Double glazing is an excellent way to improve the efficiency of your property and ensure optimal energy efficiency. If you notice that your windows are getting misty it is an indication that the seal of your window has broken. This will allow moisture into the insulation portion of your windows and cause a drastic decrease in performance. This is a simple issue to solve. What is it? It is possible to see condensation on your double-glazed windows, particularly when it is very cold and stormy. This is a normal indication that your double-glazed windows are blocking out the cold but also let in warmth. It can easily be wiped away, or you can leave it to clear by itself. If your double-glazed window mists on the inside, this is a bigger problem. This usually means that the seal on your double glazing has failed or failed as it is called in the trade. When glazed seal unit breaks down, or fails, water can get in between the two panes of glass in your window. The argon, xenon and krypton gasses that are used in these units may also escape. Once this happens the high density gases lose their insulating properties and your window no longer a sealed unit. One of the primary reasons for the seal of a window to wear out is normal wear and tear that occurs over the years. The constant expansion and contraction of your double-glazed windows are caused by temperature fluctuations. Using abrasive chemical cleaners on your double glazing could also cause damage to the seal, and lead to it failing over time. If the seal on your double-glazed windows is broken, it means that warm air can escape between the glass panes, and cool air can enter, causing condensation to form on the spacer bar inside the glass unit. This is referred to as a "blown" window and could lead to expensive energy bills during the winter. This issue can be resolved by replacing the glass
