Misty double glazing occurs when the airtight seal that is used to hold the two panes of glass in a double-glazed window fails. This allows moisture to pass through and reduces the insulating properties of the window.

Seals
The window seal (also called a uPVC seal) is crucial to ensure that your double glazing is in good condition.

Sealant
If the seal between the glass and frame has been damaged, moisture may enter the frame and cause mist. This is typically caused by wear and tear or just ageing - as the temperatures change, the gases in the double glazed unit expand and contract, which creates pressure on the seal. This causes it to crack over time. This could also be due to inadequate installation or damage that occurs during construction.

The most common reason for failure of a 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 known as hot melt and is a tough material so if it gets damaged, it will allow air to enter the double-glazed unit which leads to condensation and misty windows.
To repair a window that is misting you must begin by removing the old sealant. It is possible to use a knife but it's best to use a sealant remover. This will make the job easier and quicker. When using a knife on any kind or glass pane be sure not to apply excessive pressure.
Once the sealant is removed, take off the glass's top pane and place it on a flat surface secure, where it will not be damaged. When the glass is removed, it is a good idea to mark the glazed face on the glass with a non-permanent marker to help you put it back in the correct place.
You will need a high-quality sealant replacement for double-glazed windows. It needs to be weather, thermal and water resistant and also be able to bind the two glass panes 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 house, providing lighting, ventilation and a connection to the outdoors. However, they can also be major sources of energy losses. This is due to the gas contained in double-glazed windows can be depleted over time, resulting in fogged glass and lower insulation. Regular maintenance and high-quality installation can prevent this.

Many people believe that a misty double glazed window indicates that the frame has failed, however this isn't the case. It's usually the seal that is failing, allowing the insulating gas between the panes to escape. This can be corrected by replacing only the sealed unit and not the entire window. This is a cheaper option that will save you money in the long in the long run. In addition, it is a good opportunity to upgrade your windows to A-rated energy efficient glass, which will further increase the savings you make.
Double glazed units that fail are also called steamed-up windows. This occurs when the hot melt sealant that creates a seal between two panes fails. This causes water to build up within the window over time. The moisture will then chill and condense into liquid. This can be seen as steam streaks appearing on the inside of the double-glazed window. It will appear worse during warmer days.
The issue may initially appear to be resolved by blowing warm air through the window. Although this can be helpful, it's not an all-time solution. Avoid extreme temperature changes since they can cause condensation. Maintain the temperature as steady as is possible.
