When you have double-pane windows or glass doors, one problem you may encounter is the glass fogging up on the inside. This is known as window condensation. When this happens, it means your insulated glass windows have failed. If they are filled with Argon or Krypton gas, fogging also means that these gasses have evaporated. But what exactly causes window condensation?
The following are the top three reasons why insulated glass fails and causes condensation between the glass panes:
- The perimeter window seals break due to water exposure;
- The seals soften, weaken, and eventually break due to heat caused by direct sun exposure; and
- The seals fail due to old age.
While you cannot avoid eventual window failure in the future, it is best to know the main causes so you can prevent premature window condensation. It is also advisable to find a window provider that offers long or even lifetime warranties.
