Insulated glass units can help maintain comfort within a home. These windows often feel considerably less drafty than single-pane windows, allowing the home to feel cozier on a cold winter day. Insulating windows will also allow less hot air into the space on a hot day, meaning the air conditioner will be able to maintain a more constant temperature throughout the day.
Insulated glass is a unit made up of two or more panes of glass sealed and sandwiched together with an air space between them. This space is filled with air, argon, or krypton gas. This system keeps interior and exterior air temperatures separate more efficiently than single panes of glass.
The term “insulated glass” is somewhat of a misnomer. The glass itself is not insulated, but the unit as a whole is. This unit consists of the exterior glass pane, a spacer bar around the perimeter of the glass, a seal, a desiccant material to absorb moisture, and the interior pane. The spacer bar creates a consistent, even gap between the glass panes, leaving space for the inert gas. Some insulated glass units (or “IG units”) feature three or four panes, with gas filling the spaces between them.
Insulated glass does just what it says in the name, insulate the home from outdoor temperatures. Plus, they help reduce energy costs.
