Double glazing is a great way to improve the efficiency of your home and guarantee the highest efficiency in energy usage. However, if you notice that your windows are misting, then this is usually a sign of a broken window seal. This will allow moisture to get into the insulation section of your window, which can dramatically reduce the performance of your windows. This problem is easy to solve. What is it? There may be condensation on the outside of your double-glazed windows at times especially when it's cold and windy. This is a normal indicator that your windows are working effectively, keeping cold out and the warmth in. You can wipe it away or let it go on its own. If your double-glazed window has a tendency to mist on the inside this is a more serious issue. This is typically a sign that the seal on your double glazing has failed or failed as it is called in the trade. The moisture can get inside the two glass panes in a double-glazed unit that has failed. This can cause the argon,xenon or the krypton gas used in these windows to leak out too. Once this occurs the high-density gasses lose their insulation properties and your window will no longer function as an enclosed unit. One of the main reasons for the seal of a window to break down is natural wear and tear over years. The constant expansion and contraction of double-glazed windows is caused by temperature changes. Using abrasive chemical cleaners on your double glazing could also cause damage to the seal, and cause it to break over time. If the seal on your double glazed windows is damaged it means warm air can escape between the glass panes, and cool air could enter, causing condensation to form on the spacer bar in the glass unit. This is often referred to as a 'blown window' and could result in costly energy bills throughout the winter. Replacing the glass units of your
