Insulated Glazing unit

Insulated Glazing Unit or Insulating Glass Unit (commonly referred to as IGU) is a set of two or more lites of glass spaced apart and hermetically sealed to form a single glazed unit with an air space between each lite. Its most important function is to improve the thermal performance of glass when used in architectural applications. Another name often used in North America is Sealed Insulating Glass (abbreviated SIG).

The most commonly found IGUs are double glazed, i.e. made with two lites of glass and are therefore also referred to as "double glazing units" or "DGU" (especially in Europe) but IGUs with three lites or more, i.e. "triple glazing" are sometimes used for in very cold climates. Insulated glazing may be framed in a sash or frame or in a curtain wall. IGUs are also commonly used for replacement windows.
