The main cause of the 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, referred to as hot melt, is a strong material that can be damaged. If it is damaged it will allow air to get into the double-glazed unit, causing condensation and misty window.
To fix a glass that has been misted, you must first remove any sealant that is old. It is possible to use a knife but it's best to use a sealant remover. This will make the task easier and faster. Be cautious when using a knife on any glass or pane, as excessive pressure could easily scratch it.

Windows are an important element of any house, as they provide light, ventilation and a connection to the outside. However, they can be a significant source of energy loss. This is because the gas contained in double-glazed windows can deplete over time, resulting in misted glass and lower insulation. Regular maintenance and quality installation can help stop this.
Many people believe that a misty double glazed window means the frame has failed, but this is rarely the scenario. It is most often the seal that has failed and allowed the gasses that are insulating between the panes of glass to escape. This can be corrected by replacing the seal, not the entire window. This is a more affordable option that will save you money over time. It's also an excellent chance to upgrade to energy efficient glass A-rated, which will further increase your savings.
Failed double glazed units are also known as steamed up windows, and they occur when the hot melt sealant that forms a seal between the two glass panes fails. This causes moisture to build up within the window over time. The moisture will then chill and expand into liquid form. This is evident as steam-like streaks on the inside of the double-glazed window. It can also appear worse on warmer days.
Initially, the problem may appear to be solved by inserting warm air into the window. While this may be helpful, it's not an all-time solution. Avoid extreme temperature changes as they can cause condensation. Instead, aim to keep the temperature as stable as possible.
