Double glazing is a great method to boost the efficiency of your home and guarantee optimal energy efficiency. If you notice that your windows are getting misty it is an indication that the window seal has been damaged.

If your double-glazed window has a tendency to mist on the inside this is a bigger problem. This is typically a sign that the seal on your double glazing has broken down or 'failed' as it is known in the industry. Moisture can enter between the two glass panes in the case of a double-glazed unit that has failed. The argon,xenon orkrypton gases that are employed in these units could also escape. When this happens, the high density gases lose their insulation properties and your window not a sealed unit anymore. Natural wear and tear is one of the main causes for the seals to fail on windows. The constant expansion and contraction of your double-glazed windows are caused by temperature fluctuations.

This is commonly described as a "blown' window and it can result in costly energy bills in winter. Replacing the glass units in your double-glazed windows could solve this
