Double glazing is an excellent method to boost the efficiency of your home and ensure optimal energy efficiency. However, if you notice your windows leaking, it is an indication of a damaged window seal. This can allow moisture to enter the insulation area of your windows and can reduce their performance dramatically. Fortunately, this issue is quite easy to resolve. What is it? You might get condensation on the exterior of your double-glazed windows at times especially when it's cold and windy. This is a typical indication that your double-glazed windows are securing the cold, but letting in warmth. You can clean it off or let it go away on its own. If your double-glazed window has a tendency to mist on the inside this is a more serious issue. This usually means that the seal on your double glazing has broken down, or 'failed' as it is called in the field. Moisture may get in between the two panes of glass in double-glazed units that have failed. This could cause the argon,xenon or Krypton gas that is utilized in the windows to leak out as well. Once this occurs, the high-density gases lose their insulation properties and your window ceases to function as an enclosed unit. One of the main reasons for a window's seal to break down is natural wear and tear over the years. The constant expansion and contraction of your double-glazed windows is caused by changes in temperature. Double glazing seals can be damaged using abrasive chemicals. If the seal on your double-glazed windows has failed the warm air could escape between the glass panes, and cool air could enter and cause moisture to build up on the spacer bars inside the glass unit. This is often called a blown' window and it can result in costly energy bills in winter. Replacing the glass units in your double glazed windows can solve this issue. This is a far cheaper solution than replacing
