A crack or break in a black sealant that holds the glass panes and the silver spacer bars is the primary reason for a double-glazed failure. The sealant, also known as hot melt, is a tough material that is susceptible to damage. If it's damaged it will allow air to enter the double-glazed unit causing condensation and misty window.
To repair a misted window you need to start by removing any 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. Always be careful when using a knife on any kind of glass or pane, as too much pressure can easily scratch it.
After the sealant is removed, take off the glass's top layer and place it on a flat surface safe where it won't be damaged. When the glass is removed, it is a good idea to mark the glazed face on the glass using a permanent marker that can help to put it back into the correct place.

Windows are an important aspect of any home because they provide lighting, ventilation and a connection to the outside. Unfortunately, they are also a major source of energy loss. The gas in double-glazed windows can deplete over time, resulting in condensation and less insulation. However, this can be prevented by regular maintenance and high-quality installation.
Most people believe that a misty window is an indication of damaged frames, but it rarely occurs. It's usually the seal that has failed and allowed the insulating gases between the glass panes to escape. The most efficient method to correct this is replacing the seal, instead of the entire window. This is a much cheaper option that will save you money in the long in the long run. It is also an excellent opportunity to upgrade your windows to energy efficient A-rated glass, which will further increase your savings.
Double-glazed units that fail are also called steam-up windows. This occurs when the hot melt sealant which creates the seal between two panes fails. Over time, this leads to a build-up of moisture within the window that cannot escape. The moisture will then become cool and then expand into liquid form. This can be seen as steam streaks appearing on the inside surface of the double-glazed window. It's more apparent during warmer days.
The issue might initially appear to be solved by blowing warm air through the window. While this may be helpful, it's not an effective solution for the long term. It is also important to avoid extreme temperature changes, as this can cause condensation and cause moisture to build up. Keep the temperature as constant as is possible.
