Insulated window glass consists of two or more panes of glass separated by a piece called a spacer. The spacer creates a cavity of air between the two panes of glass. An adhesive is applied to the spacer creating an airtight, watertight seal that traps the air or gas within the cavity between the two panes.

This trapped still air reduces the conductive heat transfer between the interior of your house and the outside environment. The entire assembly – glass and spacer - is often referred to as an insulated glass unit

The insulating properties of an insulated glass unit are expressed as an R (for resistance)-value or R rating. The higher a window's R rating the greater its resistance to heat transfers. For instance, a standard insulating glass unit consisting of two clear uncoated panes of glass with air in the cavity between them has an R-value of 2.
