Double Hung

Benefits of Argon Gas Windows Argon is the gas most often used between panes in a double- or triple-glazed window. The gas is colorless and odorless,. Argon is denser than the atmosphere, providing more thermal efficiency than having air between the panes.

• What Do Filled Windows Offer? Added energy efficiency is the key benefit to having gas-filled windows. The gas acts as an insulator, working in both summer and winter to keep interiors protected from outside temperatures. Typically, gas infusion is provided in conjunction with applying a low-emissivity (low-E) coating film to the glass panes,.   The low-E coating and gas keep the interior pane of glass closer to the temperatures of the interior air, minimizing air currents that are created when different temperatures come into contact. This reduces drafts and cold spots.

Krypton is derived from a Greek word meaning, “the hidden one.” Because Krypton is a denser gas than Argon, it is also a better insulator. Krypton is a stable and chemically non-reactive gas, making it ideal for insulation. Krypton is more effective when the gap between window panes is narrow, which is why it is more commonly found in triple pane windows than double pane. Krypton is most effective in windows with around a 1/4”- 3/8″ gap. It only occurs in trace amounts within the atmosphere.

Comfort Select 73 is a durable hard-coated low-emissivity glass that provides passive solar gain resulting in year-round cost savings. Designed for use on the #3 surface, Comfort Select 73 offers a U-value of 0.29 and solar heat gain coefficient (SHGC) of 0.73 maximizing energy efficiency in the colder Northern region climates, where heating is dominant and the greatest energy concern.
