INSULATING GLASS
Insulating glass refers to two or more lites of glass sealed around the edges with an air space between, to form a single unit. Commonly referred to as an "IG unit", insulating glass is the most effective way to reduce air-to-air heat transfer through the glazing. When used in conjunction with low-E and/ or reflective glass coatings, IG units become effective means to conserve energy and comply with energy codes. The most common architectural insulating glass unit configuration is 6mm glass / 12mm air space / 6mm glass.
