Misty double glazing happens when the air-tight seal that holds the two panes of glass in a double glazed window fails. This allows moisture into the window and reduces its insulating properties.
Repairing your windows professionally is cheaper than replacing the entire window. This can help you avoid any further damage or condensation issues.
Seals
The window seal (also called a uPVC seal) is vital to ensure that your double-glazed is in top condition. If your window seals have been damaged or worn out, they'll no longer be airtight, which can lead to drafts, energy loss, and even misty glasses between the glass panes.
A window seal that fails will also affect the efficiency of your home's heating system and increase the amount you pay on energy bills. Typically, 20% of the heat that is lost in your home is lost through doors and windows and this is more noticeable when the window seals fail. If you notice a window seal failure it's crucial to get it repaired as quickly as possible to minimize the impact on your home.
The primary reason a double glazed window becomes foggy is because the seal breaks or fails and allows air to get between the two panes of glass and causing fogging and condensation. This can be due to many factors like the age of the window (seals do not last for long) and weather conditions, and the way in which the windows were originally constructed.
You can repair a misty window by drilling a small hole and blowing warm air into it or by filling the gap with clear cement. These solutions are only temporary and will not fix the issue which is a damaged window seal. If you wish to avoid the expense of repair, it's best to consult an experienced glazing expert who can replace the window seals, and then restore your double glazing to optimum condition.

Gaskets
The gasket holds the two panes of glass together in your double-glazed window. It can be damaged by a number of reasons, but it's usually caused by wear and tear or inadequate installation. This causes a misty appearance due to the accumulation of moisture between the glass panes. There are many solutions to the issue.

Sealant
If the seal between the frame and glass has broken down then moisture could enter and cause mist. The majority of the time it is due to wear and tears or simply ageing. As temperatures decrease and rise the gases inside the double-glazed unit expand and shrink, which causes pressure on seals. It could be a result of poor installation or damage during construction.

The most common reason for a failed double glazed unit is a crack or break in the black sealant which holds each pane of glass and the silver spacer bar. This sealant is called hot melt and is a pretty tough material so if it is damaged, it will allow air to enter the double-glazed unit, causing condensation and a misty window.
To repair a window that is misting it is necessary to begin by removing any old sealant. You can make use of a sharp knife however it is better to use some sealant remover as this will make the job quicker and easier. Always be careful when using a knife on any kind of glass or pane because excessive pressure could easily scratch it.
Remove the top glass pane and place it in a flat area in a place that will not be damaged. Once the pane is out, it is an excellent idea to mark the glazed face on the glass using a permanent marker that can help you put it back in the correct position.
You'll require a top-quality replacement sealant for double-glazed windows. It must be weather, thermal and water resistant, and be able to join the two panes of glass together and the frame too. Using cheap, low grade sealant will cause the glass to degrade more quickly and will also be less durable.
Glass
Windows are an essential part of any home, offering lighting, ventilation and a connection to the outside. However, they can also be a significant source of energy loss. This is because the gas inside double glazed windows can deplete over time, leading to misted glass and lower insulation. However, this could easily be prevented by regular maintenance and quality installation.
Most people think that a misty double-glazing window means the frame has failed, but this isn't the case. It's usually the seal that failed, allowing the gasses that are insulating between the panes of glass to escape. The most efficient method to correct this is replacing the seal rather than the whole window. This is a much cheaper alternative and will save money in the long run. It's also an excellent opportunity to upgrade to energy-efficient glass that is A-rated, which will also increase your savings.
Double-glazed units that fail to function are also known as steamed up windows and they occur when the hot melt sealant which forms an airtight seal between two panes of glass fails to seal the glass. This causes moisture to accumulate within the window over time. The moisture will then become cool and then expand into liquid form. This is evident as steam-like streaks appearing on the inner surface of the double glazed window. It will appear more severe on days with warmer temperatures.
The issue may initially appear to be solved by blowing warm air through the window. While this may help, it is not an all-time solution. Avoid extreme temperature changes since they can lead to condensation. Maintain the temperature as steady as possible.
