It is crucial to identify the cause of the problem and then fix it. Glass that is smudgey can be an indication of old windows. There are many reasons your windows may have become blurred. Damaged Seals A damaged window seal is the most frequent cause of foggy or misty windows. Modern windows feature a triple or double-pane glass that has an air space between them, and are sealed with a vacuum around the edges. These windows are called IGUs, or insulated glass units (IGUs) and could contain an inert gas, like argon or Krypton, to further reduce the transfer of heat or cold from the outside to your home. As with all manufactured products window seals also have an expected lifespan and may eventually fail due to normal wear and tear, or damage caused by external forces, such as high winds or poor installation. They may also be damaged by environmental elements like solar heating and cooling, or humidity, and even harsh cleaning products. When window seals fail they allow moisture to enter between the glass panes of your IGU leading to condensation that obscures your view. This can result in higher costs for energy, water damage and an increase in the insulation properties of your windows. A definite sign of a failing seal is windows that cannot longer be wiped down to remove the moisture clouding the view. This usually happens when the moisture inside the window has grown so that it has surpassed its capacity to be desiccant. If this happens it is the time to contact a window specialist. The best way to avoid seal failure is to follow the manufacturer's care instructions, which are typically printed on the inside of your window frames. It is also recommended to avoid high-pressure cleaning of your windows as this can harm the glass and seal. In
