Are Your Windows Fogging Up?

Now that the weather is getting colder, you might notice moisture building up on the inside of your windows. It isn’t a cause for panic, but excessive moisture forming on your windows could be a sign of a problem with the window itself. Double pane windows are designed to insulate against the cold weather outside, but when they fail, they are no longer efficient.

The way double pane windows work is that they have a gas in between the panes that doesn’t conduct heat. This will only be effective if it is completely sealed in there, but what happens over time is that the silica desiccant that keeps it sealed wears out and lets air and moisture in. Many times you can notice the window turning foggy when this happens. Usually, this problem is more common on windows that are exposed to the sun a lot, since the heat will cause the gas between the windows to expand and contract as it heats up and cools down, wearing out the seal over time.
