Contraction and Expansion
Seals in dual-pane windows may be damaged over time because of the expansion and contraction of the spacers that separate the glass. This is due to the fluctuations in temperature that occur throughout the day. As the glass expands as sun heats it the seal is put under pressure. When the glass cools during night, the seal on the window contracts. The constant contraction and expansion can result in a break in the window seal which allows humidity to get into the window, causing fog between the glass panes. The crack in the seal permits inert gases, such as the argon gas, which is trapped between the window panes to escape. This drastically reduces the insulation value of the window.

Weather Conditions
Window seals are designed to withstand harsh weather conditions. However, exposure to constant pressure could cause them to fail. Extreme temperature fluctuations can cause the glass within the window to expand and shrink. This puts pressure on the seal over time. This is particularly true for homes located in climates which experience hot summers as well as cold winters.
Storms, high humidity, and other environmental conditions can also cause damage to window seals. Wind specifically, can be particularly tough on windows, causing them to move or loosen over time.

The spaces between the glass panels are usually filled with inert gases such as argon and krypton, which helps to reduce the transfer of heat and cold outside the window. These windows are also known as IGUs, or insulated glass units (IGUs).
