Double glazing is a great method to boost the efficiency of your property and ensure optimal energy efficiency. However, if you notice your windows leaking, then it's usually a sign of a broken window seal. This will allow moisture into the insulation section of your windows and can cause a drastic decrease in performance. Luckily, this problem is quite easy to resolve. What is it? It is possible to experience condensation on your double-glazed windows, especially if it's extremely cold and windy. This is normal and a sign that your windows are operating effectively, keeping cold out and the warmth in. You can clean it up or let it go away on its own.

When a sealed double glazed unit breaks down, or fails, water can get inside the two panes of glass that make up your window. This can cause the argon, xenon, or Krypton gas that is utilized in the windows to leak out as well. After this happens the high-density gases lose their insulation properties and your window no longer functions as an enclosed unit. Natural wear and tear is among the main causes for the seals to fail on windows. This is caused by the constant expansion and contraction of gases inside your double-glazed windows as temperatures rise and fall. Double glazing seals can be damaged by using abrasive chemicals on them. If the seal on your double-glazed windows has failed, it means that warm air can escape between the glass panes and cool air could enter, causing condensation to form on the spacer bar within the glass unit. This is known as a "blown" window and could cause costly energy bills during the winter. Replacing the glass units of your double-glazed windows could solve this problem. This is a cheaper alternative to rep
