Argon windows are more efficient than air-filled double-pane and triple-pane windows, so they can help lower your home’s utility bill over time. Argon glass has recently gained attention as an energy efficient tool that anyone can use for their home. To make the right decision, you need to know what argon is, why it is commonly used in windows, and how argon windows compare to other windows. Double-glazed windows can be filled with argon gas to help insulate the room and minimize heat transfer through the window glass. Argon gas is a colorless and odorless gas that has been used by window manufacturers for years.

What is argon gas?
Argon is a gaseous element whose symbol is Ar in the periodic table. It also makes up about one percent of the atmosphere. It has long been used in other household products such as fluorescent tubes and light bulbs. Because argon is cheap, safe, odorless, and diffuses quickly in well-ventilated areas, it serves a variety of industrial purposes. Argon is found in luxury car tires, window frames, and diving suits. Argon is also used in electric arc welding.
Argon should last a long time if the window quality is good. It is normal for windows to leak some argon over a period of time, but good windows can keep argon inside the window for 20 years or more. Even if a small amount of argon remains, it is still an effective insulator.
Homeowners who are concerned about their windows can have them checked by a professional to find out if argon is still inside. If the gas has completely leaked, fog or frost may be visible between the panes.
Using argon gas in double-glazed windows
Argon is used to fill the space between double-glazed and triple-glazed windows. These types of windows are known as “gas filled”. To fill the jars, argon is pumped in through a small hole along the spacer, while air is allowed to escape through another small hole in the spacer. Therefore, one way homeowners can tell if their windows are made with argon is to check for these holes.
Argon gas does not conduct heat, so it is an excellent insulator. Gas-filled windows also prevent frost formation on the bottom of the window in cold weather. Argon is one of two types of gas that may be used in windows for this purpose. Another gas is krypton.
Argon is naturally present in the air
Is argon gas safe?
Argon is a natural, non-toxic and non-reactive gas found in the environment. If the window seal breaks and argon leaks out, there is no harm to the environment or the residents of the house. The gas diffuses rapidly in an open, well-ventilated environment. Window specialists can use a special meter to detect the presence of gas in windows.
Argon can be replaced using special tools. To replace argon, gas is pumped in through a hole in the spacer. If the seal breaks, the window may need to be repaired or replaced, or the problem will reoccur.

Argon vs krypton gas
Krypton is denser and more expensive than argon, so although it is a better insulator, it is much less popular. Argon windows are the industry standard because argon is a reliable and readily available gas. As mentioned, argon works best in the 1/2-inch spaces found between double-glazed windows, while krypton is more effective in the smaller spaces between triple-glazed windows. Therefore, some homeowners who choose to purchase triple-pane windows choose krypton instead of argon gas filler.
Advantages of argon gas windows
Argon gas is a very good insulator, it works best in summer and winter. Whether it’s hot or cold outside, argon gas windows provide insulation in all temperatures and climates. Argon is also safe for humans and the environment.
Argon helps insulate against noise, which can be useful for homeowners who live in noisy areas.
Compared to other gas fillers, argon is relatively inexpensive and therefore a practical option for homeowners as well as business owners.
These windows can improve the performance of a home’s air conditioning system and therefore can lower utility bills over time.
Works with almost any design. Argon works best in double pane windows spaced 1/2 inch apart, but apart from that, any size or shape of window will work with argon covers.
The insulating properties of argon can prevent frost on windows in winter.
How does argon gas work to make windows more efficient for your home?
Since argon gas is denser than air, adding it to the glass unit in double-glazed windows improves thermal insulation efficiency. Argon gas windows keep the window temperature closer to room temperature. This process ultimately eliminates the currents and drafts that occur when different temperatures collide.
While argon injection into double-pane windows can be more expensive initially than cheaper, air-filled double-pane windows, the long-term energy efficiency benefits are well worth it.
Argon is a colorless and odorless gas.
