Damaged Seals
Window seals are what keep the gas argon or Krypton between panes of glass in triple-pane or double-pane windows, and they are prone to wear out as time passes. If you've got a damaged seal, outside air is getting in and the argon that helps to insulate your home is escaping both of which can be 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 expand and contract. This puts pressure on the seals. This can happen if your children or pets accidentally bang on your windows.
