Insulating glass is made with a space separating panes of glass for the same reason people used to install “storm windows” on their houses. Air that does not move is a good insulator. Most insulating materials are designed in a way that traps air to create small pockets of “dead air”. This is true about the fiberglass insulation in your walls, the foam plastic in your beer cooler, as well as your favorite sweater. When two pieces of glass are placed close together and sealed around the edges it creates a layer of dead air in between. If the space between is too wide, the air has room to move, that is why all insulating glass is better than single glass windows with a storm window over it. If the gap is too narrow, there is not enough air to act as an insulator, making it less effective. (more…)
