This is another term for a dual pane or triple pane window.

Insulating glass is a multi-glass combination consisting of two or more panes enclosing a hermetically-sealed air space.
ONE (1) GLAZING UNIT MADE UP OF TWO (2), SOMETIMES THREE (3) GLASS PIECES, UNIFORMLY SEPARATED FROM EACH OTHER, THEN PRESSURE AND HEAT SEALED. WHEN 2 GLASS PIECES ARE USED, THERE IS ONE (1) AIR SPACE AND THE UNIT IS SAID TO BE DOUBLE GLAZED; BUT, IF 3 GLASS PIECES ARE USED, THERE ARE TWO (2) AIR SPACES AND THE UNIT IS SAID TO BE TRIPLE GLAZED.
A combination of two or more panes of glass with a hermetically sealed air space between them, which may or may not be filled with an inert glass. Low-E insulating glass comes with a special low emissisivity coating to restrict the flow of radiant heat.
A combination of 2 or more panes of glass with a hermetically sealed air space between the panes. The space may be filled with an inert glass such as argon.
A window or door construction that combines two or more panes of glass. The spaces between the panes are hermetically sealed.
Two sheets of glass bonded together in a unit to enclose a captive air space. Units are constructed with a metal spacer inside the outer perimeter. The spacers contain desiccant material for absorbing and holding any remaining moisture in the air space. The outer edges of the glass are sealed.
Insulating glass refers to two pieces of glass spaced apart and hermetically sealed to form a single-glazed unit with an air space between. Heat transmission through this type of glass may be as low as half that without such an air space. It is also called Double Glazing.
Insulating glass is made up to two lites of glass separated by a spacer around the perimeter, with a sealant plied to bond the plates to the spacer to form a sealed unit. Insulating glass is common in multi-story office buildings and is being used more often in residential construction. For hurricane protec- tion, insulating glass provides the added benefit of placing two panes of glass, with the interior pane being lam~nated, between building occupants and exterior elements. Also, as hurricane-resistant code requirements move north, insulating glass is necessary to meet thermal requirements.
Fire-resisting glass fulfilling the criterion of E (integrity) and I (insulation).
Double- or triple-glazing with an enclosed, dehydrated, and hermetically sealed air space between the panes. The space runs from 3/16- to 3/4-ins.
A combination of two or more panes of glass with a hermetically sealed air space between the panes of glass. This space may or may not be filled with an inert gas, such as argon.
A combination of two or more panes of glass with a hermetically sealed air space between them. This space may or may not be filled with an inert gas. IG with a special low emissivity coating to restrict the flow of radiant heat is called Low-E insulating glass.
Two or more pieces of glass spaced apart and hermetically sealed to form a single glazed unit with one or more air spaces in between. Also called double glazing.
Two or more pieces, lights or panes of glass separated by a hermetically sealed air space, typically 3/16 to 1 inch wide. Manufacturing of insulating glass began in 1930.
Two glass components separated by an air spacer and hermetically sealed. Inherently, insulating glass increases a window's thermal performance.
Two or more lites of glass separated and sealed to form a hermetic airspace. The sealed space may contain air or be filled with an inert and denser gas, such as argon, to deepen the effect of dead air space.
Two or more lites of glass with a hermetically sealed airspace between the lites. The sealed space may contain air or be filled with an inert gas, such as argon.
Window or door in which two panes of glass are used with a sealed air space between. Also known as Double Glass.
Panels of glass separated by air space.
