They are also damaged by environmental factors like solar heating and cooling, or humidity, and even harsh cleaning products. If window seals fail, they allow moisture to get between the glass panes of your IGU, causing condensation that obscures your view. This can not only reduce the insulating value of windows, but it can also lead to increased energy costs and water damage to the home.
