How to Prevent Misted Windows
The accumulation of moisture on the inside of your double glazing is caused by many factors. Most commonly, the air inside your home is more vaporous than outside and can cause moisture to get trapped between glass panes.
It's a problem that could drastically reduce the effectiveness of your double glazing. In the absence of addressing the issue, it can result in higher energy costs and damage to your windows.
Condensation on the exterior
If you notice condensation on the outside of your window panes don't worry, this is normal. Exterior window condensation is caused by cold glass coming into contact with warm, humid air. When air moisture gets into contact with cold surfaces like window glass, it transforms into water droplets. Window condensation in the exterior is most common in the morning when the temperatures outside are cold and the sun hasn't yet heated the windows and evaporated the moisture.
The good news is that condensation on the exterior of your windows means your double glazing is operating well and is preventing heat from escaping your home. The bad news is that the excessive condensation from the outside of your windows can trickle down to cause peeling paint, blistering or cracks on your window frames. This can cause expensive damage and replacements.
You can do this by wiping off the condensation on your exterior windows with a squeegee, or a clean cloth. You might also consider a hydrophobic coating for your windows, which is a clear layer of substance that causes water to roll off rather than sticking. It is available in most hardware stores and apply it according to the instructions of the manufacturer.
Another method of reducing excess humidity is by using a dehumidifier in your home. These appliances are available at most hardware stores as well as online retailers. They are extremely effective in reducing the amount humidity in your home.

Moisture can also cause wooden window frames to decay and end up losing their structural integrity. The good news is that a damp examination performed by a qualified property inspector can identify the source of the problem and offer solutions that are cost effective.
Condensation inside
Sometimes, moisture gets trapped in your windows, in between the panes of glass. This kind of condensation is an issue in areas that are humid (kitchens, bathrooms and laundry). Most likely, it's caused by the different temperatures between the outside and indoor air. The warmer air in the indoor cools the glass to below its dewpoint, allowing water molecules to condense on the cold surface. This results in visible droplets of water or fog to appear on the window.
Fogging in between your window panes is usually an indication of a weak seal in the double or triple-paned windows. The insulating materials that are between the panes of windows, like argon, are designed to prevent warmth from passing through the glass into the room. However, as the seal deteriorates over time, moisture becomes capable of passing through. The result is condensation or visible fog in the middle of the window which makes it difficult to see out.
Moisture in between window panes could be a problem since it can cause mold and mildew. These are expensive to correct and are risky to your health. If not addressed it can lead to decay to wooden frames.
The best method to avoid this is to circulate the air inside your home, especially in humid areas like the kitchen and bathroom. Open the doors to the interior and switch on ceiling fans to bring dry, warmer air into these areas. This is better than keeping the doors and windows closed, as this will trap the moisture inside and stop it from dispersing quickly.
If you're seeing condensation on the inside of your windows, even in cold weather and when the air is dry, it may be time to get a new double-glazed windows that have insulation that is more durable. You can also add inert gases like argon to your windows to reduce the possibility of them reaching their dewpoint and developing condensation. This is a cheap and easy solution that will make your older, inefficient windows much more energy efficient.

The spaces are sealed using Hot-Melt sealant to ensure that the double glazed unit will be water and airtight. If this is not the case due to the aging process, damage or a poor installation then moisture will begin to build up between glass panes, which appears to be misty.
Repairing misted Windows
