Insulating glass unit

Listing ID #3592664

When multiple glass panes or "lites" are assembled into units, they are commonly referred to as insulated glass, double glazing, Double Glazed Units or Insulating Glass Units (IGU). Most IGUs are double glazed, but IGUs with three sheets or more, i.e. "triple glazing" are becoming more common due to higher energy costs. Insulated glazing may be framed in a sash, frame or in a curtain wall.
