Insulated glazing. Insulating glass (IG), more commonly known as double glazing (or double-pane, and increasingly triple glazing/pane), consists of two or three glass window panes separated by a vacuum or gas filled space to reduce heat transfer across a part of the building envelope.
Your Window Is Supposed To Be Filled With Gas. Nearly all windows today, whether new construction or replacement, have two or three panes of glass. Single pane windows are difficult to find and are mainly confined to older homes (pre-1980s) or out-buildings (sheds, etc.) where energy saving does not matter.
