Double glazing is an excellent way to increase the efficiency of your home and secure optimal energy efficiency. However, if you notice that your windows are misting, it is a sign of a broken window seal. This allows moisture to get into the insulation area of your window and could drastically decrease their performance. This issue is simple to repair. What is it? It is possible to experience condensation on your double-glazed windows, especially if it's extremely cold and cold and windy. This is normal and a indication that your windows are operating well, keeping the cold out and heat in. You can wipe it away or let it clear by itself. If your double glazed window mists on the inside though this is more of an issue. This usually means that the seal on your double glazing has deteriorated, or 'failed' as it is called in the trade. If a double-glazed sealed unit breaks down, or fails, water can get inside the two panes of glass in your window. The argon,xenon orkrypton gases that are used in these units may also escape. When this happens the high-density gases are no longer able to provide insulation and your window ceases to function as an enclosed unit. Natural wear and tear is one of the main reasons that cause seals to fail on windows. The constant expansion and contraction in your double-glazed windows is caused by temperature fluctuations. Double glazing seals can be damaged using abrasive chemicals. If the seal on your double-glazed windows is damaged warm air can escape through the glass panes and cool air could enter and cause moisture to build up on the bars that hold the glass unit. This is often referred to as a 'blown' window and it can result in costly energy bills during winter. Replacing the glass units of the double-glazed windows you have can solve this issue. This is a much more cost-effective solution than replacing t
