Double glazing is an excellent method to boost the efficiency of your home, and to ensure optimal energy efficiency. If you notice that your windows are misting, then it's usually an indication of a broken window seal. This will allow moisture into the insulation portion of your windows, which can decrease their performance drastically. Fortunately, this issue is fairly simple to fix. What is it? You might get condensation on the exterior of your double-glazed windows at times particularly when it's cold and windy.

Once this happens the high-density gases lose their insulating properties and your window no longer a sealed unit. One of the main reasons for the seal of a window to wear out is normal wear and tear over years. This is caused by the constant expansion and contraction of the gases within your double glazed windows as temperatures change. Cleaning with chemicals that are abrasive on your double glazed windows can cause damage to the seal and cause it to break in time. If the seal on your double-glazed windows has failed, warm air can escape between the glass panes, and cool air can get in creating moisture on the spacer bars within the glass unit.
