Insulating Glass

Insulating glass (also referred to as insulated glass) refers to two or more lites of glass sealed around the edges with a gas 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 an effective means to conserve energy and comply with building codes.
