Double glazing is a fantastic way to improve the efficiency of your home, and to ensure optimal energy efficiency. However, if you notice your windows misting then this is usually an indication of a damaged window seal. This can allow moisture to enter the insulation portion of your windows and cause a drastic decrease in performance. Luckily, this problem is quite easy to resolve. What is it?

This is due to the constant expansion and contraction of gases inside your double-glazed windows as temperatures change. Double glazing seals can be damaged using abrasive chemicals. If the seal of the double-glazed windows you have is broken the warm air could escape through the glass panes, and cool air can enter creating moisture on the spacer bars within the glass unit. This is commonly described as a "blown window' and could cause costly energy bills throughout the winter. This issue can be addressed by replacing the glass units within your double-glaz
