window seals.
In short, the broken or weakened window seal causes fog to build inside it. Conversely, if the seal is in good condition, the chances of condensation in between windows panes are quite less.
DIY Method to Say Goodbye to Foggy Double Pane Windows
It can be stressful to live with fogged-up dual pane windows. However, with a DIY method, you can fix it. Here is the step-by-step process to follow.
Step 1. Drill a Hole
To get rid of foggy dual glass windows, you have to go a bit above and beyond to eliminate them. First, drill a hole in the top or button part of the window. Do not put any extra force while drilling to prevent any breakage.
Step 2. Place the Humidifier Next to the Window
A dehumidifier would eliminate maximum moisture from the window. Place it right next to the affected area of the window. Let it do its job until you see a visible difference.
Step 3. Plug the Hole
Once the fog cleans up, it’s time to plug the hole. Use weatherproof silicone caulk to plug the hole. It would prevent the further spread of any moisture.
Step 4. Clean the window
Now, take a microfiber cloth and clean all sides of the window. This would make the window look. Cleaner. Assuming that you follow each step carefully, you will surely see a noticeable difference.
Some Tips to Avoid Condensation in between Double Pane Windows
By following some essential measures, you can get rid of dealing with foggy double pane windows. As it becomes tough to clean them, it is best to prevent any condensation in between the two panels.
1. Improve Air Circulation
Poor air circulation is another common reason fog builds inside dual pane windows. Therefore, homeowners should work on improving the air circulation of their property. Especially in winters, it is better to turn on the room fans (at least for some time) to improve the airflow within the house. Opening the house windows for some time on a daily basis also improves the airflow.
2. A Raised Temperature in Winters Can Help
During winters, it is also essential to maintain a bit of a high temperature within the room. That’s because a high room temperature would eliminate the moisture. So, a lowered humidity level doesn’t let fog or haze build inside the windows.
3. Use Dehumidifiers
Dehumidifiers absorb moisture from the air. Installing a couple of them in your house can make some significant difference. If you have plenty of dehumidifiers installed in your house, you may not have to open your windows on a daily basis to prevent condensation in between window panes.

Final Thoughts!
So, that’s how you can clean foggy double pane windows. No doubt, it’s not an easy process. However, if done professionally, you’ll see noticeable improvement. It is also essential to maintain a good airflow within the house to avoid condensation in between window panes.
Furthermore, try to keep your double pane windows clean throughout the year. If you have way too old dual pane windows installed, replacing them would be the better option. Always invest in quality dual pane windows and buy them from reliable glass sellers.
Frequently Asked Questions:
Yes, a foggy double pane window can be fixed. However, it can get complex at times. Try to keep your windows clean and maintain good airflow.
There could be many reasons for condensation in between the window panes. The most common ones are broken seals, aged windows, and improper airflow.
A cloudy or foggy double pane window can be fixed using a DIY method. The best option is to replace it. However, using a defogging spray or removing the moisture by drilling a hole are also some cheap ways to fix it.
The weak or broken seal is the most obvious reason for cloudy windows. With time, the seal present between the two layers of double glass windows can leak. This causes moisture to form inside the window, which makes it look cloudy.
