Insert Gas Windows

About Insert Gas Windows

The thermal efficiency of double and triple glazed windows can be increased by filling the space between the glazing panels within the unit with an inert gas, such as argon, xenon or krypton. Argon, which has 34 per cent lower thermal conductivity than air, can improve a double glazing window’s U value or energy rating by over 30 per cent. Argon fillings last the lifetime of a double glazing window and over a period of 25 years should not lose more than five per cent.

Krypton and xenon are even more energy efficient than argon but are seldom used in double glazing window as they are more expensive.

BSW offers double and triple glazed argon gas windows. Argon is an inexpensive, non-toxic, odourless gas that is used on residential windows to prevent frost forming on the windows in winter bottom. Using argon also increases sound proofing characteristics of the window. Argon-filled windows are becoming an increasingly popular choice for many homeowners.

Argon gas windows offer better insulation than natural windows because the gas is denser than air. Triple glazed argon-filled windows provide two layers of insulation.

Argon gas windows deliver the following benefits:

  • Increased R-values
  • Improved soundproofing characteristics
  • Minimized heat exchange through the window
  • Reduces the possibility of condensation and frost
  • Protection from ultraviolet rays
  • Available in different commercial sizes depending on use
  • Argon will not corrode the window material as oxygen does
  • Heating and cooling systems work more efficiently where argon gas windows are installed
  • Can be used floor to floor ceiling, as sealed shorter windows or in an open/close design
  • Argon Gas Window Alternatives

As mentioned there are alternatives to argon filled windows.

Krypton filled windows are usually more expensive than argon, but krypton serves as a better window insulator. Krypton is used to fill thinner air spaces than argon, typically ¼ inch and 3/8 inch gaps between the panes.

These type of windows cost more than argon gas windows and twice as much as standard energy star rated windows. Krypton gas windows can reduce up to 40 per cent of a monthly energy bill.
