Double glazing is a great way to increase the efficiency of your home and ensure optimal energy efficiency.

This could drastically decrease their performance. Luckily, this problem is relatively simple to fix. What is it? It is possible to see condensation on double-glazed windows, especially if it's cold and stormy. This is normal and a indicator that your windows are working well, keeping cold out and the warmth in.

This can cause the argon, xenon or krypton gas that is used in them to leak out too. After this happens the high-density gases lose their insulation properties and your window will no longer function as an enclosed unit. One of the primary reasons for the seal of a window to wear out is normal wear and tear that occurs over the years. The constant expansion and contraction in double-glazed windows is caused by temperature changes. Cleaning with chemicals that are abrasive on your double glazed windows can cause damage to the seal and lead to it failing over time. If the seal on the double-glazed windows you have is broken the warm air could escape between the glass panes and cool air can get in creating moisture on the spacer bars within the glass unit. This is commonly referred to as a 'blown window' and could result in expensive energy bills during winter. This issue can be resolved by replacing the gl
