triple glazing

Three-pane window system

Triple glazing is window construction using three panes of glass with insulating gaps between them, offering superior thermal and sound insulation compared to double glazing.

Common in cold climates and energy-efficient buildings: The Scandinavian house came with triple glazing throughout.

The term also works as a verb: We're triple glazing the north-facing windows.
