Double glazing is an excellent method to boost the efficiency of your property and ensure maximum energy efficiency. However, if you notice that your windows are misting, then this is usually an indication of a damaged window seal. This allows moisture to get into the insulation section of your window, which could drastically decrease their performance. Luckily, this issue is quite easy to resolve. What is it?

Once this occurs, the high-density gases are no longer able to provide insulation and your window will no longer function as a sealed unit. One of the primary reasons for a window's seal to fail is the natural wear and tear over the years. The constant expansion and contraction in your double-glazed windows are caused by changes in temperature. Using abrasive chemical cleaners 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 is damaged the warm air could escape between the glass panes and cool air could enter and cause moisture to build up on the spacer bars inside the glass unit. This is referred to as a "blown" window and can cause costly energy bills during the winter. Replacing the glass
