These windows are called insulated glass units (IGUs) and may also contain an inert gas like argon or Krypton to further limit the transfer of heat or cold from the outside to your home. As with all manufactured products window seals also have an extended life span and can eventually fail from normal wear and tear, or damage caused by external forces such as high winds or improper installation. However, they also suffer due to environmental factors like solar heating and cooling, humidity and even the use of harsh cleaning products. If window seals fail, they allow humid air between the glass panes of your IGU leading to condensation that obscures your view. This can lead to increased cost of energy as well as water damage, and an increase in the insulation properties of your windows. A sure sign of a failing seal is a window that is unable to longer be wiped down to get rid of the moisture that has encroached on the view.
