Cloudy, foggy, moisture in dual pane windows
You have probably seen this happen in dual pane windows. You may not even think it is a problem, except the window looks a little cloudy and hard to see through. It usually starts by looking like a dusty window that need to be cleaned. Over time, the window gets more and more foggy and harder to see outside clearly. Then one day you notice that the glass actually looks wet – it may even have droplets running down between the two panes of glass in the dual pane window.
We see it here in Placerville, down in Sacramento, and just about anywhere that there are dual pane windows installed. It actually is moisture that has accumulated inside the window. How does the water get inside the window? Glad you asked. As the window gets older the gasket can fail, allowing moisture to get inside. The windows now has lost its insulation value and condensation begins to form between the two pieces of glass.
