Standard sealed units consist two glass panes sandwiched with a hollow spacer (shown above). The inside of the spacer bar is perforated and the spacer bars have been filled with desiccant to absorb any moisture. The two glass panes will be sealed together, and the entire unit will be filled with gas in order to improve its thermal efficiency.

As you can see, if the sealed unit fails, moisture can get between the panes causing condensation and mist. This could also result in heat escaping your property which could result in a significant amount of money being lost in energy costs.
