What are Triple Glazed Windows?

Unlike Double Glazing, Triple glazing contains three panes of glass instead of two within a sealed frame. Between each pane is a pocket of air or inert gas, such as argon; argon is heavier than air and blocks out the cold air for optimum insulation. The extra layer makes it difficult for warm air to escape.

The air gaps are too small to allow the air to circulate and therefore prevent heat transfer by convection. Because the argon gas is a poor conductor, it reduces the rate of heat loss through the window. You can see from reading this how it could benefit your home or property.
