Information on Single Pane Windows, Double Pane Windows and Triple Pane Windows

On the market currently, there are three types of window panes: single pane, double pane and triple pane. Single pane windows consist of one pane of glass separating the inside of your home from the outside. This type of window is the least efficient due to the lack of insulation it provides. Single pane windows are often combined with storm windows or solar screens, however both provide little to no insulation from harsh weather conditions.

Double pane windows consist of two panes of glass. The panes are separated and sealed which creates an insulated pocket of air. To further insulate the space between the panes, they can be filled with either argon or krypton gases. These gases have a higher resistance and let less heat escape through the panes of glass. Today’s double pane windows typically include a low-emissivity, also referred to as low-e, coating that helps further insulate the window. Although windows that have a low-e coating are slightly more expensive than single-pane non-insulated windows, they have the potential to reduce energy loss by as much as 30%-50%.

Triple pane windows are comprised of three panes of glass. Between each pane the space is filled with an inert gas, such as krypton or argon, which acts as an insulator. The added benefit of triple pane windows is that there are two spaces available to fill with this gas, inherently further insulting the window and preventing heat loss.
