How Energy Efficient Are Double-Glazed Windows?

How Energy Efficient Are Double Glazed Windows

The vast majority of modern replacement windows are double-glazed, meaning that the glass portion of the window unit is actually made with two panes of glass. These two glass panes do not touch but are separated by a spacer, and the area in between the panes of glass is filled with gas—typically argon or krypton—that acts as an invisible insulator. For the sake of visualization, think of it as a gas sandwich in which the glass panes are the slices of bread. Many people wonder how energy efficient double-glazed windows are, and the answer to this question depends on a number of factors, such as how the window is manufactured and what climate it is formulated for. However, it is generally safe to assume that double-glazed windows are considerably more energy efficient than single-glazed windows, which feature only one pane of glass and no insulating gas pocket.

How Double Hung Windows Work

Double-glazed windows are more energy efficient than single glazed windows because they feature twice as much glass, which means it won’t be as easy for hot air to escape your home in the winter, or enter your home in the summer, through the natural process of thermal transmission. Also, the argon or krypton gas fill between the panes of glass on double-glazed windows will further prevent heat from transferring through the window unit. What’s more, because double-glazed windows often feature spacers that keep the edges of the glass panes warmer, the surface of the glass is able to maintain a more consistent temperature and is not as easily influenced by interior and exterior temperatures. This can also help to reduce the occurrence of thermal transfer.
