Misty Double Glazing Repair Misty double glazing occurs when the air-tight seal which is used to hold the two panes of glass in a double-glazed window fails.

The gas in double-glazed windows can deplete over time, resulting in condensation and less insulation. Regular maintenance and quality installation can easily stop this. Most people think that a misty double glazed window means that the frame has failed, however this isn't the situation. It's typically the seal that has failed, leaving the insulating gas that is between the panes to escape.

It's also a great chance to upgrade to energy efficient glass A-rated, which can further increase your savings. Double glazed units that fail are also known as windows that are steamed up. This occurs when the hot melt sealant that forms the seal between two panes fails. Over a period of time, this causes a build-up of moisture within the window that is not able to escape. The moisture will then become cool and then condense into liquid form. This can be seen as steam streaks appearing on the inside of the double-glazed window. It's more noticeable on days with warmer temperatures. In the beginning, the issue might seem to be solved by adding warm air to the window. Although this can be helpful, it's not a permanent solution. Avoid extreme temperature changes as they can cause condensation. Keep the temperature as constant as possible.
