Double Glazing

By Lee Wallender, About.com

Definition: Double glazing means two panes of window glass sandwiched together to create a middle buffer. "Glazing" is a specialized window term. People who work on window glass are called "glaziers."

This buffer can either be "dead air" or it can be a special gas such as argon. The idea behind double glazing is that the double panes of glass, plus the intermediate buffer zone, provide a better barrier against outside temperatures than single paned windows. Double glazing can be found with both new construction and with replacement windows. Initially created just for extreme climates, now window manufacturers are producing double glazed windows for nearly any location. Argon is a better buffer zone than air because it better inhibits passage of heat or cold into the house.
