Argon Gas Filled Window

The air in double and triple pane windows can be replaced with a heavier gas to reduce conductive and convective heat transfer through the window. Argon gas is the most common gas used, but other inert gases such as xenon or krypton can also be used. Gas-filled windows are now commonplace in colder climates.

In northern climate zones, gas-filled windows are becoming the only option on the market! Argon and krypton are the most popular gases used to displace the air between window panels. Argon is the most efficient of the two when comparing thermal barrier per dollar.</p><p>The windows must remain well sealed to contain the gas and to prevent air leakage through the window (airtight windows can be up to 33% more efficient). It can be obvious that a seal is broken when condensation begins to form in between the window panes. If this happens, the glazing can be removed and replaced by a glass specialist.

Gas-filled windows can achieve better thermal performance (lower U-factor) than typical air-filled windows, resulting in reduced heat loss. Typically they are coupled with low-emissivity coating, and together, an argon-filled, double pane window with Low-E coating can achieve a U-factor of up to 50% less. That means 50% better thermal performance!

Argon is a 'noble' gas that is colorless and odorless and is very common in the earth's atmosphere!
