Double glazing is an excellent way to improve the efficiency of your home, and to ensure the highest efficiency in energy usage. However, if you notice that your windows are misting, it is an indication of a damaged window seal. This will allow moisture to get into the insulation portion of your window. This can dramatically reduce the performance of your windows. Fortunately, this issue is fairly simple to fix. What is it?

When this happens the high-density gasses lose their insulation properties, and your window no longer functions as an enclosed unit.

This is caused by the constant expansion and contraction of the gases inside your double-glazed windows when temperatures fluctuate. Utilizing chemical cleaners that contain abrasives on your double glazing can also cause damage to the seal, and cause it to break over time. If the seal on your double-glazed windows has failed this means warm air can escape between the glass panes, and cool air could enter and cause the condensation of moisture to occur on the spacer bar in the glass unit.
