Insulating Glass Units
Insulating glass units, or IGUs, are designed to keep homes warmer in colder weather and cooler in warmer weather. An insulating glass unit commonly consists of two (sometimes more) panes of glass separated by a spacer material and sealed together at the edge. The insulating airspace is filled with air or a noble gas, such as argon or krypton inside, and some IGUs may be coated with special materials. This enables the glass to meet two very different requirements, keeping heat in during colder weather and keeping heat out during warmer weather.
