Double glazing is a fantastic way to increase the efficiency of your property and ensure maximum energy efficiency. If you notice that your windows are leaking this could be a sign that the seal on your window is broken. This allows moisture into the insulation portion of your windows and cause a drastic decrease in performance. Luckily, this problem is quite easy to resolve. What is it? You may see condensation on the exterior of your double glazed windows from time to time especially when it's cold and windy. It's normal and a indication that your windows are operating well, keeping the cold out and the warmth in. It is easy to wipe off, or let it clear by itself. This is more likely to happen if your double-glazed window mists inside. This is an indication of a broken seal or failure in your double glazing. When a double glazed seal unit breaks down, or fails, moisture can be able to get into the panes of glass in your window. The argon, xenon and krypton gasses that are used in these units can also escape. After this the high density gases lose their insulating properties and your windows are not sealed anymore. Natural wear and tear is one of the main causes for the seals to fail on windows. is caused by the constant expansion and contraction of gasses inside your double glazed windows when temperatures fluctuate. Cleaning with chemicals that are abrasive on your double glazing could also damage the seal and cause it to break in time. If the seal on your double-glazed windows is damaged it means warm air can escape from between the glass panes, and cool air can get in and cause the condensation of moisture to occur on the spacer bar within the glass unit. This is commonly called a blown window' and can cause costly energy bills during winter. This problem can be solved by replacing the glass units in your double-glazed windows. This
