Dual-pane thermal windows have two pieces of glass sandwiched around a sealed section of inert gas, such as argon or krypton. This slows the transfer of heat and cold because temperatures have to pass through multiple layers to reach a home’s interior. Despite their superior energy efficiency, insulated windows experience unique problems, including fogged glass. If you’ve noticed this happening on your fixtures, here’s what you should know to correct the issue.

How Do Insulated Windows Become Cloudy?

A dual-pane window gets foggy when condensation collects in the section between its two panes.

This shouldn’t happen when the inert gas is tightly sealed, since insulating gasses don’t contain moisture. However, over time, the seals that hold the panes in place can wear down, allowing air through. When temperatures drop, the ambient air in between the panes cools, which can create water droplets along the pane. When the weather warms up, the droplets may dry and leave behind fogginess.

How Is Fogged Glass Corrected?

Once the seal that holds the inert gas in place has worn down, condensation continues forming inside the window. The fixture also loses its insulating capabilities.

You don’t need to have the entire fixture replaced if the frame isn’t damaged. However, you must replace the glass to ensure a tight seal between the panes. This corrects the fogging and moisture issues and also provides more effective insulation for the home.
