Today’s energy-efficient replacement windows often consist of two or more panes. These double-paned windows provide even greater energy efficiency when the space between them is insulated with an inert gas. Most commonly, this gas is argon. Argon is a noble gas, or a gas that is odorless, colorless, and has very little chemical reactivity. Argon is an ideal gas fill for double-paned windows because it highly resists heat transfer, which improves the overall thermal performance of the window glass and the window frame.
Argon Basics
Argon is inexpensive, which makes it a great choice for replacement windows. Argon is also clear, so it does not affect the view at all between the panes. Replacement windows with argon gas fills typically have a spacing of about one half inch between the panes.
How Argon Insulates
Heat is readily transferred through glass itself. The molecules of glass are close together and easily transmit heat, while the molecules of argon are spaced widely apart and are nonreactive, meaning that they don’t move rapidly about or otherwise encourage heat transfer.
While quality replacement windows have several measures in place to improve their thermal efficiency, the argon gas spacer does double duty. The exterior pane of glass resists heat from the outside, while the interior pane helps to maintain the temperature inside your home. Between these two panes, argon gas halts heat transfer, keeping your window energy efficient.
