If your double-glazed windows are difficult to open or have a mist between the panes this could be the result of faulty seals. If this is the case, it will be worth arranging for them to be fixed.
This can be accomplished without replacing the windows and is much cheaper in the long run. This kind of repair requires very specific tools and equipment, so it's recommended to leave this work to an expert.
Seals that are damaged
Window seals are what keep the gas argon or Krypton between panes of glass in triple or double-pane windows, and they can be worn out over time. A broken seal allows air from outside to enter, and the argon gas used to insulate your home to escape. Both are detrimental to energy efficiency.
Window seals are susceptible to damage due to extremes in humidity, temperature, and pressure. These changes can make your window glass to expand and contract. This causes pressure on the seals. This is also a possibility when you have pets or children who accidentally bang against your windows.
If the seal on your window breaks, it's a good idea to have the issue looked at by a professional as quickly as you can. If you wait too long for too long, the argon and krypton gas may escape completely, which can significantly decrease the insulation properties of your window.
