Do Your Dual Pane Windows Have a Broken Seal?

Dual pane windows have two panes of glass and a space in between. That space is filled with air or gas, depending on the windows to provide additional insulating value. The glass in the windows is sealed to keep the air or gas in and to prevent dirt, debris and moisture from invading that space.

Unfortunately, window seals don’t last forever. Manufacturers use different materials to bind the glass to the spacer and create a seal and some are better and last longer than others. When the seal around the glass is in  your window is compromised, knowing the signs will help you decide when it’s time to get your windows repaired or replaced. Below are three signs that the seal around your dual pane windows has been broken. Here’s what to know.

#1. Condensation Inside the Window Glass

When the seal between two panes of glass begins to fail, the air or gas inside the windows may exchange for air outside the windows. If that air is humid, then your windows may fill with moisture. This moisture will appear to be “fog” or condensation on the inside of the windows. It may obscure your view, although just how much depends on the amount of moisture that penetrates between the window glass.

#2. Dirt Between Panes

In addition to moisture, you may start to see dirt between the panes of glass. This dirt may look like dust or like larger pieces of debris, depending on the size of the break in the seal. Over time, you’ll start to see more dirt between the panes of glass. In fact, you may even start to see some small bugs inside your windows.

#3. Frost or Ice Between Panes

When the space between your windows is infiltrated by moisture, at certain times of year, you may see frost or ice between the panes of glass. Of course, this will only be a problem when the weather outside is cold enough.

Unfortunately, any of these signs mean that your windows are no longer as energy efficient as they used to be. You may start to notice more drafts around your windows in winter. This is another sign that the air outside your home is starting to negatively impact the air inside your home.

Look for hot spots in the summer and cold drafts in the winter – this is a sure sign that your windows are leaking. These drafts are likely to put a burden on your home’s heating and air conditioning systems.
