17 Reasons Not To Not Ignore Misted Double Glazing
Misted Double Glazing

Double glazing that is misted is a sign of damaged seals that allow moisture pass through the gap between the panes. This could reduce your windows' insulating properties and lead to a myriad of issues.


Condensation occurs when warm, humid air is in contact with cold surfaces, and cools to its dewpoint. If this process isn't managed your windows could become hazy.

Reduce Indoor Humidity

If your double-glazed windows mist because of humidity or water in the air. This water will condense on the cold surface like the glass of your windows.

If you want to prevent misting, lower the humidity inside by keeping the space ventilated and using extractor fans in rooms that tend to be steamy, such as bathrooms and kitchens. This will help prevent condensation on your windows by keeping the humidity at a minimum in these rooms.

Another simple method to ensure that your double-glazed windows free of mist is to ensure that there is always a large gap between the panes. If the gaps are too close, then moisture will be able to enter and the seal will crack which can result in windows becoming misty.

It is also a good idea to leave the windows as wide as possible in the daytime, particularly in the summer. This will help keep your home cool and fresh, and will also prevent warm air from getting through the gap.

Also make sure that you keep your blinds and curtains away from windows. Curtains that are placed against the glass can cause condensation to form on the inside surfaces of the windows, and it can also cause misting if there is too humid air.

The insulation properties are a major aspect that determines a window's resistance to condensation. Double-glazed windows are made from two separate glass panes sealed together with an interlocking bar that is placed between the glass. The spacer bar is constructed of dessicant which is designed to absorb and hold water vapour from the air. The silica in the spacer bar will let the water vapour out when the window cools and prevents it from reaching the dew point.

Your windows' insulation can be affected by a variety factors, including their age and the quality of their installation. Chemical cleaning products can also damage the seals, allowing moisture in and warm air out, and this can lead to your double glazing becoming misty. Make sure to use only window fitters who are registered with FENSA to minimise the danger. Always follow their instructions.

Clean Your Windows Regularly

If you are unable to reach your windows using ladders, a long extension rod and a squeegee will allow you clean your windows while standing on the ground.

It is normal for the exterior of windows to mist up after the air has warmed up and reached its dewpoint. It can occur on any surface that is able to cool down, such as windows made of glass or double-glazed. It does not affect the performance of the window, and it is easily removed.

If condensation is forming in the windows, it could be more problematic and may require the attention of a professional. The reason for this is the window seal being defective, which allows moisture to enter and cold air to escape. The seal can be damaged by how the windows were originally fitted or by a chemical cleaning product used on them, or even the aging process.

A double-glazed window consists of two panes of glass separated by an air gap, and sealed together with a high quality thermal barrier like argon gas for better insulation. This makes the window extremely difficult to break. The air gap between the glass is then filled with a primary and a secondary seal that improves thermal efficiency and prevents moisture from getting into the window. Over time, the seals could break down due to a variety of factors, including age, the way windows were constructed and cleaning chemicals.

The water that is in the air gap transforms into water vapour when it's colder outside. This gets deposited on the outside of the window as a cloudy layer of condensation. The problem with this is that it reduces the effectiveness of your windows as an insulator, letting cold air in and warm air out, making your heating bills increase.
