Glass with mist
The good news is that the majority of double glazing windows are repairable in the event that they're not damaged completely and the frame is in good condition. The frame isn't the reason for the issue it's the seal between the glass panes. The moisture in the air causes condensation between the glass panes. This can be caused by a variety of factors, including the humidity, heating and cooking washing clothes, and the general climate of your home.
Double glazed windows are sealed with a hot-melt adhesive between the two panes of glass and, sometimes, argon gas is added for an extra degree of thermal efficiency. This creates an insulating layer to prevent cold air entering your property and warm air leaving. In time, this may become less effective, causing condensation to form between the glass panes.
It can be incredibly frustrating It's worth noting that if the misting appears to be intense, then it might be time to replace your window. The seal has probably failed, allowing warm air to escape and cold air to enter. This will lead to a significant drop in energy efficiency as well as increased heating costs.

This will remove any dirt or debris that might accumulate over time, which could cause moisture to leak into the insulation gap. You can also switch to low-emissivity glass for additional protection, since this will help to block the transmission of heat through your windows.
If you're experiencing problems with your double-glazed windows, it is best to call an expert for repairs. You can attempt your hand at a DIY solution but it is not recommended since it could be dangerous without the proper equipment. Avoid using chemicals to clean your double-glazed window seals.

Smudged glass
Double-glazed windows are made up of two glass panes that are separated by an air pocket filled with a non-toxic gas, such as argon. The seal stops the gas that insulates from leaving and also blocks outside air and moisture entering through this space. When the window starts to fog up, it is a sign that this seal is failing and moist air is entering the window, where it is condensing, creating a cloudy appearance.
