[[File:New-windows-installed.jpg|thumb|Double panel windows, also sometimes called dual pane windows, are windows that have two panes of glass inset into the frame of the window. The panes of glass are separated, creating an insulating air pocket that inhibits heat transfer much better than single pane windows.]]

''Double-paned windows'' have two parallel panes (slabs of glass) with a separation of typically about 1&nbsp;cm; this space is permanently sealed and filled at the time of manufacture with dry air or other dry nonreactive gas. Such windows provide a marked improvement in [[thermal insulation]] (and usually in acoustic insulation as well) and are resistant to fogging and frosting caused by temperature differential. They are widely used for residential and commercial construction in intemperate climates. In the UK, double-paned and triple-paned are referred to as double-[[Glazing (window)|glazing]] and triple-glazing. Triple-paned windows are now a common type of glazing in central to northern Europe. [[Quadruple glazing]] is now being introduced in Scandinavia.
